In some cases, Troubleshooting may just find issues but not provide fixes. “Ethernet/WiFi doesn’t have a valid IP configuration” is one of those cases.
Fix A. Restart your computer
This is the easiest fix we will give to you. There are no explanations, just restart your computer after receiving the Ethernet/WiFi doesn’t have a valid IP configuration error 😉
Fix B. Renew IP and DNS to get a valid IP
Renew IP and DNS is another effective option to fix wifi with no valid IP configuration on Windows 10.
1. Open Windows home and type “cmd”.
2. Right-click on the app “Command Prompt” and select “Run as administrator”.
3. Run these commands one by one:
Fix C. Reset TCP/IP
Since IP configuration is the problem, resetting TCP/IP is a great option for troubleshooting invalid IP issues on Windows 10.
1. Open Command Prompt using the same instructions in fix B.
2. Run these commands one by one:
netsh winsock reset
netsh int ip reset
Fix D. Set your IP address manually
When you connect to a wifi or ethernet network you’re usually given an IP address. This process is done by DHCP(Dynamic Host Configuration Protocol), but if there’s an issue with its configuration, you’ll get a non-valid IP configuration error.
1. Press Window+X and open “Networks Connections”.
2. Right-click on your wireless or ethernet network and press on “Properties”.
3. Look for “Internet Protocol Version 4 (TCP/IPv4)” and again go for “Properties”
4. Insert manually the IP addresses and the DNS servers.
5. Last but not less, press “OK”.
Fix E. Uninstall your wireless/ethernet adapter driver
Drivers are always a pain in the butt, so the easier option to deal with them is uninstall and reinstall.
1. Press Windows+R and run “devmgmt.msc”.
2. Expand categories and look for your wireless/ethernet adapter on the “Network adapters” category.
3. Right-click on the wireless/ethernet adapter and choose “Uninstall”.
4. Reboot your PC and reinstall the driver.
