Hi there!
I have ran into a strange problem after months of a working wired internet connection.
Suddenly the network interface (wired) is not working anymore. It is detected by Yast but Yast tells that it is not connected. The machine is dualboot with windows and here the wired connection works, so it is not a cable issue.
I have tried these check commands from another thread:

I just wonder why it is not working. Setup method is wicked.
Hope for suggestions
