The RangePlus Wireless Router is really three devices in one box. First, there`s the Wireless Access Point, which lets you connect to the network without wires. There`s also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Finally, the Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection. With the Linksys RangePlus Wireless Router at the center of your home or office network, you can share a high-speed Internet connection, files, printers, and multi-player games, and run media-intensive applications at incredible speeds, without the hassle of stringing wires!
