Fix 'Ethernet doesn’t have a valid IP configuration' in Windows 10/11 2023

If I helped you, like and subscribe :D

f you’ve previously encountered a networking issue that says Ethernet doesn’t have a valid IP configuration, then something is wrong with your Network Interface Card. The NIC is connected to your router or modem via the Ethernet cable. The problem arises if it fails to obtain a valid IP address.

A valid IP address is necessary for a computer to communicate with the router and operate in the web. Once a certain router or NIC becomes faulty or in case of incorrect IP address designation, an error occurs. The following solutions provide a fix to various problems related to IP address configuration.

Have further question about computers? Leave in comments and I will make a video about it.

I keep getting the error The program can't start because WDSUTIL.dll is missing from your computer. Try reinstalling the program to fix this problem. Knowing how to fix it won't help me

I also kept getting this error. ended up resetting my S33 Modem and my entire mesh wifi Deco X75 system. I was getting frustrated until I ran into a community forum for TP Link X75 routers. It seems that there's a known issue with certain routers, may not just be TP Link, the issue is called WAN/LAN auto sensing, the issue occurs after a reboot or firmware update which then will cause the LAN internet connection to go faulty creating the "Valid IP Config error" the router basically assigns port 1 in my case as the WAN, so no LAN would be detected. Well I moved my LAN ethernet to port 2 and problem immediately solved. Hope that helps anyone with similar hardware. save you the pain I went through by having to reinstall windows, as well as my network devices. So short of it, try moving your cable from one port to another, good luck.
