Chapter 1: Introduction
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.

Chapter 2: Planning Your Wireless Network
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.
