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?
 
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
Click to expand...

ipconfig /renew
Click to expand...

Does this fix the issue?

If not, please issue the command:

ipconfig /all
Click to expand...

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.

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

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?

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.
 
Interesting. 🤔

Let's get some more information:

Download and run speccy.

Once you have ran speccy, follow the instructions to upload a snapshot found here.


To publish a Speccy profile to the Web:

  1. In Speccy, click File, and then click Publish Snapshot.
  2. In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.
  3. Speccy publishes the profile and displays a second Publish Snapshot dialog box. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

Since I can't connect my PC to the internet, I cant download the software
 
First uninstall any third party antivirus applications and or firewalls.

On a working machine, or your phone.
Download the complete internet repair tool.
Save it to the desktop of your computer with the issue.
Then unzip it there, right click and run the x64 bit version and run it as admin, with all options ticked.
Once it completes if it does not ask to reboot your computer then do so manually.

My apologies, I should have been more clear on how to do so offline. It seems that Mal has you covered with his expertise. 🙂

I followed these instructions and ran the program, but the problem is still there
