WiFi technology1 is used by billions worldwide. However, some people may encounter issues such as the “WiFi doesn’t have a valid IP configuration” error on Windows 10 or 11. This error occurs when your PC fails to secure a functioning IP (Internet Protocol) address over WiFi. You may also come across a similar IP-related error while using Ethernet (cable internet) not just Wifi. 
By the way, if your ethernet is acting up — this guide might help you!

Why is Windows Giving a “WiFi doesn’t have a valid IP configuration” Error?

Suppose you’re having trouble connecting to WiFi on your Windows 10 computer. In that case, you may see an error message that says the IP Address configuration on the router doesn’t match the IP Address your WiFi network adapter is using. 

It may occur after a Windows update or if network changes have not been pushed to the network adapter. There are several possible causes for this error in Windows 10/11. 

The following are some of the most common causes:

  • Unidentified network: This issue can occur when fixing your WiFi connection using the built-in troubleshooter. Network identification may have been wrong, causing your system to disconnect.
  • No Internet connection: WiFi configuration errors may occur if you don’t have an active internet connection.
  • Issues with drivers: Drivers are essential for your computer to function correctly. If your drivers need to be updated, updated, corrupted, or damaged, several problems can arise.
  • Third-party antivirus: Some users report that third-party antivirus software installed on their computers causes WiFi configuration errors. You can disable or uninstall this software.
  • Other Windows 10 or 11 issues: Your case may be unique, and the error isn’t listed here.

In this case, we recommend performing the troubleshooting methods below and seeing if you have any luck restoring your system.

TL;DR – Quick Ways You Can Try Now to Fix The Error

Before we dive into the fixes, try these quick tricks:

  • Ensure that your PC’s security type matches your router’s. Your security type can cause IP configuration failures. To do this, open your router’s settings page and check security settings.
  • While in the router settings, ensure the WiFi PMF (Protected Management Frames)2 setting is disabled. This setting is unavailable on every router, but disabling it should work for those where you find the setting.
