Welcome

Wireless-G Broadband Router with RangeBooster

Chapter 1: Introduction

Welcome

Thank you for choosing the Linksys Wireless-G Broadband Router with RangeBooster. The Wireless-G Broadband

Router with RangeBooster will allow you to network wirelessly better than ever, sharing Internet access, files and

fun, easily and securely and with a greater range of up to twice as far as standard Wireless-G.

How does the Wireless-G Broadband Router with RangeBooster do all of this? A router is a device that allows

access to an Internet connection over a network. With the Wireless-G Broadband Router with RangeBooster, this

access can be shared over the four switched ports or via the wireless broadcast at up to 11Mbps for Wireless-B

or up to 54Mbps for Wireless-G.

Use the WPA standard to secure your wireless network while the whole network is protected through a Stateful

Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. You can also access the

Router’s features through the easy-to-use, browser-based utility.

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 on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is

why the network is called “wired”.

PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the

same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called

a WLAN, or Wireless Local Area Network. The Wireless-G Broadband Router with RangeBooster bridges wireless

networks of both 802.11b and 802.11g standards and wired networks, allowing them to communicate with each

other.

Linksys recommends using the Setup CD-ROM for first-time installation of the Router. If you do not wish to run

the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the

Wireless-G Broadband Router with RangeBooster, set it up, and configure it to bridge your different networks.

These instructions should be all you need to get the most out of the Wireless-G Broadband Router with

RangeBooster.

lan

(local area network): The computers and

networking products that make up the network in

your home or office.

nat

(network address translation): NAT technology

translates IP addresses of a local area network to a

different IP address for the Internet.

wpa

(wi-fi protected access): a wireless security

protocol using TKIP (Temporal Key Integrity Protocol)

encryption, which can be used in conjunction with a

RADIUS server.

spi

(stateful packet inspection)

firewall

: a technology

that inspects incoming packets of information before

allowing them to enter the network.

firewall

: Security measures that protect the

resources of a local network from intruders.

Network Topology

Wireless-G Broadband Router with RangeBooster

Chapter 2: Planning Your Wireless Network

Network Topology

A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each

computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same

frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the

same wireless network.

Ad-Hoc versus Infrastructure Mode

Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure

and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an

access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other.

Choosing between these two modes depends on whether or not the wireless network needs to share data or

peripherals with a wired network or not.

If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral,

such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure

mode. The basis of Infrastructure mode centers around a wireless router or an access point, such as the

Wireless-G Broadband Router with RangeBooster, which serves as the main point of communications in a

wireless network. The Router transmits data to PCs equipped with wireless network adapters, which can roam

within a certain radial range of the Router.

You can arrange the Router and multiple access points to work in

succession to extend the roaming range, and you can set up your wireless network to communicate with your

Ethernet hardware as well.

If the wireless network is relatively small and needs to share resources only with the other computers on the

wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless

transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or

access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to

communicate with computers on a wired network. And, of course, communication between the wireless-

equipped computers is limited by the distance and interference directly between them.

Network Layout

The Wireless-G Broadband Router with RangeBooster has been specifically designed for use with both your

802.11b and 802.11g products. Now, products using these standards can communicate with each other.

infrastructure

: a wireless network that is bridged

to a wired network via an access point.

ssid

(service set identifier): your wireless network’s name.

ad-hoc

: a group of wireless devices

communicating directly to each other (peer-to-

peer) without the use of an access point.
