Bug Description
I experience what seems the exact copy of the issue here after I have connected my Dell laptop to a Dell Monitor with an embedded Ethernet over USB-C/Thunderbolt (and USB-B High Speed Upstream Cable). Suddenly no network connection and it can not be restored for a long time or until reboot.
