Wireless-N Business Notebook Adapter
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-N Business Notebook Adapter. Setting up your network and your Wireless-N
Business Notebook Adapter is easier than ever.
adapter: a device that adds network functionality
to your PC.
The Wireless-N Notebook Adapter is the simple way to add or upgrade wireless connectivity in your notebook
computer. Just slide it into your notebook's PC Card slot and enjoy incredible high-speed wireless network
access while retaining true mobility.
network: a series of computers or devices
connected for the purpose of data sharing,
storage, and/or transmission between users.
The Wireless-N Notebook Adapter uses the very latest wireless networking technology, Wireless-N (draft
802.11n). By overlaying the signals of multiple radios, Wireless-N's “Multiple In, Multiple Out” (MIMO) technology
multiplies the effective data rate. Unlike ordinary wireless networking technologies that are confused by signal
reflections, MIMO actually uses these reflections to increase the range and reduce “dead spots” in the wireless
coverage area. The robust signal travels farther, maintaining wireless connections significantly farther than
standard Wireless-G.
802.11n: a wireless networking draft standard that
specifies a maximum data rate of up to 600Mbps
(300Mbps is supported by this device), an operating
frequency of 2.4GHz, and backward compatibility with
802.11b/g devices.
With Wireless-N, the farther away you are, the more speed advantage you get. It works great with standard
Wireless-G and -B equipment, but when both ends of the wireless link are Wireless-N, the throughput can be
increased even more by using twice as much radio band.
802.11g: a wireless networking standard that
specifies a maximum data transfer rate of 54Mbps
and an operating frequency of 2.4GHz.
The incredible speed of Wireless-N makes it ideal for media-centric applications like streaming video and Voice
over IP telephony; and gives you plenty of bandwidth to run multiple media-intense data streams through the
network at the same time, with no degradation in performance. Get your notebook connected to Wireless-N,
Wireless-G, and Wireless-B networks with the Wireless-N Business Notebook Adapter from Linksys.
802.11b: a 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?
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.
encryption: encoding data transmitted in a network
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, wherever your work takes
you, without cables. Access the web or use instant messaging to communicate with your virtual office from
wherever you may be. You will also be able to connect with any of the growing number of public hotspots in
coffee shops, airport lounges, hotels and convention centers. Your wireless connection is protected by industrialstrength WPA2 encryption.

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
topology: the physical layout of a network.
access point: a device that allows wirelessequipped computers and other devices to
communicate with a wired network
ad-hoc: a group of wireless devices
communicating directly with each other (peerto-peer) without the use of an access point.
infrastructure: a wireless network that is
bridged to a wired network via an access point.
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.
roaming: the ability to take a wireless device
from one access point's range to another without
losing the connection.
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.
ssid: your wireless network's name.
Network Layout
The Wireless-N Business Notebook Adapter uses draft 802.11n, the latest wireless networking technology. It is
backward compatible with previous 802.11g and 802.11b equipment. 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.
How will wireless networking technology help with my business?
Keeping your business connected to the Internet and managing networking in your office without wires give you
the freedom to create a dynamic office environment that changes and grows as your business needs change and
grow. The Linksys Wireless–N Business Notebook Adapter will not only let you communicate sensitive data in a
wireless setting, but also give you the security and management options within your monitored networks. Linksys
designed our wireless products to be simple to set up and feature the advances of the latest data encryption
methods and Security Monitor functions.
How long does it take for new AP and new client alerts to appear in the alert lists?
Periodic polling is used to report alerts, so the AP and wireless client won’t be overwhelmed. It may take up to
five minutes for the alert to appear in the alert lists.
Can non-administrative users have pop-up alerts appear on their screens?
Yes, if the administrator enables the feature, receive pop-up alerts, on the users’ wireless network monitors.
Can users turn off the pop-up alerts?
Pop-up alerts are disabled by default and are enabled by the administrator on other stations to aid him or her with
monitoring the airspace. Only someone with administrative rights or a designate of the administrator can turn off
the pop-up alerts.
What if a user turns off the Linksys wireless network monitor utility and only uses the Windows Zero
Configuration to connect to the wireless network?
The user will not be able to enjoy the benefits of the Linksys utility, including participation in classification and
security monitoring, which helps the administrator to detect intrusions and policy violations and improve the
state of the network. For example, if the wireless network monitor utility is not used, the user might compromise
the network by inadvertently associating with an Untrusted AP.
My new AP is automatically classified as untrusted when I try to classify using the “Vendor OUI” filter.
Why does this happen?
It is possible that the device is new and the Vendor OUI of the AP was not available when Linksys released our
software. In this case, visit the website: http://standards.ieee.org/regauth/oui/index.shtml and add it to the
Allowed Vendor List. The Vendor OUI is the first three octets (the first 6 digits) of the MAC address.

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. This type of network will not communicate with any wired network.
Appendix A: Troubleshooting
Frequently Asked Questions
54
Wireless-N Business Notebook Adapter
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
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).
Appendix A: Troubleshooting
Frequently Asked Questions
55
Wireless-N Business Notebook Adapter
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.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the
802.11 standard.
What is WPA?
WPA is Wi-Fi Protected Access, a wireless security protocol that can be used in conjunction with a RADIUS server.
What is RADIUS?
RADIUS is Remote Authentication Dial-In User Service, which uses an authentication server to control network
access.

Appendix D: 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/WPA2 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 D: Wireless Security
Security Precautions
61
Wireless-N Business Notebook Adapter
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: WPA-Personal, WPA Enterprise, and Radius. WPA-Personal 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 Enterprise 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 D: 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.
62
Wireless-N Business Notebook Adapter
WPA-Personal. 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 Enterprise. 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 Enterprise offers two encryption methods, TKIP and
AES, with dynamic encryption keys.
WPA2. WPA2 is a wireless security standard that defines stronger encryption, authentication and key
management than WPA.
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.
