Blue screen when using Ethernet connection on laptop

Smags416

I am encountering a Windows 11 Pro Blue Screen when my Ethernet cable is plugged into my laptop or the docking station. The blue screen occurs within 1-10 mins from log in. The computer runs fine when the cable is not connected and using WIFI to connect to the network. When researching this issue on the Internet, I learned that others had to remove their AV software to fix this problem. So, I removed Bitdefender and the problem stopped occurring; I was able to work continuously for long periods of time. When I reinstalled Bitdefender the problem occurred again.

Are there any suggestions on how to fix this issue?

Configuration:

HP Probook 450 G5

Windows 11 pro 24H2 with latest updates

Realtek drivers were reinstalled as my initial effort to fix this problem.

Bitdefender Total Security with latest updates.

Thank you.

Hi @Smags416

Try disabling the "port scan security" in the firewall and see if that helps.

Otherwise try disabling features one by one to like the firewall to see which one is causing the issue.
