The ip commands will tell you how your network interfaces are set up.
wireshark can be used to look at traffic.
The likes on your physical network devices can tell you if there is a
connection and often will flash when data is being sent over the device.
You can inject your own traffic with ping or traceroute.
iptables can be used to check your firewall setup.
