CB21AG and PI21AG client adapter driver release 3.0

Aironet Desktop Utility (ADU) release 3.0

Cisco Aironet Site Survey Utility release 1.3.01

System Requirements

You need the following items in order to install Install Wizard 3.0 and use its software components:

One of the following Cisco Aironet client adapters:

CB21AG PC-Cardbus card

PI21AG PCI card

A computer running the Windows 2000 or XP operating system


Note Cisco recommends a 300-MHz (or greater) processor.


Service Pack 2 for Windows XP (Professional, Home); Service Pack 4 for Windows 2000.

20 MB of free hard disk space (minimum)

128 MB of RAM or greater (recommended)

If your wireless network uses EAP-TLS or PEAP authentication, Certificate Authority (CA) and user certificates for EAP-TLS authentication or CA certificate for PEAP authentication

If your wireless network uses PEAP (EAP-GTC) authentication with a One-Time Password (OTP) user database:

A hardware token device from OTP vendors or the Secure Computing SofToken program (version 2.1 or later)

Your hardware or software token password

The Microsoft 802.1X supplicant, if your client adapter is installed on a Windows 2000 device and uses PEAP (EAP-MSCHAPV2) with machine authentication

All necessary infrastructure devices (such as access points, servers, gateways, user databases, etc.) must be properly configured for any authentication type you plan to enable on the client.

The following information from your system administrator:

The logical name for your workstation (also referred to as client name)

The protocols necessary to bind to the client adapter, such as TCP/IP

The case-sensitive service set identifier (SSID) for your RF network

If your network setup does not include a DHCP server, the IP address, subnet mask, and default gateway address of your computer

The wired equivalent privacy (WEP) keys of the access points with which your client adapter will communicate, if your wireless network uses static WEP for security

The username and password for your network account

Protected access credentials (PAC) file if your wireless network uses EAP-FAST authentication with manual PAC provisioning

Important Notes

Mismatch between HP DC5 100 PCI Bus Controller and PCI Key Cache Register on PI21AG Chip

A mismatch exists between the HP DC5100 PCI bus controller and the PCI key cache register on the chip of the PI21AG. The key cache uses a 48-bit register in which the PI21AG sends out two writes on the PCI bus back to back (DWORD and WORD). The controller on the device cannot handle two consecutive write cycles on the bus, which causes a fatal error on the PCI bus.

You should slow down the write operations to the key cache by performing a register read before and after a register write. To slow down the write operations, install registry key "singleWriteKC=1." The path of the "singleWriteKC=1" registry key is the following:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}

You should not see any system degradation or performance hits, as the key cache is only changed every few minutes. An additional read before the second write cycle only lasts a few micro seconds in the PCI space.

Installing the CB21AG Intermediate Driver Manually

In some instances, the installation of the CB21AG software might not work as expected because the intermediate driver might not have installed correctly. In this situation, the installer might not detect this condition, and the rest of the software will not function correctly.

The CB21AG intermediate driver must be installed manually. To install the intermediate driver manually, follow these steps:


Step 1 Insert the client adapter.

Step 2 Click on "Network Connections" in the Start > Settings menu in Windows XP, or right click on "My Network Places" in Windows 2000. Find the CB21AGg instance.

Step 3 Right click on the Cisco CB21AG instance, and left click on Properties.

Step 4 Choose the "Install" option and then add a new service.

Step 5 Choose the "Have disk" button. Go to \windows\system32 directory and choose wsimd.inf.

Step 6 Highlight and select "Wireless Intermediate Driver" and click "ok" button. The wireless IMD is bound to the adapter.

Step 7 Reboot system.


Incompatibility between PACs Created by ACS Version 3.x.xx and ACS Version 4.0.xx

PACs that are created by ACS version 3.x.xx are not compatible with ACS version 4.0.xx. Client stations must import new PACs. If you select auto-provisioning, new PACs will automatically be generated and used. However, if you select manual provisioning, you must manually export new PACs to the client stations.

If a user wants to authenticate to ACS version 4.0.xx and version 3.x.xx at different times, both PACs must remain on the client station. The ADU is capable of automatically selecting the appropriate PAC.

However, if you experiences authentication failures after upgrading the software, delete all the PACs provisioned from the 3.x.xx server.

Conflict with Third-Party Supplicants

When using release 3.0, you might encounter a conflict with third-party supplicants (such as the Meetinghouse Aegis or the Juniper Odyssey) that causes the Cisco client adapter to lose connection. If you encounter such a conflict, disable third-party supplicants.

Customized Installation Images (Notice to IT Professionals)


Caution Use caution when bundling the client adapter software into a customized installation image. If the registry settings are modified, the software may not install and uninstall properly.

Client Adapter Software Compatibility


Caution Cisco Aironet CB21AG and PI21AG client adapter software is incompatible with other Cisco Aironet client adapter software. The Aironet Desktop Utility (ADU) must be used with CB21AG and PI21AG cards, and the Aironet Client Utility (ACU) must be used with all other Cisco Aironet client adapters.

Installing the Novell Client

If you are going to use the Novell Client, be sure to install it on your computer prior to installing the client adapter software.

Enabling CCKM Fast Secure Roaming

If you want to enable CCKM on the client adapter, you must choose the WPA/WPA2/CCKM security option, regardless of whether you want the adapter to use WPA or WPA2. The configuration of the access point to which your client adapter associates determines whether CCKM will be used with 802.1x, WPA, or WPA2.

Access Point Setting for LEAP or EAP-FAST Authentication

Access points must be set for both Network-EAP and open authentication in order to associate to CB21AG and PI21AG client adapters running LEAP with WPA/WPA2/CCKM or EAP-FAST.

EAP-FAST Fails When Access Point Configured as Local RADIUS Server

The client adapter fails to authenticate using EAP-FAST when the access point is running Cisco IOS Release 12.3(2)JA2 and is configured as a local RADIUS server. The following message appears: "Unable to EAP-FAST authenticate the wireless user in the specified amount of time. Network infrastructure might be down."

GINA Error on Bootup

If your computer ever experiences a GINA error on bootup, boot to the safe mode command prompt. Then copy the msgina.dll file in the WinNT\System32 directory (Windows 2000) or Windows\System32 directory (Windows XP) over to a file named cscogina.dll. The copy command enables you to copy a source file (msgina.dll) to a destination file (cscogina.dll) within the same directory.

Reboot Required When Uninstalling ACU and ADU


Caution When you uninstall ACU and ADU, be sure to reboot your computer when prompted. Otherwise, the system may be rendered unable to boot, displaying the message "The Logon User Interface DLL cswGina.dll failed to load. Contact your system administrator to replace the DLL or restore the original DLL."

Uninstalling Software Components

All profiles and stored PAC files are deleted if you use the Uninstall the previous installation option on the Previous Installation Detected Install Wizard window to uninstall the client adapter software. Cisco recommends that you use the Profile Manager's export feature to save your profiles before uninstalling the software.

Profiles for PC-Cardbus Cards

The profiles for PC-Cardbus cards are tied to the slot in which the card is inserted. Therefore, you must always insert your PC-Cardbus card into the same slot, create profiles for both slots, or export the profiles for one slot and import them for the other slot.

Auto Profile Selection Enables Scan of Wireless Modes in Auto-Selected Profiles

When you enable auto profile selection, the client adapter ignores the selected profile's wireless mode setting and scans the wireless modes specified by all the profiles in the auto profile selection list for an available network. Using this method, the client does not need to disassociate nor change the current profile while looking for networks in other profiles.

ASTU Exit Option

The Exit option on the Aironet System Tray Utility (ASTU) pop-up menu closes both ASTU and ADU.

Windows Wireless Network Connection Icon Shows Unavailable Connection (Windows XP Only)

If your computer is running Windows XP and you configured your client adapter using ADU, the Windows Wireless Network Connection icon in the Windows system tray may be marked with a red X and show an unavailable connection even though a wireless connection exists. This condition is caused by a conflict between ADU and Windows XP's wireless network settings. Simply ignore the Windows icon and use the ASTU icon to check the status of your client adapter's wireless connection.

Supporting Documentation

The Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration Guide (OL-4211-05) pertains specifically to CB21AG and PI21AG client adapters. If you are using a Cisco Aironet 340, 350, or CB20A client adapter, refer to the Installation and Configuration Guide for that client adapter and your computer's operating system.

New and Changed Information

EAP-FAST Enhancements

The following is a list of EAP-FAST enhancements, which are accessible through the ADU user interface:

Support of additional EAP authentication methods

Version 3.0 of ADU supports three EAP methods in both the PAC auto provisioning phase and the EAP-FAST authentication phase. These methods are:

EAP-MSCHAPv2

EAP-GTC

EAP-TLS

PAC configuration and management screens

Finding the Version of ADU and Other Software Components

To find the version of ADU and other software components installed for your client adapter, open ADU and choose the About Aironet Desktop Utility option from the Help drop-down menu. The About window shows the current version of the following software components: ADU, ACAU, the authentication supplicant, the protocol driver, and the Windows NDIS miniport driver.

Caveats

This section describes the open, resolved, and closed caveats for the software components in this release.

Open Caveats

The following caveats are not resolved in CB21AG and PI21AG client adapter software release 3.0:

CSCsd31365—When the client connects to an access point that does not broadcast its SSID, the Cisco Aironet Site Survey Utility AP Scan List may not the access point's SSID for a short time.

CSCsd80390—The "No machine certificates were found on your computer" message is misleading

When using the Cisco AIR-CB21AG-A-K9 802.11/a/b/g client adapters and running ADU 2.6.0.1, if you try to select ADU clients using EAP-TLS authentication, you see a message stating that no machine certificates were found on your computer, even though the application automatically finds the machine certificates. Also, if you select Use machine Information for Domain Logon under EAP-TLS configuration, you get the same error message. This message will not cause any problem and should only be seen once.

CSCsd86612—If a user enters an incorrect password, the ADU will prompt the user to re-enter the password, but the ACS server will not record an invalid login attempt in its logs.

This behavior is by design. The ACS server does not log an EAP failure because it gives the user a chance to reauthenticate.

CSCse05471—The CB21 client adapter cannot pass the authentication phase with a Traditional Chinese username

This only occurs on a machine with the Traditional Chinese language pack and a 2-byte username. When configuring the EAP-FAST authentication with Machine PAC, the STAUT failed to roam between access points.

CSCse25438—The Advanced Status window of the ADU application shows the wrong SSID information

In the ADU application, if you click Current Status and Advanced, you will notice that the Network Name (SSID) field displays only the first two characters of the SSID in the Advanced Status window. This happens when the SSID is a long string of characters with white spaces in between. The window wraps the string around into multiple lines and shows only one line.

CSCse37717—EAP-FAST roaming fails with machine PAC

Workaround: Uncheck the session resume check box in the ACS 4.0 RADIUS server.

CSCse44432—PI21AG card in HP DC5100 might result in NMI parity error

With a PI21AG card, long software installations over the network might fail. If error reporting is enabled in the BIOS, this failure might appear as a BIOS-level blue screen error. If error reporting is not enabled, this failure appears as a loss of network connectivity even though the card appears to be associated.

This condition occurs when the PI21AG card is used in a HP DC5100 and is associtated to an AP1200 with an 802.11b radio. This condition does not occur with an AP with an 802.11g radio.

CSCse49324—CB21AG retransmission mechanism has problems with RRM in LWAPP network

A CB21AG client that is operating in an LWAPP infrastructure loses connection for small periods of time. When the AP is performing radio resource management (RRM), the AP goes off channel. During these periods, the AP cannot hear and answer ACK and RTS frames from the client. The client card initiates a scan for another AP, and network traffic for the client is affected.

Workaround: Increase the HwTxRetries value from 4 to 14 (registry entry) so that the client card continues to retry for the 20 to 30 milliseconds that the AP is off channel.

Resolved Caveats

The following caveat has been resolved in release 3.0:

CSCeh59294—Failure to find domain controller during LEAP authentication

The client adapter may be unable to find a domain controller when attempting to LEAP authenticate. This state can be a normal condition due to network unavailability.

CSCeh59374—Switching between profiles is slow

The client adapter may take up to 40 seconds to switch from one profile to another.

CSCei30892—Multi-byte username cannot pass EAP-FAST authentication

The CB21AG and PI21AG client adapters are unable to successfully EAP-FAST authenticate with an ACS server when the username contains multi-byte characters.

CSCei40773—Incorrect messages on LEAP and EAP-FAST Authentication Status windows

The LEAP and EAP-FAST Authentication Status windows show a successful status even if an IPX frame type is not detected or a domain controller is not found on the network.

CSCsb46833—IOS access point with EAP-secured SSID toggles between "Open" and "Secure"

When an IOS access point is configured with an SSID mapped to a VLAN and the SSID is secured with EAP and WPA-TKIP, then in the site survey utility's AP scan list, the access point may toggle between "Open" and "Secure." In this mode, the access point sends out the network configuration information in the beacon and probe responses. Certain fields may differ between beacons and probe responses when VLANs are enabled. The client adapter driver may report the fields from the beacon frame or probe response frame, whichever is received last.

CSCsb53874—Timing error prevents MAC address authentication

When using MAC address authentication, the client adapter fails to authenticate due to a timing error. To work around this problem, do not use MAC address authentication.

CSCsb80735—LEAP-authenticated CB21AG loses connectivity

A LEAP-authenticated CB21AG using WEP mandatory encryption might lose connectivity after some time and be unable to find an AP. This condition has been observed for an IBM T42 laptop running Windows XP, service pack 1 or 2.

CSCsc25020—PEAP-GTC/AES authentication passes with any certificate chosen

PEAP-GTC/AES authentications passes when "any" is chosen under the trusted root certificate authorities. PEAP-GTC/AES authentications also passes with any vendor certificate chosen under the trusted root certificate authorities.

CSCsc46853—ADU has to be installed twice

After the first installation and reboot, all areas are grayed out after clicking on the ADU icon in Profile Management. The user cannot create or modify the profile. After reinstallation and reboot, the user can configure the SSID and associate to an access point.

CSCsc51460—CB21AG does not associate with an CCKM+AES AP

A CB21AG client configured for WPA, WPA2, CCKM, or EAP is unable to associate on an SSID that is configured for AES+CCKM.

CSCsc62060—ADU bundled with Site Survey Utility does not reflect changes to RF correctly

The Site Survey Utility bundled with the CB21AG card is slow to recognize changes to the RF environment.

CSCsc78069—Link status showing that the user is authenticating even though the user is already authenticated

The link status on the ADU is showing "authenticating...." even though the client is already authenticated and is able to pass traffic.

CSCsc84990—ADU versions 2.1 and 2.5 fail while importing PAC files

While importing PAC files, the error message "Unable to save imported PAC data. Access denied." may appear. This problem affects versions 2.1 and 2.5 of ADU.

CSCsd08479—CB21AG/PI21AG client sometimes does MediaDisconnect if it roams

A CB21AG/PI21AG client, when roaming twice in rapid succession, might undergo a link-layer media disconnect event, which will cause upper layer applications to lose connectivity for 30-40 seconds.

CSCsd18192—Client does not display password window on ACS redundancy

The ADU client does display the password window under these circumstances:

upon entering an invalid user name or password.

upon changing the user profile from a valid one to an invalid one.

CSCsd39987—No valid PAC with local RADIUS after few days with EAP-FAST

CB21AG clients authenticate using EAP-FAST and receive a PAC through auto-provisioning from a local RADIUS server (access point), but between one hour and a few days later, clients do not have a valid PAC when booted. 350 Clients do not see this issue.

CSCsd44604—Unable to import the EAP-FAST PAC file of ACS 4.0

The EAP-FAST PAC file that is exported by the CSUtil utility on ACS 4.0 cannot be imported to ADU manually.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
