The Wireless-G WRT54GL Broadband Router is really three devices in one box. First, there's the Wireless Access Point, which connects both screaming fast Wireless-G (IEEE 802.11g at 54 Mbps) and Wireless-B (IEEE 802.11b at 11 Mbps) devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connects wired-Ethernet devices together. Connect four PCs directly, or attach more hubs and switches to create as big a network as needed. Finally, the Router function ties it all together and the whole network share a high-speed cable or DSL Internet connection.
