Re-enable the networking 1. click the "Enable Networking" of the network manager indicator on the upper-right coner of the desktop to disable the networking 2. click the "Enable Networking" again right after the networking is disabled. 3. the system will establish the wire connection automatically if the wire has been plugged in the machine.
