Chapter 1: Introduction
Welcome
Thank you for choosing the Compact Wireless-G USB Network Adapter with SpeedBooster. 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. Connecting to your PC via the USB port means that this Adapter leaves the PC’s
slots open for other purposes. This adapter communicates over the 802.11g wireless standard, one of the newest
wireless standards, to communicate with your network.
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.
And now, with SecureEasySetup, setting up your network and your Compact Wireless-G USB Network Adapter is
easier than ever.
Use the instructions in this Guide to help you connect the Adapter, set it up, and configure it for your network.
These instructions should be all you need to get the most out of the Adapter.
network: a series of computers or devices
connected for the purpose of data sharing, storage,
and/or transmission between users.
adapter: a device that adds network functionality to your PC.
802.11g: an IEEE wireless networking standard that specifies a
maximum data transfer rate of 54Mbps, an operating frequency
of 2.4GHz, and backward compatibility with 802.11b devices.

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.
ad-hoc: a group of wireless devices
communicating directly with each other (peerto-peer) without the use of an access point
access point: device that allows wirelessequipped computers and other devices to
communicate with a wired network.
infrastructure: Configuration in which a
wireless network 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

Compact Wireless-G USB Network Adapter with SpeedBooster
Network Layout
Linksys wireless access points and wireless routers have been designed for use with 802.11a, 802.11b, and
802.11g products. With 802.11g products communicating with the 802.11b standard and some products
incorporating both “a” and “g”, products using these standards can communicate with each other.
Access points and wireless routers are compatible with 802.11a, 802.11b and 802.11g adapters, such at the PC
Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB
connectivity. Wireless products will also communicate with the wireless PrintServer.
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
www.linksys.com for more information about wireless products.
802.11b: an IEEE wireless networking standard
that specifies a maximum data transfer rate of
11Mbps and an operating frequency of 2.4GHz.
switch: device that is the central point of connection for
computers and other devices in a network, so data can
be shared at full transmission speeds.
router: a networking device that connects multiple networks
together, such as a local network and the Internet.
