Sometimes, Windows Troubleshooter fails to fix the problems faced by users and “WiFi doesn’t have a valid IP configuration” is one of those problems. But as usual we have some fixes that will surely get you out of this problem. Have  look at the methods.

Methods to fix WiFi doesn’t have a valid IP configuration

 Method 1: Release & Renew IP Address

Windows and other operating systems store DNS data in the cache, so you can fast access the website you visited before. But if the IP address of the website is changed, you cannot access the website and will get DNS related errors like DNS_PROBE_FINISHED_BAD_CONFIG. To fix this error, you can try to flush the DNS cache and renew IP address.

Follow these steps:

1. Press Windows + R keys to launch the run box.
2. Type cmd and click the OK to open Command Prompt.
3. Type “ipconfig /release”and press the Enter.
4. Then type “ipconfig /flushdns” and press the Enter.
5. Then type “ipconfig /renew” and press the Enter.

   

Method 2: Manually set IP Address

1) Open Control Panel.

2) View by Small icons, select Network and Sharing Center.

3) Click on Change adapter settings in the left pane.
