Great, let's start with the ethernet port.
Plug in an ethernet cable -- check both ends are connected.
Start a terminal window.
ip link show
will get you a list of recognized network interfaces. The first
one will be lo, the loopback, and you can ignore that one.
With luck, one of them is named
en0 or enp4s0 or eth0 or something like that:
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq
state UP mode DEFAULT group default qlen 1000
link/ether a8:a1:59:08:50:79 brd ff:ff:ff:ff:ff:ff
At this point, you can run
sudo dhclient enp4s0
(or whatever the name of the ethernet port is)
and it should tell you that it has connected and acquired an
address. Then you have Internet service, and other things can be
addresses.
Did a network interface starting with w show up? Tell us about
it.
run
lspci -v |grep Network
and tell us what it says.
