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

Ethernet doesn't have a valid IP configuration Error1

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!

    1. 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: 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 🙂

        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.

    Tried all of the above, but still have a problem with the ethernet landline (WiFi works fine and is pinch-hitting for the internet connection for now). System was working fine up until a few days ago when I was attempting to used Clonezilla to backup the system onto an external disk. No joy trying to do that, since the Windows 10 disk is segmented into six partitions, versus the old Windows 7 system it replaces, which was all nicely loaded into a single partition. After a couple of abortive attempts, the Ethernet connection stopped working. Tried a couple of new cables, different ports on the cable modem, no luck. Tried several techniques, including everything on this page, to resolve the problem, but no luck. Suggestions?

    Hi, ive tried each one of the steps, none seems to work,
    also when i am trying to run ipconfig /renew , i see this error:
    unable to connect to your DHCP server.
    i’ve checked the services too, DHCP is running.
    even after restarting the services the problem still persists.

    Hi there I have tried the first 4 so far and no luck. However I wanted to note that I am using a tp-link that sends the internet data through the power lines around the house. I have to reset the to link every time I turn off my computer. Problem is the other side is my landlords so it’s hard to access. Do you have any experience using this device? It seems that the internet is being sent through the device fine. But my computer is having issues with it.

  13. Thank you for help getting win10 network running!

    I get the error you describe but only on “ethernet3”. Ethernet 1&2 work fine. I am a little afraid to apply your solution, afraid that it will affect ethernet 1&2. Should I go ahead and apply the first fix?

    Thanks for your help
