Choosing a WLAN
Configuring a WLAN
Identifying a WLAN
Surveying the Site of Your WLAN
Factors Affecting Range
A wireless network connects computers without using network cables. Computers use
radio communications to send data between each other. You can communicate directly
with other wireless computers, or connect to an existing network through a wireless
access point. When you set up your wireless adapter, you select the operating mode for
the kind of wireless network you want. You can use your wireless adapter to connect to
other similar wireless devices that comply with the 802.11 standard for wireless
networking.
Choosing a Wireless LAN
Wireless LANs can operate with or without access points, depending on the number of
users in the network. Infrastructure mode uses access points to allow wireless computers
to send and receive information. Wireless computers transmit to the access point, the
access point receives the information and rebroadcasts it to other computers. The
access point can also connect to a wired network or to the Internet. Multiple access
points can work together to provide coverage over a wide area.
Peer-to-Peer mode, also called Ad Hoc mode, works without access points and allows
wireless computers to send information directly to other wireless computers. Ad Hoc
Mode is only supported in 802.11b and 802.11g networks. You can use Peer-to-Peer
mode to network computers in a home or small office or to set up a temporary wireless
network for a meeting.
Configuring a Wireless LAN
There are three basic components that must be configured for an 802.11 wireless LAN to
operate properly:
●
●
Network Name: Each wireless network uses a unique Network Name to identify
the network. This name is called the Service Set Identifier (SSID). When you set up
your wireless adapter, you specify the SSID. If you want to connect to an existing
network, you must use the name for that network. If you are setting up your own
network you can make up your own name and use it on each computer. The name
can be up to 32 characters long and contain letters and numbers.
Profiles: When you set up your computer to access a wireless network, the
wireless client manager creates a profile for the wireless settings that you specify.
If you want to connect to another network, you can scan for existing networks and
make a temporary connection, or create a new profile for that network. After you
create profiles, your computer will automatically connect when you change
●
locations.
Security: The 802.11 wireless networks use encryption to help protect your data.
Wired equivalent privacy (WEP) uses a 64-bit or 128-bit shared encryption key to
scramble data. Before a computer transmits data, it scrambles the data using the
secret encryption key. The receiving computer uses this same key to unscramble
the data. If you are connecting to an existing network, use the encryption key
provided by the administrator of the wireless network. If you are setting up your
own network you can make up your own key and use it on each computer.
❍ Wi-Fi Protected Access (WPA) is a security enhancement that strongly
increases the level of data protection and access control to a WLAN. WPA
mode enforces 802.1x authentication and key-exchange to strengthen data
encryption. WPA utilizes its Temporal Key Integrity Protocol (TKIP). TKIP
provides important data encryption enhancements that include a per-packet
key mixing function, a message integrity check (MIC) named "Michael", an
extended initialization vector (IV) with sequencing rules, and a also re-keying
mechanism. Using these improvement enhancements, TKIP protects against
WEP's known weaknesses.
❍ Cisco Client Extention (CCX) is a server and client 802.1x authentication
via a user-supplied logon password. When a wireless access point
communicates with a Cisco LEAP-enabled RADIUS (Cisco Secure Access
Control Server (ACS) server), Cisco LEAP provides access control through
mutual authentication between client wireless adapters and the wireless
network and provides dynamic, individual user encryption keys to help
protect the privacy of transmitted data.
Identifying a Wireless Network
Depending on the size and components of a wireless LAN, there are many ways to
identify a wireless LAN:
●
●
●
●
●
The Network Name or Service Set Identifier (SSID): Identifies a wireless
network. All wireless devices on the network must use the same SSID.
Extended Service Set Identifier (ESSID): A special case of SSID used to identify
a wireless network that includes access points.
Independent Basic Service Set Identifier (IBSSID): A special case of SSID used
to identify a network of wireless computers configured to communicate directly with
one another without using an access point.
Basic Service Set Identifier (BSSID): A unique identifier for each wireless device.
The BSSID is the Ethernet MAC address of the device.
Broadcast SSID: An access point can respond to computers sending probe
packets with the broadcast SSID. If this feature is enabled on the access point, any
wireless user can associate with the access point by using a blank (null) SSID.
Surveying the Site of Your Wireless LAN
Conducting a site survey for your wireless LAN is the most crucial step in the process of
setting up a wireless network. It greatly reduces the amount of troubleshooting you will
have to do once you have the wireless LAN set up and ready for connection testing. To
conduct a site survey, you will need the following tools:
●
●
●
An access point (or laptop computer) that is set up to be the transmitter. It should
be mounted near and at the same height as the designated location of your
wireless LAN.
A laptop that will act as the mobile receiver. It must contain your site survey
software.
An area or building map, which will be used to plot the strength of your signals.
Once you have the tools you need, you are ready to survey the inside of the building.
Launch the site survey software on the mobile receiver laptop and carry it around in the
intended wireless LAN area to test the signal strength. Be sure to also check the signal
strength of each intended access point location. If you encounter problems while
surveying the site, make sure your transmitter laptop is not located on a wall containing
metal, such as an air-conditioning duct, which will interfere with the range of your signal.
Simply move the transmitter and test the signal strength again. For users to have
seamless coverage when moving from access point to access point, the signal levels at
each point must overlap. There is software available that will seamlessly hand off
changing signal levels from one access point to another.
Your building's infrastructure can sometimes interfere with the microwave signal, but
finding the location and cause of the interference will allow you to figure out the best
place to mount your access points for optimal area coverage. Microwave signals travel in
all directions, which means there is one access point for a multi-floor building. However,
the range is highly dependent on the material used to construct the flooring, especially
metal materials. Once your signal strength is strong inside the building, you are ready to
check the strength outside the building. To do so, simply carry the mobile receiver laptop
as far down the street or around the building as you can go without losing significant
signal strength. If possible, you should be aware of the types of networks being used by
the companies on the floors above and below you, so that you can work together in
harmony. With wireless networks, security is very important and if you communicate with
those around you, you are better prepared to select the right channels, as well as the
best location for access points.
Factors Affecting Range
Although access points can transmit signals up to 60 feet away in an area with many
walled barriers or as much as 500 feet away in a large open area, the range is affected
by the following factors:
●
●
●
●
Building materials, such as steel and drywall, can shorten the range of the radio
signals.
Physical layout of the area can interfere with the signals and cause them to be
dropped.
Electronic noise from cell phones, microwave ovens, or other devices on the same
frequency can interfere with the transmission of the signals.
Range is inversely proportional to data rate, so the faster that the signals are sent,
the less distance they will travel.
Taking these factors into consideration when you survey the site for your WLAN is key to
providing all of your users with undisturbed mobile connectivity. Using multiple access
points will, of course, reduce the impact of these factors if your area has dividing walls
throughout.
What is a Site Survey?
A site survey is an in-depth examination and analysis of a proposed wireless LAN site.
The purpose of a site survey is to determine the number of access points needed, the
types of antennas needed, and the best placement for those access points and
antennas. Although the goal of a site survey is simple, the means of arriving at that goal
are not. Some of the steps involve taking measurements, but most involve experience,
trial and error, and a little guesswork rather than numbers and figures. When to Perform
a Site Survey Intel® recommends that you perform a site survey prior to installing a
wireless LAN. Site surveys are especially important when:
●
●
You are installing a new site: Evaluate the placement of the access points and
antennas throughout the proposed site.
You are changing an existing site: When modifying or extending an existing
network structure, re-evaluate the placement of the access points and antennas. If
●
you need a different level of coverage in some areas, you may need to move,
replace, or supplement access points and antennas.
You are physically changing the site: Remodeling may introduce new sources of
interference, such as motors and metal structures within the coverage area of the
access point, even if it does not directly effect the sites where the access points
are located.
Elements of an Effective Site Survey
An effective site survey requires four elements. Failure to commit the appropriate time,
money, and energy to accomplish a proper site survey in advance may result in greater
expenditures of money and time later, when problems arise that require repeated
adjustments to the wireless configuration. The three elements of an effective site survey
are:
1. Examine the network usage problems solved by the wireless LAN.
How many clients need a wireless LAN connection? What areas of the site require
wireless LAN connectivity? How many hours each day is wireless LAN connectivity
required? Which locations are likely to generate the largest amount of data traffic?
Where is future network expansion most likely?
2. Study blueprints of the proposed wireless LAN site.
A site blueprint provides a map of the site as well as the location of objects, such
as walls, partitions, and anything else that could affect the performance of a
wireless LAN. Examining the site blueprint prior to conducting the physical walkthrough helps you identify areas in which wireless equipment is likely to perform
well and areas where it is not. Many obstructions are not readily visible and, in
some cases, a room originally built for a specific purpose, such as a radiology lab,
might have been converted into something completely different, such as a
conference room. The blueprint may also show areas proposed for future building
expansion. To prepare for the next step of the site survey, mark possible wireless
device locations on the blueprint and refer to the marked blueprint during the
physical walk-through and inventory.
3. Conduct a physical walk-through and inventory.
The primary purpose of the physical walk-through is to document any items or
materials near a proposed device location that may interfere with reception or
transmission and affect network performance. Document stock and inventory
levels, current environmental conditions and any materials that may interfere with
the wireless LAN.

LAN Utility Conflict Message
Message dialog "Another wireless LAN utility is communicating with the Intel(R)
PRO/Wireless LAN adapter. To avoid conflicts, Intel(R) PROSet for Wireless has
temporarily disabled its Profile Management features" is displayed. Refer to Enabling
Intel(R) PROSet for Wireless to manage Your Wireless Connections for information.
Using a Profile with an incorrect WEP Encryption Key
When connected to an access point using a profile with an incorrect WEP key encryption,
the task tray icon and the General page will both indicate good signal strength and that
you are associated with the AP. However, when you attempt to send data to the AP
using this profile, because of the incorrect WEP key encryption, authentication cannot be
established to acquire an IP address from the AP to allow data transfer.
Refer to the following WEP encryption and authentication settings.
Open Authentication with an incorrect WEP 64 or 128-bit encryption key:
●
●
A profile with an incorrect WEP encryption key will allow the wireless adapter to
associate with the access point.
No data transfer
Open Authentication with no WEP encryption:
●
●
Allows association to an access point
Data transfer is allowed
Shared Authentication:
●
Associated to an AP always allows data transfer.
Problems with installation
Windows does not detect the wireless adapter:
1. Remove and re-install the adapter.
2. Uninstall and reinstall the adapter's drivers.
Users are dropped from the wireless network
Suggested causes and solutions:
●
●
●
●
Find out if a person or workgroup moved or if the building has been rearranged.
If two or more users are seated too close to each other, performance can suffer.
Instruct your users to space themselves a small distance apart to keep receivers
from being overloaded.
Delivery trucks with very large metal sides can affect performance by reflecting
destructive signals back into a building. If you have an installation that includes a
shipping dock, check to see if the problem coincides with the arrival of large
trucks.
Personal “systems” can also interfere with your network. Wireless speakers,
●
●
cordless earphones, some Bluetooth devices, and similar systems can be the
source of an infrequent but hard to find the problem. Some systems do not conform
to wireless regulations. Shut off suspect devices or remove them from the area.
If possible, remove and reinstall your new software. Conflicts with other resident
software packages are always a possibility, and they are not always the fault of the
newest addition. Sometimes just starting over fixes the problem.
Swap units around. Does your problem follow the changed units, or is it unique to a
specific location? If it follows the product, the swapped unit could be damaged, or
improperly configured. If the problem stays with the location, try to find out what is
different about that particular room or area.
Range decreases as data rate increases
This is a normal condition. Range is inversely proportional to data rate: the faster the
data, the shorter the range. This has to do with the modulation technology used. Very
fast data rates require extremely complex signal waveforms, where even minor
distortions can result in data errors. Slower data rates are much more tolerant, and
consequently will get through even in the presence of some amount of noise,
interference, distortion and echo.
Signal doesn't pass through a short or thin wall
Range is highly dependent on the physical environment. In a line-of-sight location, with
elevated and calibrated antennas, range predictions are quite accurate. This is not true in
a “typical” office building, where the walls may be simple drywall (which is almost
transparent to microwaves), or could be plaster with metal underneath. Most sites are
somewhere between these two extremes, and consist of a mixture of surfaces. You can’t
tell what is inside a wall by just looking at it, and we can’t tell you exactly what distance
you will achieve. Consider published range information to be typical, average, common
or usual. Do not expect it to be exact.
Signal strength drops when a cell phone is used in the area
Range also depends on the electronic environment. If other equipment that could cause
interference is nearby, the range of your transceiver could vary widely, and could change
suddenly when the other equipment activates. This is particularly true for 802.11b
installations, which share their frequencies with microwave ovens, cordless phones,
wireless hi-fi speakers, electronics toys and similar devices. Try to keep your system
away from other transmitters, and from other sources of electrical noise, such as large
motors, spot welders, and similar “electronically noisy” devices.
Range is shorter than it should be
Repeat some tests late in the evening, or on a weekend, when there may be less
interference. However, some users leave their networks turned all the time so this test is
not foolproof. By all means, try more than one channel. Your range problem may just be
a nearby user whose system uses your present test channel.
Interference from fluorescent lights
If you mount an access point close to fluorescent light fixtures, the lamp glow appears
constant, but inside the lamp tube, ionization appears and disappears 120 times a
second. This can modulate or “chop” an incoming signal and interfere with reception.
When too much range is undesirable
Too much range is not necessarily a good thing. At first it would appear that you would
want as much range as possible, but with the increase in range comes an increase in
interference potential, as your unit hears not only your other units but also manages to
hear the systems of other companies up and down the street. If you have a large
installation, you will also wind up with more than one access point using the same
channel. If a remote unit hears two or more access points, this will slow the network.
Help Prevent access to wireless networks from outside the building
Excess transmit range presents a special reverse problem. For example, putting an
access point adjacent to a second floor bay window invites anyone with the right software
on the street below to pick up and enjoy all network transmissions. We discuss some
possible solutions to this problem further on.
Problems with Network Connectivity
If you cannot connect to the wireless network, try the following:
Check Network Settings
1. From the General page, check that the Network Name (SSID) and operating mode
are correct. If the laptop is configured for ad hoc networking, make sure that the
channel is correct.
2. To correct these settings, click the Networks tab.
3. Select the profile being used.
4. Click the Edit button and make the changes.
Check Security Settings
1.

for either 11g or 11b access points using data transmit rates of 1, 2, 5.5, 6, 9, 11, 12, 18,
24, 36, 48, or 54 Mbps. This connection defaults to 11g access points. The Available
Networks list displays all 11b and 11g access points.
Connect to 802.11g only: The adapter will search for a 11g access point only using data
transmit rates of 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps. The Available Networks
list displays only 11g access points.
Connect to 802.11b only: The adapter will search for the best 11b and 11g access points
using data rates of 1, 2, 5.5, or 11 Mbps. The Available Networks list displays any 11b and
11g access point.
When different modulation settings are used in ad hoc mode, they influence the computer in the
following ways:
●
●
It determines to which ad hoc network we are allowed to connect to.
It determines whom we show in our scan list.
A station in an ad hoc network constantly adapts itself to the current situation in the ad hoc
network as far as other stations capabilities are concerned. Updating of the supported transmit
data rates is done in the following way:
Only the basic rates change. Supported rates of a station never change. At all times the basic
rates advertised by stations in an ad hoc network should be the same, and should reflect the set
of basic rates supported by every station in this ad hoc network. Since basic rates is the actual
information used by a station to decide if it can join the ad hoc network then this is enough to
determine if a station can or cannot connect to this ad hoc network.
Mixed Mode
Mixed mode stations (802.11g and 802.11b) are able to join any ad hoc network they hear.
Joining an ad hoc network
●
●
●
Join an 11b ad hoc network only – keep the supported rates and update the basic rates to
fit the ad hoc network you are joining. Protection (RTS/CTS or CTS-to-self) is on.
Join an 11g ad hoc network only – keep the supported rates and up scale the basic rates
advertised in the beacons. Note that this is not good because the station ceases being a
“mixed mode” and become an 11g only station.
Join an 11a and 11b ad hoc network only – keep the supported rates and update the basic
rates to fit the ad hoc network you are joining.
Initiating an ad hoc network
When initiating a mixed mode ad hoc network the default rates for mixed mode is: 1, 2, 5.5, 11, 6,
12, 18, 24, 36, 48 and 54 Mbps with rates 1, 2 as basic. When other stations join in, the basic
rates are down scaled if required. Protection is on when 11b station are joining.
11b only mode
Joining an ad hoc network
In this mode you can only join an ad hoc network that advertises only basic data rates of 1, 2, 5.5,
or 11 Mbps. So, the list of potential ad hoc networks will include 11b and 11b and 11g, but not
11g. Supported rates remain unchanged, and basic rates are adapted to match those advertised
by the ad hoc network which you are joining in the beacons.
Initiating an ad hoc network
When initiating an 11b only ad hoc network, the following rates 1, 2, 5.5 and 11 Mbps, with 1 and
2 as basic. As other stations join in they down scale their basic rates if required. Protection
(RTS/CTS or CTS-to-self) is on.
11g only mode
Initiate an ad hoc network as an 11g only (1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, or 54 Mbps).
Support joining and down scaling in the same way as in Mixed mode. When initiating such an ad
hoc network the advertised rates are: 1, 2, 5.5, 6, 11, 12, 18, 24, 36, 48 and 54 with 1, 2, 5.5, 6,
11, 12 and 24 Mbps as basic.
11g only stations are able to join any ad hoc network they hear.
Joining an ad hoc network
The basic rates in this case are taken from the beacons.
●
●
●
Join an 11b ad hoc network only – keep the supported rates and down scale the basic rates
to fit the ad hoc network you are joining. Protection (RTS/CTS or CTS-to-self) is on.
Join an 11g ad hoc network only – keep the supported rates and adopt the basic rates
advertised in the beacons.
Join an 11a and 11b ad hoc network only – keep the supported rates and update the
basic rates to fit the ad hoc network you are joining.
Initiating an ad hoc network
When initiating an 11g only ad hoc network the advertised rates are: 1, 2, 5.5, 6, 11, 12, 18, 24,
36, 48 and 54 Mbps with 1, 2, 5.5, 6, 11, 12 and 24 Mbps as basic.
When other stations join in, the basic rates are down scaled if required. Protection (RTS/CTS or
CTS-to-self) is on when 11b station is joining.

Encryption Overview
Security in the WLAN can be supplemented by enabling data encryption using WEP
(Wireless Encryption Protocol). You can choose a 64 or 128 bit level encryption. Also,
the data can then be encrypted with a key. Another parameter called the key index
provides the option to create multiple keys for that profile. However, only one key can be
used at a time. You can also choose to password protect an Intel(R) PROSet for
Wireless profile to ensure privacy. The pass phrase is used to generate a WEP key
automatically. You have the option of either using a pass phrase or entering a WEP key
manually. Using 64-bit encryption, the pass phrase is 5 characters long and you can
choose to enter any arbitrary and easy to remember phrase like Acme1 or enter 10
Hexadecimal numbers for the WEP key corresponding to the network the user wants to
connect to. For 128-bit encryption, the pass phrase is 13 characters long or you can
enter a 26 hexadecimal numbers for the WEP key to get connected to the appropriate
network.
WEP Encryption and Authentication
Wired Equivalent Privacy (WEP) encryption and shared authentication provides
protection for your data on the network. WEP uses an encryption key to encrypt data
before transmitting it. Only computers using the same encryption key can access the
network or decrypt the encrypted data transmitted by other computers. Authentication
provides an additional validation process from the adapter to the access point.
Supported a authentication schemes are Open and Shared-Key authentication:
●
●
Shared-Key authentication is supported using 64-bit and 128-bit WEP encryption
keys.
Open mode does not use an encryption authentication method to associate to a
specific access point.
Network Keys
When Data Encryption (WEP, CKIP or TKIP) is enabled, a network key is used for
encryption. A network key can be provided for you automatically (for example, it might be
provided on your wireless network adapter, or enter it yourself and specify the key length
(64-bits or 128-bit), key format (ASCII characters or hexadecimal digits), and key index
(the location where a specific key is stored). The longer the key length, the more secure
the key. Every time the length of a key is increased by one bit, the number of possible
keys double. Under 802.11, a wireless station can be configured with up to four keys (the
key index values are 1, 2, 3, and 4). When an access point or a wireless station transmits
an encrypted message using a key that is stored in a specific key index, the transmitted
message indicates the key index that was used to encrypt the message body. The
receiving access point or wireless station can then retrieve the key that is stored at the
key index and use it to decode the encrypted message body.
Encryption Static and Dynamic Key Types
802.1x uses two types of encryption keys, static and dynamic. Static encryption keys are
changed manually and are more vulnerable. MD5 authentication only uses static
encryption keys. Dynamic encryption keys are renewed automatically on a periodic basis.
This makes the encryption key(s) more secure. To enable dynamic encryption keys, you
must use 802.1x certificate-based authentication methods, such as TLS or TTLS or
PEAP.

Overview
802.1x authentication is independent of the 802.11 authentication process. The 802.1x
standard provides a framework for various authentication and key-management
protocols. There are different 802.1x authentication types, each providing a different
approach to authentication but all employing the same 802.1x protocol and framework for
communication between a client and an access point. In most protocols, upon the
completion of the 802.1x authentication process, the supplicant receives a key that it
uses for data encryption.
With 802.1x authentication, an authentication method is used between the client and a
Remote Authentication Dial-In User Service (RADIUS) server connected to the access
point. The authentication process uses credentials, such as a user's password that are
not transmitted over the wireless network. Most 802.1x types support dynamic per-user,
per-session keys to strengthen the static key security. 802.1x benefits from the use of an
existing authentication protocol known as the Extensible Authentication Protocol (EAP).
802.1x authentication for wireless LANs has three main components: The authenticator
(the access point), the supplicant (the client software), and the authentication server (a
Remote Authentication Dial-In User Service server (RADIUS). 802.1x authentication
security initiates an authorization request from the WLAN client to the access point,
which authenticates the client to an Extensible Authentication Protocol (EAP) compliant
RADIUS server. This RADIUS server may authenticate either the user (via passwords or
certificates) or the system (by MAC address). In theory, the wireless client is not allowed
to join the networks until the transaction is complete. There are several authentication
algorithms used for 802.1x; MD5-Challenge, EAP-TLS, EAP-TTLS, Protected EAP
(PEAP), and EAP Cisco Wireless Light Extensible Authentication Protocol (LEAP). These
are all methods for the WLAN client to identify itself to the RADIUS server. With RADIUS
authentication, users identities are checked against databases. RADIUS constitutes a set
of standards addressing Authentication, Authorization and Accounting (AAA). Radius
includes a proxy process to validate clients in a multi-server environment. The IEEE
802.1x standard is for controlling and authenticating access to port-based 802.11
wireless and wired Ethernet networks. Port-based network access control is similar to a
switched local area network (LAN) infrastructure that authenticates devices that are
attached to a LAN port and prevent access to that port if the authentication process fails.
How 802.1x authentication works
A simplified description of the 802.1x authentication is:
1. A client sends a "request to access" message to an access point. The access point
requests the identity of the client.
2. The client replies with its identity packet which is passed along to the
authentication server.
3. The authentication server sends an "accept" packet to the access point.
4. The access point places the client port in the authorized state and data traffic is
allowed to proceed.
Refer to Setting up the Client for WEP and MD5 authentication for details about setting
up an 802.1x profile using the Intel(R) PROSet for Wireless utility.
What is a RADIUS?
RADIUS is the Remote Access Dial-In User Service, an Authorization, Authentication,
and Accounting (AAA) client-server protocol for when a AAA dial-up client logs in or out
of a Network Access Server. Typically, a RADIUS server is used by Internet Service
Providers (ISP) to performs AAA tasks. AAA phases are described as follows:
●
●
●
Authentication phase: Verifies a user name and password against a local
database. After the credentials are verified, the authorization process begins.
Authorization phase: Determines whether a request will be allowed access to a
resource. An IP address is assigned for the Dial-Up client.
Accounting phase: Collects information on resource usage for the purpose of
trend analysis, auditing, session time billing, or cost allocation.
Wi-Fi Protected Access* (WPA)
Wi-Fi Protected Access (WPA) is a security enhancement that strongly increases the
level of data protection and access control to a WLAN. WPA mode enforces 802.1x
authentication and key-exchange and only works with dynamic encryption keys. To
strengthen data encryption, WPA utilizes its Temporal Key Integrity Protocol (TKIP).
TKIP provides important data encryption enhancements that include a per-packet key
mixing function, a Message Integrity Check (MIC) named Michael an extended
initialization vector (IV) with sequencing rules, and a also re-keying mechanism. Using
these improvement enhancements, TKIP protects against WEP's known weaknesses.
PEAP
PEAP is a new Extensible Authentication Protocol (EAP) IEEE 802.1x authentication
type designed to take advantage of server-side EAP-Transport Layer Security (EAP-TLS)
and to support various authentication methods, including user's passwords and one-time
passwords, and Generic Token Cards.
Cisco LEAP
Cisco LEAP (EAP Cisco Wireless) is a server and client 802.1x authentication via a usersupplied logon password. When a wireless access point communicates with a Cisco
LEAP-enabled RADIUS (Cisco Secure Access Control Server (ACS) server), Cisco
LEAP provides access control through mutual authentication between client wireless
adapters and the wireless network and provides dynamic, individual user encryption keys
to help protect the privacy of transmitted data.
Cisco Rogue AP security feature
The Cisco Rogue AP feature provides security protection from an introduction of a rogue
access point that could mimic a legitimate access point on a network in order to extract
information about user credentials and authentication protocols which could compromise
security. This feature only works with Cisco's LEAP authentication. Standard 802.11
technology does not protect a network from the introduction of a rogue access point.
CKIP
Cisco Key Integrity Protocol (CKIP) is Cisco proprietary security protocol for encryption
in 802.11 media. CKIP uses the following features to improve 802.11 security in
infrastructure
mode:
●
●
●
Key Permutation
Message Integrity Check
Message Sequence Number
Mixed-Cell
Some access points, for example Cisco 350 or Cisco 1200, support environments in
which not all client stations support WEP encryption, this is called Mixed-Cell Mode.
When these wireless network operate in “optional encryption” mode, client stations that
join in WEP mode, send all messages encrypted, and stations, that join in using standard
mode, send all messages unencrypted. These APs broadcast that the network is not
using encryption, but allow clients to join using WEP mode. When “Mixed-Cell” is
enabled in a profile, it allows you to connect to access points that are configured for
“optional encryption.”
NOTE: Make sure to enable the Advanced Settings Mixed-Cell (Requires Cisco
CCX option) when using Enable Cisco-Client eXtentions in a profile. A Cisco
CCX enabled profile uses CKIP data encryption and 802.1x LEAP authentication.

Setting up Data Encryption and Authentication
Wired Equivalent Privacy (WEP) encryption and shared authentication helps provide
protection for your data on the network. WEP uses an encryption key to encrypt data
before transmitting it. Only computers using the same encryption key can access the
network or decrypt the encrypted data transmitted by other computers. Authentication
provides an additional validation process from the adapter to the access point. The WEP
encryption algorithm is vulnerable to passive and active network attacks. TKIP and CKIP
algorithms include enhancements to the WEP protocol that mitigate existing network
attacks and address its shortcomings.
Open and Shared Key authentication
802.11 support two types of network authentication methods; Open System and Shared
that use 64-bit and 128-bit WEP encryption. Open does not require an encryption
authentication method to associate to a specific access point. Supported authentication
schemes are Open and Shared authentication:
●
●
Using Open authentication, any wireless station can request authentication. The
station that needs to authenticate with another wireless station sends an
authentication management frame that contains the identity of the sending station.
The receiving station or AP will grant any request for authentication. Open
authentication allows any device network access. If no encryption is enabled on the
network, any device that knows the SSID of the access point can gain access to
the network.
Using Shared authentication, each wireless station is assumed to have received a
secret shared key over a secure channel that is independent from the 802.11
wireless network communications channel. Shared key authentication requires that
the client configure a static WEP key. The client access will be granted only if it
passed a challenge based authentication.
Network Keys
When Data Encryption (WEP, CKIP or TKIP) is enabled, a network key is used for
encryption. A network key can be provided for you automatically (for example, it might be
provided on your wireless network adapter, or you can enter it yourself and specify the
key the key length (64-bits or 128-bit), key format (ASCII characters or hexadecimal
digits), and key index (the location where a specific key is stored). The longer the key
length, the more secure the key. Every time the length of a key is increased by one bit,
the number of possible keys double.
Under 802.11, a wireless station can be configured with up to four keys (the key index
values are 1, 2, 3, and 4). When an access point or a wireless station transmits an
encrypted message using a key that is stored in a specific key index, the transmitted
message indicates the key index that was used to encrypt the message body. The
receiving access point or wireless station can then retrieve the key that is stored at the
key index and use it to decode the encrypted message body.
Encryption Static and Dynamic Key Types
802.1x uses two types of encryption keys, static and dynamic. Static encryption keys are
changed manually and are more vulnerable. MD5 authentication only uses static
encryption keys. Dynamic encryption keys are renewed automatically on a periodic basis.
This makes the encryption key(s) more secure. To enable dynamic encryption keys, you
must use 802.1x authentication methods, such as TLS, TTLS, PEAP or LEAP.
Encryption Overview
Security in the WLAN can be supplemented by enabling data encryption using WEP
(Wireless Encryption Protocol). You can choose a 64 or 128 bit level encryption. Also,
the data can then be encrypted with a key. Another parameter called the key index is
provides the option to create multiple keys for that profile. However, only one key can be
used at a time. You can also choose to password protect the profile to ensure privacy.
The pass phrase is used to generate a WEP key automatically. You have the option of
either using a pass phrase or entering a WEP key manually. Using 64-bit encryption, the
pass phrase is 5 characters long and you can choose to enter any arbitrary and easy to
remember phrase like, Acme1, or enter 10 Hexadecimal characters for the WEP key that
matches the network that the connects to. For 128-bit encryption, the pass phrase is 13
characters long or you can enter a 26 hexadecimal characters for the WEP key to get
connected to the appropriate network.
Note: You must use the same encryption type, key index number, and WEP key as other
devices on your wireless network.
How to Enable WEP Encryption

System Administrator Tasks
NOTE: The following information is intended for system administrators.
How to Obtain a Client Certificate
If you do not have any certificates for EAP-TLS, or EAP-TTLS you must get a client
certificate to allow authentication. Typically you need to consult with your system network
administrator for instructions on how to obtain a certificate on your network. Certificates
can be managed from "Internet Settings", accessed from either Internet Explorer or the
Windows Control Panel applet. Use the "Content" page of "Internet Settings".
Windows XP and 2000: When obtaining a client certificate, do not enable strong private
key protection. If you enable strong private key protection for a certificate, you will need
to enter an access password for the certificate each time this certificate is used. You
must disable strong private key protection for the certificate if you are configuring the
service for TLS/TTLS authentication. Otherwise the 802.1x service will fail authentication
because there is no logged in user to whom it can display the prompt dialog.
Notes about Smart Cards
After installing a Smart Card, the certificate is automatically installed on your computer
and can be select from the person certificate store and root certificate store.
Setting up the Client for TLS authentication
Step 1: Getting a certificate
To allow TLS authentication, you need a valid client (user) certificate in the local
repository for the logged-in user’s account. You also need a trusted CA certificate in the
root store.
The following information provides two methods for getting a certificate;
●
●
from a corporate certification authority implemented on a Windows 2000 Server
using Internet Explorer’s certificate import wizard to import a certificate from a file
Getting a certificate from a Windows 2000 CA:
1. Start Internet Explorer and browse to the Certificate Authority HTTP Service (use a
URL such as http://yourdomainserver.yourdomain/certsrv with certsrv being the
command that brings you to the certificate authority. You can also use the IP
address of the server machine, such as"192.0.2.12/certsrv."
2. Logon to the CA with the name and password of the user account you created
(above) on the authentication server. The name and password do not have to be
the same as the Windows logon name and password of your current user.
3. On the Welcome page of the CA select Request a certificate task and submit the
form.
4. On the Choose Request Type page, select Advanced request, then click Next.
5. On the Advanced Certificate Requests page, select Submit a certificate request to
this CA using a form, then click Submit.
6. On the Advanced Certificate Request page choose the User certificate template.
Select "Mark keys as exportable", and click Next. Use the provided defaults
shown.
7. On the Certificate Issued page select Install this certificate.
Note: If this is the first certificate you have obtained, the CA will first ask you
if it should install a trusted CA certificate in the root store. The dialog will not
say this is a trusted CA certificate, but the name on the certificate shown will
be that of the host of the CA. Click yes, you need this certificate for both TLS
and TTLS.
8. If your certificate was successfully installed, you will see the message, "Your new
certificate has been successfully installed."
9. To verify the installation, click Internet Explorer > Tools > Internet Options >
Content > Certificates. The new certificate should be installed in "Personal"
folder.
Importing a certificate from a file
1. Open Internet Properties (right-click on the Internet Explorer icon on the desktop
and select Properties.
2. Click the Certificates button on the Content page. This will open the list of installed
certificates.
3. Click the Import button under the list of certificates. This will start the Certificate
Import Wizard. (Note: Steps 1 through 3 may also be accomplished by doubleclicking the icon for the certificate.
4. Select the file and proceed to the Password page.
5. On the Password page specify your access password for the file. Clear the Enable
strong private key protection option.
6. On the Certificate store page select "Automatically select certificate store based on
the type of certificate" (the certificate must be in the User accounts Personal store
to be accessible in the Configure dialog of the Client; this will happen if ‘automatic’
is selected).
7. Proceed to "Completing the Certificate Import" and click the Finish button.

Setting up the Client for WPA using TKIP encryption and TTLS or
PEAP authentication
Using TTLS authentication: These settings define the protocol and the credentials used
to authenticate a user. In TTLS, the client uses EAP-TLS to validate the server and
create a TLS-encrypted channel between the client and server. The client can use
another authentication protocol, typically password-based protocols, such as MD5
Challenge over this encrypted channel to enable server validation. The challenge and
response packets are sent over a non-exposed TLS encrypted channel.
Using PEAP authentication: PEAP settings are required for the authentication of the
client to the authentication server. In PEAP, the client uses EAP-TLS to validate the
server and create a TLS-encrypted channel between client and server. The client can
use another EAP mechanism, such as Microsoft Challenge Authentication Protocol
(MSCHAP) Version 2, over this encrypted channel to enable server validation. The
challenge and response packets are sent over a non-exposed TLS encrypted channel.
The following example describes how to use WPA with TKIP encryption using TTLS or
PEAP authentication.

CCX Access Point and Client Configurations
The access point provides settings to select different authentication types depending on
the WLAN environment. The client sends an Authentication algorithm field during the
802.11 authentication handshake that takes place between the client and the AP during
connection establishment. The Authentication algorithm values recognized by a CCX
enabled AP is different for the different authentication types. For instance "Network-EAP"
which denotes LEAP has a value of 0x80 while "Open" which is the 802.11 specified
Open authentication and "Required EAP" which requires an EAP handshake exchange
have values of 0x0.
Network-EAP only
AP: For CCX enabled networks using LEAP authentication only the authentication type is
set with "Network-EAP" checkbox selected, and "Open" and "Required EAP" boxes
unchecked. The AP is then configured to allow LEAP clients ONLY to authenticate and
connect. In this case, the AP expects the 802.11 authentication algorithm to be set to
0x80 (LEAP), and rejects clients that attempt authentication with an Authentication
algorithm value 0x0.
Client: In this case the client needs to send out an authentication algorithm value of 0x80
else the 802.11 authentication handshake would fail. During boot, when the Wireless
LAN driver is already loaded, but the Intel(R) PROSet for Wireless supplicant is still
unloaded, the client sends 802.11 authentication with an Authentication algorithm value
of 0x0. Once the Intel(R) PROSet for Wireless supplicant loads, and engages the LEAP
profile, it sends 802.11 authentication with an Authentication algorithm value of 0x80.
However, the supplicant sends out 0x80 only if the Rogue AP box is checked.
Network-EAP, Open and Required EAP
AP: If Network-EAP, Open and Required EAP boxes are checked then it would accept
both types of 802.11 authentication algorithm values 0x0 and 0x80. However, once the
client is associated and authenticated the AP expects an EAP handshake to take
place. For any reason if the EAP handshake does not take place quickly, the AP would
not respond to the client for about 60 seconds.
Client: Here the client could send out an authentication algorithm value of 0x80 or 0x0.
Both values are acceptable and the 802.11 authentication handshake would succeed.
During boot, when the Wireless LAN driver is already loaded and the client sends 802.11
authentication with an Authentication algorithm value of 0x0. This is sufficient to get
authenticated but the corresponding EAP or LEAP credentials need to be communicated
to the AP to establish a connection.
Open and Required EAP only
AP: In the case where the AP is configured with Network-EAP unchecked, but Open and
Required EAP checked, the AP will reject any client attempting to 802.11 authenticate
using an authentication algorithm value of 0x80. The AP would accept any client using an
authentication algorithm value of 0x0, and expects EAP handshake to commence soon
after. In this case, the client uses MD5, TLS, LEAP or any other appropriate EAP method
suitable for the specific network configuration.
Client: The client in this case is required to send out an authentication algorithm value of
0x0. As mentioned before the sequence involves a repeat of the initial 802.11
authentication handshake. First, the Wireless LAN driver initiates authentication with a
value of 0x0 and later the supplicant would repeat the process. However, the
authentication algorithm value used by the supplicant depends status of the Rogue AP
checkbox. When the Rogue AP box is unchecked, the client sends an 802.11
authentication with Authentication algorithm value of 0x0 even after the supplicant
loads and engages the LEAP profile.
Some non-Intel clients, for example, when set to LEAP, cannot authenticate in this case.
However, the Intel Wireless LAN client can authenticate, if the Rogue AP is unchecked.
Rogue AP Checkbox configuration
When the checkbox is checked it ensures that the client implements the Rogue AP
feature as required by CCX. The client makes note of APs that it failed to authenticate
with and sends this information to the AP that allows it to authenticate and connect. Also,
the supplicant sets the Authentication algorithm type to 0x80 when the Rogue AP box is
checked. There may be some network configurations implementing and Open and
Required EAP only as described above. For this setup to work, the client must use an
Authentication Algorithm value of 0x0, as opposed to the need to use 0x80 for NetworkEAP only described above. Therefore, the Rogue AP checkbox also enables the client to
support Network-EAP only and Open and Required EAP only.

Numerical
802.11a: The 802.11a standard specifies a maximum data transfer rate of 54Mbps and
an operating frequency of 5GHz. The 802.11a standard uses the Orthogonal Frequency
Division Multiplexing (OFDM) transmission method. Additionally, the 802.11a standard
supports 802.11 features such as WEP encryption for security.
802.11b:The 802.11b standard specifies a maximum data transfer rate of 11Mbps, an
operating frequency of 2.4GHz, and WEP encryption for security. 802.11b networks are
also referred to as Wi-Fi networks.
802.11g: The 802.11g standard specifies a maximum data transfer rate of 54Mbps, an
operating frequency of 2.4GHz, and WEP encryption for security. 802.11g networks are
also referred to as Wi-Fi networks.
802.11x: A series of IEEE specifications for LANs: currently 802.11b, 802.11a, and
802.11g. Using any one of these extensions to the 802.11 standard permits wireless
communication between a client and an access point or between two clients. 802.1x is
based on the Extensible Authentication Protocol (EAP), the 802.1x standard is one of the
IEEE standards for network authentication and key management. It establishes a
framework that supports multiple authentication methods. This standard can be
incorporated into any type of network to enhance its security.
Access Point: A device that serves as a communications hub for wireless clients and
provides a connection to a wired LAN.
Advanced Encryption Standard (AES): A federal information-processing standard,
supporting 128-, 192-, and 256-bit keys.
Basic Service Set Identifier (BSSID): A unique identifier for each wireless client on a
wireless network. The BSSID is the Ethernet MAC address of each adapter on the
network.
Bit Rate: The total number of bits (ones and zeros) per second that a network
connection can support. Note that this bit rate will vary, under software control, with
different signal path conditions.
Bluetooth: An incompatible, very short-range lower speed communications system
(PAN), developed first in Europe as a "cable replacement" for printers and similar
peripheral connections. Its usage has expanded to include cordless earphones and
similar devices. It uses the 2.4 GHz ISM band, and "co-exists" with 802.11b. Here the
term, "co-exist" means that not all researchers agree on the amount of mutual
interference generated when both systems operate in the same location.
Broadcast SSID: Used to allow an access point to respond to clients on a wireless
network by sending probes.
Data Rate (Information Rate): Not all bits carry user information. Each group (packet) of
bits contains headers, trailers, echo control, destination information, and other data
required by the transmission protocol. It is important to understand the difference
between bit rate and data rate, since the overhead information may consume more than
40% of the total transmission. This difference is common to many such data systems,
including Ethernet.
Direct-Sequence Spread Spectrum (DSSS) and Frequency-Hop Spread Spectrum
(FHSS): Two incompatible technologies used in radio transmission.
Dynamic IP Address: An IP address that is automatically assigned to a client station in
a TCP/IP network, typically by a DHCP server. Network devices that serve multiple
users, such as servers and printers, are usually assigned static IP addresses.
Extensible Authentication Protocol (EAP): An IETF standard that establishes an
authentication protocol for network access. Many authentication methods, including
passwords, certificates, and smart cards, work within this framework.
EAP-TLS: A type of authentication method using the Extensible Authentication Protocol
(EAP) and a security protocol called the Transport Layer Security (TLS). EAP-TLS uses
certificates which use passwords. EAP-TLS authentication supports dynamic WEP key
management.
EAP-TTLS: A type of authentication method using the Extensible Authentication Protocol
(EAP) and Tunneled Transport Layer Security (TTLS). EAP-TTLS uses a combination of
certificates and another method, such as passwords. It is more secure than MD5
authentication, which uses passwords, and less secure than EAP-TLS authentication,
which exclusively uses certificates. EAP-TTLS authentication supports dynamic WEP key
management.
Encryption: Scrambling data so that only the authorized recipient can read it. Usually a
key is needed to decrypt the data.
Extended Service Set IDentifier (ESSID): A type of unique identifier applied to both the
AP and the wireless PC Card that is attached to each packet. This allows the AP to
recognize each wireless client and its traffic.
Firewall:A firewall is a set of related programs, located at a network gateway server, that
protects the resources of a network from users from other networks.
Frequencies: Strike a piano key and you generate a tone. Pick up the tone with a
microphone and your tone turns in to a "vibrating" or "cycling" electronic signal. The rate
of vibration depends on the key struck. In electronics we refer to this rate of vibration as
the number of "cycles per second." The formal term for this value is Hertz. As we move
up in rate, such as in the Broadcast Band, we can use Kilohertz (KHz) to represent 1,000
Hz, or Megahertz (MHz) to represent 1,000,000 Hz. Continuing much further upward, we
finally reach 1,000,000,000 Hz, which we can fortunately shorten to a Gigahertz (GHz).
These frequencies are the home of both 802.11a (5 GHz) and 802.11b (2.4 GHz).
Independent Basic Service Set Identifier (IBSSID): Used to identify a wireless network
configured to allow each wireless client to communicate directly with each other without
an access point.
Independent Network: A network that provides (usually temporarily) peer-to-peer
connectivity without relying on a complete network infrastructure.
Infrastructure Network: A wireless network centered around an access point. In this
environment, the access point not only provides communication with the wired network
but also mediates wireless network traffic in the immediate neighborhood.
Institute of Electrical and Electronics Engineers (IEEE): An organization involved in
setting computing and communications standards.
ISM Bands: A series of frequency bands, set aside by the FCC for Industrial, Scientific
and Medical applications. Users of these bands operate equipment on a shared basis,
meaning that they must expect, and accept interference from other legal users. Products
manufactured for ISM Band use must be approved by the FCC, but the user does not
have to be licensed. In addition to WLAN, ISM bands support cordless phones,
microwave ovens, baby monitors, toys, ham radio transceivers, and other wireless
services.
Kerberos: An authentication system enabling protected communication over an open
network using a unique key called a ticket.
Media Access Control (MAC) Address: A hardwired address applied at the factory. It
uniquely identifies network hardware, such as a wireless PC Card, on a LAN or WAN.
Microcell: A bounded physical space in which a number of wireless devices can
communicate. Because it is possible to have overlapping cells as well as isolated cells,
the boundaries of the cell are established by some rule or convention.
Microwave: Technically, the term describes any frequency above 1.0 GHz.
Unfortunately the advertising industry has contorted this meaning considerably. In our
discussion we will stick to the technical definition.
Multipath: The signal variation caused when radio signals take multiple paths from
transmitter to receiver.
Orthogonal Frequency Division Multiplexing (OFDM): A modulation technique for
transmitting large amounts of digital data over radio waves. 802.11a uses OFDM, as will
802.11g.
Peer-to-Peer Mode: A wireless network structure that allows wireless clients to
communicate with each other without using an access point.
Personal Area Network (PAN): A personal area network, or PAN, is a networking
scheme that enables computing devices such as PCs, laptop computers, handheld
personal computers, printers and personal digital assistants (PDAs) to communicate with
each other over short distances either with or without wires.
Preamble: A preliminary signal transmitted over a WLAN to control signal detection and
clock synchronization.
Radio Frequency (RF) Terms (GHz, MHz, Hz): The international unit for measuring
frequency is Hertz (Hz), which is equivalent to the older unit of cycles per second. One
Mega-Hertz (MHz) is one million Hertz. One Giga-Hertz (GHz) is one billion Hertz. For
reference: the standard US electrical power frequency is 60 Hz, the AM broadcast radio
frequency band is 0.55 -1.6 MHz, the FM broadcast radio frequency band is 88-108 MHz,
and microwave ovens typically operate at 2.45 GHz.
Range: The distance over which a given system can communicate.
RC4: An encryption algorithm designed at RSA Laboratories; specifically, a stream
cipher of pseudo-random bytes that is used in WEP encryption.
Remote Authentication Dial-In User Service (RADIUS): An authentication and
accounting system that verifies users' credentials and grants access to requested
resources.
Roaming: Movement of a wireless node between two microcells. Roaming usually
occurs in infrastructure networks built around multiple access points.
Service Set Identifier (SSID): Used to identify clients on a wireless network.
Shared key: An encryption key known only to the receiver and sender of data.
Site Survey: A process where you set up one transceiver in a fixed location, and then
use another unit to plot the field strength of the first unit’s transmitted signal. By moving
the transmitter around, and repeating the plots, you can develop a plan as to the best
locations for access points. You will also identify dead zones and other areas in need of
special attention. This can be a long, slow process, but it beats ripping up an
unsatisfactory installation and starting over. These tests require special software
commands. Refer to your manual for specific instructions. If you have a very large, or
unusually complex installation situation, you might want to consider calling in
professionals to do your survey. We are not permitted to suggest installer names, but you
can check your yellow pages or similar sources for likely candidates.
Static IP Address: A permanent IP address that is assigned to a node in a TCP/IP
network.
Transmission Control Protocol (TCP): A method (protocol) used with the IP (Internet
Protocol) to send data in the form of message units between network devices over a LAN
or WAN. The IP carries the delivery of the data (routing), and TCP keeps track of the
individual units of data (called packets) that a message is divided into for delivery over
the network.
Transmission Control Protocol/Internet Protocol (TCP/IP): The basic communication
language or set of protocols for communications over a network (developed specifically
for the Internet). TCP/IP defines a suite or group of protocols and not only TCP and IP.
Transceiver: A commonly used term that describes a combination transmitter and
receiver. Both 802.11a and 802.11b devices would be properly described as data
transceivers.
UNII Bands: Unlicensed National Information Infrastructure. In contrast to the ISM
bands, these are a group of frequency bands set aside by the FCC for WLAN type
communications only. Users must accept interference from other legal WLAN users, but
the other sources of interference problems are, or legally should be, missing.
WEP64 and WEP128: Wired Equivalent Privacy, 64 bit and 128 bit (64 bit is sometimes
referred to as 40 bit). This is a low-level encryption technique designed to give the user
about the same amount of privacy that he would expect from a LAN. It is extremely
important to understand that WEP is not some CIA-proof supercode! It performs as
intended, giving the user a simple level of data security and protection from casual
electronic eavesdropping. Use of the 128 bit option at all possible times is recommended.
Remember that 802.11 devices transmit (broadcast) in all directions, and that it is
possible, with very complex software, to copy and decode WEP transmissions. The task
is not trivial, but it is possible. If your data is extremely sensitive, you should consider
some form of secondary protection, such as strong passwords and an additional level of
encryption. Suitable software packages are available from reputable suppliers. Although
not intended by the original architects, WEP also helps prevents unauthorized access to
your system by an outsider. Hackers have been known to access systems from outside a
building, and to then to access the Web for a leisurely session, all at the system owner’s
expense.
Wide Area Network (WAN): A wide area network (WAN) is a voice, data, or video
network that provides connections from one or more computers or networks within a
business to one or more computers or networks that are external to such business.
Wireless: A microwave transceiver system.
Wireless LAN (WLAN): Wireless LAN is a type of local-area network that uses highfrequency radio waves rather than wires to communicate between nodes. WLAN is a
flexible data communication system used as an alternative to, or an extension of a wired
LAN.
Wireless Node: A user computer with a wireless network interface card (adapter).
