Chapter 1: Introduction
Welcome
Thank you for choosing the Compact Wireless-G USB Adapter. With this Adapter, your wireless networking
experience will be faster and easier than ever.
Like all wireless products, the Adapter allows for greater range and mobility within your wireless network. This
Adapter communicates over the 802.11g wireless standard, up to 54 Mbps. Connecting to your PC via the USB
port means that this Adapter leaves the PC’s slots open for other purposes.
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 will walk you through configuring the Adapter to your network’s settings, step by step.
Once you’re connected, you can keep in touch via e-mail, access the Internet, and share files and other resources
such as printers and network storage with other computers on the network. At home, you can surf online or use
instant messaging to chat with friends while sitting out on the patio. Your wireless connection is protected by up
to 256-bit encryption.
You'll also be able to connect with any of the growing number of public wireless hotspots springing up in coffee
shops, airport lounges, hotels and convention centers.
Linksys recommends using the Setup Wizard on the Setup CD-ROM for first-time installation of the Adapter. You
can also refer to the instructions in this Guide to help you install and configure the Adapter. These instructions
should be all you need to get the most out of the Compact Wireless-G USB Adapter.

Chapter 2: Planning Your Wireless Network
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 enabling you consider 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.
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
ad-hoc: a group of wireless devices
communicating directly with each other (peerto-peer) without the use of an access point
infrastructure: a wireless network that is
bridged to a wired network via 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
Network Layout
Use the Compact Wireless-G USB Adapter to add your computer to your network of Wireless-G and Wireless-B
products. 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
