The ASUS motherboard has a 2nd Ethernet port. When I plug the cable in, the LED goes yellow, and the modem shows a the green LED. But I can’t seem to get connected.
When I ping the modem, I get a ‘Network unreachable’. When I look at network settings, it says the cables are unplugged for both ports.
How can I get Ubuntu run a wizard to recognise & setup the second Ethernet port?
