The Linksys WRT54G2 Wireless-G Broadband Router is really three devices in one box. First there is the Wireless Access Point which lets you connect Wireless-G or Wireless-B devices to the network. There is also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices. Connect four PCs directly or daisy-chain out to 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.
