All computers and routers are provided with IP address to help users access the Internet. Similar to the Wifi Router, an Internet service provider (ISP) provides an IP address for all Wifi routers to support users connecting to the Internet on their service.

However, in some cases, if the Internet Protocol (IP) address is configured incorrectly, it will cause a “WiFi does not have a valid IP configuration” or “Ethernet doesn’t have a valid IP configuration”  or “Wireless network does not have a valid IP configuration“.

There are three main causes for the “WiFi does not have a valid IP configuration” error on your Windows 10 machine: router failure, wrong IP address assignment, and NIC errors.
