How To Fix Wi-Fi Doesn’t Have A Valid IP Configuration Error

Before performing any of the recommended troubleshooting steps listed below it’s best to restart your computer first. This action refreshes the operating system and remove any corrupt temporary data that could be causing the problem.

Release And Renew Your IP Address

One of the first troubleshooting steps that you should do in this case is to release and renew the IP address of your computer. 

  • Press Windows key once
  • Type cmd in the Start Search box.
  • Right click on the Command Prompt and click Run as administrator…
  • Type ipconfig /release and press Enter
  • Type ipconfig /renew and press Enter
  • Type Exit and press Enter

Check if the Wi-Fi doesn’t have a valid IP configuration error still occurs.

Reset TCP/IP

If the WiFi adapter of your computer sees the available network but it won’t accept tcp/ip address then attempting to reset winsock and ip stack may resolve the problem.

  • Press Windows key once
  • Type cmd in the Start Search box
  • Right click on the Command Prompt and click Run as administrator…
  • Type netsh winsock reset and press Enter.
  • Type netsh int ip reset and press Enter.
  • Type ipconfig /release and press Enter.
  • Type ipconfig /renew and press Enter.
  • Type ipconfig /flushdns and press Enter.
  • Restart the computer.

Check if the Wi-Fi doesn’t have a valid IP configuration error still occurs.

Perform a clean reboot

There might be a process from a software you installed running on your computer that is causing the problem. To check if this is the culprit, you will have to do a clean reboot.

  • Hold Windows key and press R
  • Type msconfig and press Enter
  • Select Services tab
  • Check Hide All Microsoft Services
  • Click Disable all

  • Select the first item presented in the Task Manager and click Disable. Repeat this step for all the items in the Task Manager
  • Close the Task Manager window
  • Click Ok in the Startup Tab
  • Restart your computer

If the problem persists then you don’t have a software conflict and the problem lies elsewhere. If the problem does not occur then you can now attempt to find the offending program or service. The best way to do so is  re-enable half of the services then check if the issue occurs. Do this for the other half as well in case the issue does not occur. Repeat this process until you can pinpoint the culprit. 

To start your computer normally

  • Right-click the Start button.
  • Click Search.
  • Type msconfig and hit Enter on your keyboard.
  • Click Services.
  • Click the checkbox next to Hide all Microsoft services.

  • Click Startup.
  • Click Open Task Manager.
  • Click a startup program(s).
  • Click Enable.
  • Click the X to close Task Manager.
  • Click OK in the System Configuration window.
  • Click Restart.
