The error message ‘Ethernet doesn’t have a valid IP configuration’ is very common on a Windows Computer. The error takes place when your computer cannot get a valid IP address from your DHCP server.
By the DHCP server, we mean modem, switch, or router. In layman’s term, it is a network connection issue and it can either be hardware or a software fault. Your network connection will get the details of the subnet mask, gateway, or DNS server by default and automatically.
But for some reason, this has stopped on your computer and this is why you are seeing this error.
When you get this error, oftentimes your computer is unable to establish an internet connection or, you might have a limited connection. Slower bandwidth and everything. But this isn’t a permanent problem and if there is a software issue, it can be solved in no time.
In this article, we are going to be providing you with some of the best fixes that are easy to follow and you can try these to solve the problem. Let’s just get started.

Fix 3: Restart Your Router
Another fix for the problem is to just restart your router. A lot of problems can be fixed by just restarting your router. When you restart your router, it gives you a new IP address and refreshes all the configurations.
This resets the router to default and your network issues are basically fixed. You can find the power switch of your router at the back of the device. Simply switch it off and leave it there for some seconds. After this, switch it back on.
You can also remove the plug from the socket and then plug it back again if you can’t find the button. Turn the router on after around 30 seconds of leaving it in the off state.
Fix 4 : Run Network Troubleshooter
Windows 10 has an integrated troubleshooting tool that you can use to fix various adapter issues.
- Just press the Windows + S key and type Network Adapter.
- Now find and fix the problems with your network adapter.
Select the Advanced tab and check Apply Repairs Automatically. Follow it with ‘Run as Administrator’ and then enter your Windows password. Follow the onscreen prompts and select the appropriate responses for the questions. You may see different questions depending on your problem. And if the problems are fixable, the troubleshooter will give you the fixes that can work.
Fix 5 : Reset Winsock
The next fix that you can try is the Windows Socket fix. Windows Socket is a core component of Microsoft Windows and it does the job of handling incoming and outgoing data requests for applications that use the Internet.
In essence, the Winsock program helps to manage your internet connection and the software applications that want to use your internet connection. You can use a few commands to reset Winsock and this will reconfigure your Ethernet IP address.
- Just open the command prompt and run as administrator.
Now, try the commands below, make sure you try each of them in the sequence:
- ipconfig /flushdns
- ipconfig /renew
- nbtstat –R
- nbtstat –RR
- netsh int ip reset c:\resetlog.txt
- netsh winsock reset
When you are done running these commands in the command prompt, you will get a message to restart your computer. So, just restart the system. When you are back on the system, the errors will be fixed and you will be connected to the internet again.
Fix 6: Update the Windows network driver
If the fixes above do not work then the only way you can resolve the issue is by updating the Windows Network Driver. The ‘Ethernet doesn’t have a valid IP configuration’ error can occur when your drivers are not running as they should. You can always reinstall or update your drivers to the latest version. An incompatible, corrupted, or bad driver can cause the problem. For updating the driver, right-click on the start menu and then
- Go to the Device manager option.
- Search for the network adapter and right-click on the ethernet adapter.
- Now select the ‘Update Driver Software’ option.
The next thing you can do is you can either search for an Updated Driver software or you can browse your computer for driver software.
Select the option you want to use and then update the driver. In addition, you can uninstall the driver and reinstall it again as well. Just search for the latest version of the driver that works with your network card and install it. In windows 10, the system will automatically search for the driver and install it for you. But if you are using the earlier versions of windows, you need to search for the drivers manually.
The ‘Ethernet doesn’t have a valid IP configuration’ is a pretty fixable error. You can use the six fixes that we provided you above. All of these fixes are tried and tested so, they will work 90% of the time. If they don’t work then the problem could be because of the hardware.
