Wireless-G Bridge for Phone Adapters

Chapter 1: Introduction

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.

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

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

802.11b: an IEEE wireless networking standard that
specifies a maximum data transfer rate of 11Mbps
and an operating frequency of 2.4GHz.

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.

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.

topology: the physical layout of a network.

ad-hoc: a group of wireless devices
communicating directly with each other (peer­to-peer) without the use of an access point.

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

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

roaming: the ability to take a wireless device
from one access point's range to another without
losing the connection.

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.

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.

IMPORTANT: Using the wrong power adapter may cause malfunction or damage
your equipment.

Appendix A: Troubleshooting

This appendix consists of two parts: “Common Problems and Solutions” and “Frequently Asked Questions.” This
appendix provides solutions to problems that may occur during the installation and operation of the Wireless-G
Bridge for Phone Adapters. Read the description below to solve your problems. If you can't find an answer here,
check the Linksys website at

Common Problems and Solutions

1. The Setup Wizard cannot detect the Wireless-G Bridge for Phone Adapters.

The Bridge cannot be configured over the wireless network. Confirm that the Bridge is properly connected to
your network router or PC running the Setup Wizard. Make sure the Ethernet network cable is securely
connected and the Ethernet LED should be solidly lit or flashing.

2. The speed of the wireless connection is very slow.

If there is significant traffic (“noise”) in your wireless environment, then the speed will drop. Make sure you
have a clear line of sight between your wireless devices. Also, some electrical and electronic devices
generate interference. You can often locate these by checking wireless data transmission speeds by powering
on and off a different device, one at a time.

3. The Linksys phone adapter or IP phone connected to the Bridge does not have a valid IP address.

This problem does not involve the Bridge (the Bridge only provides a connection between the wireless
network and the phone adapter or IP phone). Make sure the phone adapter or IP phone has been configured
properly, so that it is assigned a valid IP address. (The Bridge does not have its own IP address.)

www.linksys.com

.

4. The Setup Wizard reported that the Bridge has successfully connected to the wireless network; however, the
wireless connection does not seem to be working.

There may be an error with the Bridge’s security settings. Make sure you have written down the correct
settings for your wireless network. Then run the Setup Wizard for the Bridge. Check the following:

• If your wireless network has its security enabled, make sure the WEP key and other settings you entered

Wireless-G Bridge for Phone Adapters

What IEEE 802.11g features are supported?

The product supports the following IEEE 802.11g functions:

• CSMA/CA plus Acknowledge protocol

• OFDM protocol

• Multi-Channel Roaming

• Automatic Rate Selection

• RTS/CTS feature

• Fragmentation

• Power Management

What is infrastructure mode?

When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with a
wired network through a wireless access point.

What is roaming?

Roaming is the ability of a portable computer to communicate continuously while the user is moving freely
throughout an area greater than that covered by a single access point. Before using the roaming function, the
workstation must make sure that it is the same channel number with the access point of dedicated coverage
area.

To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each
node and access point, for example, must always acknowledge receipt of each message. Each node must
maintain contact with the wireless network even when not actually transmitting data. Achieving these functions
simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a
system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates
such factors as signal strength and quality, as well as the message load currently being carried by each access
point and the distance of each access point to the wired backbone. Based on that information, the node next
selects the right access point and registers its address. Communications between end node and host computer
can then be transmitted up and down the backbone.

As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in
touch with the original access point or whether it should seek a new one. When a node no longer receives
acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it
then re-registers, and the communication process continues.

What is the ISM band?

The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM
(Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available

worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in
the hands of users around the globe.

What is Spread Spectrum?

Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in
reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for
reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband
transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that
the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to
the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives,
Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).

What is DSSS? What is FHSS? And what are their differences?

Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that
is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical
channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence Spread­Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip
(or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if
one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can
recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low
power wideband noise and is rejected (ignored) by most narrowband receivers.

Would the information be intercepted while transmitting on air?

The Bridge features two-fold protection in security. On the hardware side, as with Direct Sequence Spread
Spectrum technology, it has the inherent security feature of scrambling. On the software side, the Bridge offers a
variety of security methods, including WEP and WPA, to enhance security and access control. For more
information, refer to “Appendix B: Wireless Security.”

What is WEP?

WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the
IEEE 802.11 standard. For more information, refer to “Appendix B: Wireless Security.”

What is WPA?

WPA is Wi-Fi Protected Access, a wireless security protocol that can be used in conjunction with a RADIUS
(Remote Authentication Dial-In User Service) server. For more information, refer to “Appendix B: Wireless
Security.”

Wireless-G Bridge for Phone Adapters

Appendix B: Wireless Security

Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of
Linksys products provide several network security features, but they require specific action on your part for
implementation. So, keep the following in mind whenever you are setting up or using your wireless network.

Security Precautions

The following is a complete list of security precautions to take (at least steps 1 through 5 should be followed):

1. Change the default SSID.

2. Disable SSID Broadcast.

3. Change the default password for the Administrator account.

4. Enable MAC Address Filtering.

5. Change the SSID periodically.

6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce
your network performance.

7. Change the encryption keys periodically.

Security Threats Facing Wireless Networks

Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking
products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the
network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:

Change the administrator’s password regularly. With every wireless networking device you use, keep in mind that
network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only person
who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can change
those settings. So, make it harder for a hacker to get that information. Change the administrator’s password
regularly.

Appendix B: Wireless Security
Security Precautions

NOTE: Some of these security features are
available only through the network router or
access point. Refer to the router or access
point’s documentation for more information.

21

Wireless-G Bridge for Phone Adapters

SSID. There are several things to keep in mind about the SSID:

1. Disable Broadcast

2. Make it unique

3. Change it often

Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be
more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast
the SSID.

Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.)
Hackers know these defaults and can check these against your network. Change your SSID to something unique
and not something related to your company or the networking products you use.

Change your SSID regularly so that any hackers who have gained access to your wireless network will have to
start from the beginning in trying to break in.

MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only
those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with
a random MAC Address.

WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security concerns.
This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job more
difficult.

There are several ways that WEP can be maximized:

1. Use the highest level of encryption possible

2. Use “Shared Key” authentication

3. Change your WEP key regularly

WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Two modes are
available: WPA and WPA2. For encryption, WPA automatically uses Temporal Key Integrity Protocol (TKIP), which
incorporates Message Integrity Code (MIC) to provide protection against hackers. WPA2-Personal only uses
Advanced Encryption Standard (AES) encryption, which is stronger than TKIP and utilizes a symmetric 128-bit
block data encryption.

WPA. Enter a password in the

Appendix B: Wireless Security
Security Threats Facing Wireless Networks

Passphrase

field of 8-63 characters.

IMPORTANT: Always remember that each
device in your wireless network MUST use
the same encryption method and encryption
key or your wireless network will not function
properly.

22

Wireless-G Bridge for Phone Adapters

WPA2. Enter a password in the

Passphrase

field of 8-63 characters.

Implementing encryption may have a negative impact on your network’s performance, but if you are transmitting
sensitive data over your network, encryption should be used.

These security recommendations should help keep your mind at ease while you are enjoying the most flexible
and convenient technology Linksys has to offer.
