A cable modem can link your home with the Internet, but the modem itself doesn't get the job done. It's necessary to pass the data coming through the modem to a computer. This process can be accomplished one of two ways--either by connecting a computer directly to the modem or by connecting a wireless router to the modem and accessing the Internet through a home wireless network. The physical steps involved in setting up a modem to router connection are simple. Motorola's SB5101 SURFboard cable modem is capable of 30 Mbps performance when connected to compatible networks.
Plug an Ethernet cable into the Ethernet jack of a wireless router. The Ethernet jack looks and operates like a phone line jack; it's just a bit bigger. There is a single Ethernet input jack on the modem, labeled "Input."
Grasp the other end of the Ethernet cable. Plug it into the Ethernet jack on the back panel of the Motorola modem.
Plug the power adapter of the router into a wall socket or power strip. Follow standard router instructions to set up the wireless network.
