Admin login, How to find router’s IP address and modem username password IP address (some people mistakenly refer to 192.168.l.l) is the login page that is frequently used in the internet usage of any customer.

Usually you use address when you have Internet problems, Or if you want to change your wifi password.

However, there are also many manufacturers of modems, routers do not use as the default login address as or so sometimes you also attention.

Now we will explain to you why use this ip adress and when to use it.

What is is the IP address, the Internet Protocol acronym. Every computer is like a house, to get to the right place, the houses need to be numbered and the IP is given to do numbering.

This is the concept of evaluating addresses for devices in a computer network. The device may be a computer or a printer but usually it is your modem, your WiFi transmitter. Usually technicians use address as the default address for the network, Modem but still there are some devices selected default address is or some local range Other IPs.

How to access Router login

To access it, you need to connect your modem to the internet via Wifi or LAN port then open new tab in the Web browser like Google Chrome, Microsoft Edge, FireFox and enter the address of the browser tab.

access home gateway

Once you have access to the modem management page, you can change many settings such as QoS (quality management, network speed), DNS, Proxy, LAN, WAN, wifi password change, PPPOE dialing, block wifi access by MAC address or over IP, WPS, DSL, and many other advanced customizations.

For a normal user, you should not change the settings that you do not know because it can cause network disconnection, wrong network configuration that can not transmit wifi or very weak waves.

Why can’t login

Cause not to access the modem address a lot, which mainly causes the wrong access to the IP address of the modem.

Because the login address is not

As noted above, neither Modem line has the address, it can be or any address according to the manufacturer’s settings or has been changed by the previous user ( may be the installation staff). Therefore, you should refer to the IP Address Modem we mentioned above. not default ip

In case of failure to access due to modifications, you should proceed to reset your Modem. But if no knowledge of computer should not do because the reset Modem also means you have to reinstall network, or you can get help from the operator in this case.

Find your router’s IP address

With Command prompt

Press the Windows key and ‘R’ together and type ‘cmd’ then press Enter to open Command prompt. At the prompt type ‘ipconfig’ and press Enter. You will see a list of network adapters in your computer. Browse through the information to find the number next to Default Gateway. This is the IP address of your router.

Default Router IP Address List

Below you can find your router’s IP address. Once you know which is your router’s gateway, type it into the address bar. You will then have to introduce your user and password login credentials.

In case of wrong password is not rare because in addition to the default password, the installer has the right to change the password under the name of your contract. In this case, if you can not login with the default password, call the operator’s help desk as well as avoid resetting the modem.

The wrong password

Some modem lines have a lot of changes and do not follow the defaults.

So you need to know the username password.

Because the system has multiple transmitters

You will not be able to access of the Modem you are using if you are an extra device, not the sum and your network also has many WiFi Modem connected. At this point your IP address will be automatically allocated under Total Modem. And to resolve this situation you just need to disconnect from the net to access

Of course we usually do this to change the WiFi password or reset our WiFi Modem in case of need and then reconnect.

How to access a Wi-Fi network when you forget or do not know the password

In the busy world, you forget your Wi-Fi (WiFi) password at home or at work, or even want to access another Wi-Fi network without entering a password. All will be revealed in today’s article!

Each Wi-Fi modem is now equipped with the WPS feature, which is a new standard for accessing Wi-Fi networks easily and quickly.

WPS is equipped with two main features:

  • A WPS PIN is a sequence of numbers that gives you access to a Wi-Fi network instead of a network password.
  • The WPS button on the modem gives you access to your Wi-Fi network without entering any passwords.

Guide to Wi-Fi networks when forgetting passwords using WPS


  • This trick only works when the WPS feature on the modem is enabled (default enabled).
  • It is recommended to use WPS access to your owned Wi-Fi networks or you have permission to use them.
  • Need to use WI-Fi modem to operate.
  • This trick does not apply to devices running the iOS operating system.

Option 1: On your Android smartphone, go to Settings> Network & Internet (or Wi-Fi dependent on your device)> Wi-Fi> Select the Wi-Fi network to access.

Next flip through the modem to find and remember the WPS PIN (if any), then use this sequence instead of the Wi-Fi password. Option 1 will not work if the user has changed the default WPS PIN code provided by the manufacturer, you can use it in the second way with a 100% success rate.

Option 2: On your smartphone go to Settings> Network and Internet (or Wi-Fi depending on your device)> Wi-Fi> Scroll down and select “Wi-Fi Options”.

Then go to Advanced> WPS push button. At this point, the interface connected to the Wi-Fi modem will appear.

Now you need to find the WPS push button on the Wi-Fi modem, which will have the symbol “WPS” or two knit arrows on each other. After finding you just hold down the button on your Wi-Fi modem for 2-5 seconds and release it to automatically connect your smartphone to this Wi-Fi network without entering any passwords.

Very simple and fast right? Hope this trick will be “savior” for you in many cases need to access the Wi-Fi network.

How to hide IP address?

When leaving the house to public places like convenience stores, cafes and friends, you will not have to put your house number and address on your shirt. However, with the Internet, this will happen, the IP address (Internet protocol) is displayed. And there is nothing to worry about, but when something goes wrong you will wish to pay close attention, hiding IP in public.

What is an IP address?

Internet is a large area of ​​the website, the computer connection is processed and stored. To monitor computers on the Internet, each computer will connect to an IP address. It is like distinguishing houses on the street by the house number, except it is a long number.

Here are two types of IP addresses: IPv4 and IPv6. IPv4 was launched in the 1980s but is still widely used for Internet traffic. For 32-bit, only 4 billion addresses can be connected. An IPv4 address would look something like this: 168.90.0255.

IPv6 addresses are introduced as the weakest response of IPv4 addresses. They use a 128-bit address that provides a large number of options. An IPv6 address would look something like this: 2001: 0db8: 0000: 0042: 0000: 8a2e: 0370: 7334

Instead of typing a specific IP address into a web browser, it is called Domain Name System (DNS) . The domain name system converts from URL to IP. For example, when you start a web browser and enter the URL (for example, blogtip.org), DNS will detect and find the IP address of the web page, followed by the reverse display on the computer screen.

Mostly, IP addresses are automatically activated when you connect to the Internet, so why should we care?

Why hide IP address?

When seeing ads on a web browser, is it going on in your city? That’s not a coincidence.

Your IP address can be used to combat annoying ads, and it can be used for many malicious purposes. For example someone can find you when they know the address, similar they can trace you out when they know your IP address.

Hiding IP addresses is also a way to prevent hacking. This will prevent others from locating your location.

That is one of the many reasons you should hide your IP address. But below I will only have you some ways to help hide IP address.

Hide IP with proxy

Using a proxy server is the easiest way to hide your IP address, especially if you need to hide it immediately.

Servers work like a mask when you surf. When sending out a request, the server blocks or responds to the IP request. Stakeholders can see traffic between the computer and the server, so it is best to use it when processing sensitive data.

There are countless free servers available but they are often unreliable. If you decide to use a free server, make sure you do not exchange personal information with anyone else, and consider using a haschek-like server check. However, an article on Wired recently said the proxy server is becoming insecure.

While free servers are easy to find, install, and hide IP performance, the best way is to use a cost-effective and reliable server, often with a Virtual Private Network (VPN).

Hide IP with VPN

You do not know what VPN is and can be understood in the following article.

VPN works just like the server, it changes the IP address but provides protection for all Internet activity leaving your computer. As the information goes away, it moves to the VPN server from where it moves with another IP, making it hard for others to track.

Proxy is quite weak and there is no encryption between the computer and the server but with VPN, it installs an encrypted tunnel between your device. Your request will be forwarded to the open Internet, using a different IP address.

The only problem with VPNs is that it’s quite expensive. Desiring to watch unlimited geo-video may not guarantee a commitment price. However, with the era of cyber-security and spying, it’s never a bad idea to choose a VPN.


There are many other options to hide IP like the Onion Router (Tor) but to explain it differently because of the need for legality. Therefore, if you have ever used Tor, you will understand its legal and effective purpose. But it can still be used for illegal purposes.

No one needs to hide their IP address and business people who use the Internet do not have to worry. If you need security and privacy a little, hiding your IP is a must, and using a proxy, VPN or both will be a smart choice. And you do not have enough money for VPNs and would like to have another look at the free IP proxy look on the forums. Although this is not the best option.

7 Ways to Speed ​​Up Your Wifi

Let’s see what can be done to improve the wireless wave in the home.

Every month, you spend hundreds of thousands for your Internet service, but when the wifi waves also fall into an unacceptable situation? As a matter of fact, our first reaction is usually to spend “verbal attention” for network service providers. However, many of us do not know that the cause of the wifi signal is not guaranteed sometimes from … ourselves.


This is the way … the most original but also the extremely effective way. Even when setting up a network for a customer, some technical staff often refer to this trick for the user to use if the network is slow, lag, … The reason is because after a period of time Network connections will become unstable and flicker. If you realize that your network is showing signs of speed, go to your router, unplug the Internet cable, and then unplug the router from the power outlet. Wait for about 30 seconds (can wait longer if you feel the router is too hot) and plug the cable back to the Internet.

Please check that the jacks are secure, and do not forget to wait until the Internet icon (globe) lights up again. Now turn on the web and use it again as usual.


One of the most common misconceptions of online network users is that, regardless of where the router is placed, the wifi signal must be the same in your home, as the wifi signal … is across the wall. In fact, the thought is not wrong, because the wifi signal can go through objects such as walls, floors, …. However, this signal will be affected by small objects, As you know, the pillars, our floors are reinforced not only solid concrete. So just after a few walls, the wifi signal will be reduced, even lose the story is … very ordinary.

So, put your router in the most unobstructed, and centered as possible. From there, the wifi signal can be transmitted easily across your home or apartment. And do not forget to go straight to the sky for the antennas of the router, as it is the “posture” that it covers the strongest wifi signal.

3. Check your home network connections

In a simple and easy to understand way, your task in this way is to check whether any computer in your home is … downloading torrent, IDM or any other download service. The reason is probably that the tools will consume most of your Internet bandwidth, and then just surfing the Web may not be easy at all with you.


In big cities, where wireless networks are so common and can be found in most residential areas, the phenomenon of overlapping Wifi waves is not uncommon. And if you feel this has caused your home network to be affected, try changing your home’s Wifi channel.

This can be done easily by logging into the router from the web with the account provided from the network. Depending on the type of router you will have different configurations, you can refer to the accompanying documentation or search to see an item called Wireless Channel to select the channel change. However, you should use support software such as inSSIDer for Windows or Analyzer for Android devices to check which network channel is good enough for you to choose.

5. Check out wireless devices

One thing that few people know about are wireless devices such as old cordless phones, wireless speakers or microwave ovens that can use 2.4Ghz. That could directly affect the wifi signal – which usually uses this frequency to transmit signals (with 802.11 b, g, n standards). Wifi itself can operate on different frequencies and automatically change the frequency to reduce possible interference, but if you want to ensure that it can not happen, put The device is a bit away from the Wifi transmitter.


Current Wifi transmitters usually have a limited space for their broadcast range, and that is not to say the distance can be reduced through the walls, floors in the home. Typically for a high-rise building, the Wifi Broadband Generator can only handle coverage for 3 adjacent floors. So the waveguide (wave amplifier) ​​is the salvation for these cases.

Depending on the size of your home, allocate the location of these sets appropriately so that Wifi waves can spread throughout your home. Now wherever you are in your home, you will always receive Wifi “full” waves. However, it should be noted that these waveforms only spread the signal Wifi throughout your home, they do not work to make your Wifi stronger.

7. CONTACT WITH ISP (Internet service provider)

Wifi security: should use WPA2-AES, WPA2-TKIP or both?

Many routers provide WPA2-PSK (TKIP), WPA2-PSK (AES) and WPA2-PSK (TKIP / AES). Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access (WPA2) are the main security algorithms you’ll see when setting up a wireless network. WEP is the oldest Wifi security algorithm, so there are more security vulnerabilities. WPA has improved security, but is now also considered vulnerable. While WPA2 is not perfect, it’s currently the safest option. The Temporal Key Integrity Protocol (TKIP) and the Advanced Encryption Standard (AES) are two different encryption types used on networks that are secured by WPA2. Let’s see how they differ and what works best for you.

Compare AES vs TKIP

TKIP and AES are two different encryption types used by Wifi networks. TKIP is actually an old encryption protocol introduced with WPA to replace very insecure WEP encryption at the time. And TKIP is similar to WEP encryption. TKIP is no longer considered safe, so you should not use it.

AES is a more secure encryption protocol introduced by WPA2. AES is not a special standard developed for Wifi networks. However, this is a global coding standard even approved by the US government. For example, when encrypting a hard drive with TrueCrypt, it can use AES encryption. AES is often considered quite secure, and its main weaknesses are brute-force attack (which is prevented by using strong Wi-Fi passwords).

The short version TKIP is an older coding standard used by the WPA standard. AES is a new Wifi encryption solution used by the new and secure WPA2 standard. However, depending on your router, choosing WPA2 may not be enough.

While WPA2 is said to use AES for optimal security, it can also use TKIP for backward compatibility with older devices. In such a state, devices supporting WPA2 will connect to WPA2 and WPA-enabled devices will connect to WPA. So “WPA2” does not always mean WPA2-AES. However, on devices without the “TKIP” or “AES” option, WPA2 is usually synonymous with WPA2-AES.

“PSK”-“pre-shared key” – the encrypted password. Distinguish it from WPA-Enterprise using a RADIUS server to generate passwords on large corporate or government wireless networks.

Explain the Wifi security mode

Here are the options that users can see on their router:

  • Open: Open Wi-Fi network without password. Users should not set up an open Wi-Fi network.
  • WEP 64 (at risk): The old WEP protocol is vulnerable and you really should not use it.
  • WEP 128 (at risk): This is also the WEP protocol, but with better encrypted cryptography. However, actually it is not really better than WEP 64.
  • WPA-PSK (TKIP): Use the original version of WPA (mainly WPA1). It has been replaced by WPA2 and is not secure.
  • WPA-PSK (AES): Uses the original WPA protocol, but replaces TKIP with more modern AES encryption. It is provided as a stopgap. However, AES-enabled devices almost always support WPA2, while devices requiring WPA rarely support AES encryption. Therefore, this option does not make sense.
  • WPA2-PSK (TKIP): Uses the latest WPA2 standard with older TKIP encoding. It is also not secure and is only ideal if you have older devices that can not connect to the WPA2-PSK (AES) network.
  • WPA2-PSK (AES): This is the safest option. It uses WPA2, the latest Wifi encryption and the latest AES encryption protocol. You should use this option.
  • WPAWPA2-PSK (TKIP/AES): Some devices offer and even suggest this mixed mode option. This option allows the use of WPA and WPA2, with both TKIP and AES. This provides maximum compatibility for any legacy device, but also allows an attacker to compromise the network by breaking the vulnerable WPA and TKIP protocols.

WPA2 certification has been available since 2004, 10 years ago. In 2006, WPA2 certification became mandatory. Any device manufactured after 2006 with the “Wifi” icon must support WPA2 encryption.

Because your Wi-Fi enabled device can be “young” more than 8-10 years old, select WPA2-PSK (AES) only. Select that option and see if it works. If the device does not work, you can change it. In case of Wifi security is your concern, you should buy a new device manufactured since 2006.

WPA and TKIP will slow down Wifi

The WPA and TKIP compatibility options can also slow down wireless networks. Many modern Wifi routers support 802.11n and newer, and the faster standards will drop to 54mbps if WPA or TKIP is enabled. This will ensure they are compatible with older devices.

802.11n standard supports up to 300mbps if using WPA2 with AES. Theoretically, 802.11ac provides a maximum speed of 3.46 Gbps in optimum conditions. On most routers we see, the options are usually WEP, WPA (TKIP) and WPA2 (AES) – possibly WPA (TKIP) + WPA2 (AES).

If there is a router that provides WPA2 with TKIP or AES, select AES. As almost all devices will certainly work with it, and it’s faster and safer.

6 Simple Steps to Install Port Forwarding on the Router

Port Forwarding is the process of forwarding a specific port from one network to another, allowing external users to access the internal network by using that port from outside via a router (with NAT open -Network Address Translation).

Port Forwarding is widely used, especially for offices, schools and families with many computers connected to the Internet. The following article describes how to set up a port forwarding on a router.

1. Port Forwarding

Address the “inside” part of Network

Here’s how to get a simple Home Network map:

In the illustration you can see three computers with a single IP address on the same router. You can easily access other computers, however, when all of these computers access the Internet through a router.

Router has IP address related to your network. The router also has an external IP address that is used when interacting with your network. Whenever your computer requires Internet connection use the same IP address as

2. Port and Protocol

Port (port) makes the process easier. If the IP address is the same as the address of a building, the port is the same as the number of each apartment in the building.

When you visit a Web site, suppose you are using port 80. The PC-aware software will know that port 80 is used for the http Server and meets your requirements.

If you send http on another port, suppose as Port 143, the Web server will not recognize and can not meet your request.

Secure shell uses port 22 and VNC uses port 5900. These port may vary depending on usage, as there are many specific programs that are used for different purposes.

In order to avoid affecting other standard applications, it is best to use larger alternate configurations.

For example, Plex Media Server uses port 32400, Minecraft Server uses port 25565.

Each port can be used via TCP or UDP. TCP, also known as Transmission Control Protocol, is the most commonly used protocol.

UDP or User Datagram Protocol is less commonly used in applications except BitTorrent.

Address the “outside” part of Network

What happens when devices outside the system ask for connection?

Suppose if your computer requires the Home Network IP address, then connect to the router. However, Router does not understand to send back your computer.

In this case you can configure the router to forward the port. This means that depending on the number of port (s) required to be sent, the router can switch to other IP addresses.

When you access the Home Network IP address using port 22, your router will know that the address in the “inside” section of the Network is

Then the SSH daemon installed on Linux will respond to you. At the same time, you can send requests through port 80, your router will send to the Web Server at

Alternatively, you can remotely control your “sister” laptop via VNC, and your router will connect to

When you access the Home Network through the interface port 80, you can tell the router to send Web Server will listen to port 80 and respond to you.

However you can tell the router when you access through port 10000 that it has to access another computer, address and port 80.

3. Before configuring the Router

Before configuring the Router, you need to pay attention to some of the following:

1. If you are using DHCP, the IP address of each device is likely to change in the future. In some cases, you must reset Port Forwarding.

So the best way is to reconfigure the static IP address of “server” (the host).

Some routers have the ability to “reserve” or “specify” an IP address through DHCP, so that the IP address will not be changed. However, not all routers are just a number.

2. When you access an external network, you must know the external IP address of the router.

You can easily discover someone’s address in the “inside” section of Network by visiting whatismyip.com. This address may change. One way to avoid changing IP addresses is to redirect the domain.

3. Use custom ports that can activate your antivirus programs, software or firewalls. You must therefore add an exception on the host computer to allow external access to any port that you specify. However, security risks will be compromised, so you should be careful and take appropriate preventive measures.

4. Some brand Router

– Cisco / Linksys:

You can see Port Forwarding under Applications and Gaming. Under Single Port Forwarding you can add individual ports to specify IP addresses.

Under the Port Range Forwarding entry, you can easily move the entire port range at the same time.

– DLink:

On the DLink Router you can find the Pord Forwarding setting under Advanced in the Port Forwarding tab.

– Netgear:

The Netgear router has a menu of sections. Look in Advanced and then click on Port Forwarding / Port Triggering. If you use the Smart Wizard, you can configure Port Forwarding here.


Often, port forwarding in DD-WRT and third-party Router Firmwares applications and programs are included in the NAT/Quality of Service section.

Note that when you click Save to save changes on the DD-WRT Router will not take effect, you must also select Apply Setting.

5. Steps to set up Port Forwarding on the Router

Step 1: Enter your router’s IP address in the address bar of the Web browser

Enter your router’s IP address in the address bar of your Web browser to open your Router configuration page. Most IP address Router is or or However, if you want to find your router’s IP address to make sure you can follow the steps below.

  • For Windows: Open Command Prompt then enter ipconfig /all in the Search box. Your IP address is the same as the Default Gateway address.
  • For Mac: Open Terminal and enter netstat -nr.
  • For Linux: Open Terminal and enter Route.

Step 2: Enter your Username and Password

If you have set up Router protection then just enter the user name and password you created then proceed to login (Login). If you have not set up Router protection, follow the steps below to login.

  • With the Linksys Router, type “Admin” in both Username (username) and password.
  • For the Netgear Router, type “Admin” in the Username field and type “Password” in the password field.
  • For other routers you can leave without entering the Username, the password you type “Admin”.

If you do not remember your credentials, you can press the Reset button on the Router to reset all of your defaults. Then look for the default information on the online settings.

Step 3: Search for Port Forwarding

For each router will be slightly different. You can usually find in Port Forwarding, Applications, Gaming or Viral Servers. If you still can not find it, go to the Advanced Setting section to find Port Forwarding.

Step 4: Find the available configuration items

On many Routers, there is a Dropdown Menu (which displays the content and is a main Main Menu, when you click it, it will display the Submenus inside) with the configuration options available for many applications. If you want to open Port for an application, select it on the list.

Step 5: Create a custom item




If the program you want to add is not listed in the list, you will have to create a Port Forwarding. For each router, the steps are slightly different, although the information required on the routers is the same.

  • Enter the name of the application or program you want to add
  • Select protocol: You can choose protocol as TCP, UDP or both. Protocol depends on which program you are unblock. If unsure, you can select one of two TCP or UDP protocols.
  • Select the port you want to use. If you just want to open a port, enter Start and End the same number. If you want to open more Ports (about 5 Ports), you can enter 3784 in Start and 3788 in End.
  • Select the internal IP address to assign to Port Forwarding. This IP address is the IP address that runs on the application you are unblocking.

Step 6: Save settings

To save your settings, select Apply instead of Save. Then restart your router.


What is MU-MIMO? Why your next WiFi router should have MU-MIMO?

This may not be so important if you use Ethernet rather than WiFi, but think outside the box. Smartphones, tablets, Kindle, cameras, child monitors and many other devices only support Wi-Fi. With so many Wi-Fi enabled devices, MU-MIMO is even more important.

MU-MIMO stands for Multi-User, Muliple Input, Multiple Output. If you do not understand well, do not worry, this technology is simpler than the looks and benefits it brings is well worth knowing.

Wi-Fi prior to MU-MIMO

To understand the benefits of MU-MIMO, first of all understand how the traditional router operates. If you already know then you can skip and read later.

Prior to MU-MIMO, the wireless router was primarily based on the SU-MIMO technology, first introduced as the 802.11n Wi-Fi standard in 2007 and stands for Single-User, Multiple Input, Multiple Output. SU-MIMO allows the router to simultaneously send and receive data to and from a single device (Multiple Input/Output). Prior to SU-MIMO, routers can only send or receive at a time.

SU-MIMO has significantly increased the wireless data rate, but still has a big minus point, it can only send/receive data with one device at a time (Single-User). If your router is old or cheap, chances are it will only be able to operate on one device at a time.

The difference between SU-MIMO and MU-MIMO

This may not sound right. Currently, you may be using your computer, laptop, smart TV, and some phones, tablets, while they both use Wi-Fi at the same time. What is “one device at a time”?

Think of the SU-MIMO router as a dealer. There are 4 players on the table but the one who plays can only play for one person at a time. Imagine that each card is a data packet, which means that the SU-MIMO router will have to connect to each device in turn and quickly switch to another device, which means that they are connected at the same time. There will be a huge bottleneck because it’s just the 802.11ac Wi-Fi standard.

802.11ac Wi-Fi (Wave 1 and Wave 2)

There are a few things you need to know about MU-MIMO, which is the 802.11ac Wi-Fi standard. If you already know about the AC router, then read on.

802.11ac Wi-Fi standard is expected in 2013, six years after 802.11n. The new specs offer some improvements, speed up the Wi-Fi max but not all the changes immediately. The manufacturer has brought different aspects of 802.11ac in two phases: Wave 1 and Wave 2.

Wave 1 starting in 2013 only brings the features of 802.11ac supposedly less risky. For example, expanding the frequency from 40 MHz to 80 MHz and supporting 256 QAM modulation is quite simple, the manufacturer can issue a new prototype with these features and label the AC on it without even being able to. meets the standards.

Wave 2 starts in 2015 and brings with it the more difficult features of 802.11ac, the most important being MU-MIMO. If your AC router has before 2015, it does not have MU-MIMO.

What is MU-MIMO and why do you need it?

If SU-MIMO is a dealer, MU-MIMO is a divider with four pairs of hands, each of which will work with one player. MU-MIMO allows the router to split up individual packets and deliver to multiple devices at the same time.

Imagine you are watching Netflix on your computer, and your lover is using Skype on your phone. With SU-MIMO, the video may be jerky or degraded as the router often has to switch back and forth between the two devices to send data. But with MU-MIMO, it sends data continuously to both people.

Wi-Fi routers using MU-MIMO technology will be increasingly popular

Remember MU-MIMO does not speed up. It just keeps you out of the loop when connecting multiple devices, making the router not overworked. Instead of paying attention to each one, it will serve you all the time.

This is also a limitation because the router uses MU-MIMO technology only 2×2, 3×3 and 4×4 versions, meaning that it can only serve data streams between 2, 3 and 4 devices. If your router supports MU-MIMO 4×4, when using 6 devices, the router will have to divide the data stream and convert it to SU-MIMO.

Another minus point is that MU-MIMO signals work only on devices that can decode the 802.11ac protocol. This will not be worrying in the next few years. 802.11ac is becoming more popular but remember that older devices will not take advantage of this technology.


Wake-On-LAN (commonly called WOL) is the basic concept of enabling or starting a remote computer without having to press the power button as usual. In this article we will look at how Wake-on-LAN works and how to activate it.

What is Wake On LAN?

In essence, Wake On LAN is an industry standard protocol that is used to boot computer systems in extremely low power mode. The concept of low power mode is that we can understand that the computer is in a completely off state, but is still accessing the power supply. This protocol also adds Wake-on-Wireless-LAN functionality.

This is useful if you want to remotely access your computer for any purpose: It allows you to maintain access to files and applications, while your computer is kept in a low power state. electric bill). If you use the VNC or TeamViewer software regularly, or manage the data server, then Wake-on-LAN is much more convenient.

WOL depends on two main factors: mailboard (motherboard) and network card (network card). Specifically, your motherboard must be connected to a compatible ATX power supply, network adapter or wireless must support this feature. Because WOL is set up via the BIOS or the firmware of the network card, we do not have to use any other software to activate and configure it. However, you do not need to worry because most of the computer models, today’s motherboard has been integrated with this ability, even with the dedicated motherboard form, we can also set the time automatically. turn on and off.

And if you have to buy more network cards in the case of mainboard does not have built-in components, please fully understand the support WOL.

How does Wake-on-LAN WOL work?

Computers with Wake-on-LAN enabled will wait for a packet containing the MAC address of the network card, called the incoming Magic Packet. These Magic Packets are sent by specialized software, made for each platform or sent by a router or Internet-based website. Typical ports used for these Magic Packets are UDP 7 and 9. Since the host computer is actively waiting for packets, the power will have to be allocated to the network card, causing the laptop battery to drop faster, so if To save battery power without using WOL, you should temporarily turn it off.

Magic packets are routinely sent over the entire network and include complete information about the subnet, network broadcast address, MAC address of the network card on the target computer. The screenshot above is the result obtained from the packet magic packet with a packet sniffer tool, which can raise concerns for users using WOL over an insecure network or on the Internet. Common family, you can use without worry. Many well-known mainboard manufacturers include a number of support tools that come with WOL to meet the needs of the user, depending on the specific situation.

Activate WOL on Windows

To use Wake-on-LAN you have to enable it in several places – usually the BIOS and in Windows. Let’s start with the BIOS.

With BIOS:

Hầu hết các mẫu mainboard hiện nay đều có sẵn phần tùy chọn WOL trong BIOS. Trong khi khởi động, các bạn nhấn phím Escape, F2, hoặc Delete để truy cập BIOS, sau đó tìm trong phần Power Management hay Advanced Options hoặc tương tự:

Most motherboard models now have WOL options available in the BIOS. While booting, you press Escape, F2, or Delete to access the BIOS, then look in Power Management or Advanced Options or similar:

The screenshot above was taken from the HP laptop, the WOL option underneath the After AC Power Failure section in Power.

With some ASUS models, the Wake on LAN option is “buried deep” in the menu system, under Power on by PCIE / PCI, because the integrated network controller is behind the PCI controller.

Either way, many computer models do not have this option, or are too coarse to find it, but that does not mean we can not use WOL, instead you have to use the built-in customization function. operating system.

With Windows:

Click Start, open the Device Manager section and expand the Network Adapters section, right-click on the network adapter and select Properties> Advanced tab.

In the window that appears, scroll down to find the Wake on Magic Packet option and change the value to Enable, leave the settings on Wake on, then click OK.

Now, you click on the Power Management tab and make sure that: Allow this device to wake up the computer and only allow a packet packet to wake up the selected computer. Click OK to finish.

With Mac OS X:

Open System Settings> Energy Saver. You will see Wake for Network Access or similar option, which will enable Wake-on-LAN.

With Linux:

In essence, this open source operating system has a very good tool to test if your system supports WOL or not. Open Terminal and install ethtool with the following command:

sudo apt-get install ethtool

Command Compatibility Check:

sudo ethtool eth0

Change the network adapter’s eth0 value to eth0 as the case may be:

Here, go to the Supports Wake-on, if marked with g, we can use magic packet for WOL. And to activate this option, you type:

sudo ethtool -s eth0 free g

Then type the command as above to check again, looking for the Wake on section, we will see the g option instead of d as above:

WOL Magic Packet submission process:

To send WOL request information, we can use the following options:

Depicus has developed a number of lightweight and multifunctional tools to accomplish this task, including command line and graphical interface, supporting a variety of operating system platforms. If you would like to learn more about this process, please refer to here, or this article.

And if you want to turn on your computer using Android phone using WOL, and PC Auto Waker tool:

The basic functionality of PC Auto Waker is based on the 802.11 Wifi standard. The setup process is encapsulated in 3 steps. First, you need to enter the name of the computer to boot (not necessarily coincide with the actual name of the computer) – this is the step to identify any computer in the system:

Then enter the corresponding MAC address of the computer. And finally, enter the SSID of the network you are using. When done, move your computer to Sleep or Hibernate, then try the Wake All button on the main console of PC Auto Waker. If everything works according to our wishes then everything is finished, and if something goes wrong or is not working, then you need to check out some of the basic settings above.


How to increase download speed

There are many reasons why you do not get the maximum download speed. Here are some tips to help you increase download speed to get the maximum download speed on your device.


The biggest problem that slows down your download speed is from the modem or router you are using. If you are using a router or a faulty modem, your network speed will be greatly reduced. So, to ensure the best performance, make sure your modem and router are at the optimal speed under the network contract.


The next thing you need to do is make sure that your computer is not affected by the virus. Once the machine is infected, the system will be affected and your network speed will be significantly affected. At the same time, if you have installed pirated applications, they also affect the speed of your network usage.

So, make sure your computer is not infected with viruses or malicious applications.


The quality of the network cable and the length from the modem to the router or PC can also affect your internet speed. In order to optimize the transmission path, you should use good-quality network cables, replacing them after a long period of use and optimizing such that the length is as short as possible.


If your network speed is slow, turn off your modem for about 1 minute and then turn it back on. This is called “energy recycling” and can fix a lot of bugs that help speed up your internet. If possible, try configuring the modem you use, which will definitely bring about unexpected results.


Disable Update Delivery

The default Update Delivery feature is always available on Windows 10 Home and Windows 10 Pro. To turn off this feature just go to Settings> Update & Security> Advanced options> Choose how updates are delivered.

Here, you just turn off is finished.

Reserved bandwidth (Reserved Bandwidth)

On Windows 10, 80% of the bandwidth is used to serve the system and applications running on it. If you feel you do not need it, you can use up to 100% bandwidth by the way below.

First, open the Run application, and then type gpedit.msc to open the Local Group Policy Editor.

Here you go to Computer Configuration> Administrative Templates> Network> Qos Packet Scheduler> Limit reservable bandwidth and open it.

Now you just move from 80% to 0% to maximize your bandwidth.

Change the registry key values

First open the Run application (Windows + R key combination) and then type regedit, then enter.

Once the Regedit Editor has opened, you look to the left and expand the HKEY_LOCAL_MACHINE folder

Continue to expand the SYSTEM> CurrentControlSet> Services> Tcpip> ServiceProvider folder.

Here you change some of the values ​​as below:

  • In DnsPriority, you pass the value to 7
  • In HostPriority you pass the value to 6
  • In LocalPriority you pass the value to 5
  • In NetbtPriority you pass the value to 8.


Do not download multiple files at the same time

Do not download files during peak hours such as afternoon and evening. Try downloading files in the morning and at night to get the highest speed.

Verify that you are using a proxy or a VPN, as they will affect the transfer rate if non-standard settings.

Do not upload when you are downloading.


To optimize the download, using the support tools is indispensable. There are many downloadable applications but the most popular and effective is probably the Internet Download Manager. In addition, you can also refer to many software to speed up download on your computer.


This is the last resort because anyway the quality of the transmission line is the most important, without a quality input, all the above is just to bring maximum load bandwidth. If you want a significant improvement, you can upgrade to different packages within your pay range. At present, optical fiber is gradually becoming popular and the initial cost is very cheap. With just over VND 200,000, you already own the package with maximum download speed of 12Mbps, equivalent to 1.5MB / s. At the same time, the number is 1.3 to 1.4 MB / s higher than copper. IP address is the starting address of the IP address range for the private network, including all IP addresses to address So that IP address is usually not used on the network (on devices such as phones or computers not assigned this address). So what IP address is used?

Some networks that include addresses but do not start with this address can be used on devices without any problems.

On the router (router) is assigned a common IP address is This IP address is used because the router (router) is on the network. Similarly, the router on the network is usually assigned local address, the private IP address is

Why Useless Devices Address

Each Internet Protocol (IP) is comprised of a continuous range of addresses. The first number in the address range is used by the protocol to specify the entire network. The network number usually ends with a 0.

After address is set as the last network number will not be used for other purposes. For example, if an admin tries to assign as a static IP address to any device on the network, the entire network will stop working until it is offline.

Note that the address can still be used as the device address if the network is set up with a large IP address range (such as a network set from to

That is why IP addresses ending in zeros are rarely present on the network, except for the address.

How large?

The size of the network depends on the selected subnet mask. For example:

  • The address range between and has about 65,534 servers.
  • The address range between and has about 16,382 servers.
  • The address range between and has 254 servers.

Broadband home routers running on the network are usually configured to, which means that the device typically uses as the internal gateway address. This setting allows you to assign 254 devices on a network with a valid IP address.

Note: Home Network can handle multiple devices at the same time. If there are more than 5-7 devices connected to the router (router) at the same time will cause performance problems. This is not due to the limitations of the network, but because of signal interference and bandwidth sharing.

How to do it?

The dotted decimal notation of the IP address converts the actual binary number used by the computer into a form that the user can read. The binary number corresponding to address is:

11000000 10101000 00000000 00000000

Since this is a separate IPv4 network address, when pinging the network or connecting to the Internet or other external networks it can not route to is used as a network number so this address is used in the routing table to share network information between routers (routers).

Replacement Address

It is possible to replace the address with other addresses ending in 0, which address is a conventional problem.

As mentioned above, router (router) used in the family is usually installed address to log modem rather than address, ie the router can have its own IP address is so that you can log modem, network router.

After this article hopefully readers will know more about how it works as well as what IP address is used for. If you have any additional questions, comments, readers can leave comments, comments in the comments below. – The default IP address for some home network routers is the default local area network IP address for some home broadband routers including most Belkin models and some models from Edimax, Siemens and SMC. This IP address is placed on certain brands and models when first sold, but any router or computer on the local network can be configured to use it.

All routers have an IP address that you can use to connect to the router’s administrative console and configure the settings. You may never need to access these settings, as most home routers provide the same interface as the wizard that will help you make the installation. However, if you have trouble installing the router or you want to perform some advanced configuration, you may need to visit the router’s console.

Use to connect to the router

If the router uses, you can log on to the router’s console from the local network by typing IP into the address bar of your web browser:

After connecting, the home router prompts the user to enter the user name and password of the administrator. This username / password combination is factory-set for use on the first login and must be changed by the user to be more secure. Here are the most common default login credentials:

  • Belkin: User name: “admin” or leave blank. Password: “admin“, “password” or leave blank
  • Edimax: User name: “admin“, “root” or blank. Password: “admin“, “password“, “1234“, “epicrouter“, “root“, “conexant
  • Siemens: User name: “admin” or leave blank. Password: “admin“, “user” or leave blank
  • SMC: User name: “admin“, “smc“, “smcadmin“, “cusadmin” or blank. Password: “smcadmin“, “root“, “barricade“, “password“, “highspeed” or leave blank

Some Internet providers provide routers and other network devices for households as well as features that allow administrators to enter a “friendly” name in the web browser instead of the IP address. For example, Belkin users can enter “” http://routers “instead.

Troubleshoot the router admin login

If the browser responds with an error like “This webpage is not available”, the router will be offline (disconnected from the network) or unable to respond due to technical problems. Here are some actions you can take to reset your connection to your router:

    • Make sure that the ethernet cable connects your router to your modem in a good and secure connection. For wireless routers, also check the cable connecting your device to the router itself.
    • Check the router’s LED to ensure that the appropriate indicator light is on. For example, most routers display their connection status via an Internet LED, a wireless LED and a numbered LED to determine which port your computer is connected to. Compare them with the manufacturer’s manual to ensure that all connections are valid.
    • Reset your connection:
      1. First, turn off the Internet modem and unplug its cable from the router.
      2. Next, turn off the router and the computer or other related device.
      3. Then re-enable the router and then the computer and try connecting to the router. At this point, the router has the opportunity to reset its IP as well as the IP of the device.
      4. Finally, reconnect the router to the modem.

If you are still having problems with the router and can not connect to the administration console, contact your router manufacturer.

Limit use of this address

Address is an IPv4 Private Network Address, which means it can not be used to connect to a router from outside the home network. (The public IP address of the router must be used instead.)

To avoid IP address conflicts, only one device at a time on the local area network can use For example, a home network with two routers running simultaneously must be set up with different addresses.

Home users can also be mistaken to think that a router needs to use the IP address when it is configured to use a different address. To confirm the address the local router is using, the administrator can look up the default gateway that is located on any device currently connected to that router.

If you are using a Windows PC, you can quickly access your router’s IP address (called “default gateway”) using the ipconfig command as follows:

  1. Open Command Prompt.
  2. Enter ipconfig to display the list of all connections of the computer. The IP address of the router (assuming the computer is connected to the local area network) is “Default Gateway” in the Local Area Connection section.

Change this address

You can change the router’s address if you want, as long as it is within the allowed range for the Private IP address. Although is a common default address, changing it does not significantly improve the security of your home network.

Routers that do not use the default IP address can be restored to use the default values ​​through hard reset. is a private IP address that can be assigned to any local area network device. It can also be assigned as the default IP address for some router models.

This address can be manually assigned to devices on your local network that are configured to use this address range, such as laptops, smart TVs, phones, desktops, tablets, Chromecast, etc .. and as the default address for the router, is the IP address that is integrated into the device when it is manufactured.

Note: Addresses and are easily confused. The home network uses the 192.168.1.x address (such as rather than the 192.168.100.x address.

How to connect to router

Administrators can log into a router with this IP address by accessing it as a URL. In the web browser, enter the following address:

After accessing the above address, the browser prompts the user to enter the admin username and password.

If you do not know your modem account and password, go there 

Administrators can easily change the router’s IP address from a default or custom number to Some people may choose to change this address with a more memorable address to log into the router.

Note: Most routers do not use as their default IP address, instead using,,, or

Set address as the IP address for the client

Administrators can choose to assign addresses to any device on a local area network, not just to the router. This can be done automatically through DHCP or manually to create a static IP address.

To use DHCP, the router must be configured to have address within the pool of addresses it allocates. If a router starts its DHCP range by address, tens of thousands of addresses in the range with lower numbers such as are not used. Administrators usually specify as the first address in the DHCP range so that not only is used but also addresses such as,, etc. are also used.

By manually assigning a static IP address, the network mask of the router must be set up correctly to support the IP address.

More information on is a separate IPv4 address, which means that you can not connect to a client device or router from outside the home network as with a public IP address.

Its use only relates to local area network (LAN). When using this address, performance or security is no different when using other private network addresses.

Only assign an IP address of to a device. Administrators should not assign this address manually when it belongs to the router’s DHCP address range; otherwise, an IP address conflict will occur because the router can automatically assign the address to a device though. Another device has used it as a static address. Admin router IP address is a private IP address, default for some types of broadband routers in the home. It is also often assigned to individual devices in a home network when a router has an IP address of As a private IP address, does not have to be unique across the entire Internet, but must be unique in the local area network.

Although this IP address is set by default for some routers, any router or computer on the local network can be set to use

How Private IP Addresses Work

No special meaning or value for individual IP addresses – they are simply designated “private” by the Internet Assigned Numbers Authority (IANA), a global organization that manages IP addresses. Private IP addresses are only used on private networks and can not be accessed from the internet, but can only be accessed from devices on private networks. This is why modem and router can easily operate by using the same private IP address. To access the router from the Internet, you must use the public IP address of the router.

The address range reserved by IANA for use on private networks is in the range of 10.0.x.x, 172.16.x.x, and 192.168.x.x.

Use to connect to a router

If the router is using on the local network, you can log into the administration console by entering its IP address in the URL address bar of the web browser:

The router then prompts for the username and password for the administrator. All routers are configured with the manufacturer’s default username and password. The most common default username is “Admin“, “1234” or no username. Similarly, the most common passwords are “admin“, “1234” or nothing, the same as the username. The default username/password is usually written on the back of the router.

It’s not usually necessary to access the router’s administration interface, but it can be useful if you’re having trouble connecting.

Why did become popular?

Manufacturers of routers and access points must use IP addresses in a private area. Initially, broadband router manufacturers such as Linksys and Netgear chose the default of 192.168.1.x. Although this technical range starts at, most people would think that a sequence of numbers would start with 1 instead of zero, so would be the best choice for the beginning of a family network address range.

With this router assigned the first address, it assigns the address to each device on the network. Therefore, IP becomes the most common starting point.

Networked devices do not achieve better performance or better security from IP addresses, whether it is, or any other private address.

Assigns to a device

Most networks assign private IP addresses automatically using DHCP. This means that the device’s IP address can be changed or reassigned to another device. Trying to assign this address manually (a process known as “fixed” or “static” address assignment) may also be performed, but may cause a connection failure if the network router is not configured. corresponding configuration.

Here’s how it works:

  • Each local router using DHCP is configured with a series of addresses that it can allocate to clients.
  • On the home router whose default address is, the default address for the guest address is to Most routers will assign IP addresses to network devices starting at the beginning of this range, so you rarely see IP addresses on your network outside of the scope.
  • A router generally will not check that (or any other address in this range) has been assigned to a client manually before automatically assigning it to a client. This can cause IP address conflicts where two devices on the same local network try to use the same IP address.
  • IP address conflicts will disrupt the network interface of both devices. For these reasons, you should allow your router to control the assignment of IP addresses in the home network.

Use to connect to your router. If this IP address does not work, your router will use a different router, which you can find with our IP Search Guide for Windows, Android, Mac OS, Linux, and iOS.

IP address is the specific address specified by some router manufacturers in their device’s hardware settings as the default IP address. It allows users to access the internal settings of the router or modem.

This private IP address (as well as the well-known IPs and is used in most networks and small businesses because ISPs typically assign a unique IP address to a device that is used to Connect to the Internet, If many of your devices need Internet access, a network address translation (NAT) port is used to connect to the Internet. is classified under the IP Class C classification (as defined by IANA RFC 1918).

Find IP routers

If your router’s IP address is different from, you will need to refer to the appropriate router manual for standard logins and processing instructions.

Once you know your router’s default password and can connect to the administration console, you should change your router’s default password and use a secure password. It’s not easy to remember complex passwords deviated from the standard, but a password manager like KeePassX (or similar) can be very useful. Do not change the default password of the router will cause large security holes in your network. It can be particularly vulnerable if you are using port forwarding and your network is accessible over the Internet.

Some brands use IP address as:

  • Westell DSL Modem (ONLY INCLUDED)
  • Some Linksys Routers / Modems
  • 3Com router / modem
  • Hundreds of routers / modems
  • Netopia / Cayman Gateways

Search for a standard router password for: …

The default username and password

The most common default username and password for routers using is the default address of admin/(blank) and admin/admin.

For Netopia routers, the administrator/administrator or administrator/1234 should be used as the default user and password.

See our default router password page for a list of routers password extensions.

What is IP address?

IP (Internet Protocol) is the number format for a network device, devices that use IP addresses to communicate with each other over IP-based networks such as the Internet.

Most IP addresses look like this: or, this is the IPv4 address. Some other IP addresses are: 2001: 4860: 4860 :: 8844, this is the IPv6 address.

What is the IP address used for?

An IP address provides identification for a network device, similar to a home or business address. Devices on the network have different IP addresses.

For example, if you send a package to a friend in another country, you need to know the exact address, not just the name and expect the package to reach your friends. You need to write a specific address by looking in the phone book. The process of sending data over the network is similar to the example above. However, instead of using the telephone directory to find their address, the computer will use the DNS server to look up a hostname to find its IP address.

For example, when entering a web page into a browser, like blogtip.org, the request to load this page is sent to the DNS server looking for the server name (blogtip.org) to find its corresponding IP address. Without an IP address attached, the computer will not have a “clue” to the search.

Types of IP addresses

Even if you have heard of previous IP addresses, many people do not know how many IP address types are there. Although all IP addresses are made up of numbers or letters, not all IP addresses are used for the same purpose.

IP address type: private IP address, public IP address, static IP address and dynamic IP address. Each type of IP address can be an IPv4 address or an IPv6 address.

Public IP addresses are used “outside” the network and are assigned by the ISP. This is the primary address that home or business networks use to communicate with other networked devices around the world (ie, the Internet). It provides access to in-house appliances, for example, to reach ISPs, allowing them to perform tasks such as visiting websites and communicating directly with other users’ computers.

Both private IP addresses and public IP addresses can be dynamic or static IP addresses. An IP address assigned by a DHCP server is a dynamic IP address. If the device does not turn on or does not support DHCP then the IP address must be manually assigned, in which case the IP address is called a static IP address.

How to find IP addresses

Different devices and operating systems require different operations to find the IP address.

Find the public IP address

There are many ways to find public IP addresses on your router, such as using ipchicken.com, whatsmyip.org or WhatIsMyIPAddress.com. These sites work on all networked devices that support web browsers such as smartphones, iPods, laptops, desktops, tablets, etc.

Find your own IP address

Other than finding a public IP address, finding a specific IP address of a particular access device is not simple.

In Windows, users can find the IP address of the device through the Command Prompt, using the ipconfig command. In Linux, use the terminal window and enter the command enter hostname -I (i in capital letters), ifconfig or ip show addr. For Mac OS X, use the ifconfig command to find the local IP address.

Find your private IP address on iPhone, iPad, and iPod touch devices by visiting the Wi-Fi menu in Settings, pressing the small “i” button next to the connected network. Depending on whether the IP address is assigned by DHCP or manually entered, you will see the DHCP or Static tab.

For Android users, go to Settings> Wireless Controls> Wi-Fi settings, then touch the network in the new window to display network information including your private IP address.

IP version (IPv4 and IPv6)

There are two IP versions: IPv4 and IPv6. IPv4 is the old protocol and IPv6 is the upgraded version. The reason that IPv6 is replacing IPv4 is that it can provide a large number of IP addresses over IPv4.

As more devices are connected to the Internet, a separate address for each device is needed. IPv4 addresses are built to provide over 4 billion unique IP addresses (232). Although this is a very large number of addresses, it is not enough for all the devices users use on the Internet.

There are billions of people on earth, even when people own only one device and use it to access the Internet, IPv4 is not enough to provide an IP address for all. On the other hand, IPv6 supports 340 trillion trillion, trillion addresses (2128). That’s 340 numbers with 12 zeros. This means that people on Earth can connect billions of devices to the Internet.

In addition to providing multiple IP addresses over IPv4, IPv6 does not cause IP address conflicts caused by individual addresses, automatic configuration, no need to use NAT (Network Address Translation) technology, efficient routing and easier management.

IPv4 displays addresses in the form of 32-bit long strings written in decimal format, such as or Since there are trillions of IPv6 addresses, they are written in hexadecimal as 3ffe: 1900: 4545: 3: 200: f8ff: fe21: 67cf.

Static or dynamic IP address

If using a cable or using a DSL service, most IP addresses that you use are dynamic IP addresses. However, some ISPs also assign static IP addresses. To check that the IP address you are using is a dynamic IP address or a static IP address, you can refer to the following article in Network Administration.

1. Is your IP address static or dynamic?

The easiest and easiest way to check your IP address is to use static or dynamic links to your Internet service provider to get answers.

However, if you still want to know or to confirm the information, you can apply below to see if your IP address is static or dynamic.

2. Check IP Addresses on Windows 8 and Windows 10

If you are using Windows 8 and Windows 10, and you want to check whether the IP address you are connecting is static or dynamic IP, follow the steps below:

  1. Right-click the Start button in the bottom left corner of the screen.
  2. Next, click on Command Prompt.
  3. On the Command Prompt window, enter the following command and press Enter:   ipconfig /all 
  4. At the Command Prompt window, locate the DHCP Enabled item and look at the value next to the item.
  5. If the value of DHCP enabled is set to Yes, your IP address is static. And if the DHCP enabled value is set to No, your IP address is the dynamic IP address.

3. Check your IP address on Windows 7

To check whether the IP address on your Windows 7 computer is static or dynamic, follow these steps:

  1. Click the Start button.
  2. On the Search box, type  cmd  and press Enter.
  3. From the list of search results, click Command Prompt.
  4. On the Command Prompt window, enter the following command and press Enter:  ipconfig /all 
  5. At the Command Prompt window, locate the DHCP Enabled item and look at the value next to the item.
  6. If the value of DHCP enabled is set to Yes, your IP address is static. And if the DHCP enabled value is set to No, your IP address is the dynamic IP address. is the second most commonly used IP address to access the modem/router configuration page (in most cases, the default IP address is

If you need to access your router/modem’s configuration page, just click this link or copy/paste it into your browser’s address bar:

If you just purchased your modem/router, you must enter the username and password specified in the device’s guide to your credentials. Usually the username is admin and the password is admin (the first thing to do is change the password to prevent the neighbor from connecting and changing the profile).

Want to understand more about ip addresses and find out why you use

Sit comfortably: the explanation is simple but adequate. The ip address is a code that identifies an entity in the network: it may be your laptop, your iPad, but also a website. In fact, each site is associated with a unique IP address identifying it in the Internet world. When you enter the google address on your computer, the two information will come to your modem; The ip address of the person who requested to view your site (your computer) and the site you want to visit (google).

There are two types of ip addresses: public and private.

Public addresses are visible to anyone who is connected to the internet and for this reason they must be unique (if the same ip is used by two different sites, you may never see one. two sites or see a different site at each refresh).

Private addresses are used in local lanes and are not spread to the internet; In this way, all the PCs you have at home can all have their own ip without having to use a scarce public ip (and thus be paid).

There are about 17 million private IPs that can be used but by convention, we almost always use two ips to access the router configuration page: and

I entered 192.168.O.1 but it does not work!

NOTE: The IP address is only NUMERIC

Sometimes rush writing happens to hit the letter O instead of zero; good test. It happened to me more than once to reset the modem just to realize that I had written the wrong address.

Once you reach the configuration page of your modem, you can change the basic settings to get the most out of your new router. Remember to check out our guide for details!
