Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-G Broadband Router with SRX400. The Router will allow you to
network wirelessly better than ever, sharing Internet access, files and fun, easily and securely.
How does the Router do all of this? A router is a device that allows access to an Internet connection over a
network. When you use the Router, this access can be shared over the four switched ports or via the wireless
network.
The Wireless-G Broadband Router with SRX400 combines smart antenna technology with standards-based
Wireless-G (802.11g) networking. By overlaying the signals of two Wireless-G compatible radios, the “Multiple In,
Multiple Out” (MIMO) technology effectively doubles the data rate. Unlike ordinary wireless networking
technologies that are confused by signal reflections, MIMO 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 up to 3 times farther than standard Wireless-G.
With SRX, the farther away you are, the more speed advantage you get, and SRX400 works great with standard
Wireless-G and -B equipment, and other flavors of Linksys SRX. But when both ends of the wireless link are
SRX400, the router can increase the throughput even more by using twice as much radio band, yielding speeds
up to 10 times as fast as standard Wireless-G. But unlike other speed-enhanced technologies, SRX400 can
dynamically enable this double-speed mode for SRX400 devices, while still connecting to non-SRX400 wireless
devices at their respective fastest speeds. And SRX400 is a “good neighbor”, always checking for other wireless
devices in the area before gobbling up the radio band.
In addition, the Router can encode all wireless transmissions with industrial-strength WPA encryption to help
protect your data and privacy. The whole network is protected by a Stateful Packet Inspection (SPI) firewall and
NAT technology. All of these security features, as well as full configurability, are accessed through the easy-to-
use, browser-based utility.
But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one printer from different computers
and access data located on another computer's hard drive. Networks are even used for playing multiplayer video
games. So, networks are not only useful in homes and offices, they can also be fun.
