The Wireless-G Broadband Router with SpeedBooster is really three devices in one box. First, there's the Wireless Access Point, which lets you connect Wireless-G, Wireless-B, and other performance-enhanced SpeedBooster devices to the network. 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.
