Welcome

Wireless-G Travel Router with SpeedBooster

Chapter 1: Introduction

Welcome

Thank you for choosing the Linksys Wireless-G Travel Router with SpeedBooster. The Wireless-G Travel Router

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

easily and securely while away from home.

How does the Wireless-G Travel Router with SpeedBooster do all of this? The Router has a built-in access point,

which lets you connect SpeedBooster-enhanced and regular Wireless-G and Wireless-B devices to the network.

There's also an Ethernet port to connect your wired PC.

The Router function ties it together and lets your PCs

share a wired or wireless Internet connection. The travel-friendly form factor includes a built-in power supply and

antenna, and it comes with a travel case. Just plug the Router directly into the wall, and connect the hotel's fast

Internet service cable.

Then use the Router's push button setup feature to easily connect and configure your

wireless devices. You just push the button on the Router and on your other SecureEasySetup-enabled wireless

device to automatically create a WPA or WEP encryption-secured wireless connection.

You can also use multiple

devices on a single hotspot account in a coffee shop or airport lounge and be protected with WPA Personal

encryption or a powerful SPI firewall. The Router also supports VPN pass-through and it can serve as a DHCP

Server.

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 Travel Router with SpeedBooster bridges wireless

networks of 802.11a, 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 Travel Router with SpeedBooster, set it up, and configure it to bridge your network. These instructions

should be all you need to get the most out of the Wireless-G Travel Router with SpeedBooster.

ethernet

: an IEEE standard network protocol that

specifies how data is placed on and retrieved from

a common transmission medium.

lan

Network Topology

Wireless-G Travel Router with SpeedBooster

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 Travel Router with SpeedBooster, 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 Travel Router with SpeedBooster has been specifically designed for use with your 802.11b and

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