Chapter 1: Introduction

Welcome

Wireless-G Range Expander

Chapter 1: Introduction

Welcome

Thank you for choosing the Wireless-G Range Expander. This Range Expander will allow you to expand your

network beyond the range of your current access point or wireless router.

How does the Range Expander do this? Once on your network, the Range Expander repeats the signal to all

devices within its range. By placing the Range Expander at the furthest edge of your access point or wireless

router’s signal, it could conceivably double the area of 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. While access points and

wireless routers bridge wireless networks and wired networks, the Range Expander can then take that signal for

networks that use the 802.11b and 802.11g standards and extend it beyond its current range.

Use the instructions in this Guide to help you connect the Range Expander, set it up, and configure it to expand

the range of your Wireless-G and Wireless-B networks. These instructions should be all you need to get the most

out of the Range Expander. 802.11g:anIEEEwireless networkingstandardthat specifies

a maximum data transfer rate of 54Mbps, an operating

frequency of 2.4GHz, and backward compatibility with

802.11b devices.

802.11b: an IEEE wireless networking standard that

specifies a maximum data transfer rate of 11Mbps and an

operating frequency of 2.4GHz.

access point: a device that allows wireless-equipped

computers and other devices to communicate with a wired

network. Also used to expand the range of a wireless network.

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.

router: a networking device that connects multiple networks

together.

Network Topology

Wireless-G Range Expander

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

infrastructurenetwork can talk toany computer in a wirednetwork infrastructure via the access point orwireless

router.

An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and can double the

effectivewireless transmission range for twowireless adapter PCs. Since an access point is able to forwarddata

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.

Should 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.

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 awireless device from one access

point's range to another without losing the connection.

SSID: your wireless network's name.
