The Linksys Wireless-G WRT54G3G-AT Router for 3G/UMTS Broadband is really three devices in one box. First, there's the Wireless Access Point, which lets you connect both screaming fast Wireless-G and Wireless-B devices to the network. There's also a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Connect four PCs directly, or attach more hubs and switches to create as big a network as you need. The Router function ties it all together and lets your whole network share a 3G/UMTS or GPRS Internet connection (requires Vodafone Mobile Connect 3G/UMTS data card). You can also use a standard Ethernet attached Internet connection, like a cable or DSL modem.
