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!!
