Things You'll Need
Instructions
Connect one end of the Ethernet cable to the modem or router, depending on your network setup. It does not matter which end you connect, as both ends are the same. If you are using only a modem, disconnect the computer from the modem and connect your Ethernet cable.
If you have a router, connect the Ethernet cable into one of the router's I/O ports, which is typically on the back of the router.
Connect the other end of the Ethernet cable to the I/O port in the back of the Xbox 360 (see I/O port image).
Turn on your Xbox 360.
