The debate, whether to use Ethernet or Wi-Fi has been raging for years now, with each offering certain benefits over the other. But, neither is completely free of errors. One of the common ones is Ethernet doesn’t have a valid IP configuration in Windows 11.

The error is not that common, but when encountered, users are unable to access the Internet. Which makes it all the more important to effectively troubleshoot it.

But there is another important question to be answered beforehand, i.e, why Ethernet doesn’t have a valid IP configuration in Windows 11? So, let’s walk you through the answer to it and the most effective fixes for the error.

Why Ethernet doesn’t have a valid IP configuration in Windows 11?

Every device connected to a network needs an IP address, which acts as its identity here. And if it’s unable to get one when using a wired connection, you will encounter the Ethernet doesn’t have a valid IP configuration error in Windows 11.

There could be a bunch of reasons why you are encountering the error. While some have to do with the hardware, others could be related to the settings and software aspects. Here’s a list of them all:

  • Improper connections
  • Problems with the router
  • Malfunctioning NIC (Network Interface Card)
  • Outdated or corrupt driver
  • Misconfigured settings

The solution to most of these issues is rather simple and wouldn’t take more than a few minutes to execute. So, follow the methods below in the listed sequence for quick and effective troubleshooting.

What do I do if Ethernet doesn’t have a valid IP configuration in Windows 11?

1. Check the connections

The very first thing you should do when encountering the Ethernet doesn’t have a valid IP configuration error in Windows 11 is to check that the connections are in order. Make sure that the cable is properly plugged in at both ends.

Ethernet cable

Besides, you can remove the cable at both ends, i.e., the computer and the modem/router, blow light air into both the ports, and then firmly replug the cable. Once done, check if the error is fixed and you are able to connect to the Internet.

2. Restart the computer and your modem/router

Apart from the connections, the problem may also lie with the modem/router or could be a glitch in the OS itself. But, the best part is that most of these can easily be eliminated by a simple restart.

To turn off the modem/router, unplug it from the power source. Also, some may have built-in batteries, so make sure to check and remove them as well. Wait for a couple of minutes and then replug it to the power source.

After restarting both the computer and the modem/router, check if the Ethernet doesn’t have a valid IP configuration error in Windows 11 is eliminated.

3. Disable fast startup

  1. Press Windows + S to launch the Search menu, enter Control Panel in the text field, and click on the relevant search result that appears.Control Panel

After making the changes, restart the computer for these to fully come into effect.

Fast startup is a feature in Windows that reduces the time required by OS to load when you turn on this computer. This is achieved by keeping certain drivers and related processes running instead of terminating them at shutdown.

The Device Manager method is one of the simplest ways of updating the network driver, but the update doesn’t always go through since it only scans the system for a newer version.

If the update doesn’t go through, you can check for the latest driver version in Windows Update or manually install it from the manufacturer’s website.

Also, there’s a simpler and more convenient way of updating the drivers, using a third-party app. We recommend DriverFix, a dedicated tool that will scan every source for the latest version, and keep all the installed drivers up-to-date.
