Chapter 1: Introduction
Welcome
Thank you for choosing the Dual-Band Wireless A+G PCI Adapter. With this Adapter, your
wireless networking experience will be faster and easier than ever.
The Linksys Dual-Band Wireless A+G PCI Adapter lets your PC communicate with all three
wireless network standards. With one PCI Adapter, you can connect to Wireless-A (802.11a),
Wireless-G (802.11g) and Wireless-B (802.11b) networks.
Wireless-B networks have a data rate of 11Mbps, and are commonly found in corporate
environments and in homes for household Internet connectivity without the need for running
cables. They're also popping up all over the country in coffee shops, airports, hotels, convention
centers, and other public spaces offering “on the go” connectivity to mobile users.
In high speed or heavy usage environments, Wireless-B is quickly being replaced by a new
standard, Wireless-G, which uses the same 2.4GHz radio band, but at 54Mbps, is almost five
times faster. The third wireless network standard is Wireless-A, which also runs at 54Mbps, but
operates in the less-crowded 5GHz radio band.
Wireless-A is mostly used in corporate installations.
Whichever standard you encounter, the Dual-Band Wireless A+G PCI Adapter is ready to connect.
And it's simple to use. Just run the included Setup Wizard, which will walk you through the
configuration, and insert the PCI Adapter into one of your PC’s empty PCI slots. All wireless
communications can be protected by up to 256-bit encryption, so your data stays secure.
Use the instructions in this Guide to help you set up and install the Adapter. These instructions
should be all you need to get the most out of the Dual-Band Wireless A+G PCI Adapter.

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 SSID.
Before 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 (peerto-
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.
Network Layout
Dual-Band Wireless A+G products offer the most flexibility, because they can connect to 802.11a
networks, or they can connect to networks with 802.11g and/or 802.11b devices—depending on
the settings you configure on the dual-band products.
The Dual-Band Wireless A+G PCI Adapter is compatible with all 802.11a, 802.11b, and 802.11g
routers, as well as access points. It will also communicate with wireless Notebook Adapters for
your laptop computers, wireless PCI adapters for your desktop PCs, and wireless USB adapters
when you want to enjoy USB connectivity. Wireless products will also communicate with wireless
print servers.
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 wired 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.

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 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 Spread- Spectrum (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?
WLAN 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, WLAN offers the encryption function (WEP) to enhance security and access control.
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.
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 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:
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-PSK and WPA-RADIUS. WPA-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
Standard), which utilizes a symmetric 128-Bit block data encryption. WPA-RADIUS offers two
encryption methods, TKIP and AES, with dynamic encryption keys, and it uses a RADIUS
(Remote Authentication Dial-In User Service) server for authentication.
WPA-PSK. If you do not have a RADIUS server, select the type of algorithm you want to use,
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.
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
Most Linksys 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.
Shared Resources
If you wish to share printers, folder, or files over your network, Windows Help provides complete
instructions on utilizing shared resources.
Network Neighborhood/My Network Places
Other PCs on your network will appear under Network Neighborhood or My Network Places
(depending upon the version of Windows you're running). Windows Help provides complete
instructions on adding PCs to your network.

other antenna or transmitter.
IC Statemant
1.Operation is subject to the following two conditions:
1) this device may not cause interference and
2) this device must accept any interference, including interference that may cause undesired
operation of the device.
This device has been designed to operate with an antenna having a maximum gain of 2 dB.
Antenna having a higher gain is strictly prohibited per regulations of Industry Canada. The
required antenna impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the EIRP is not more than required for successful communication.
To prevent radio interference to the licensed service (i.e. co-channel Mobile Satellite systems)
this device is intended to be operated indoors and away from windows to provide maximum
shielding. Equipment (or its transmit antenna) that is installed outdoors is subject to licensing.
Because high power radars are allocated as primary users (meaning they have priority) in
5250-5350 MHz, these radars could cause interference and/or damage to license exempt LAN
devices.
