Wireless-G Broadband Router with SRX400
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.

Chapter 1: Introduction
What’s in this Guide?
Wireless-G Broadband Router with SRX400
PCs on a wired network create a Local Area Network. They are connected with Ethernet cables, which is why the
network is called “wired”.
PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network. The Router bridges
wireless networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate
with each other.
With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet
access—and even play games. All the while, the Router protects your networks from unauthorized and
unwelcome users.
You should always use the Setup CD-ROM when you first install the Router. If you do not wish to run the Setup
Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the Router, set it up, and
configure it to bridge your different networks. These instructions should be all you need to get the most out of the
Wireless-G Broadband Router with SRX400.

Network Topology

Chapter 2: Planning Your Wireless Network
Network Topology
A wireless local area network is exactly like a regular local area network (LAN), except that each computer in the
wireless network uses a wireless device to connect to the network. Computers in a wireless network share the
same frequency channel and SSID, which is an identification name shared by the wireless devices belonging to
the same wireless network.
Ad-Hoc versus Infrastructure Mode
Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure
and ad-hoc. An infrastructure configuration is a wireless and wired network communicating to each other
through an access point. An ad-hoc configuration is wireless-equipped computers communicating directly with
each other. Choosing between these two modes depends on whether or not the wireless network needs to share
data or peripherals with a wired network or not.
If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral,
such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure
mode. The basis of Infrastructure mode centers around a wireless router or an access point, which serves as the
main point of communications in a wireless network. The Router transmits data to PCs equipped with wireless
network adapters, which can roam within a certain radial range of the Router.
You can arrange the Router and
multiple access points to work in succession to extend the roaming range, and you can set up your wireless
network to communicate with your Ethernet hardware as well.
If the wireless network is relatively small and needs to share resources only with the other computers on the
wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless
transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or
access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to
communicate with computers on a wired network. And, of course, communication between the wireless-
equipped computers is limited by the distance and interference directly between them.
Network Layout
The Wireless-G Broadband Router has been specifically designed for use with both your 802.11b and 802.11g
products. Now, products using these standards can communicate with each other.
