How to fix Ethernet doesn’t have a valid IP configuration Error

Ethernet doesn’t have a valid IP configuration error is cause because DHCP is unable to get a valid IP Address from you NIC (Network Interface Card) .

    Thanks for the help! Method 1: ReinstallingTCP/IP settings fixes my IP configuration error each time. Unfortunately, i need to run these commands nearly every other day because the error keeps recurring on my computer. Any idea why this error would continuously recur? Could it be caused by having too many devices in my home connecting to the internet via Wifi? Thanks again!

    • adityafarrad

      Welcome and no it doesn't cause by having too many devices connected to the internet via wifi, well if the problem keeps occurring itself you might wanna check your PC configuration, what you can do is run Malware bytes see this post here: troubleshooter.xyz/fix-servers-certificate-has-been-revoked-in-chrome/ if it still doesn't solve your problem then see if this problem is another laptop or just yours, try all these and get back to me we will definitely solve this problem :)

      • Jacob

        Thanks. I will download and run Malware bytes and see if that helps? is it okay to run Malware bytes with McAfee already running on my computer? The computer that has the problem most frequently is my desktop that is connected via ethernet cable to my ATT Uverse Modem. In most cases, that is the only computer affected. On a few occasions, the WiFi network has lost connectivity as well.

        • adityafarrad

          Yeah it's okay to run malware bytes with McAfee no problem in that, but after using it make sure you uninstall it. Well if you're computer is connected to your PC then there might be an issue of ip configuration see this post here : http://troubleshooter.xyz/fix-ethernet-doesnt-have-a-valid-ip-configuration/ Well if its only on your PC then doing the steps mentioned in the above link and the previous link might help your case.
