Windows 10: Windows 11 Setup not recognizing ethernet connection

I suppose this is a driver issue, I've already tried to do OOBE\BYPASSNRO and it doesn't work anymore.

New Windows 11 Professional PC not recognized by router with wired ethernet connection?

Hi

Welcome to Microsoft community.

It sounds like you've already taken a thorough approach to troubleshooting the issue. Since you've ruled out many common factors, I'll provide a few more steps you can try to diagnose and potentially resolve the problem of your new Windows 11 Professional PC not being recognized by your router with a wired Ethernet connection:

1. Driver Update and Reinstallation:
   
   • While you mentioned that you installed the Realtek Ethernet driver, it's worth double-checking if there are any updated drivers available from the motherboard manufacturer's website. Sometimes, motherboard-specific drivers can help ensure compatibility.
     
2. Static IP Configuration:
   
   • Try assigning a static IP address to your Windows 11 PC. This can sometimes help in situations where automatic IP assignment is causing issues. Configure the static IP within the Windows network settings and ensure it's within the same subnet as your router.
     
3. Network Reset:
   
   • Open the Windows 11 "Settings" app.
     
   • Go to "Network & internet" > "Status."
     
   • Scroll down and click on "Network reset."
     
   • Follow the prompts to reset your network settings. This will remove and reinstall all network adapters and reset your network settings to their default.
     
4. Driver Uninstallation and Clean Install:
   
   • Uninstall the Realtek Ethernet driver completely.
     
   • Reboot your computer.
     
   • Install the latest driver you downloaded from Realtek or your motherboard manufacturer's website.
     
5. Network Troubleshooter:
   
   • Run the built-in Network Troubleshooter in Windows 11:
     
     1. Right-click on the network icon in the system tray.
        
     2. Select "Troubleshoot problems."
        
     3. Follow the prompts to let Windows attempt to diagnose and fix network issues.
        
6. Consider Another Network Adapter:
   
   • If the issue persists, you might consider getting a separate Ethernet PCIe adapter (a different brand) and installing it in your PC. This can help determine if the issue is specifically related to the Realtek adapter.
     
7. Try a Different Router or Connection:
   
   • If possible, try connecting your PC to a different router or network to see if the issue persists. This can help narrow down whether the problem is related to the PC or the network.
     

Remember that network-related issues can be complex, and the solution might require a combination of steps.

Please feel free to let me know if you have any further updates, thanks.

Ethernet cable getting recognized only after uninstalling and re-installing the ethernet driver

Hello all. I have a laptop which came with Windows 11 installed. At first there were no issues but for the past week my Ethernet cable does not get recognized by my laptop. Following the steps I have seen here in similar questions, I unplug my cable, uninstall the Ethernet driver from the Device Manager, Scan for hardware changes (driver gets installed automatically), plug the Ethernet cable and everything works fine. Next time I open my computer the Ethernet might or might not get recognized. I have to do this task almost every time I open my computer. Any suggestions?

 

Computer not recognizing Ethernet cable

Hi Vijay, I appreciate your help.

I will try each step even if I've already done it, just to make sure, and post my results.

A. When I troubleshoot internet connections, it tells me “Plug an ethernet cable into this computer” and says my cable might be broken or disconnected. However of course i have tried a different working cable with no luck.

when I troubleshoot network adapter, it says “plug an Ethernet cable into the network adapter ‘Ethernet’” which of course has already been done so it is not recognizing it.

B. I tried every suggestion/step listed (except for the wifi troubleshooting since my computer doesn't have wifi) and none of them worked.

C. When I run the windows update troubleshooter, it tells me “download and install pending updates” (Maybe it is not up to date because I tried reinstalling windows 10 to see if that would fix the internet, but it did not. I updated it like last week or
something like that) but of course I can't download the updates without internet. If I click “apply this fix” it tells me to plug in an Ethernet cable. But i believe windows 10 was up to date before this issue even began because I updated it just a week ago.

D. I do not understand this step. The guide is confusing to me. It also appears that I have to download tools in order to do this repair. I cannot download anything because my computer cannot connect to the internet. I don't have a USB flashdrive. I did
try reinstalling Windows 10 though and it did not help.
