Wireless-G USB Network Adapter with SRX400
Chapter1:Introduction
Welcome
Thank you for choosing the Wireless-G USB Network Adapter with SRX400. With this Adapter, your wireless
networking experience will be faster and easier than ever.
How does the Adapter do this? Like all wireless products, the Adapter allows for greater range and mobility
within your wireless network, whether it’s using the Wireless-G (802.11g) or Wireless-B (802.11b) standard. But
with SRX400, your speed and range are even better than before. And with USB, connection is simple.
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.
PCs equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network.
The included Setup Wizard walks you through configuring the Adapter to your wireless network settings, step by
step. Use the instructions in this Guide to help you set up and connect the Adapter using the Setup Wizard. These
instructions should be all you need to get the most out of the Adapter.

Network Topology
Wireless-G USB Network Adapter with SRX400
Chapter2:PlanningYourWirelessNetwork
Network Topology
A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless
network must be configured to share the same radio channel. Several PCs equipped with wireless cards or
adapters can communicate with one another to form an ad-hoc network.
Linksys wireless adapters also provide users access to a wired network when using an access point or wireless
router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an
infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless
router.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and can double the
effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data
within a network, the effective transmission range in an infrastructure network can be doubled.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your
wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they
both share the same channel and SSID.
Before you consider enabling roaming, choose a feasible radio channel and optimum access point position.
Proper access point positioning combined with a clear radio signal will greatly enhance performance.
infrastructure: a wireless network that is
bridged to a wired network via an access point.
ad-hoc: a group of wireless devices
communicating directly with each other (peer-
to-peer) without the use of an access point.
roaming: the ability to take a wireless device
from one access point's range to another without
losing the connection.
ssid: your wireless network's name.
topology: the physical layout of a network.
access point: a device that allows wireless-
equipped computers and other devices to
communicate with a wired network. Also used to
expand the range of a wireless network

Network Layout
Linksys wireless access points and wireless routers have been designed for use with 802.11b and 802.11g
products. Products using the 802.11g and 802.11b standards can communicate with each other.
Access points and wireless routers are compatible with 802.11b and 802.11g adapters, such as the notebook
adapters for your laptop computers, PCI adapters for your desktop PCs, and USB adapters for when you want to
enjoy USB connectivity. Wireless products will also communicate with a wireless print server.
When you wish to connect your wired network with your wireless network, network ports on access points and
wireless routers can be connected to any of Linksys's switches or routers.
With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at
