Chapter 1: Introduction
Welcome
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-G Broadband Router with 2 Phone Ports. This Router will allow you
to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. Plus, after you
have set up your Vonage service, you can make phone or fax calls using your Internet connection.
How does the Router 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 2 Phone Ports, this access can be shared over the four
switched ports or via the wireless broadcast at either up to 11Mbps for Wireless-B or up to 54Mbps for
Wireless-G. In addition, the WPA standard provides greater security opportunities while the whole network is
protected through NAT technology. All of these security features, as well as full configurability, are accessed
through the easy-to-use browser-based utility.
But what does all of this mean?
Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share
Internet access, so you don’t need more than one high-speed Internet connection. After you set up your Vonage
account, you can also use your Internet access to make Internet phone or fax calls, even while you’re surfing the
Internet. Plus, 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. All the while, the Router
protects your networks from unauthorized and unwelcome users. So, networks not only are useful in homes and
offices, but also can 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”.
ethernet: an IEEE standard network
protocol that specifies how data is
placed on and retrieved from a common
transmission medium.
lan (local area network): the computers
and networking products that make up
the network in your home or office.
browser: an application program that
providesa way to look at and interact
with all the information on the World
Wide Web.
mbps: one million bits per second; a unit
of measurement for data transmission.
nat (network address translation): NAT
technology translated 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.

2Chapter 1: Introduction
What’s in this Guide?
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, which is sometimes
called a Wireless Local Area Network (WLAN). The Router bridges wireless networks of both 802.11b and
802.11g standards and wired networks, allowing them to communicate with each other.
To create your network, install and set up the Router. To guide you through the process, Linksys strongly
recommends that you run the Setup Wizard on the Setup CD-ROM. If you prefer to manually set up the Router,
use the instructions in the Quick Installation or this Installation and Troubleshooting Guide to help you. These
instructions should be all you need to get the most out of the Wireless-G Broadband Router with 2 Phone Ports.
What’s in this Guide?
This guide covers the basic steps for setting up a network with a router. After going through “Chapter 3: Getting
to Know the Router,” most users will only need to use the following chapters:
• Chapter 4: Connecting the Router
This chapter instructs you on how to connect the Router to your cable or DSLmodem, PCs, and telephones
(or fax machines).
• Chapter 5: Configuring the Router
This chapter explains how to configure the Router using your web browser and the Router’s Web-based
Utility. You will configure the Router using the settings provided by your ISP.
When you’re finished with the basic steps, then you are ready to connect to the Internet.
802.11b: an IEEE wireless networking
standard that specifies a maximum data
transfer rate of 11Mbps and an operating
frequency of 2.4GHz.
802.11g: an IEEE wireless networking
standard that specifies a maximum data
transfer rate of 54Mbps, an operating
frequency of 2.4GHz, and backward
compatibility with 802.11b devices.
