Wireless-G Business USB Network Adapter with RangeBooster
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-G Business USB Network Adapter. Setting up your network and your
Wireless-G Business USB Network Adapter is easier than ever.
The Wireless-G USB Network Adapter is the simple way to add or upgrade wireless connectivity in your computer.
Just connect it into your computer's USB port and enjoy incredible high-speed wireless network access while not
having to run cable wires.
RangeBooster technology increases your wireless network's range up to two times, and its throughput by up to
35%. Unlike ordinary wireless technologies that are confused by signal reflections, RangeBooster uses two
smart receivers at each end to detect and decode reflected signals at distances where standard technologies
give up. You'll find that "dead spots" in the wireless coverage area are reduced, too.
But what does all of this mean?
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.
Once you're connected, you can keep in touch with your e-mail, access the Internet, and share files and other
resources such as printers and network storage with other computers on the network, wherever your work takes
you, without cables.
The Advanced security features makes this solution ideal for your business. Advanced wireless security using WiFi Protected Access™ (WPA2 Enterprise) with up to 256-bit encryption, and the new Wireless Security Monitoring
functionality gives your business the visibility and protection it needs. When used with a Linksys WAP200, the
Wireless Security Monitoring alerts you of possible wireless intruders and vulnerabilities in the wireless network
deployment.
adapter: a device that adds network functionality
to your PC.
network: a series of computers or devices
connected for the purpose of data sharing,
storage, and/or transmission between users.
802.11g: a wireless networking standard that
specifies a maximum data transfer rate of 54Mbps
and an operating frequency of 2.4GHz.
802.11b: a wireless networking standard that
specifies a maximum data transfer rate of 11Mbps
and an operating frequency of 2.4GHz.
encryption: encoding data transmitted in a 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.

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 each 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, if they both share the
same channel and SSID.
Before 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
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 as the PC
Cards for your laptop computers, PCI Cards for your desktop PC, and USB Adapters for when you want to enjoy
USB connectivity.
When you wish to connect your wired network with your wireless network, the network ports on the access
points and wireless routers can be connected to Linksys 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.
