I went from Windows 10 to Windows 11 on my custom built PC a couple months back. Ever since I made the switch, my PC won’t connect to the network at all, not through Wi-Fi or Ethernet. When I ran the network troubleshooter, it gave me an error message of “Ethernet doesn’t have a valid IP Configuration”. When I looked up fixes for this problem, I tried every solution out there, rebooting the PC, resetting the router, rebooting my network drivers, turned off fast startup, reset TCP/IP through the Command Prompt, and cleared the network cache. I even hooked my PC straight into the network tower and it still didn’t do anything. Is there any way I can fix this without having to boot up Windows 10 again since I hear reverting back is a hassle.?

where the cable plugs in…
Are the lights on the NIC flashing?
Are they on the modem or router?
Have you tried resetting the network through commands and or windows back to factory on the affected system?
May need to remove the network information in the device manager making sure to select Show hidden Devices? -
There is a solid green light and a blinking yellow light, which should mean that the hardware connection is fine. I’ll have to try doing a factory reset for windows, is that done through the settings or is it through commands?Originally posted by RustysComment

Making sure you understand NOT resetting Windows Resetting the network setting on that system.

Go into settings > Network and Internet > Ethernet > Change adapter options
Right click on properties and scroll down to Internet Protocol Version 4 (TCP/IPv4) and select Properties, ensure that this is set to “Obtain and IP address automatically” for both boxes"
Try opening Command Prompt and issuing these two commands separately:
ipconfig /release
ipconfig /renew
Does this fix the issue?
If not, please issue the command:
ipconfig /all
and post a picture of the return from this command. (You can cut out the connection-specific DNS Suffix if you are uncomfortable with your provider/rough location being shown.Comment

The first two commands didn’t work for me, so I did ipconfig /all. You mentioned something about the DNS Suffixes, but those values are just blank. Is that a problem?Originally posted by PyroComment

Please post a picture of the response you get when issuing ipconfig /allComment

You’re not being assigned an IP address,
Copy and paste these into command prompt one by one in the order listed:
ipconfig /release “Ethernet 2”
ipconfig /release “Wi-Fi”
ipconfig /renew “Ethernet 2”
ipconfig /renew “Wi-Fi”
Are you still plugged in through Ethernet?
Are you running Dual NICs?Comment

Here are my results from running those commands. I am connected to the ethernet directly to the router, and I don’t believe I am running dual NICs.Comment
