Plug a networkcable, also called an Ethernet patch or straight-through cable, into the network port onthe computer. Plug the other end into the network device or wall jack.After connecting the network cable, look at the LEDs, or link lights, next to the Ethernetport on the NIC to see if any activity is occurring.
