Linksys Wireless G routers allow multiple computers to use the same Internet access point without being connected to the broadband modem. Only one computer and the Linksys router need to be connected to the modem. All other computers can tap into the network. Along with computers, other devices such as wireless printers, game consoles and mobile phones enabled with Bluetooth technology also can access the Internet through the Linksys router.
Connect the broadband Internet modem to the computer using an Ethernet cable. Insert one end of the Ethernet cable into the modem Internet port and the other end into the computer Ethernet port.
Connect the Broadband modem to the Linksys Wireless G router's "Internet" port using an Ethernet cable. Connect the computer to one of the Linksys router's four Ethernet ports using another Ethernet cable.
