The Linksys Wireless-G Broadband Router is really three devices in one box. First, there's the Wireless Access Point, which lets you connect Wireless-G or 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. 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, files, and other resources such as printers and hard disk storage space. To protect your data and privacy, the Wireless-G Broadband Router can encode all wireless transmissions using 128-bit WEP encryption, and also supports industrial-strength Wi-Fi Protected Access (WPA) wireless security. The Router protects your PC from most known Internet attacks with a powerful Stateful Packet Inspection firewall. It can also serve as a DHCP Server, supports VPN pass-through, and can be configured to filter internal users' access to the Internet. And even with all this power, set up is a snap with the web browser-based configuration utility. With the Linksys Wireless-G Broadband Router at the center of your home or office network, you can share a high-speed Internet connection, files, printers, and multi-player games with the flexibility, speed, and security you need.
