Compact Wireless-G USB Network Adapter with SpeedBooster

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.

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.

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.

Network Topology

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.

access point: 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 (peer-

to-peer) without the use of an access point

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
