Chapter 8 Routine Procedures
Inserting and Removing a Client Adapter
Inserting and Removing a Client Adapter
This section provides instructions for inserting and removing PC cards, PC-Cardbus cards, and PCI
cards. Instructions are not provided for LM cards and mini PCI cards because they are pre-installed
inside computing devices and are not meant to be installed or removed by the user.
Caution These procedures and the physical connections they describe apply generally to
conventional PC card slots, Cardbus slots, and PCI expansion slots. In cases of custom or
nonconventional equipment, be alert to possible differences in PC card slot, Cardbus slot,
and PCI expansion slot configurations.
Inserting a Client Adapter
Follow the instructions in one of the sections below to insert a PC card, PC-Cardbus card, or PCI card
into a computing device.
Inserting a PC Card or PC-Cardbus Card
Step 1 Before you begin, examine the card. One end has a dual-row, 68-pin connector. The card is keyed so it
can be inserted only one way into the PC card slot or Cardbus slot.
Note The PC card slot or Cardbus slot is on the left or right side of the computer,
depending on the model.
Step 2 Follow the instructions below for your specific operating system:
•Windows 95, Windows 98, Windows 2000, Windows Me, or Windows XP– Turn on your
computer, let the operating system boot up completely, and follow the remaining steps in this section
to insert the card.
•Windows NT – Turn off your computer, follow the remaining steps in this section to insert the card,
and reboot your computer.
Caution Do not force the card into your computer’s PC card slot or Cardbus slot. Forcing it will
damage both the card and the slot. If the card does not insert easily, remove the card and
reinsert it.
Step 3 Hold the card with the Cisco logo facing up and insert it into the PC card slot or Cardbus slot, applying
just enough pressure to make sure it is fully seated (see Figure 8-1).

Step 4 Go to the “Installing the Driver” section on page 3-3 to install the driver for your computer’s operating
system.
Inserting a PCI Card
Step 1 Turn off the PC and all its components.
Step 2 Remove the computer cover.
Note On most Pentium PCs, PCI expansion slots are white. Refer to your PC
documentation for slot identification.
Step 3 Remove the screw from the top of the CPU back panel above an empty PCI expansion slot. This screw
holds the metal bracket on the back panel.
Caution Static electricity can damage your PCI card. Before removing the adapter from the
anti-static packaging, discharge static by touching a metal part of a grounded PC.
Step 4 Examine the PCI card. The antenna connector and the LEDs face out of your computer and are visible
when you put the cover back on. The bottom edge of the card is the connector you will insert into an
empty expansion slot in your computer. See Figure 8-2.

Step 5 Tilt the card to allow the antenna connector and LEDs to slip through the opening in the CPU back panel.
Step 6 Press the card into the empty slot until the connector is firmly seated.
Caution Do not force the card into the expansion slot as this could damage both the card and the
slot. If the card does not insert easily, remove it and reinsert it.
Step 7 Reinstall the screw on the CPU back panel and replace the computer cover.
Step 8 Attach the 2-dBi antenna to the card’s antenna connector until it is finger-tight. Do not overtighten.
Step 9 For optimal reception, position the antenna so it is straight up.
Step 10 Boot up your PC.
Removing a Client Adapter
Follow the instructions in one of the sections below to remove a PC card, PC-Cardbus card, or PCI card
from a computing device, when necessary.
Removing a PC Card or PC-Cardbus Card
To remove a PC card or PC-Cardbus card after it is successfully installed and configured (such as when
your laptop is to be transported), completely shut down your computer and pull the card directly out of
the PC card slot or Cardbus slot. When the card is reinserted and the computer is rebooted, your
connection to the network should be re-established.
Removing a PCI Card
Because PCI client adapters are installed inside desktop computers, which are not designed for portable
use, you should have little reason to remove the adapter. However, instructions are provided below in
case you ever need to remove your PCI card.
Step 1 Completely shut down your computer.
Step 2 Disconnect the client adapter’s antenna.
Step 3 Remove the computer cover.
Step 4 Remove the screw from the top of the CPU back panel above the PCI expansion slot that holds your client
adapter.
Step 5 Pull up firmly on the client adapter to release it from the slot and carefully tilt the adapter to allow it to
clear the opening in the CPU back panel.
Step 6 Reinstall the screw on the CPU back panel and replace the computer cover.

Chapter 8 Routine Procedures Upgrading the Firmware
Upgrading the Firmware
The client adapter is shipped with the firmware installed in its Flash memory; however, a more recent
version of the firmware may be available from Cisco.com. Cisco recommends using the most current
version of radio firmware. Follow the instructions in this section to determine the version of your client
adapter’s firmware and to upgrade it if a more recent version is available from Cisco.com.

Chapter 8 Routine Procedures Restarting the Client Adapter
Deleting the ACU Icon from the Desktop
An ACU icon is automatically added to the desktop when you install ACU, provided you selected this
option during installation. If you wish to remove this icon from your desktop, right-click the icon, click
Delete, and click Yes to confirm your decision.
Restarting the Client Adapter
ACU enables you to re-initialize (or restart) the client adapter without having to reboot your computer
or eject and reinsert the adapter. For instance, if your client adapter is experiencing poor throughput, you
might want to restart the client adapter to try to force it to disassociate from the access point to which it
is currently associated in the hope that it will reassociate to an access point with a stronger signal.
Note Restarting the client adapter may cause you to lose your wireless network connection.
Follow the steps below to restart the client adapter.
Step 1 Open ACU.
Step 2 Select the Restart Card option from the Commands drop-down menu (see Figure 8-4).
Step 3 When prompted to confirm your decision, click Yes. The driver stops the client adapter’s radio, writes
the configuration (although no parameter settings have been changed), and restarts the radio. The status
bar at the bottom of the ACU screen shows the client adapter losing association and then reassociating.
Turning Your Client Adapter’s Radio On or Off
Your client adapter’s radio can be turned on or off. Turning the radio off prevents the adapter from
transmitting RF energy. You might want to turn off the client adapter’s radio when you are not
transmitting data and want to conserve battery power or when you are using a laptop on an airplane and
want to prevent the adapter’s transmissions from potentially interfering with the operation of certain
devices.
When the radio is on, it periodically sends out beacons even if it is not associated to an access point, as
required by the 802.11 specification. Therefore, it is important to turn it off around devices that are
susceptible to RF interference.
Note Your client adapter is not associated while the radio is off.
Follow the instructions below to turn the client adapter’s radio on or off.
•If your client adapter’s radio is on, opening ACU and selecting Radio Off from the Commands
drop-down menu (see Figure 8-4) turns the radio off. The status bar at the bottom of the ACU screen
indicates that the radio is turned off.
•If your client adapter’s radio is off, opening ACU and selecting Radio On from the Commands
drop-down menu (see Figure 8-4) turns the radio on.

Client Adapter Recognition Problems
Note This section does not apply to mini PCI cards.
If your client adapter is not being recognized by your computer’s PCMCIA adapter, check your
computer’s BIOS and make sure that the PC card controller mode is set to PCIC compatible.
Note A computer’s BIOS varies depending on the manufacturer. For support on BIOS-related
issues, consult your computer’s manufacturer.
Resolving Resource Conflicts
Note This section does not apply to the mini PCI cards.
If you encounter problems while installing your client adapter on a computer running a Windows
operating system, you may need to specify a different interrupt request (IRQ) or I/O range for the
adapter.
The default IRQ for the client adapter is IRQ 10, which may not work for all systems. Follow the steps
for your specific operating system to obtain an available IRQ.
During installation the adapter’s driver installation script scans for an unused I/O range. The installation
can fail if the I/O range found by the driver installation script is occupied by another device but not
reported by Windows. An I/O range might not be reported if a device is physically present in the system
but not enabled under Windows. Follow the steps for your specific operating system to obtain an
available I/O range.

Problems Associating to an Access Point
Follow the instructions below if your client adapter fails to associate to an access point.
•If possible, move your workstation a few feet closer to an access point and try again.
•Make sure the client adapter is securely inserted in your computer’s client adapter slot.
•If you are using a PCI client adapter, make sure the antenna is securely attached.
•Make sure the access point is turned on and operating.
•Check that all parameters are set properly for both the client adapter and the access point. These
include the SSID, EAP authentication, WEP activation, network type, channel, etc.

Chapter9 Troubleshooting
Troubleshooting the Client Adapter
•Follow the instructions in the previous section to resolve any resource conflicts. If you are using
Windows NT, you may also want to try disabling the Ethernet port.
•If the client adapter still fails to establish contact, refer to the “Obtaining Technical Assistance”
section in the Preface for technical support information.
Problems Authenticating to an Access Point
If your client adapter is a 40-bit card and LEAP or EAP is enabled, the adapter can associate to but not
authenticate to access points using 128-bit encryption. To authenticate to an access point using 128-bit
encryption, you have two options:
•Purchase a 128-bit client adapter. This is the most secure option.
•Disable static WEP for the client adapter and configure the adapter and the access point to associate
to mixed cells. This option presents a security risk because your data is not encrypted as it is sent
over the RF network.
Problems Connecting to the Network
After you have installed the appropriate driver and client utilities, contact your IS department if you have
a problem connecting to the network. Proxy server, network protocols, and further authentication
information might be needed to connect to the network.
Losing Association Upon Resuming from Suspend Mode
(Windows NT and Mini PCI Card Only)
Because Windows NT does not support resuming of mini PCI cards, your client adapter loses its
association to an access point upon resuming from suspend mode. If this occurs, restart your client
adapter to reassociate.
Parameters Missing from ACU Properties Screens
If some parameters are grayed out on the ACU Properties screens, your system administrator may have
used an auto installer to deactivate these parameters. In this case, these parameters are not available for
you to set.

Appendix E Configuring the Client Adapter through Windows XP
Overview
Overview
This chapter provides instructions for minimally configuring the client adapter through Windows XP
(instead of through ACU) as well as for enabling one of the three security options that are available for
use with this operating system. The “Overview of Security Features” section below describes each of
these options so that you can make an informed decision before you begin the configuration process.
In addition, the chapter also provides basic information on using Windows XP to specify the networks
to which the client adapter associates and to view the current status of your client adapter.
Note If you require more information about configuring or using your client adapter with Windows XP,
refer to Microsoft’s documentation for Windows XP.
Overview of Security Features
When you use your client adapter with Windows XP, you can protect your data as it is transmitted
through your wireless network by encrypting it through the use of Wired Equivalent Privacy (WEP)
encryption keys. With WEP encryption, the transmitting device encrypts each packet with a WEP key,
and the receiving device uses that same key to decrypt each packet.
The WEP keys used to encrypt and decrypt transmitted data can be statically associated with your
adapter or dynamically created as part of the EAP authentication process. The information in the “Static
WEP Keys” and “EAP (with Static or Dynamic WEP Keys)” sections below can help you to decide
which type of WEP keys you want to use. Dynamic WEP keys with EAP offer a higher degree of security
than static WEP keys.
WEP keys, whether static or dynamic, are either 40 or 128 bits in length. 128-bit WEP keys offer a greater
level of security than 40-bit WEP keys.
Static WEP Keys
Each device within your wireless network can be assigned up to four static WEP keys. If a device
receives a packet that is not encrypted with the appropriate key (as the WEP keys of all devices that are
to communicate with each other must match), the device discards the packet and never delivers it to the
intended receiver.
Static WEP keys are write-only and temporary; therefore, they cannot be read back from the client
adapter and they are lost when power to the adapter is removed or the Windows device is rebooted.
Although the keys are temporary, you do not need to re-enter them each time the client adapter is inserted
or the Windows device is rebooted. This is because the keys are stored (in an encrypted format for
security reasons) in the registry of the Windows device. When the driver loads and reads the client
adapter’s registry parameters, it also finds the static WEP keys, unencrypts them, and stores them in
volatile memory on the adapter.
EAP (with Static or Dynamic WEP Keys)
The new standard for wireless LAN security, as defined by the Institute of Electrical and Electronics
Engineers (IEEE), is called 802.1X for 802.11, or simply 802.1X. An access point that supports 802.1X
and its protocol, Extensible Authentication Protocol (EAP), acts as the interface between a wireless
client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS)
server, to which the access point communicates over the wired network.

Appendix E Configuring the Client Adapter through Windows XP Overview
Two 802.1X authentication types are available when configuring your client adapter through
Windows XP:
•EAP-TLS – This authentication type is enabled through the operating system and uses a dynamic,
session-based WEP key, which is derived from the client adapter and RADIUS server, to encrypt
data.
RADIUS servers that support EAP-TLS include Cisco Secure ACS version 3.0 and greater and
Cisco Access Registrar version 1.8 and greater.
Note EAP-TLS requires the use of a certificate. Refer to Microsoft’s documentation for
information on downloading and installing the certificate.
•EAP-MD5 – This authentication type is enabled through the operating system and uses static WEP
to encrypt data. EAP-MD5 requires you to enter a separate EAP username and password (in addition
to your standard Windows network login) in order to start the EAP authentication process and gain
access to the network.
Note If you want to authenticate without encrypting the data that is transmitted over your
network, you can use EAP-MD5 without static WEP.
RADIUS servers that support EAP-MD5 include Cisco Secure ACS version 3.0 and greater and
Cisco Access Registrar version 1.8 and greater.
When you enable Require EAP on your access point and configure your client adapter for EAP-TLS or
EAP-MD5 using Windows XP, authentication to the network occurs in the following sequence:
1. The client adapter associates to an access point and begins the authentication process.
Note The client does not gain access to the network until mutual authentication between the
client and the RADIUS server is successful.
2. Communicating through the access point, the client and RADIUS server complete a mutual
authentication process, with the password (for EAP-MD5) or certificate (for EAP-TLS) being the
shared secret for authentication. The password or certificate is never transmitted during the process.
Note The authentication process is now complete for EAP-MD5. For EAP-TLS, the process
continues.
3. If mutual authentication is successful, the client and RADIUS server derive a dynamic,
session-based WEP key that is unique to the client.
4. The RADIUS server transmits the key to the access point using a secure channel on the wired LAN.
5. For the length of a session, or time period, the access point and the client use this key to encrypt or
decrypt all unicast packets that travel between them.
Note Refer to the IEEE 802.11 Standard for more information on 802.1X authentication and to the
following URL for additional information on RADIUS servers:

Note If you installed ACU but intend to use Windows XP to configure the client adapter, open
ACU and make sure the Allow Windows To Configure My Wireless Network Settings
option is selected on the Profile Manager screen.
Note These instructions assume you are using Windows XP’s classic view rather than its category
view.
Step 1 Make sure the client adapter’s driver has been installed and the client adapter is inserted into the
Windows XP device.
Step 2 Double-click My Computer, Control Panel, and Network Connections.
Step 3 Right-click Wireless Network Connection.
Step 4 Click Properties. The Wireless Network Connection Properties screen appears.
Step 5 Select the Wireless Networks tab. The following screen appears (see Figure E-1).

Step 6 Make sure that the Use Windows to configure my wireless network settings checkbox is selected.
Step 7 Select the SSID of the access point to which you want the client adapter to associate from the list of
available networks and click Configure. If the SSID of the access point you want to use is not listed or
you are planning to operate the client adapter in an ad hoc network (a computer-to-computer network
without access points), click Add.
Note The Allow Broadcast SSID to Associate option on the access point must be enabled for the
SSID to appear in the list of available networks.
The Wireless Network Properties screen appears (see Figure E-2).
Figure E-2 Wireless Network Properties Screen
Step 8 Perform one of the following:
•If you selected an SSID from the list of available networks, make sure the SSID appears in the
Network name (SSID) field.
•If you clicked Add, enter the case-sensitive SSID of the access point to which you want the client
adapter to associate or the name of the ad hoc network in the Network name (SSID) field.
Step 9 Select the Data encryption (WEP enabled) checkbox if you are planning to use static or dynamic WEP.

Appendix E Configuring the Client Adapter through Windows XP
Configuring the Client Adapter
Step 10 Select the Network Authentication (Shared mode) checkbox if you want to use shared key, rather than
open, authentication with the access point.
Open authentication allows your client adapter, regardless of its WEP settings, to authenticate and
attempt to communicate with an access point.
Shared key authentication allows your client adapter to communicate only with access points that have
the same WEP key. Cisco recommends that shared key authentication not be used because it presents a
security risk.
Note If you are planning to use EAP-TLS authentication, do not select this checkbox. EAP-TLS
does not work with shared key authentication because shared key authentication requires the
use of a WEP key, and a WEP key is not set for EAP-TLS until after the completion of EAP
authentication.
Step 11 Follow the steps below to enter up to four WEP keys, if you are planning to use static WEP.
Note If you are planning to use EAP-TLS authentication, which uses dynamic WEP, go to Step 12.
a. Obtain the WEP key for the access point (in an infrastructure network) or other clients (in an ad hoc
network) from your system administrator and enter it in the Network key field. In order to
communicate, the client adapter must use the same WEP key as the access point or other clients.
b. Select one of the following WEP key formats:
–
ASCII characters – Specifies that the WEP key will be entered in ASCII text, which includes
alpha characters, numbers, and punctuation marks.
–
Hexadecimal digits – Specifies that the WEP key will be entered in hexadecimal characters,
which include 0-9, A-F, and a-f.
c. Select one of the following WEP key lengths:
–
104 bits (13 characters/26 digits) – You can select this option (or the 40 bits option) if your
client adapter supports 128-bit WEP.
–
40 bits (5 characters/10 digits) – You must select this option if your client adapter supports
only 40-bit WEP.
d. In the Key index (advanced) field, select the number of the WEP key you are creating (0, 1, 2, or 3).
Note The WEP key must be assigned to the same number on both the client adapter and the
access point (in an infrastructure network) or other clients (in an ad hoc network).
e. Repeat the previous steps if you want to enter another WEP key.
Step 12 Select the The key is provided for me automatically checkbox if you are planning to use EAP-TLS,
which uses dynamic WEP keys.
Step 13 Select the This is a computer-to-computer (ad hoc mode) network; wireless access points are not
used checkbox if you are planning to operate the client adapter in an ad hoc network.

Appendix F Performing a Site Survey
Overview
Overview
Note This appendix applies only to people who are responsible for conducting a site survey to determine
the best placement of infrastructure devices within a wireless network.
ACU’s site survey tool can assist you in conducting a site survey. The tool operates at the RF level and
is used to determine the best placement and coverage (overlap) for your network’s infrastructure devices.
During a site survey, the current status of the network is read from the client adapter and displayed four
times per second so you can accurately gauge network performance. The feedback that you receive can
help you to eliminate areas of low RF signal levels that can result in a loss of connection between the
client adapter and its associated access point (or other infrastructure device).
The site survey tool can be operated in two modes:
•Passive Mode – This is the default site survey mode. It does not initiate any RF network traffic; it
simply listens to the traffic that the client adapter hears and displays the results. Follow the
instructions in the “Using Passive Mode” section on page F-3 to activate the passive mode.
•Active Mode – This mode causes the client adapter to actively send or receive low-level RF packets
to or from its associated access point and provides information on the success rate. It also enables
you to set parameters governing how the site survey is performed (such as the data rate). Follow the
instructions in the “Using Active Mode” section on page F-7 to activate the active mode.
Guidelines
Keep the following guidelines in mind when preparing to perform a site survey:
•Perform the site survey when the RF link is functioning with all other systems and noise sources
operational.
•Execute the site survey entirely from the mobile station.
•When using the active mode, conduct the site survey with all variables set to operational values.
Additional Information
Also consider the following operating and environmental conditions when performing a site survey:
•Data rates – Sensitivity and range are inversely proportional to data bit rates. Therefore, the
maximum radio range is achieved at the lowest workable data rate, and a decrease in receiver
threshold sensitivity occurs as the radio data increases.
•Antenna type and placement – Proper antenna configuration is a critical factor in maximizing
radio range. As a general rule, range increases in proportion to antenna height.
•Physical environment – Clear or open areas provide better radio range than closed or filled areas.
Also, the less cluttered the work environment, the greater the range.

OL-1394-03
Appendix F Performing a Site Survey Specifying Signal Strength Units
•Obstructions – A physical obstruction such as metal shelving or a steel pillar can hinder the
performance of wireless devices. Avoid placing these devices in a location where a metal barrier is
between the sending and receiving antennas.
•Building materials – Radio penetration is greatly influenced by the building material used in
construction. For example, drywall construction allows greater range than concrete blocks, and
metal or steel construction is a barrier to radio signals.
Note Refer to the Hardware Installation Guide for your infrastructure device for additional information on
factors affecting placement.
Specifying Signal Strength Units
Follow the steps below to specify how signal strength units are displayed on the site survey screens.
Step 1 Double-click the Aironet Client Utility (ACU) icon on your desktop to open ACU.
Step 2 Click the Preferences icon or select Preferences from the Options drop-down menu. The Aironet Client
Utility Preferences screen appears.
Step 3 Under Signal Strength Display Units, select one of the following options:
•Percent – Displays the signal strength as a percentage.
•dBm – Displays the signal strength in decibels with respect to milliwatts.
Note dBm can be selected only if your client adapter is using PCM/LMC/PCI card firmware
version 3.92 or greater, mini PCI card firmware version 5.0 or greater, or PC-Cardbus
firmware version 4.99 or greater.
Step 4 Click OK to save your changes.
Using Passive Mode
Step 1 Open ACU; then click the Site Survey icon or select Site Survey from the Commands drop-down menu.
The Site Survey - Passive Mode screen appears, provided a client adapter is installed in the Windows
device and is running.
Figure F-1 shows the Site Survey - Passive Mode screen with the signal strength values displayed as

Appendix F Performing a Site Survey
Forcing the Client Adapter To Reassociate
Forcing the Client Adapter To Reassociate
The client adapter will attempt to maintain its association to an access point for as long as it can.
Therefore if you are on a fringe area while conducting a site survey, you may want to reinitialize (or
restart) the client adapter in an attempt to force it to disassociate from the access point to which it is
currently associated and reassociate to another access point.
Note Restarting the client adapter may cause you to lose your wireless network connection.
Follow the steps below to attempt to force the client adapter to disassociate from its current access point
and reassociate to another during a site survey.
Step 1 Click the Restart Card button on the bottom of the Site Survey screen.
Step 2 When prompted to confirm your decision, click Yes. The driver stops the client adapter’s radio, writes
the configuration (although no parameter settings have been changed), and restarts the radio.

GLOSSARY
802.1X Also called 802.1X for 802.11. 802.1X is the new standard for wireless LAN security, as defined by the
Institute of Electrical and Electronics Engineers (IEEE). An access point that supports 802.1X and its
protocol, Extensible Authentication Protocol (EAP), acts as the interface between a wireless client and an
authentication server, such as a Remote Authentication Dial-In User Service (RADIUS) server, to which the
access point communicates over the wired network.
802.11 The IEEE standard that specifies carrier sense media access control and physical layer specifications
for 1- and 2-megabit-per-second (Mbps) 2.4-GHz wireless LANs.
802.11a The IEEE standard that governs the deployment of 5-GHz OFDM systems. It specifies the
implementation of the physical layer for wireless UNII bands (see UNII, UNII 1, and UNII 2) and
provides four channels per 100 MHz of bandwidth.
802.11b The IEEE standard that specifies carrier sense media access control and physical layer specifications
for 5.5- and 11-Mbps 2.4-GHz wireless LANs.
A
Access Point A wireless LAN data transceiver that uses radio waves to connect a wired network with wireless
stations.
Ad Hoc Network A wireless network composed of stations without access points.
Alphanumeric A set of characters that contains both letters and numbers.
Associated A station is configured properly to allow it to wirelessly communicate with an access point.
B
Bandwidth Specifies the amount of the frequency spectrum that is usable for data transfer. It identifies the
maximum data rate that a signal can attain on the medium without encountering significant power loss.
BPSK Binary phase shift keying. A modulation technique used by IEEE 802.11-compliant wireless LANs for
transmission at 1 Mbps.
Broadcast key
rotation A security feature for use with dynamic WEP keys. If your client adapter uses LEAP or EAP-TLS
authentication and you enable this feature, the access point changes the dynamic broadcast WEP key
that it provides at the interval you select.

D
Data Rates The range of data transmission rates supported by a device. Data rates are measured in megabits per
second (Mbps).
dBi A ratio of decibels to an isotropic antenna that is commonly used to measure antenna gain. The greater
the dBi value, the higher the gain and the more acute the angle of coverage.
DHCP Dynamic Host Configuration Protocol. A protocol available with many operating systems that
automatically issues IP addresses within a specified range to devices on the network. The device retains
the assigned address for a specific administrator-defined period.
Dipole A type of low-gain (2.2-dBi) antenna consisting of two (often internal) elements.
DSSS Direct-sequence spread spectrum. A type of spread spectrum radio transmission that spreads its signal
continuously over a wide frequency band.
Duplicate Packets Packets that were received twice because an acknowledgement got lost and the sender retransmitted the
packet.
E
EAP Extensible Authentication Protocol. EAP is the protocol for the optional IEEE 802.1X wireless LAN
security feature. An access point that supports 802.1X and EAP acts as the interface between a wireless
client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS) server,
to which the access point communicates over the wired network.
Ethernet The most widely used wired local area network. Ethernet uses carrier sense multiple access (CSMA)
to allow computers to share a network and operates at 10, 100, or 1000 megabits per second (Mbps),
depending on the physical layer used.

L
LEAP LEAP, or EAP-Cisco Wireless, is the 802.1X authentication type that is available for use with operating
systems that do not have built-in EAP support. Support for LEAP is provided in the client adapter’s
firmware and the Cisco software that supports it, rather than in the operating system. With LEAP, a
username and password are used by the client adapter to perform mutual authentication with the
RADIUS server through an access point.
M
MAC Address The Media Access Control (MAC) address is a unique serial number assigned to a networking device
by the manufacturer.
MIC Message integrity check. MIC prevents bit-flip attacks on encrypted packets. During a bit-flip attack,
an intruder intercepts an encrypted message, alters it slightly, and retransmits it, and the receiver
accepts the retransmitted message as legitimate. The client adapter’s driver and firmware must support
MIC functionality, and MIC must be enabled on the access point.
Modulation Any of several techniques for combining user information with a transmitter’s carrier signal.
Multicast Packets Packets transmitted to multiple stations.
Multipath The echoes created as a radio signal bounces off of physical objects.
O

spread spectrum devices limits the types of antennas that may be used with transmission equipment. In
compliance with this rule, Cisco Aironet, like all other wireless LAN providers, equips its radios and
antennas with a unique connector to prevent attachment of non-approved antennas to radios.
RTS Threshold The packet size at which an access point will issue a request to send (RTS) before sending the packet.
S
Spread Spectrum A radio transmission technology that spreads the user information over a much wider bandwidth than
otherwise required in order to gain benefits such as improved interference tolerance and unlicensed
operation.
SSID Service set identifier. A unique identifier that stations must use to be able to communicate with an
access point. The SSID can be any alphanumeric entry up to a maximum of 32 characters.
T
TKIP Temporal Key Integrity Protocol. Also referred to as WEP key hashing. A security feature that defends
against an attack on WEP in which the intruder uses the initialization vector (IV) in encrypted packets
to calculate the WEP key. TKIP removes the predictability that an intruder relies on to determine the
WEP key by exploiting IVs.
