Fix: Ethernet doesn't have a valid IP configuration on Windows

The Uninstall / Reinstall network driver worked! Windows 10 HP laptop. Thank you, I had all but given up on getting my computer to work via ethernet!

First metode are solving my problem
Thanks

Trying using these commands one by one in Command Prompt:-

netsh winsock reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

What if u don’t have a router and simply connect with ethernet cord only? (I’m tethering my connection from a cell phone) it worked for line 2 weeks then just stopped, I think it stopped after I connected to a WiFi hotspot, and yes I’ve since disabled my wifi network adapter, but still can’t get ethernet working

Fixed my issue, thank you - my POWERLINE adapters needed to be reset. I held the reset button down for 10 seconds on one, then the other end, then they reconnected themselves and it was fixed.

Did you manage to fix this?

I have had this same problem after the latest Win 10 Pro update. Yesterday my workstation stopped “seeing” my server and today my server cannot see the rest of the network. All was fine until MS updated my version of Win 10 Pro. A few weeks ago I got the invalid IP config message and ended up reinstalling windows and it fixed the problem. I have 4 machines running on my network. One Apple Mac and three windows machines. They were all talking and running until the updates. I am going to reinstall and not let MS update my boxes.

It worked for me

FFS i finally figured my issue out - you have to login to the router via the generic admin login and toggle Powerline ON!! I switched to Sky Fibre and use Powerline Adapters to extend the ethernet connection around the house. The default setting on the router is OFF - even though the ‘technical specialists’ at Sky didn’t know this and just told me to use WiFi that was so slow given the distance of my PC from the router. This worked for me and could work with other ISPs so try doing the above.

OMG. This worked!! I’ve been trying everything every site/youtube channel says, and nothing worked, but this did!! THANK YOU FOREVER for taking the time to write this. At first, I didn’t know what you meant by “wire line adapter” but I found the little hole in the back of my router, stuck a pin in it until it started to reboot, then waited. It didn’t change anything at first, but a few seconds later, that damned yellow triangle was finally gone!! If you want to know if this is your problem, type in cmd in your search bar beside the windows start button, right click and choose run as administrator, type in ipconfig /all and look for the line that says IP4. If it starts with a 169 something instead of 192 something, this is your problem. Thanks again!!!

Why do you want to connect both at the same time? It isn’t recommended.

I hope you can help me. I am able to connect my PC
to wire network but then I loose the wi-fi. Where the problem could be

You can try the wireless adapter, it costs $15 and if it doesn’t work can be returned to Amazon. It may be the adapter incompatiability with the modem? i.e if the modem router is new, and the computer is very old.

I litrally tried every thing.nothing’s working Ugggggh. I’m going nuts.

Drivers should be updated after attempting all the methods in this guide to restore the connection.

Apart from the issue, i do not trust powerline adapters.

That worked for me! Enter: “ipconfig /renew” There must be a space between the g and the /

Thank you for the suggestion.

There is a space before /renew
Uninstalling the network adapter and reinstalling it automatically renews the IP address as well.

Thank you for the suggestion. There is a space before /renew.
