The Linksys Wireless-G broadband router is really three devices in one box. First, it's a wireless access point, which lets you connect Wireless-G or Wireless-B devices to the network. There's also a built-in four-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.
