When we encounter this error, we can not immediately determine whether the error is due to network or error by the website, but by following the steps as guide below you will succeed and access the normal network.

Error due to network

This is a rare occurrence, not a failure. Because our network has a problem, too slow to send and receive requests from the server side of the website. Error ERR_CONNECTION_TIMED_OUT due to a faulty network that will appear when we visit any website, including and Facebook.

How to fix network inaccessibility: Turn off the modem with the power button or directly pull the power cord. After about 30 seconds, open / reconnect the power cord as before. Wait 30 seconds for the modem to receive the network, maybe longer. After that time, visit Google or Facebook to check.

If you still can not access any of the websites, please contact the operator to get back to the testing house.

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

Fix ERR_CONNECTION_RESET error on Chrome browser

If you encounter ERR_CONNECTION_RESET in Chrome when browsing a few web pages, this means that the browser can not establish a stable connection or absolutely do not have a website you want to open. While some sites open well, others show this error. Connection reset means that when the data is received by the peer computer, in this case, you can not handle it. This post will show you how to fix error 101, ERR CONNECTION RESET in Google Chrome browser on Windows 10/8/7.


When you see this error message, you’ll also see the following message:

This website is not available, The connection to was interrupted, Error 101 (net:: ERR_CONNECTION_RESET): The Connection was reset

Here are our suggestions on how you can fix it. Make sure to reload the page after each change you make to find what’s right for you. As usual, I will split the troubleshooting steps into two. First for PC and second for Chrome.

Troubleshoot PC network problems

1] Check your network cable, restart the router and reconnect

Basic tips, but sometimes the cause of the problem. Make sure you check that your cable is properly connected to your computer or router. If you connect via WiFi, be sure to restart your router once. Finally, you choose to forget the WiFi you have connected and then reconnect.

2] Delete Proxy:

  • Hit Windows Key + R and enter “inetcpl.cpl” and hit enter to open Internet Properties.
  • Next, go to the Connections tab and select LAN settings.
  • Uncheck Use a proxy server for your LAN and make sure to select “Automatically detect settings”.
  • Click Ok then Apply and restart your PC.

If you are using a third-party proxy service, please disable it and try again.

3] Delete DNS and reset TCP/IP

Sometimes the site does not work because the DNS in your computer still remembers the old IP. So be sure to Flush DNS, and Reset TCP / IP.

To FlushDNS, run the following cmd command:

ipconfig /flushdns

To reset TCP / IP, run the following command on CMD:

netsh int ip reset resettcpip.txt

4] Increase MTU (Maximum Transmission Unit)

Speed ​​up internet also helps. Here, it means you can increase the MTU (Maximum Transmission Unit), RWIN (TCP Window Receive) parameters.

  • Go to Settings> Network & Internet> Ethernet
  • Note Active Wireless / Wired Network Connection, such as Ethernet
  • Open cmd with administrator privileges.
  • Type the following command in CMD and press Enter:
netsh interface IPv4 set subinterface “Ethernet 4” mtu=1472 store=persitent

5] Disable the AppEx Network Accelerator feature

AppEx Networks Accelerator is known to slow down network connections. Many people report that it slows down the network speed by 70% to 80%. It’s best to disable this feature.

  • Go to Settings> Network & Internet> Ethernet> Change adapter options.
  • Right-click your network and select properties.
  • Find AppEx Networks Accelerator and uncheck it.
  • Save and exit to see if the problem is resolved.

6] Delete WLAN configuration (When connected to WIFI network)

When you connect to many networks, all of them are stored on your PC. Next time you reconnect to that network, it will automatically connect. It is possible that one of the networks has been changed, and it is not connected properly, or it may be disconnected from the network. It is best to delete all WLAN profiles and start new ones.

7] Reinstall the Network Adapter Drivers

If deleting WLAN configuration does not work, it is possible that the network drivers are corrupted. You will need to re-install the network adapters and reinstall the network drivers for best results. Windows Update will immediately download the driver and install the new driver.

8] Disable WiFi Miniport

Hit Windows Key + X and select Command Prompt (Admin).

Type the following command in cmd and press Enter after each command:

netsh wlan stop hostednetwork
netsh wlan set hostednetwork mode=disallow

Exit the command prompt then press Windows Key + R to open the Run dialog box and type: ncpa.cpl

Press Enter to open Network Connections and find Microsoft Virtual Wifi Miniport and right-click and select Disable.

Fix Chrome issues

I would suggest a few things here. This will ensure that if there are any malicious software or installations that are restricting the network, it will be handled.

1] Start your browser in Safe Mode

Just like Windows Safety Mode, Chrome also has Safety Mode where Run Mode does not have any user settings and extensions. You can run it manually or just use the keyboard shortcut to launch Chrome in Safe Mode and see if your issue is resolved.

2] Run the Chrome Cleanup Tool

Run the Chrome browser’s built-in cleanup and malware scanner. It helps you remove unwanted ads, pop-ups and malware, Extraordinary Startup pages, toolbars, and anything else that destroys the experience by hitting the webpage by overloading. pages with memory requirements.

Type in the address bar:


3] Reset Chrome settings

This option is similar to Reset Windows 10. When you reset Chrome, it will return to the default settings during the new installation. It will disable all extensions, extensions and themes. In addition, the content settings will be reset. Cookies, cache, and site data will be deleted.

Let us know which solution works for you to resolve the ERR_CONNECTION_RESET error in Chrome.


How to secure your home Wi-Fi network

If your Wi-Fi network is unusually slow, there are a number of possible causes for this, but it’s possible someone is stealing your Wi-Fi. While no security measure is perfect, there are some simple ways you can do to improve Wi-Fi security and make it harder for strangers to access it.

1. Check if there are strange devices accessing your home Wi-Fi

You can scan all devices using your Wi-Fi network with the software. The list will display the names and icons of those devices that will be displayed and you can easily identify the devices. We’re using our Wi-Fi network. In addition, some applications provide full IP address, time and storage usage of those devices not invited.

You can download Wi-Fi scanning software on all popular operating systems like this one:

Android: You download ezNetScaner software at this link.

iOS: You download the IP Network Scanner software at this link.

Windows: You download the Wireless Network Watcher software at this link.

MacOS: You download the AirRadar software at this link.

2. Change the Network Name (SSID)

The hacker can know the default username and password on the router (not the Wi-Fi password) and then access and modify some information such as Passwork Wi-Fi for unauthorized use.

You can change the manufacturer’s default network name simply by following these instructions:

Step 1: Access Wi-Fi and type, or (depending on Wi-Fi device) into your browser, then enter your username and password to access. go to the router configuration page.

If you are not sure, you can view this information on the back of the device or call the operator’s network operator for assistance. And note that most of the next security customization of the article is through this step 1.

Step 2: Access the ‘ Administrator’  or ‘ Admin’ section . Note, the name and location of the options may vary depending on the type of device you are using.

Step 3: You proceed to change your router login and password.

Change the administrator user password to something slightly unpredictable. Passwords must be a passphrase, and you should also use capital letters, numbers, and some special characters as passwords.

3. Change Wi-Fi password

Even if your Wi-Fi password is extremely strong, you’ll need to change it if you see the first signs of a Wi-Fi password being stolen. Like any password, it’s a good idea to make frequent changes to enhance your security with new phrases every few months.

Typically, the option to change Wi-Fi passwords is usually in the ‘Wireless Security’ or ‘WPA PreSharedKey’ section .

4. Turn on the firewall

Not all routers have a built-in firewall, but if your router has one, turn it on. Firewalls can act as your first line of defense because they are specifically designed to manage and filter traffic out of your network and can automatically block suspicious access through Ports are not licensed for use.

5. Turn off WPS

WPS stands for Wifi Protected Setup, which is a technology that is almost universally available on all recently released wireless routers, making it simple to connect devices to Wi-Fi networks. Although WPS theory works very well in some cases of public Wi-Fi, the actual Wi-Fi is not as good as it really is. WPS can cause some security holes.

It is best to disable this technology by logging in to your modem or router, then go to ‘Wireless’ > ‘Wireless Basic Settings’ > ‘Wi-Fi Protected Setup’ , select Disabled in the WPS section. save.

6. Change security mode

All you need to do is to choose a secure option and get the most out of your connection so it’s hard for anyone else to steal your Wi-Fi password.

The user should change the security mode to WPA2 / WPA Mixed Mode (if available) or Persona WPA2 , WPA / WPA2 Enterprise , restrict WEP usage (a long mode and many vulnerable holes) or Open, finally hit Save Changes to save.

7. Update your router software regularly

The router also uses an operating system. However, it does not automatically update the security updates that you need to manually update it. Some routers can download firmware updates from the Internet, some of which have to be downloaded manually and then downloaded to the router from your computer.

Updates often include important security fixes. If you do not update, the attackers will take advantage of these security flaws to access your network. You do not need to do this often, just check the updated few months once the gain is.

8. Turn off and open Wi-Fi automatically

If you are away, you can turn off Wi-Fi at this time or when you go to sleep. This helps limit the impact on the outside of the router and if anyone is already using your Wi-Fi it will be very frustrating and will not use it anymore because it is disconnected frequently.

You can also turn off the automatic power off of your modem for hours and days on weekdays by going to “Automatic Wifi Shutdown” , set the day off, and then tap “Apply”.

Reboot vs Reset: what is the different?

What does Reboot mean? Reset what computer, router, phone, etc. It seems silly to distinguish them from each other but they are really different!

The important reason to know the difference between rebooting and resetting is because they do two very different things, although they sound the same. You need to know when to do something.

All this sounds confusing, but read on to find out what these terms are and to know exactly what to do to fix the problem or get technical support.

Rebooting is turning off something and then turning it back on

Restart, power cycles and soft settings all have the same meaning. If you are asked to “restart your computer,” “restart your phone,” “restart the router,” or “reset your laptop,” you are required to turn off the device. No longer receive power from the power source or battery and then turn it back on.

Rebooting is a common task that you can perform on all types of devices if they do not work as they should. You can reboot your router, modem, laptop, tablet, smart device, phone, desktop, etc.

Technically, restarting a device means repeating the power state cycle. When you switch off the device, the device will not receive power. When the device is turned on, it will again receive power. Rebooting is the only step involved in both shutting down and then powering on something.

Note: There are also terms such as hard / cold boot and soft / warm boot. When most devices (such as computers) are powered off, all software programs are disabled during this process. This includes everything loaded into memory, like any video you’re playing, the site you open, the document you’re editing, and so on. Once the device is turned on, those applications and files must be reopened.

However, while running software is turned off with the power, both the software and the program you opened are deleted. The applications simply turn off when the power goes out. When power is provided again, you can open software programs, games, or files, etc.

Note: Putting your computer into hibernation and then turning it off, is not the same as shutting down the computer normally. This is because the memory contents are not deleted but instead are written to the hard drive and then restored the next time you restart the computer.

Unplugging the power cord, removing the battery, and using the software buttons are some of the ways you can reboot the device, but not a good way to do it.

Reset means delete and restore

The definition of “reset” is something that can be confused with words such as “reboot”, or “soft reset” because they are sometimes used interchangeably, although there are two completely different meanings.

The easiest way to distinguish is to understand reset like deleting. To reset the device, reset the device to the same state as when purchased for the first time, commonly known as restore or factory reset. Literally, it means deleting and reinstalling the system, since the only way to actually reset is to completely erase the current software.

For example: You forgot your password for your router. If you only restart the router, you will be in this situation when it is re-enabled: you do not know the password and there is no way to login.

However, if you have reset the router, the original software that it has moved will replace the software running on it just before the reset. This means that any customizations you have made since you purchased it, such as creating a new (forgotten) password or Wi-Fi network, will be deleted as new software (original) has been instead of, replace. Assuming you have actually done this, the original router password will be restored and you can log in using the default router password.

Because it will erase all settings, resetting your computer or other device should be limited unless you really need it. For example: You can reser your PC to reinstall Windows from scratch or reset your iPhone to delete all your settings and applications.

Note: Remember that all of the following are references to software removal: reset, hard reset, factory reset, master reset, and restore.

Why should distinguish between reset and reboot?

This difference has been mentioned above, but it is important to understand the consequences of confusing these two common terms.

For example, if you are asked to “reset your computer after you install the program”, what you are being instructed to do is delete all the software on your computer just because you have installed a new program. Oh? No, this is clearly a mistake and the exact requirement is to restart the computer after installation.

Similarly, simply rebooting your smartphone before you sell it to someone is definitely not a wise decision. Restarting the device will just turn it off and on again, rather than actually resetting / restoring the software as you really would like, in this case having to reset the device, ie deleting all custom applications. and delete any personal information associated with it.

If you still have difficulty catching the differences, keep in mind: restart is a reboot and reset is a new system setup.

Saving Mobile Data: 6 wonderful tips on iPhone

For many people who regularly use 3g/4g, running out of high-speed traffic or running out of the internet’s bandwidth is unavoidable.

1: Turn off Wifi support.

You go to Settings => Cellular (= Cellular) => down and down. Wifi support (wi-fi assist).

This is the feature that automatically turns on the data network when the wifi network is weak. But, you should turn off this feature, to avoid the mistaken case is still using wifi without knowing the machine has manually switched to 3g.

2: Disable applications that use a lot of data.

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)

Windows Has Detected An IP Address Conflict – How to fix

Are you facing a Windows Has Detected An IP Address Conflict error when connecting your computer, laptop to a wireless network, or through an Ethernet cable? Here are 3 ways to fix Windows Has Detected An IP Address Conflict.

When connecting your computer, smartphone, or any other device to your local network, all of these devices will receive a unique IP address. The main purpose of using this IP address is to distinguish each device on the same network as well as to communicate with other networks. You can also call this an internal IP address (IP stands for Internet Protocol).

For example, when you connect a laptop, and a smartphone on the same wireless network, then each device will have its own IP address, and that’s the only IP address.

However, sometimes wrong configuration or wrong IP address settings can cause IP address conflicts. If you are using a Windows computer, the screen will display an error message of the form: Windows Has Detected An IP Address Conflict.


It is possible to understand the error occurred because two devices use the same IP address on the same local network. As mentioned above, each device must have a unique IP address in order to function properly. Otherwise, the device will not be able to communicate with other devices and will not be able to access the Internet and be listed as non-connected devices.

Here are some tips for fixing Windows Has Detected An IP Address Conflict.

Reboot Your Modem Or Wifi Router

After your modem or Wifi Router has booted up, try connecting to your computer and check whether Windows has detected an IP address conflict.

Reset IP Configuration Through Command Prompt

If after rebooting the modem or Wifi Router that Windows has detected an IP address conflict is still occurring, it is possible that the problem is caused by your computer. So the solution in this case is to force Windows to require a new DHCP server (modem / router) to provide a new IP address. To do this you will have to reset all IP address configuration as well as release and renew an IP address.

First press the Windows + X key combination and press A and select Yes to open the Command Prompt under Admin.

Next enter each of the following commands one by one in the Command Prompt window and press Enter:

netsh int ip reset c:\reset-log.txt

ipconfig /release

ipconfig /renew

After you have completed the above commands, restart your computer and check whether Windows has detected an IP address conflict.

Set Up Your IP Address on Your Windows Computer Manually

If you have applied the above two ways and still can not fix Windows has detected an IP address conflict, you can apply static IP address setting on your Windows computer manually, to set the static IP address, Locate and right-click on the network icon in the bottom right corner of the taskbar, select the Open Network and Sharing Center option.

On the Network and Sharing Center window, select the network connection you are using (and also the network connection that is experiencing the problem).

Next select Properties.

Double-click the Internet Protocol Version 4 (TCP / IPv4) option.

The next step is to configure a static IP address according to your modem or router information.

– IP address: This is the static IP address of the computer you want to specify, such as

– Subnet mask: The subnet mask is usually

– Default gateway: This is the IP address of the router, this address is usually

Note: If your modem and router’s IP address is different, such as, the static IP address must also be set to that address, such as Otherwise your computer can not connect to the network.

– Prefered DNS server:

– Alternative DNS server:

You can also use 3rd party DNS server applications.

Finally click OK and restart your computer to apply the changes.

In the above instructions, has instructed you 3 ways to fix Windows has detected an IP address conflict on the Windows computer. Hope these tips can help you fix the problem.

Miracast Windows 10: Guide to show from Smartphone to PC

With technology evolving, you can now connect from one device to another without having to move too much. Especially with Miracast, video presentation from smartphone to PC is quite simple. Let’s go with to learn how to show media from your Smartphone on Miracast Windows 10.

What is Miracast Windows 10?

Miracast Windows 10 is a wireless display standard available on Windows 8.1 or later, Android 4.2 and later versions of these operating systems. With a Miracast receiver plugged into a TV or nearby display, users can display the screen on their mobile device right on the TV screen. It works as a wireless HDMI connection and is a groundbreaking solution, so it’s not limited to a brand or ecosystem.

The Miracast is based on Wi-Fi Direct, a technology that allows two devices to provide direct, peer-to-peer Wi-Fi connectivity so they can automatically discover and connect without a wireless router. Miracast connectivity does not rely on your home network and instead creates its own network, allowing data to move freely between paired devices.

Miracast Windows is largely considered a response or an alternative to Apple’s AirPlay. Standard support built into Android smartphones and tablets can wirelessly stream their screen content to compatible Miracast receivers (such as televisions, streaming audio, and set-top boxes). ).

How does the Windows 10 Miracast work?

To find out how the Miracast connection works, let’s start with the technical specifications: Miracast uses H.264 encoder to mirror video at 1080p resolution as well as 5.1 surround sound. It also has a DRM layer so that a mobile device that supports Miracast can display copyright-protected content, such as DVDs and music, from its screen to a Miracast compatible receiver.

Miracast, as we mentioned earlier, is like a wireless HDMI cable. There is no trouble using the cable to connect two devices, Miracast Windows 10 can display anything you see on the mobile screen and copy it in real time on the other display. with higher resolutions with sound. It also does this without a Wi-Fi network connection.

But this app has a huge inconvenience: let’s say you’re watching a movie on your Android device and want to use Miracast Windows 10 to show it to your PC. Miracast will pair both devices, but if your phone is turned off, locked or simply out of battery, the PC screen will turn off. Therefore, battery issues are extremely important when using the Miracast connection technology.

Miracast Windows 10 can also make Android devices lose battery power during slideshows. It’s a rigorous screen-reflection protocol, and therefore different from AirPlay and Chromecast, is smart enough to transmit online without interrupting activities on mobile devices. They allow for a variety of operations so that you can use your mobile device for other purposes while playing on TV.

Presentation from smartphone to PC via Miracast Windows 10

With Windows 10, Screen Mirroring is in Quick Setting in the Action Center. Click on the dialog box at the bottom right of the Taskbar to display the Action Center. Then click Connect near the bottom. If you still do not see this button, then click Expand on the quick setting.

A list of devices with Miracast will appear after this menu. Click on the device name to start the connection.

Depending on the device, you will need to enter a PIN to confirm the connection. After a while, your device will be connected and shown to the second screen.

The Change projection mode option on the Connect Menu in Windows 10 allows you to choose the playback mode. Or you can choose to play it like the original screen, play the extended version, or just play it on the second screen.

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.

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.
