IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY. The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense. The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Ciscos installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. Modifying the equipment without Ciscos written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense. You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
Turn the television or radio antenna until the interference stops.
Move the equipment to one side or the other of the television or radio.
Move the equipment farther away from the television or radio.
Plug the equipment into an outlet that is on a different circuit from the television or radio.

Two levels of support are available: the Cisco TAC Web Site and the Cisco TAC Escalation Center. Cisco TAC inquiries are categorized according to the urgency of the issue:
Priority level 4 (P4)You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
Priority level 3 (P3)Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
Priority level 2 (P2)Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
Priority level 1 (P1)Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available. The Cisco TAC resource that you choose is based on the priority of the problem and the conditions of service contracts, when applicable. Cisco TAC Web Site You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to this URL:

The client adapters are fully compatible when used in devices supporting Plug-and-Play (PnP) technology. The primary function of the client adapters is to transfer data packets transparently through the wireless infrastructure through an access point connected to a wired LAN. The adapters operate similarly to a standard network product except that the cable is replaced with a radio connection and an access point is required to make the connection to the wire. No special wireless networking functions are required, and all existing applications that operate over a network can operate using the adapters. This document covers the five client adapters described in Table 1-1.

If the last two product model numbers contain K9, the card is 128-bit WEP capable. Terminology The following terms are used throughout this document:
client adapter Refers to all five types of adapters.
PC card, LM card, PCI card, mini PCI card, or PC-Cardbus card Refers to a specific adapter.
workstation (or station) Refers to a computing device with an installed client adapter.
infrastructure device Refers to a device that connects client adapters to a wired LAN, such as an access point, bridge, or base station. Throughout this document, access point is used to represent infrastructure devices in general. Hardware Components The client adapter has three major hardware components: a radio, a radio antenna, and two LEDs. Radio Different radios are used for the 2.4-GHz and 5-GHz client adapters:
The Cisco Aironet 340 and 350 series PC, LM, PCI, and mini PCI cards are IEEE 802.11b-compliant client adapters. They contain a direct-sequence spread spectrum (DSSS) radio that operates in the 2.4-GHz Industrial Scientific Medical (ISM) license-free band. The 340 series 30-milliwatt (mW) radio and the 350 series 100-mW radio transmit data over a half-duplex radio channel operating at up to 11 Mbps. These cards interoperate with other IEEE 802.11b-compliant client devices in ad hoc
(or peer-to-peer) mode or with Cisco Aironet 340, 350, and 1200 Series Access Points (with a 2.4-GHz radio) and other IEEE 802.11b-compliant infrastructure devices in infrastructure mode. They are approved for indoor and outdoor use. DSSS technology distributes a radio signal over a wide range of frequencies and then returns the signal to the original frequency range at the receiver. The benefit of this technology is its ability to protect the data transmission from interference. For example, if a particular frequency encounters noise or interference or both, enough redundancy is built into the signal on other frequencies that the client adapter usually will still be successful in its transmission.
The Cisco Aironet AIR-CB20A PC-Cardbus card is an IEEE 802.11a-compliant client adapter. It contains an orthogonal frequency division multiplexing (OFDM) radio that operates in the Unlicensed National Information Infrastructure (UNII) 1 and UNII 2 license-free bands located in the lower 5-GHz portion of the radio frequency spectrum. The 20-mW radio transmits data over a half-duplex radio channel operating at up to 54 Mbps. This card interoperates with other IEEE 802.11a-compliant client devices in ad hoc mode or with Cisco Aironet 1200 Series Access Points
(with a 5-GHz radio) and other IEEE 802.11a-compliant infrastructure devices in infrastructure mode. It is approved for indoor use only, except in the United States which allows for outdoor use on channels 52 through 64. OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 1-3 B E TA D R A F T - C I S C O C O N F I D E N T I A L Chapter 1 Product Overview Hardware Components Radio Antenna The type of antenna used depends on your client adapter:
PC cards have an integrated, permanently attached diversity antenna. The benefit of the diversity antenna system is improved coverage. The system works by allowing the card to switch and sample between its two antenna ports in order to select the optimum port for receiving data packets. As a result, the card has a better chance of maintaining the radio frequency (RF) connection in areas of interference. The antenna is housed within the section of the card that hangs out of the PC card slot when the card is installed.
LM cards are shipped without an antenna; however, an antenna can be connected through the cards external connector.
PCI cards are shipped with a 2-dBi dipole antenna that attaches to the cards antenna connector. However, other types of antennas may be used. PCI cards can be operated through the primary (or right) antenna port only.
Mini PCI cards are designed to be used with either one or two antennas, which connect to the cards two antenna connectors. If two antennas are used, the radio automatically selects the antenna that presents the best RF signal. If only one antenna is used, the radio finds and uses it regardless of which connector it is plugged into.
PC-Cardbus cards have an integrated, permanently attached non-diversity antenna that contains two antenna ports, one for transmitting and one for receiving. The card cannot switch and sample between the ports. The antenna is housed within the section of the card that hangs out of the Cardbus slot when the card is installed. Note Refer to the Antenna Mode (Transmit and Receive) parameters in Table 5-4 and Table 5-5 for information on setting the client adapters antenna mode. Note External antennas used in combination with a power setting resulting in a radiated power level above 100 mW equivalent isotropic radiated power (EIRP) are not allowed for use within the European community and other countries that have adopted the European R&TTE directive or the CEPT recommendation Rec 70.03 or both. For more details on legal combinations of power levels and antennas in those countries, refer to the Declaration of Conformity with Regard to the R&TTE Directive 1999/5/EC section on page C-4 and the Maximum Power Levels and Antenna Gains section on page D-4. LEDs The client adapters have two LEDs that glow or blink to indicate the status of the adapter or to convey error messages. Refer to Chapter 9 for an interpretation of the LED codes. Note Mini PCI cards do not have LEDs.

Radio Firmware The firmware, which is contained in the client adapters Flash memory, controls the adapters radio. The client adapter is shipped with the firmware installed; however, a more recent version of the firmware may be available from Cisco.com. Note Cisco recommends using the most current version of radio firmware. Chapter 8 provides instructions for determining the version of your client adapters firmware and upgrading it if necessary. Driver The driver provides an interface between a computer running a Windows operating system and the client adapter, thereby enabling Windows and the applications it runs to communicate with the adapter. The driver is provided on the CD that shipped with the client adapter and must be installed before the adapter can be used. Chapter 3 provides instructions for installing the driver. Note The CD has the latest version of the driver available at the time of pressing; however, a more recent version of the driver may be available from Cisco.com. Cisco recommends installing the most current version of the driver. Chapter 3 provides instructions for installing the driver from either location. Client Utility Note Note The client utility, which is entitled Aironet Client Utility (ACU), is an optional application that interacts with the radio firmware to adjust client adapter settings and display information about the adapter. ACU is provided on the CD that shipped with the client adapter. If you plan to use ACU, it should be installed before the adapter is used. Chapter 3 provides instructions for installing ACU. The CD has the latest version of ACU available at the time of pressing; however, a more recent version of ACU may be available from Cisco.com. Cisco recommends installing the most current version of ACU. Chapter 3 provides instructions for installing ACU from either location. If your computer is running Windows XP, you can configure your client adapter through the Windows operating system instead of through ACU. Refer to Appendix E for information. However, ACU is recommended for configuring the client adapter.

In some configurations, access points provide connections to your network or act as repeaters to increase wireless communication range. The maximum communication range is based on how you configure your wireless network. This section describes and illustrates the two most common network configurations:
Ad hoc wireless local area network (LAN)
Wireless infrastructure with workstations accessing a wired LAN For examples of more complex network configurations involving client adapters and access points, refer to the Cisco Aironet Access Point Hardware Installation Guide. Note Refer to Chapter 5 for information on setting the client adapters network mode. OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 1-7 Network Configurations Using the Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Chapter 1 Product Overview Ad Hoc Wireless LAN An ad hoc (or peer-to-peer) wireless LAN (see Figure 1-2) is the simplest wireless LAN configuration. In a wireless LAN using an ad hoc network configuration, all devices equipped with a client adapter can be linked together and communicate directly with each other. Figure 1-2 Ad Hoc Wireless LAN 0 2 5 7 4 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 1-8 OL-1394-03 Chapter 1 Product Overview B E TA D R A F T - C I S C O C O N F I D E N T I A L Network Configurations Using the Client Adapter Wireless Infrastructure with Workstations Accessing a Wired LAN A microcellular network can be created by placing two or more access points on a LAN. Figure 1-3 shows a microcellular network with workstations accessing a wired LAN through several access points. This configuration is useful with portable or mobile stations because it allows them to be directly connected to the wired network even while moving from one microcell domain to another. This process is transparent, and the connection to the file server or host is maintained without disruption. The mobile station stays connected to an access point as long as it can. However, once the transfer of data packets needs to be retried or beacons are missed, the station automatically searches for and associates to another access point. This process is referred to as seamless roaming. Figure 1-3 Wireless Infrastructure with Workstations Accessing a Wired LAN Access Point

For Infrastructure Devices Because of differences in component configuration, placement, and physical environment, every network application is a unique installation. Therefore, before you install any wireless infrastructure devices (such as access points, bridges, and base stations, which connect your client adapters to a wired LAN), a site survey must be performed to determine the optimum placement of these devices to maximize range, coverage, and network performance. Appendix F, which is provided for people who are responsible for conducting a site survey, explains how ACUs site survey tool can be used to determine the best placement for infrastructure devices within a wireless network. Note As a rule, infrastructure devices are installed and initially configured prior to client devices. For Client Devices Because the client adapter is a radio device, it is susceptible to RF obstructions and common sources of interference that can reduce throughput and range. Follow these guidelines to ensure the best possible performance:
Install the client adapter in an area where large steel structures such as shelving units, bookcases, and filing cabinets will not obstruct radio signals to and from the client adapter. Install the client adapter away from microwave ovens. Microwave ovens operate on the same frequency as the client adapter and can cause signal interference.

These profiles enable you to use your client adapter in different locations, each of which requires different configuration settings. For example, you may want to set up profiles for using your client adapter at the office, at home, and in public areas such as airports. Once the profiles are created, you can easily switch between them without having to reconfigure your client adapter each time you enter a new location. Profiles are stored in the part of the registry reserved for the client adapter driver and, therefore, are tied to radio type. Consequently, if you set up profiles for a 340 series PC card and later upgrade to a 350 series PC card, all of the profiles will be lost. Similarly, all profiles are lost if you uninstall the client adapters driver. To prevent your profiles from being lost, Cisco recommends that you back up your profiles using the profile managers import/export capability. See the Importing and Exporting Profiles section on page 4-6 for details. Opening Profile Manager To open ACUs profile manager, double-click the Aironet Client Utility (ACU) icon on your desktop to open ACU; then click the Profile Manager icon or select Profile Manager from the Commands drop-down menu. The Profile Manager screen displays (see Figure 4-1).

The Properties screens appear with the name of your new profile in parentheses. Perform one of the following:
If you want this profile to use the default values, click OK. The profile is added to the list of profiles on the Profile Manager screen. If you want to change any of the configuration parameter settings, follow the instructions in Chapter 5. The profile is added to the list of profiles on the Profile Manager screen. Step 5 If you want this profile to be included in auto profile selection, select the Include Profile in Auto Profile Selection checkbox on the Profile Manager screen. Note If your profile is configured to use LEAP, it can be included in auto profile selection only if it has a saved LEAP username and password. For more information on auto profile selection, see the Selecting the Active Profile section on page 4-4. Step 6 Click OK or Apply to save your profile. OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 4-3 Selecting the Active Profile B E TA D R A F T - C I S C O C O N F I D E N T I A L Chapter 4 Using the Profile Manager Selecting the Active Profile Follow the steps below to specify the profile that the client adapter is to use. Note If this is the first time that you are using profile manager and no profiles have been set previously, the Use Selected Profile drop-down box is disabled but displays Driver Advanced Tab Settings, which indicates that the driver is using any settings that were set through the Control Panel. Step 1 Open ACU; then click the Select Profile icon or select Select Profile from the Commands drop-down menu. The Select Profile screen displays (see Figure 4-2). Figure 4-2 Select Profile Screen Step 2 Select one of the following options:
Use Selected Profile This option allows you to select one profile for the client adapter to use. If you choose this option, you also must select the desired profile from the drop-down box. If the client adapter cannot associate to an access point or loses association while using the selected profile, the adapter does not attempt to associate using another profile. To associate, you must select a different profile or select Use Auto Profile Selection.
Use Auto Profile Selection This option causes the client adapters driver to automatically select a profile from the list of profiles that were set up to be included in auto profile selection. The name of the profile that is being used appears in the box to the right of the Use Auto Profile Selection option. If the client adapter loses association for more than 10 seconds (or for more than the time specified by the LEAP authentication timeout value on the LEAP Settings screen if LEAP is enabled), the driver switches automatically to another profile that is included in auto profile selection. The adapter will not switch profiles as long as it remains associated or reassociates within 10 seconds (or within the time specified by the LEAP authentication timeout value). To force the client adapter to associate to a different access point, you must disable auto profile selection and select a new profile. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 4-4 OL-1394-03 Chapter 4 Using the Profile Manager B E TA D R A F T - C I S C O C O N F I D E N T I A L Modifying a Profile Note This option is available only if two or more profiles are included in auto profile selection and if the client adapter is using PCM/LMC/PCI card driver version 8.01 or greater (or mini PCI/PC-Cardbus card driver version 2.20 or greater).

Options: CAM, Max PSP, or Fast PSP Default: CAM (Constantly Awake Mode) Power Save Mode CAM (Constantly Awake Mode) Description Keeps the client adapter powered up continuously so there is little lag in message response time. Max PSP (Max Power Savings) Fast PSP (Power Save Mode) Consumes the most power but offers the highest throughput. Is recommended for desktop computers and devices that use AC power. Causes the access point to buffer incoming messages for the client adapter, which wakes up periodically and polls the access point to see if any buffered messages are waiting for it. The adapter can request each message and then go back to sleep. Conserves the most power but offers the lowest throughput. Is recommended for devices for which power consumption is the ultimate concern (such as small battery-powered devices). Note When you set Max PSP mode and close ACU, the following message appears the next time you open ACU: Maximum Power Save mode will be temporarily disabled while you are running this application. While ACU is open, Fast PSP mode is active. When you close ACU, the card returns to Max PSP mode. Switches between PSP mode and CAM mode, depending on network traffic. This mode switches to CAM when retrieving a large number of packets and switches back to PSP after the packets have been retrieved. Is recommended when power consumption is a concern but you need greater throughput than that allowed by Max PSP.

However, the adapter can use short radio headers only if the access point is also configured to support them and is using them. If any clients associated to an access point are using long headers, then all clients in that cell must also use long headers, even if both this client and the access point have short radio headers enabled. Short radio headers improve throughput performance; long radio headers ensure compatibility with clients and access points that do not support short radio headers. Default: Selected Note This parameter is available only for 2.4-GHz client adapters. Note This parameter is referred to as Preambles on the access point screens. Selecting this checkbox enables the client adapter to adopt the maximum transmit power level and the frequency range of the access point to which it is associated, provided the access point is also configured for world mode. This parameter is available only in infrastructure mode and is designed for users who travel between countries and want their client adapters to associate to access points in different regulatory domains. Default: Deselected Note This parameter is available only for 2.4-GHz client adapters. Note When World Mode is enabled, the client adapter is limited to the maximum transmit power level allowed by the country of operations regulatory agency. Selecting this checkbox causes the client to look for a better access point if its signal strength becomes low and to switch associations if it finds one. Default: Selected Note This parameter is available only if your client adapter is using PCM/LMC/PCI card firmware version 4.25.30 or greater, mini PCI card firmware version 5.00.03 or greater, or PC-Cardbus card firmware version 4.99 or greater.

To access this screen, select the Network Security tab from the Properties screens. Figure 5-5 Network Security Screen Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 5-20 OL-1394-03 Chapter 5 Configuring the Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Setting Network Security Parameters This screen is different from the other Properties screens in that it presents several security features, each of which involves a number of steps. In addition, the security features themselves are complex and need to be understood before they are implemented. Therefore, this section provides an overview of the security features as well as procedures for using them. However, before you determine the appropriate security settings for your client adapter, you must decide how to set the Allow Association To Mixed Cells parameter, which appears at the bottom of the Network Security screen and is not associated to any of the security features. See the Setting the Allow Association To Mixed Cells Parameter section below. Setting the Allow Association To Mixed Cells Parameter The Allow Association To Mixed Cells parameter indicates whether the client adapter can associate to an access point that allows both WEP and non-WEP associations. Follow the steps below to set this parameter. Step 1 Perform one of the following:
Select the Allow Association To Mixed Cells checkbox if the access point with which the client adapter is to associate has WEP set to Optional (regardless of whether WEP is enabled on the adapter). Otherwise, the client adapter is unable to establish a connection with the access point.
Deselect the Allow Association To Mixed Cells checkbox if the access point with which the client adapter is to associate does not have WEP set to Optional. This is the default setting. Note For security reasons, Cisco recommends that WEP-enabled and WEP-disabled clients not be allowed in the same cell because broadcast packets will be sent unencrypted, even to clients running WEP. Step 2 Perform one of the following:

Overview of Security Features 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. OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 5-21 Setting Network Security Parameters B E TA D R A F T - C I S C O C O N F I D E N T I A L Chapter 5 Configuring the Client Adapter 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. Note Refer to the Additional WEP Key Security Features section on page 5-24 for information on three security features that can make your WEP keys even more secure. Static WEP Keys Each device (or profile) 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 adapters registry parameters, it also finds the static WEP keys, unencrypts them, and stores them in volatile memory on the adapter. The Network Security screen enables you to view the current WEP key settings for the client adapter and then to assign new WEP keys or overwrite existing WEP keys as well as to enable or disable static WEP. Refer to the Using Static WEP section on page 5-26 for instructions. 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. Two 802.1X authentication types can be selected in ACU for use with Windows operating systems:
EAP-Cisco Wireless (or LEAP) This authentication type is available for Windows 95, 98, NT, 2000, Me, and XP, as well as non-Windows systems. Support for LEAP is provided not in the Windows operating system but in your client adapters firmware and the Cisco software that supports it. RADIUS servers that support LEAP include Cisco Secure ACS version 2.6 and greater, Cisco Access Registrar version 1.7 and greater, and Funk Softwares Steel-Belted RADIUS version 3.0 and greater. LEAP is enabled or disabled for a specific profile through ACU, provided LEAP was selected during ACU installation. Once enabled, a variety of configuration options are available, including how and when a username and password are entered to begin the authentication process. The username and password are used by the client adapter to perform mutual authentication with the RADIUS server through the access point. The username and password are stored in the client adapters volatile memory; therefore, they are temporary and need to be re-entered whenever power is removed from the adapter, typically due to the client adapter being ejected or the system powering down.

If you want to be able to enable and disable LEAP, you must run the installation program again and select Modify and LEAP.
Host Based EAP Selecting this option enables you to use any 802.1X authentication type for which your operating system has built-in support. For example, Windows XP has built-in support for both EAP-TLS and EAP-MD5. EAP-TLS EAP-TLS is enabled or disabled 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. Once enabled, a few configuration parameters must be set within the operating system. 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 Microsofts documentation for information on downloading and installing the certificate. EAP-MD5 EAP-MD5 is enabled or disabled 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. RADIUS servers that support EAP-MD5 include Cisco Secure ACS version 3.0 and greater and Cisco Access Registrar version 1.8 and greater. Note If you want to authenticate without encrypting the data that is transmitted over your network, you can use EAP-MD5 without static WEP. Note Although EAP-TLS and EAP-MD5 are enabled in the operating system, you can set up profiles in ACU to use these authentication types. To do so, follow the instructions in the Enabling Host-Based EAP section on page 5-31. When you enable Network-EAP on your access point and configure your client adapter for LEAP, EAP-TLS, or EAP-MD5 using ACU or 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 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 (or certificate for EAP-TLS) being the shared secret for authentication. The password (or certificate) is never transmitted during the process.

For LEAP or 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. Refer to the Enabling LEAP section on page 5-28 for instructions on enabling LEAP or to the Enabling Host-Based EAP section on page 5-31 for instructions on enabling EAP-TLS or EAP-MD5.

http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/secur_c/scprt2/scrad.htm Additional WEP Key Security Features The three security features discussed in this section (MIC, TKIP, and broadcast key rotation) are designed to prevent sophisticated attacks on your wireless networks WEP keys. These features are supported in the following client adapter software releases:
PCM/LMC/PCI card firmware version 4.25.23 or greater and PCM/LMC/PCI card driver version 8.01 or greater
Mini PCI card firmware version 5.0 or greater and mini PCI card driver version 2.20 or greater
PC-Cardbus card firmware version 4.99 or greater and PC-Cardbus driver 3.4.9 or greater These features do not need to be enabled on the client adapter; they are supported automatically in the firmware and driver versions listed above. However, they must be enabled on the access point. Note Access point firmware version 11.10T or greater is required to enable these security features. Refer to the Cisco Aironet Access Point Software Configuration Guide for instructions on enabling these security features on the access point. Message Integrity Check (MIC) 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 MIC adds a few bytes to each packet to make the packets tamper-proof. The Status screen indicates if MIC is being used, and the Statistics screen provides MIC statistics. Note If you enable MIC on the access point, your client adapters driver must support these features;
otherwise, the client cannot associate. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 5-24 OL-1394-03 Chapter 5 Configuring the Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Setting Network Security Parameters Temporal Key Integrity Protocol (TKIP) This feature, also referred to as WEP key hashing, 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. It protects both unicast and broadcast WEP keys. Note If you enable TKIP on the access point, your client adapters firmware must support these features;
otherwise, the client cannot associate. Broadcast Key Rotation EAP authentication provides dynamic unicast WEP keys for client devices but uses static broadcast, or multicast, keys. When you enable broadcast WEP key rotation, the access point provides a dynamic broadcast WEP key and changes it at the interval you select. When you enable this feature, only wireless client devices using LEAP or EAP-TLS authentication can associate to the access point. Client devices using static WEP (with open, shared key, or EAP-MD5 authentication) cannot associate. Synchronizing Security Features In order to use any of the security features discussed in this section, both your client adapter and the access point to which it will associate must be set appropriately. Table 5-6 indicates the client and access point settings required for each security feature. This chapter provides specific instructions for enabling the security features on your client adapter. Refer to the Cisco Aironet Access Point Software Configuration Guide for instructions on enabling the features on the access point.

Entering a New Static WEP Key Follow the steps below to enter a new static WEP key for this profile. Step 1 Step 2 Step 3 Select None from the Network Security Type drop-down box on the Network Security screen. Select Use Static WEP Keys under WEP. Select one of the following WEP key entry methods:
Hexadecimal (0-9, A-F) Specifies that the WEP key will be entered in hexadecimal characters, which include 0-9, A-F, and a-f.
ASCII Text Specifies that the WEP key will be entered in ASCII text, which includes alpha characters, numbers, and punctuation marks. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 5-26 OL-1394-03 Chapter 5 Configuring the Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Setting Network Security Parameters Step 4 Select one of the following access point authentication options, which defines how your client adapter will attempt to authenticate to an access point:
Open Authentication Allows your client adapter, regardless of its WEP settings, to authenticate and attempt to communicate with an access point. Open Authentication is the default setting.
Shared Key Authentication Allows your client adapter to communicate only with access points that have the same WEP key. This option is available only if Use Static WEP Keys is selected. In shared key authentication, the access point sends a known unencrypted challenge packet to the client adapter, which encrypts the packet and sends it back to the access point. The access point attempts to decrypt the encrypted packet and sends an authentication response packet indicating the success or failure of the decryption back to the client adapter. If the packet is successfully encrypted/decrypted, the user is considered to be authenticated. Note Cisco recommends that shared key authentication not be used because it presents a security risk. Step 5 For the static WEP key that you are entering (1, 2, 3, or 4), select a WEP key size of 40 or 128 on the right side of the screen. 128-bit client adapters can use 40- or 128-bit keys, but 40-bit adapters can use only 40-bit keys. If 128 bit is not supported by the client adapter, this option is grayed out, and you are unable to select it. Step 6 Obtain the static WEP key from your system administrator and enter it in the blank field for the key you are creating. Follow the guidelines below to enter a new static WEP key:
WEP keys must contain the following number of characters:
10 hexadecimal characters or 5 ASCII text characters for 40-bit keys Example: 5A5A313859 (hexadecimal) or ZZ18Y (ASCII) 26 hexadecimal characters or 13 ASCII text characters for 128-bit keys Example: 5A583135333554595549333534 (hexadecimal) or ZX1535TYUI354 (ASCII)
Your client adapters WEP key must match the WEP key used by the access point (in infrastructure mode) or clients (in ad hoc mode) with which you are planning to communicate.
When setting more than one WEP key, the keys must be assigned to the same WEP key numbers for all devices. For example, WEP key 2 must be WEP key number 2 on all devices. When multiple WEP keys are set, they must be in the same order on all devices. Note After you enter a WEP key, you can write over it, but you cannot edit or delete it. Step 7 Step 8 Click the Transmit Key button to the left of the key you want to use to transmit packets. Only one WEP key can be selected as the transmit key. Click OK to return to the Profile Manager screen; then click OK or Apply to save your changes.

Click OK to return to the Profile Manager screen; then click OK or Apply to save your changes Step 6 Disabling Static WEP If you ever need to disable static WEP for a particular profile, select No WEP under WEP on the Network Security screen, click OK, and click OK or Apply on the Profile Manager screen. Note Selecting LEAP from the Network Security Type drop-down box on the Network Security screen disables static WEP automatically. Enabling LEAP Note Note LEAP authentication is supported only on client adapters that support WEP and use PCM/LMC/PCI card firmware version 4.13 or greater, mini PCI card firmware version 5.0 or greater, or PC-Cardbus firmware version 4.99 or greater. In order to use LEAP authentication, your client adapter and access point firmware must have matching 802.1X draft standards. That is, if the access point uses draft 8 firmware (prior to 11.06) or has draft 8 selected, the client adapter must use draft 8 firmware (prior to 4.25.x). Similarly, if the access point uses draft 10 firmware (11.06 or later) and has draft 10 selected, the client adapter must use draft 10 firmware
(4.25.x or later). Mini PCI firmware and PC-Cardbus card firmware were first released at draft 10.

Use Temporary User Name and Password Requires you to enter the LEAP username and password each time the computer reboots in order to authenticate and gain access to the network.
Use Saved User Name and Password Does not require you to enter a LEAP username and password each time the computer reboots. Authentication occurs automatically as needed using a saved username and password (which are registered with the RADIUS server). Note The Use Saved User Name and Password option is available only if the Allow Saved LEAP User Name and Password checkbox was selected during installation. Note If a profile is using LEAP, it can be included in auto profile selection only if it has a saved user name and password. The Include Profile In Auto Profile Selection checkbox on the Profile Manager screen is grayed out and cannot be selected for profiles that are using LEAP without a saved user name and password. Step 4 Perform one of the following:
If you selected Use Temporary User Name and Password in Step 3, select one of the following options:
Use Windows User Name and Password Causes your Windows username and password to also serve as your LEAP username and password, giving you only one set of credentials to remember. After you log in, the LEAP authentication process begins automatically. This option is the default setting. Automatically Prompt for LEAP User Name and Password Requires you to enter a separate LEAP username and password (which are registered with the RADIUS server) in addition to your regular Windows login in order to start the LEAP authentication process. Manually Prompt for LEAP User Name and Password Requires you to manually invoke the LEAP authentication process as needed using the Manual LEAP Login option from the Commands drop-down menu. You are not prompted to enter a LEAP username and password during the Windows login. This option might be used to support a SoftToken one-time password system or other systems that require additional software that is not available at login.
If you selected Use Saved User Name and Password in Step 3, follow the steps below:
a. Enter a username and password in the appropriate fields. Note Usernames and passwords are limited to 32 ASCII characters each. However, if a domain name is entered in the Domain field, the sum of the username and domain name is limited to 31 ASCII characters. b. Re-enter the password in the Confirm Password field. c. If you wish to specify a domain name that will be passed to the RADIUS server along with your username, enter it in the Domain field.

The chapter contains five sections based on the profiles authentication type and its username and password settings: LEAP (with the Windows username and password, with an automatically prompted login, with a manually prompted login, or with a saved username and password) or host-based EAP. When LEAP authentication begins, the LEAP Authentication in progress message appears. This message provides information about the status of authentication. Table 6-1 lists and explains the stages of LEAP authentication. Table 6-1 Stages of LEAP Authentication Status Message Starting LEAP Authentication Checking Link Status Renewing IP Address Finding Domain Controller Explanation The client adapter associates to an access point, and the LEAP authentication process begins. The client adapter is LEAP authenticated, and the network connection is verified. If DHCP is enabled, the IP address is released and renewed. If you are logging into a domain and the active profile specifies that the domain name be included, an attempt is made to find the domain controller to make sure subsequent access to the domain is successful. Follow the instructions for your profiles authentication type and credential settings to successfully authenticate. Using LEAP with the Windows Username and Password After Profile Selection/Card Insertion After you (or auto profile selection) select a profile that uses LEAP authentication and specifies that your Windows username and password also serve as your LEAP username and password or you eject and reinsert the client adapter while this profile is selected, the following events occur:
1. The LEAP Authentication in progress message appears. 2. If your client adapter authenticates, the message disappears, and the Server Based Authentication field on the ACU Status screen shows LEAP Authenticated. If the authentication attempt fails, an error message appears after the LEAP timeout period has expired. Refer to the Error Messages section in Chapter 9 for the necessary action to take. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 6-2 OL-1394-03 Chapter 6 Using EAP Authentication B E TA D R A F T - C I S C O C O N F I D E N T I A L Using LEAP with the Windows Username and Password After a Reboot/Logoff After your computer reboots or you log off, follow the steps below to LEAP authenticate.

Signal strength The strength of the client adapters radio signal at the time packets are being received. It is displayed as a percentage along the vertical axis.
Signal quality The quality of the client adapters radio signal at the time packets are being received. It is displayed as a percentage along the horizontal axis. The combined result of the signal strength and signal quality is represented by a diagonal line (see Figure 7-5). Where the line falls on the graphical display determines whether the RF link between your client adapter and its associated access point is poor, fair, good, or excellent. The access point that is associated to your client adapter and its MAC address are indicated at the bottom of the display. Note ACUs Status screen also shows signal strength and signal quality. However on the Status screen, these data are represented by histograms. If you want to see a recent history of the RF performance between your client adapter and its associated access point, select the Show History checkbox on the Aironet Client Utility Preferences screen. Black dots on the graphical display show the performance of the last 50 signals. OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 7-17 Running an RF Link Test B E TA D R A F T - C I S C O C O N F I D E N T I A L Chapter 7 Performing Diagnostics Running an RF Link Test ACUs link test tool sends out pings to assess the performance of the RF link. The test is designed to be performed multiple times at various locations throughout your area and is run at the data rate set on ACUs RF Network Properties screen (see the Data Rate parameter in Table 5-3). The results of the link test can be used to determine RF network coverage and ultimately the required number and placement of access points in your network. The test also helps you to avoid areas where performance is weak, thereby eliminating the risk of losing the connection between your client adapter and its associated access point. Because the link test operates above the RF level, it does more than test the RF link between two network devices. It also checks the status of wired sections of the network and verifies that TCP/IP and the proper drivers have been loaded. Note A link test can also be run from an access point through a Telnet session. Refer to the Cisco Aironet Access Point Software Configuration Guide for information. The following prerequisites are required before you can run an RF link test:
The TCP/IP protocol must be installed on your system. Note See the Help section of your Windows operating system for information on installing and setting up TCP/IP.
An IP address must be configured for the access point (or other computer in ad hoc mode). Follow the steps below to run an RF link test. Step 1 Open ACU; then click the Link Test icon or select Linktest from the Commands drop-down menu. The Linktest screen appears (see Figure 7-6). Note The name of the current profile appears in parentheses at the top of the screen.

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 computers 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). Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 8-2 OL-1394-03 Chapter 8 Routine Procedures Inserting and Removing a Client Adapter B E TA D R A F T - C I S C O C O N F I D E N T I A L Figure 8-1 Inserting a PC Card or PC-Cardbus Card into a Computing Device Step 4 Go to the Installing the Driver section on page 3-3 to install the driver for your computers operating system. Inserting a PCI Card Step 1 Step 2 Turn off the PC and all its components. 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.

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 Step 8 Step 9 Reinstall the screw on the CPU back panel and replace the computer cover. Attach the 2-dBi antenna to the cards antenna connector until it is finger-tight. Do not overtighten. 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 Step 2 Step 3 Step 4 Step 5 Completely shut down your computer. Disconnect the client adapters antenna. Remove the computer cover. Remove the screw from the top of the CPU back panel above the PCI expansion slot that holds your client adapter. 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.

Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows 8-24 OL-1394-03 Chapter 8 Routine Procedures B E TA D R A F T - C I S C O C O N F I D E N T I A L 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 Step 2 Open ACU. 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 adapters 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 Adapters Radio On or Off Your client adapters 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 adapters 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 adapters 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 adapters radio on or off.
If your client adapters 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 adapters radio is off, opening ACU and selecting Radio On from the Commands drop-down menu (see Figure 8-4) turns the radio on.

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.

The following topics are covered in this appendix:
Overview, page E-2
Configuring the Client Adapter, page E-4
Using Windows XP to Associate to an Access Point, page E-10
Viewing the Current Status of Your Client Adapter, page E-10 OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows E-1 Appendix E Configuring the Client Adapter through Windows XP B E TA D R A F T - C I S C O C O N F I D E N T I A L 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 Microsofts documentation for Windows XP. Overview of Security Features Static WEP Keys 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. 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 adapters 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. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows E-2 OL-1394-03 Appendix E Configuring the Client Adapter through Windows XP Overview B E TA D R A F T - C I S C O C O N F I D E N T I A L 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 Microsofts 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:

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. OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows E-5 Configuring the Client Adapter Appendix E Configuring the Client Adapter through Windows XP B E TA D R A F T - C I S C O C O N F I D E N T I A L 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). Step 12 Step 13 e. Repeat the previous steps if you want to enter another WEP key. Select the The key is provided for me automatically checkbox if you are planning to use EAP-TLS, which uses dynamic WEP keys. 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.

ACUs 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 networks 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. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows F-2 OL-1394-03 Appendix F Performing a Site Survey B E TA D R A F T - C I S C O C O N F I D E N T I A L 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 Step 2 Step 3 Double-click the Aironet Client Utility (ACU) icon on your desktop to open ACU. Click the Preferences icon or select Preferences from the Options drop-down menu. The Aironet Client Utility Preferences screen appears. 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.

A wireless LAN media access method specified by the IEEE 802.11 specification. Cyclic Redundancy Check (CRC) A method of checking for errors in a received packet. D Data Rates dBi DHCP Dipole DSSS The range of data transmission rates supported by a device. Data rates are measured in megabits per second (Mbps). 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. 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. A type of low-gain (2.2-dBi) antenna consisting of two (often internal) elements. 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 Ethernet 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. 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.

Firmware Software that is programmed on a memory chip and kept in a computers semi-permanent memory. Fragmentation Threshold The size at which packets will be fragmented and transmitted a piece at a time instead of all at once. The setting must be within the range of 64 to 2312 bytes. Full Duplex A means of communication whereby each node receives and transmits simultaneously (two-way). See also Half Duplex. G Gateway A device that connects two otherwise incompatible networks together. Gigahertz. One billion cycles per second. A unit of measure for frequency. GHz H Half Duplex A means of communication whereby each node receives and transmits in turn (one-way). See also Full Duplex. Hexadecimal A set of characters consisting of ten numbers and six letters (0-9, A-F, and a-f). I IEEE Institute of Electrical and Electronic Engineers. A professional society serving electrical engineers through its publications, conferences, and standards development activities. The body responsible for the Ethernet 802.3 and wireless LAN 802.11 specifications. Infrastructure The wired Ethernet network. Infrastructure Device A device that connects client adapters to a wired LAN, such as an access point, bridge, or base station. IP Address The Internet Protocol (IP) address of a station. IP Subnet Mask The number used to identify the IP subnetwork, indicating whether the IP address can be recognized on the LAN or if it must be reached through a gateway. Isotropic An antenna that radiates its signal 360 degrees both vertically and horizontally in a perfect sphere. OL-1394-03 Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows GL-3 Glossary L LEAP M MAC Address MIC B E TA D R A F T - C I S C O C O N F I D E N T I A L 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 adapters 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. The Media Access Control (MAC) address is a unique serial number assigned to a networking device by the manufacturer. 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 adapters 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 transmitters carrier signal. Multicast Packets Packets transmitted to multiple stations. Multipath The echoes created as a radio signal bounces off of physical objects. O OFDM Orthogonal frequency division multiplexing. A multicarrier modulation method for broadband wireless communications. Overrun Packets Packets that were discarded because the access point had a temporary overload of packets to handle. P Packet Q QPSK GL-4 A basic message unit for communication across a network. A packet usually includes routing information, data, and sometimes error detection information. Quadruple phase shift keying. A modulation technique used by IEEE 802.11-compliant wireless LANs for transmission at 2 Mbps. Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows OL-1394-03 B E TA D R A F T - C I S C O C O N F I D E N T I A L Glossary R Radio Channel The frequency at which a radio operates. Range A linear measure of the distance that a transmitter can send a signal. Receiver Sensitivity A measurement of the weakest signal a receiver can receive and still correctly translate it into data. RF Roaming RP-TNC Radio frequency. A generic term for radio-based technology. A feature of some access points that allows users to move through a facility while maintaining an unbroken connection to the LAN. A connector type unique to Cisco Aironet radios and antennas. Part 15.203 of the FCC rules covering 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 SSID T TKIP 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. 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. 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. Transmit Power The power level of radio transmission. U Unicast Packets Packets transmitted in point-to-point communication. UNII Unlicensed National Information Infrastructure. An FCC regulatory domain for 5-GHz wireless devices. UNII bands are 100 MHz wide and divided into four channels when using 802.11a OFDM modulation.
