Linksys WRT54G3G-VN Information:
The Linksys WRT54G3G-VN Wireless-G Router for Mobile Broadband is really three devices in one box. First, there's the Wireless Access Point, which lets you connect both screaming fast Wireless-G (802.11g at 54Mbps) and Wireless-B (802.11b at 11Mbps) devices to the network. Second, it’s 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. Thirdly, the Router function ties it all together and lets your whole network share a Mobile Broadband Internet connection (requires a Mobile Broadband Data Card, available separately). You can also use a standard Ethernet attached Internet connection, like a cable or DSL modem, if available.
Once your computers are connected to the Router and the Internet, they can communicate with each other too, sharing document files, a printer, storage space, and other resources. To protect your data and privacy, the Wireless-G Router for Mobile Broadband can encode all wireless LAN transmissions securely with WEP or WPA Personal encryption. The Router can serve as a DHCP Server, has a powerful SPI firewall to protect your PCs against intruders and most known Internet attacks, and supports VPN pass-through. Configuration is a snap with the web-based configuration utility. With the Wireless-G Router for Mobile Broadband, you can create a secure wireless network with Internet connectivity, anywhere that Mobile Broadband Internet service is available.
