Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-G PCI Adapter. With this Adapter, your wireless networking experience will
be faster and easier than ever.
Like all wireless products, the Adapter allows for greater range and mobility within your wireless network. This
adapter communicates over the 54Mbps 802.11g wireless standard, which is almost five times faster than
802.11b. But since they share the same 2.4GHz radio band, the Adapter can also communicate with the widely
used 11Mbps 802.11b standard.
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 will walk you through configuring the adapter to your network's settings, step by step.
Then just slide it into your computer's PCI Card slot and enjoy network access with the freedom of wireless.
Once you're connected, you can keep in touch with your e-mail, access the Internet, and share files and other
resources such as printers and network storage with other computers on the network. At home, you can surf the
web or use instant messaging to chat with friends while sitting out on the patio. Your wireless connection is
protected by the new, industrial-strength security of Wireless Protected Access (WPA).
Get connected to current-standard 802.11b networks today, and be prepared for the future with the Wireless-G
PCI Adapter from Linksys.

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.
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 wireless-equipped
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
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 enabling you consider 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 2: Planning your Wireless Network
Network Topology
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.
Wireless-G PCI Adapter with SpeedBooster
Network Layout
Linksys wireless access points and wireless routers have been designed for use with 802.11a, 802.11b, and
802.11g products. With 802.11g products communicating with the 802.11b standard and some products
incorporating both “a” and “g”, products using these standards can communicate with each other.
Access points and wireless routers are compatible with 802.11a, 802.11b and 802.11g adapters, such at the PC
Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB
connectivity. Wireless products will also communicate with the wireless PrintServer.
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.

Frequently Asked Questions
Can I run an application from a remote computer over the wireless network?
This will depend on whether or not the application is designed to be used over a network. Consult the
application’s user guide to determine if it supports operation over a network.
Can I play computer games with other members of the wireless network?
Yes, as long as the game supports multiple players over a LAN (local area network). Refer to the game’s user
guide for more information.
What is the IEEE 802.11b standard?
It is one of the IEEE standards for wireless networks. The 802.11b standard allows wireless networking hardware
from different manufacturers to communicate, provided that the hardware complies with the 802.11b standard.
The 802.11b standard states a maximum data transfer rate of 11Mbps and an operating frequency of 2.4GHz.
What IEEE 802.11b features are supported?
The product supports the following IEEE 802.11b functions:
• CSMA/CA plus Acknowledge protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
• Power Management
What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to
communicate directly with each other. The ad-hoc wireless network will not communicate with any wired
network.
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 user to communicate continuously while 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
Appendix A: Troubleshooting
Frequently Asked Questions
27
Wireless-G PCI Adapter with SpeedBooster
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 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.

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.
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.
7. Change the WEP 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.
SSID. There are several things to keep in mind about the SSID:
Appendix B: Wireless Security
Security Precautions
30
Wireless-G PCI Adapter with SpeedBooster
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. Three modes are
available: Radius-PSK, WPA Radius, and Radius. Radius-PSK gives you a choice of two encryption methods: TKIP
(Temporal Key Integrity Protocol), which utilizes a stronger encryption method and incorporates Message
Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes
a symmetric 128-Bit block data encryption. WPA RADIUS offers two encryption methods, TKIP and AES, with
dynamic encryption keys. RADIUS (Remote Authentication Dial-In User Service) utilizes a RADIUS server for
authentication.
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
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.
31
Wireless-G PCI Adapter with SpeedBooster
WPA-PSK. If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, and enter a
password in the Passphrase field of 8-63 characters.
WPA RADIUS. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS
server is connected to the Router or other device.) WPA Radius offers two encryption methods, TKIP and AES,
with dynamic encryption keys.
RADIUS. WEP used in coordination with a RADIUS server. (This should only be used when a RADIUS server is
connected to the Router or other device.)
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.

Appendix C: Windows Help
All wireless products require Microsoft Windows. Windows is the most used operating system in the world and
comes with many features that help make networking easier. These features can be accessed through Windows
Help and are described in this appendix.
TCP/IP
Before a computer can communicate with an access point or wireless router, TCP/IP must be enabled. TCP/IP is a
set of instructions, or protocol, all PCs follow to communicate over a network. This is true for wireless networks
as well. Your PCs will not be able to utilize wireless networking without having TCP/IP enabled. Windows Help
provides complete instructions on enabling TCP/IP.
