The Linksys WRT110 RangePlus Wireless Router is really three devices in one box. There's the Wireless Access Point, which lets you connect to the network without wires. A built-in 4-port full-duplex 10/100 Switch connects your wired-Ethernet devices together. The Router function ties it all together and lets your whole network share a high-speed cable or DSL Internet connection. The Access Point built into the Router uses smart antenna technology to achieve extended range. The Multiple In, Multiple Out (MIMO) technology actually uses these reflections to increase the range and reduce dead spots in the wireless coverage area. The robust signal travels farther, maintaining wireless connections much farther than standard Wireless-G. With MIMO, the farther away you are, the more speed advantage you get. The RangePlus Wireless Router can dynamically enable this double-speed mode for compatible devices, while still connecting to other wireless devices at their respective fastest speeds. To help protect your data and privacy, the Router can encode all wireless transmissions with industrial-strength 256-bit encryption. It can serve as your network's 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 browser-based configuration utility. With the Linksys RangePlus Wireless Router at the center of your home or office network, you can share a high-speed Internet connection, files, printers, and multi-player games, and run media-intensive applications at incredible speeds, without the hassle of stringing wires.
