Home Wireless-G USB Adaptor

Chapter 1: Introduction

Welcome

Thank you for choosing the Home Wireless-G USB Adaptor. With this Adaptor, your wireless networking

experience will be faster and easier than ever.

How does the Adaptor do this? Like all wireless products, the Adaptor 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 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.

By incorporating two fast technologies—USB 2.0 and Wireless-G (802.11g)—the Adaptor delivers data rates up

to 54Mbps. And since the 802.11g and 802.11b standards share the same 2,4GHz radio band, the Adaptor can

still communicate with devices using the popular 802.11b standard.

TheincludedSetupWizardwillwalkyouthroughconfiguringtheAdaptortoyournetwork'ssettings,stepbystep.

Then just connect the Adaptor to your computer’s USB port, so you can enjoy Internet connectivity with your

computer, while retaining true mobility.

Use the instructions in this Guide to help you install and use the Home Wireless-G USB Adaptor. These

instructions should be all you need to get the most out of the Adaptor.

802.11b: an IEEE wireless networking standard

that specifies a maximum data transfer rate of

11Mbps and an operating frequency of 2.4GHz.

adaptor: 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.

Network Topology

Chapter 2: Planning Your Wireless Network

Network Topology

A wireless network is a group of computers, each equipped with one wireless adaptor. Computers in a wireless

network must be configured to share the same radio channel. Several PCs equipped with wireless cards or

adaptors can communicate with one another to form an ad-hoc network.

Linksys wireless adaptors 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

infrastructurenetworkcan talk toany computer ina wired network infrastructure viathe access pointor 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 adaptor 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, provided that they

both share the same channel and SSID.

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.
