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?
Try booting into a live image of a debian distro (pick any one you want that can boot into a live image), then try the Ethernet port. Is it working? If not, either your bios shut it off or the port is broken. Several years ago, I had a broken wifi adaptor that happened to break at the exact same time as (or super close thereto) me installing GIMP. No way GIMP caused it. If the port does work on the live image, then it’s likely a driver issue with your install. Try it and let us know the results.
live image had the same problems. I bought a wifi usb stick after work from my local computer store (Linux support was advertised on the wrapping) and it works so far. Must be the hardware but the mainboard is only a year old…
