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.

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

network: a series of computers or devices
connected for the purpose of data sharing,
storage, and/or transmission between users.

ssid: 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.

infrastructure: a wireless network
that is bridged to a wired network via
an access point.

adapter: a device that adds
network functionality to your PC.

ethernet: IEEE standard network protocol that
specifies how data is placed on and retrieved
from a common transmission medium.

access point: a device that allows wireless­equipped computers and other devices to
communicate with a wired network. Also used
to expand the range of a wireless network.

Host Name and Domain Name. These fields allow you to supply a host and domain name for the
Router. Some ISPs, usually cable ISPs, require these names as identification. You may have to check
with your ISP to see if your broadband Internet service has been configured with a host and domain
name. In most cases, leaving these fields blank will work.

MTU. MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet
transmission. Select Manual if you want to manually enter the largest packet size that will be
transmitted. The recommended size, entered in the Size field, is 1500. You should leave this value in the
1200 to 1500 range. To have the Router select the best MTU for your Internet connection, keep the
default setting, Auto.

network. The default IP Address is 192.168.16.1, and the default Subnet Mask is 255.255.255.0. In most cases,
keeping the default values will work.

DHCP Server Setting

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The
Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to
each computer on your network. If you choose to enable the Router’s DHCP server option, you must make sure
there is no other DHCP server on your network.

DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you
don’t want a DHCP server, then select Disabled (no other DHCP features will be available).

Static DHCP. Every time a PC reboots, it is assigned a new local IP address by the Router. If you want a PC to be
assigned the same IP address every time it reboots, then click the Static IP button.

On the DHCP Client List screen, enter the static local IP address in the Assign this IP field, and enter the MAC
address of the PC in the To this MAC field. Then click the Enabled checkbox. When you have finished your entries,

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain
name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other
server behind the Router.

Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers, DynDNS.org or
TZO.com. If you do not want to use this feature, keep the default setting, Disabled.

building a route to an entire network, be sure that the network portion of the IP address is set to 0. For
example, the Router’s standard IP address is 192.168.16.1. Based on this address, the address of the routed
network is 192.168.16, with the last digit determining the Router’s place on the network. Therefore you would
