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 Internet phone 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 have set up your
Internet phone service 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
provides a 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.

Wireless-G Broadband Router with 2 Phone Ports
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 this User 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 2: Planning Your Wireless Network
Network Topology
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 an access point or wireless router, such as
the Wireless-G Broadband Router with 2 Phone Ports, 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.
infrastructure: a wireless network
that is bridged to a wired network via
an access point.
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.
network: a series of computers or
devices connected for the purpose of
data sharing, storage, and/or
transmission between users.
ethernet: IEEE standard network
protocol that specifies how data is
placed on and retrieved from a common
transmission medium.

Network Layout
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 2 Phone Ports has been specifically designed for use with both your
802.11b and 802.11g products. It is compatible with all 802.11b and 802.11g adapters, such as the Notebook
Adapters for your laptop computers, PCI Adapters for your desktop PCs, and USB Adapters when you want to
enjoy USB connectivity. The Broadband Router will also communicate with the Wireless PrintServer and Wireless
Ethernet Bridges.
When you wish to connect your wireless network with your wired network, you can use the Broadband Router’s
four Ethernet network ports. To add more ports, any of the Broadband Router's Ethernet network ports can be
connected to any of Linksys's switches.
With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at
www.linksys.com for more information about products that work with the Wireless-G Broadband Router with
2 Phone Ports.

Placement Options
There are two ways to place the Router. The first way is to place it horizontally on a surface, so it sits on its four
rubber feet. The second way is to mount it on a wall. This option uses the Router’s four wall-mount slots on its
bottom panel. The distance between two adjacent slots is 62 mm (2.44 inches).
To use the wall-mount option, follow these instructions:
1. Make sure you have four screws that are size #4—this indicates a diameter measurement of 2.845 mm
(0.112 inches).
2. Determine where you want to mount the Router.
3. Drill four holes into the wall. Make sure adjacent holes are 62 mm (2.44 inches) apart.
4. Insert a screw into each hole, and leave 5 mm (0.2 inches) of its head exposed.
5. Maneuver the Router so the wall-mount slots line up with the four screws.
6. Place the wall-mount slots over the screws and slide the Router down until the screws fit snugly into the
wall-mount slots.
