Windows 10: Blue Screen when ethernet cable is connected

Hello there,my PC crashes every time I connect the Ethernet cable. This happens after starting the PC and about 10 - 15 seconds after my desktop is displayed. And this every time. I did not recognize the error for a long time until I removed the Ethernet cable once and then realized that the PC no longer crashes blue screen or green screen since I use Win 11 Insider. I recently had a driver problem regarding the Ethernet. I installed the VPN program Surfshark and until then everything worked fine. However, after I uninstalled Surfshark, I noticed that my PC was connecting to the WLAN instead

Ethernet cable not working.

You need to solve your problem one step at a time, e.g. like so:

• Connect your CAT5 cable directly to your router. If it does not work, replace the cable.
• Connect the cable to your TP-Link wall plug. If it does not work, reconfigure or replace the wall plug.

 

Ethernet cable settings

Hi Campbell,

Thank you for writing to Microsoft Community Forums.

Please reply to the follow questions to get a better understanding on the issue:

• What is the model number of your laptop?
  
• Do you have a yellow exclamation on the network icon after connecting the cat 7 cable?
  

However, you can follow the troubleshooting steps from
Fix network connection issues in Windows.

Also, I suggest you to check the laptop manual or laptop manufacturer to know whether the Ethernet port of your laptop supports cat 7 cable.

Hope it helps.

Ethernet Cable connection in Dorms

Press start
Type in "network", and select "Network and Sharing Centre"
Click on Change Adapter Settings at the left.
Check if you have two, one ethernet and one wireles.
If you only have one, wireless, your ethernet driver is not installed (refer to website of manufacturer for driver)
If you have two, and the ethernet cable is plugged in but the adapter is not connected - buy a new cable.
Check with university site management to see if they have purposefully disabled physical network connection.
