Ethernet doesn’t have a valid IP configuration: 8 Fixes

When connected to any network, your computer gets an IP address assigned to it, which helps the network determine where to send data that you’re supposed to receive.

However, if there’s a problem with this IP configuration or assignment, it can cause several problems, and that’s exactly what we’re going to resolve in this article.

Restart your PC and router

Restarting your computer, router, and any other networking equipment that you might be using can go a long way in helping you resolve seemingly random issues, especially when it comes to network issues regarding IP assignments. 


Updating the driver

If restarting the router didn’t help, try manually updating the WiFi driver.

Step 1: Press Windows key + R, type in devmgmt.msc and hit enter.

Now restart your PC, and it should work just fine. 


Check for IP /DNS conflicts

If you can connect to other networks just fine, it could indicate an IP conflict on your router. 

Another way to confirm this is to ping your router’s default address through the command prompt. Type in ping [router IP address] in the command prompt, and if you get a Request timed out error, you’re most probably having an IP conflict issue. Here’s how you can fix this.

Step 1: Press Windows key + I to open the Windows settings.

Now reconnect to your network, and it should connect seamlessly.


Check your DNS settings

If you’re running custom DNS settings on purpose or by mistake, having them set incorrectly can cause internet connectivity issues.

Flushing your DNS settings can set them back to the default values and can resolve such issues. Here’s how.

Step 1: Press Windows key + R, type cmd and hit the Enter key.

Step 2: Type in ipconfig /flushdns and hit enter. This will reset your DNS settings to their defaults.

You can take this a step further and reset files that Windows uses to access the internet using these commands back to back.

netsh winsock reset
netsh int ip reset

If you suspect an issue with your router’s DHCP assignment, use these commands to release your old IP and request a new one. 

ipconfig /release
ipconfig /renew

If that doesn’t work either, you can use the following commands in the order that they’re listed to reset your network stack.

ipconfig/flushdns
nbtstat -R
nbtstat -RR
netsh int ip reset C:\resetlog.txt
netsh winsock reset
