The Linksys Wireless-G Broadband Router is really three devices in one box. First, theres the Wireless Access Point, which lets you connect both screaming fast Wireless-G (802.11g at 54Mbps) and Wireless-B (802.11b at 11Mbps) devices to the network. Theres also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Connect four PCs directly, or attach more hubs and switches to create as big a network as you need. Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection. Once your computers are connected to the Router and the Internet, they can communicate with each other too, sharing resources and files. All your computers can print on a shared printer connected anywhere in the house.Power Requirements: DC: 12VDC, Consumption: 0.5A.1 year hardware limited warranty, Lifetime award-winning online support tools.
