How to Fix “Ethernet Doesn’t Have a Valid IP Configuration” Error in Windows 11

We believe that using a wired internet connection is much more reliable than a WiFi connection, such as an Ethernet connection. There is no other medium through which the signal must propagate. Separately, when you connect your computer directly to a modem or router, the computer will automatically retrieve all the data and start working on your internet connection.

Ethernet has no valid IP configuration errors because the network interface card (NIC) is incorrect. Windows network problems can be caused by a router failure, NIC failure, or the wrong IP address assigned to your computer.

The most common reason for this error is that the computer cannot get the IP address correctly from a DHCP server such as a modem or router. Whatever the reason, it’s effortless to fix it using some troubleshooting methods. There are several reasons for this type of error on a PC, and it varies from person to person.

We recommend that you follow this article and try all the methods until the problem is resolved. Some of these methods consist of tricky steps, so follow the instructions.
