This computer is used to serve SSH remote access.The ethernet cable and network are all working fine.However, the computer has suddenly lost connection and now shows '?' sign for the wired connection.I pinged all the sites but got 100% loss - obviously bc of the connection issue
I already tried sudo nmcli networking on, sudo apt update && sudo apt upgrade but none of those made a change.
Here are the few details below:
