There are two ways to connect a computer to your High-Speed Internet network: by wireless connection and by wired connection. This article explains how to set up a wired connection. Simply choose your operating system to begin:
If you have computers located close to the router, you can use an Ethernet (RJ-45) cable to plug each computer directly into the back of the router. Connect one end of the cable to the computer's network interface card (NIC) and the other end to an empty port at the back of your High-Speed Internet modem.
If you have more computers than ports on your router, you can add an Ethernet hub or switch to expand the number of ports. Run another Ethernet or crossover cable from the "Uplink" port of the new hub or switch to a yellow Ethernet port on the router. For help in buying an Ethernet hub or switch, consult your local computer store and explain what you're trying to do.
Connecticut Customers: Not sure which device you have? Look for a sticker on the router with information that includes "2WIRE" or "Motorola". Read these instructions for connecting multiple computers.
