Ethernet stopped working on Zero 2 all of a sudden

pifouille

Hi,


the ethernet connexion stopped working all of a sudden on my zero2 board with ubuntu jammy server.
I have a basic knowledge with linux and I am not able to determine whether it's a hardware problem
or some configuration problem.

Here are the things I tried:
- Test with another ethernet cable
- Test with another ethernet port on my router
- reboot my router
- Test on another router
- Burn again ubuntu on another sdcard and boot on it
- a bunch of things with nmtui, nmcli, ethtool, etc.. none can get eth0 up

I am quite lost and I would be very grateful if someone had some idea,
in particular about how to determine wether the port is actually faulty or not.

Thanks!!
