New build, all works but ethernet

Anyway everything works fine except for the ethernet port. Under device manager it is listed as "Ethernet Controller", under the category of "unknown devices" (along with several other unknown devices).

 

Only on Windows 11 with Lenovo USB-C dock Ethernet not working

Hello ,

Good to see you in Microsoft Community.

Firstly, could you let me know the specific system version (OS Build)? You can check it by pressing Win + X > System > Windows specifications, click “Copy” and paste it in your next reply.

You can follow the steps below:

1. I suggest that you check if the Ethernet adapter is enabled in the Device Manager. To do this, follow these steps:
   
   1. Press the Windows key + X and select Device Manager from the list.
      
   2. Expand the Network adapters section.
      
   3. Look for the Ethernet adapter and check if it is enabled. If it is disabled, right-click on it and select Enable device.
      
2. If the Ethernet adapter is already enabled, try updating the driver for the Ethernet adapter. To do this, follow these steps:
   
   1. Press the Windows key + X and select Device Manager from the list.
      
   2. Expand the Network adapters section.
      
   3. Right-click on the Ethernet adapter and select Update driver.
      
   4. Select Search automatically for updated driver software and follow the on-screen instructions.
      
3. If updating the driver does not resolve the issue, try uninstalling and reinstalling the Ethernet adapter driver. To do this, follow these steps:
   
   1. Press the Windows key + X and select Device Manager from the list.
      
   2. Expand the Network adapters section.
      
   3. Right-click on the Ethernet adapter and select Uninstall device.
      
   4. Restart your computer.
      
   5. Windows will automatically reinstall the driver for the Ethernet adapter.
      
4. If none of the above steps work, you can try resetting the network settings on your Windows 11 computer. To do this, follow these steps:
   
   1. Press the Windows key + I to open Settings.
      
   2. Click on Network & internet.
      
   3. Scroll down and click on Network reset.
      
   4. Click on Reset now and follow the on-screen instructions.
      

If anything is unclear, please do not hesitate to let me know.
