Chapter 1: Introduction
Welcome
Wireless-G Bridge for Phone Adapters
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-G Bridge for Phone Adapters. With this Bridge, your wireless networking
experience will be faster and easier than ever.
How does the Bridge do this? You can put your Linksys phone adapter or IP phone almost anywhere, without the
cost and hassle of running network cables. The Bridge was specially designed to convert your phone adapter or
IP phone into a wireless device, so it can connect to your home network without an Ethernet cable. This lets you
put your phone where it's most convenient for you, and not be limited to the area around your Internet
connection.
To make installation even more convenient, the Bridge shares electrical power with the phone adapter or IP
phone, so only one power adapter is needed. To get connected, just plug your existing power adapter's power
jack into the Bridge, and connect the power and data cables of the Bridge to the phone adapter or IP phone. The
included Setup Wizard makes it easy to configure the Bridge for your wireless network. To protect your data and
privacy, all wireless transmissions can be encrypted with WEP or industrial-strength, Wi-Fi Protected Access
(WPA/WPA2) security.
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 equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network.
The included Setup Wizard walks you through configuring the Bridge for your wireless network, step by step. Use
the instructions in this Guide to help you set up and connect the Bridge as you run the Setup Wizard. These
instructions should be all you need to get the most out of the Wireless-G Bridge for Phone Adapters.

Network Topology
Wireless-G Bridge for Phone Adapters
Chapter 2: Planning Your Wireless Network
Network Topology
A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless
network must be configured to share the same radio channel. Several PCs equipped with wireless cards or
adapters can communicate with one another to form an ad-hoc network.
Linksys wireless adapters also provide users access to a wired network when using an access point or wireless
router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an
infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless
router.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and can double the
effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data
within a network, the effective transmission range in an infrastructure network can be doubled.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your
wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they
both share the same channel and SSID.
Before you consider enabling roaming, choose a feasible radio channel and optimum access point position.
Proper access point positioning combined with a clear radio signal will greatly enhance performance.
infrastructure: a wireless network that is
bridged to a wired network via an access point.
ad-hoc: a group of wireless devices
communicating directly with each other (peer-
to-peer) without the use of an access point.
roaming: the ability to take a wireless device
from one access point's range to another without
losing the connection.
ssid: your wireless network's name.
topology: the physical layout of a network.
access point: a device that allows wireless-
equipped computers and other devices to
communicate with a wired network. Also used to
expand the range of a wireless network

Products using the 802.11g and 802.11b standards can communicate with each other.
Access points and wireless routers are compatible with 802.11b and 802.11g adapters, such as the notebook
adapters for your laptop computers, PCI adapters for your desktop PCs, and USB adapters for when you want to
enjoy USB connectivity. Wireless products will also communicate with a wireless print server.
Now with the Wireless-G Bridge for Phone Adapters, you can add wireless connectivity to your LInksys phone
adapter or IP phone (compatible model numbers: PAP2, SPA1001, SPA2000, SPA2002, SPA3000, SPA2100,
SPA841, SPA842, SPA941, SPA942, and SPA9000).
When you wish to connect your wired network with your wireless network, network ports on access points and
wireless routers can be connected to any of Linksys's switches or routers.
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 wireless products.
router: a networking device that connects multiple
networks together
switch: a data switch that connects computing devices
to host computers, allowing a large number of devices
to share a limited number of ports

Overview
Wireless-G Bridge for Phone Adapters
Chapter 3: Getting to Know the Wireless-G Bridge for Phone
Adapters
Overview
The Bridge has two LEDs, a Power port, and a permanently attached cable.
The LEDs
The Bridge has two LEDs to indicate network activity. (Not all versions of the Bridge have LEDS; however, all
Bridges work the same, with or without LEDs.)
Ethernet Green. The Ethernet LED lights up when the Bridge has an active connection to the wired network.
It flashes when the Bridge is experiencing wired network activity. The LED is not lit when the Bridge
has no active connection to the wired network.
Wireless Green. The Wireless LED lights up when the Bridge is connected to the wireless network. It flashes
when the Bridge is experiencing wireless network activity. The LED is not lit the Bridge is not
connected via wireless.
When the Bridge’s firmware is being upgraded, the Ethernet and Wireless LEDs alternate flashing.
The Port
The Bridge does not include its own power adapter; instead, it uses the power adapter of the Linksys phone
adapter or IP phone.
Power The Power port only supports a 5 V, 2 A, DC power adapter, which was included with your Linksys
phone adapter or IP phone. Do NOT connect any other type of power adapter to the Bridge.
