The error “Ethernet doesn’t have a valid IP configuration” is a common problem with your Internet connection. It means that your computer does not have a valid IP address and therefore cannot access the Internet.

Your computer needs a valid IP address before it can communicate with your router and the Internet. Otherwise, you will not be able to access your email, social networks, online streaming services or any other means. This error usually occurs when your network card (NIC) has a problem, is buggy, out of date, or just does not work together.

As annoying as this bug may be, it only needs to be fixed quickly. Here is how to fix this bug and prevent it from happening again.

  • Press Windows + R, enter servies.msc and press OK.
  • Find the service with the name of the DHCP client.

Reboot your router

If you have problems connecting all your devices to the Internet, and your computer reports that “Ethernet does not have a valid IP configuration”, just restart the router. Turn your modem, router and devices off and on again (turn them off and then on again, from wall to hand (modem, router, device).

Otherwise, you may need a different router. If connecting to other routers does not solve the problem, the problem is with your network card. Perform a factory reset of your network card. If this does not help, replace them.

Configure your network adapter settings

Usually your router will automatically detect an IP address using DHCP technology. However, some routers are configured to work with a static IP address system, which requires you to assign your own IP address.

  • Run ncpa.cpl in Win + Run.
  • Right-click the currently selected network adapter and go to the Properties section.
  • Find TCP IPV4 in the current modules and click “Properties”.
  • If the “Get IP address automatically” option is set, try to set your own IP address. If you are on a standard home network, try If you are on a specially configured network, contact your network administrator.
