This error usually occurs when your network interface card (NIC) is having a problem, malfunctioning, is outdated, or just won’t play ball. Fortunately, there are several simple solutions available:

  1. Reboot your system
  2. Reset your network adapter
  3. Restart your router
  4. Run the Network Adapter Troubleshooter
  5. Reset the Winsock
  6. Install or update your network adapter driver

1. Reboot your system

The first and easiest way to fix an invalid Ethernet configuration is to reboot your system. A system reboot has the benefit of resetting all your incoming and outgoing connections. While “turning it off and back on” may seem like an outdated option, the number of problems it can solve is phenomenal.

Resetting your network adapter is another way to refresh your IP address configuration.

Resetting your router can fix several internet connection issues, in the same way as restarting your computer. In terms of “Ethernet has no valid IP configuration error”, restarting gives your router a chance to configure a new IP address for your computer.

Your router may have an on/off switch, which you can usually find on the back of the device. You can turn off the power button, leave it for a few seconds, and then turn it back on. If your router doesn’t have a power button, you can unplug it (or unplug it if your outlet doesn’t have a switch).

Remember to leave a few seconds between turning the router off and turning it back on. Those seconds will give the router’s IP configuration a chance to reset, fixing the invalid IP configuration error.

Press Windows key + Xand then select Device Manager from the menu. Select Network adapters to open the list of network drivers for your device. Locate your Ethernet connection driver.
