Plug one end of the Ethernet cable into the "WAN" port on the back of your router -- located to the immediate left of the antenna -- and plug the opposite end of the cable into the Ethernet port on the back of your broadband modem labeled "Internet" or "WAN."
Connect your computer and router via a second Ethernet cable. Plug one end of the Ethernet cable into the "LAN1" port on the back of your router, and plug the other end of the cable into the your computer's network card. Use the additional LAN ports to add more wired devices to your network such as a gaming console or another computer.
