Thanks for your reply. enp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 I omited the second line which contained what looks like a mac address. > > If any part of SAM reads "down", do this: > > sudo ip link set up SAM ip link set up enp2s0 No output here but the link is still down. > > and make sure the cable is plugged in. :) > > Now let's set an address. > > ip addr show SAM > that might show you an IPv4 address.

So I will try to set one manually as above... It didn't like 'set', so I used 'add' The address it is supposed to be is 192.168.1.43, you came close to guessing it! ip addr add 192.168.1.43/24 dev enp2s0 This produced a message in the GUI saying a connection was established to enp2s0 but the link is still down. > Finally, try pinging your gateway router. > > Let us know how far you get with this, and exactly what the > error messages are. > ping 192.168.1.1 PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data. >From 192.168.1.43 icmp_seq=1 Destination Host Unreachable ... etc I tried this before the other commands too, and got this: ping 192.168.1.1 connect: Network is unreachable
