Let's try from the bottom up? ip link show will show you the interfaces recognized by the kernel. If this works, it might show you an eth0, an en0, or something like a enp22s0 device. Let's call it "SAM". If any part of SAM reads "down", do this: sudo ip link set up SAM 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. If not, or if you don't think it looks right for your network, you can set one by hand: sudo ip addr set 192.168.0.43/24 dev SAM or you can ask DHCP for one: sudo dhclient SAM Finally, try pinging your gateway router. Let us know how far you get with this, and exactly what the error messages are. -dsr-
