Hey. Short story: I activated Secure boot on my MSI Mainboard and bootet in my new Debian. I realized that I had no wired internet connection and rebooted the system to deactivate secure boot again. Problem is that now my whole Ethernet is borked? I don’t get a connection in Debian or my older OpenSuse partition and the Debian install USB stick says that the connection doesn’t work. Of course I deinstallieren Windows and now this happens. Tried already a different cable . Any idea what I could do?
Thanks everyone. I tried everything but only with very limited success. I have a very unstable connection that loads very very slow and is basically unusable. I will check tomorrow again if there’s damage and if WiFi is affected too. It’s already night here so time for a little sleep.
If you have a wifi adapter, run on that for now, and dc the ethernet. Probably a hardware problem.
