Introduction

This document describes system requirements, important notes, new and changed information, installation and upgrade procedures, and caveats for CB21AG and PI21AG client adapter Install Wizard release 1.1 and the following software included in the Install Wizard file:

CB21AG and PI21AG client adapter driver release 1.1

Aironet Desktop Utility (ADU) release 1.1

System Requirements

You need the following in order to install Install Wizard 1.1 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 1 for Windows XP

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 (release 2.1 or later)

Your hardware or software token password

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

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.

Important Notes

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.

Workaround for PEAP Domain Login Issue (CSCed21099)

To enable your client adapter to PEAP authenticate in a multiple domain environment, create a profile in ADU that uses PEAP authentication but do not enter a domain name in the Specific Server or Domain field on the Advanced Configuration window. If the Login Name field is not filled in automatically, enter your username with nothing after it (for example, jsmith).

When you activate this profile, Cisco Secure ACS searches for the login name across all domain databases and attempts to authenticate the user against the first database that matches the username. While not specifying a domain name may increase the time it takes for your client adapter to authenticate, it helps to ensure that the authentication attempt is successful.


Note This workaround applies to both Windows 2000 and XP.


Workaround for EAP-TLS Domain Login Issue (CSCee23962)

To enable your client adapter to EAP-TLS authenticate in a multiple domain environment, create a profile in ADU that uses EAP-TLS authentication but do not enter a domain name in the Server/Domain Name field on the Define Certificate window. If the Login Name field is not filled in automatically, enter your username in this format: username@domain (for example, jsmith@acs-test.cisco.com).


Note This workaround applies to both Windows 2000 and XP.


Reboot Required When Uninstalling ACU and ADU


Caution When you uninstall ACU and ADU, make sure you 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."

GINA Error upon Reboot

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.

Other Vendor Software Attempts to Run

If you insert the client adapter into your computer prior to using the Install Wizard to install the client adapter software, other vendor software may attempt to run. To prevent this from occurring, follow one of these steps. For a CB21AG card, run the Install Wizard and insert the card when prompted. For a PI21AG card, run the Install Wizard until it completes; then turn off your computer and insert the card.

Uninstalling Software Components

All profiles 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.

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 (part number OL-4211-01) 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

Radio Management Support

Install Wizard 1.1 includes client adapter radio management support for CiscoWorks Wireless LAN Solution Engine (WLSE) software release 2.7.

Wireless Mode Priority

When you select more than one option for the Wireless Mode parameter on the Profile Management (Advanced) window in ADU, the client adapter attempts to use the wireless modes in this order:
5 GHz 54 Mbps, 2.4 GHz 54 Mbps, 2.4 GHz 11 Mbps.

PEAP Password Change

When you enter your PEAP password in ADU 1.0, the password appears in clear text and therefore is visible on the screen. In ADU 1.1, the PEAP password appears as a series of asterisks so the password cannot be seen.

Connection Status Window

The name of the ASTU Connection Status window has been changed to Cisco Aironet 802.11a/b/g Wireless Adapter Connection Status window.

Caveats

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

Open Caveats

Open Driver Caveats

The following caveats are not resolved in CB21AG and PI21AG client adapter driver 1.1.

CSCee70072—Auto profile selection causes no connectivity until logon

When auto profile selection is enabled, connectivity does not occur until the user logs in. To work around this problem, disable auto profile selection if you want your client adapter to establish connectivity prior to logon.

CSCin75649—Failure to find domain controller during LEAP authentication

The LEAP Authentication Status screen may show an incorrect status for the Finding Domain Controller field, and the client adapter may or may not successfully LEAP authenticate regardless of the status shown for this field.

CSCin74956 and CSCee69323—Client fails to get IP address when CCKM CKIP+CMIC is used with 12.2(15)JA

Clients fail to obtain an IP address when attempting to associate to an access point that is running Cisco IOS Release 12.2(15)JA and is configured for CCKM with CKIP+CMIC. To work around this problem, configure the access point for CCKM with TKIP+Michael MIC rather than CKIP+CMIC.

CSCed21099—PEAP does not operate with domain login

PEAP authentication does not operate with domain login. To work around this problem, create a profile in ADU that uses PEAP authentication but do not enter a domain name in the Specific Server or Domain field on the Advanced Configuration window. If the Login Name field is not filled in automatically, enter your username with nothing after it (for example, jsmith).

When you activate this profile, Cisco Secure ACS searches for the login name across all domain databases and attempts to authenticate the user against the first database that matches the username. While not specifying a domain name may increase the time it takes for your client adapter to authenticate, it helps to ensure that the authentication attempt is successful. This workaround applies to both Windows 2000 and XP.

CSCee23962—EAP-TLS does not operate with domain login

EAP-TLS authentication does not operate with domain login. To work around this problem, create a profile in ADU that uses EAP-TLS authentication but do not enter a domain name in the Server/Domain Name field on the Define Certificate window. If the Login Name field is not filled in automatically, enter your username in this format: username@domain (for example, jsmith@acs-test.cisco.com). This workaround applies to both Windows 2000 and XP.

CSCed40520—Up to 5-minute delay for initial boot

Some computers may experience up to a 5-minute delay during the first boot after installation. Subsequent boots are normal.

CSCec08294—Client remains in access point's association table

The client remains in the access point's association table for approximately 30 minutes after it has been disabled.

CSCed23644—DHCP does not operate if MIC is enabled on VxWorks access points

DHCP does not operate with CB21AG and PI21AG client adapters if MIC is enabled on VxWorks access points. To work around this problem, upgrade the VxWorks access points to firmware version 12.04 or later.

Open ADU Caveats

The following caveats are not resolved in ADU 1.1.

CSCee85197—Cannot create driver diskettes when adapter not inserted

If you try to use the Install Wizard to create driver installation diskettes when a client adapter is not inserted in your computer, the following message appears and the operation terminates: "Cisco Aironet 802.11a/b/g wireless adapter software update can't proceed. Please insert the adapter in the system and try again."

CSCed72076—Channels 13 and 14 not available in ad hoc mode for Japanese cards

The Japan regulatory domain supports channels 1 through 14 for IEEE 802.11b communications and channels 1 through 13 for IEEE 802.11g communications. However, channels 13 and 14 do not appear in the Channels drop-down list on the ADU Profile Management (Advanced) window for client adapters that are configured for use in Japan.

CSCin58718—ADU shows invalid IP address for VxWorks access points

The ADU Advanced Status window shows an Associated AP IP Address of 0.0.0.0 when the client adapter is associated to a VxWorks access point. To work around this problem, upgrade the VxWorks access point to firmware version 12.04 or later.

CSCee14610—PEAP authentication attempts fail for users with zero-length passwords

PEAP authentication attempts fail for users with zero-length passwords. To work around this problem, set up a Windows password that contains at least one character.

CSCec39604—EAP-TLS authentication attempts fail for users with zero-length passwords

EAP-TLS authentication attempts fail for users with zero-length passwords. To work around this problem, set up a Windows password that contains at least one character.

Resolved Caveats

Resolved Driver Caveats

The following caveats are resolved in CB21AG and PI21AG client adapter driver 1.1.

CSCee31228—Client cannot associate while guest mode enabled on VLAN

A client adapter that is using the Windows's XP Wireless Configuration Manager cannot associate when guest mode is enabled on the VLAN.

CSCed77211—Driver conflict may cause blue screen

A driver conflict with the Microsoft Wireless Configuration Manager may cause the DRIVER_IRQL_NOT_LESS_OR_EQUAL error to appear and a blue screen to occur.

CSCee13817 and CSCee27331—Client fails to reach SNA server on initial boot-up

Clients that are using an SNA application may fail to reach the SNA server on initial boot-up. However, the clients can reach the SNA server on subsequent boots.

CSCed80994—Authentication fails when access point is configured for CCKM and 40- or 128-bit WEP

The client adapter fails to authenticate to access points that are configured for CCKM and 40- or 128-bit WEP. If you change the access point's configuration to TKIP or CKIP, the client adapter authenticates successfully.

CSCed84100—Windows may fail to load after ADU installation

After you install ADU and your computer reboots, a winlogon.exe failure may occur and cause your computer to reboot again. In some circumstances, a reboot cycle may occur without the winlogon.exe notification.

CSCed84477—Inability to browse to Novell NDS server with MIC enabled

When MIC is enabled on the access point, the client adapter cannot browse to the Novell NDS server.

CSCed78930 and CSCee01822—Novell login timing issue

A Novell timing issue causes the following errors: "Cannot find tree or server," "Cannot log into network," "No Novell servers could be found," etc. These errors occur because the Novell login is attempted prior to the IP address being received. This issue extends to any network login that requires connectivity before login.

Resolved ADU Caveats

The following caveats are resolved in ADU 1.1.

CSCin63049—Incorrect behavior on failed LEAP authentication

If LEAP authentication fails because the authentication server is down, a message appears indicating that the LEAP authentication timeout has expired. When you click OK, you are prompted to re-enter your user credentials even though the failure was caused by the authentication server and not improper credentials.

This problem is resolved in ADU 1.1. The following message now appears when LEAP authentication times out: "Authentication timed out. Do you want to retry?" Click Retry to try to authenticate again using the same credentials or click Cancel to cancel the operation. You are no longer prompted to re-enter your username and password.

CSCee23977—PEAP password appears in clear text

When you enter your PEAP password in ADU 1.0, the password appears in clear text and therefore is visible on the screen. In ADU 1.1, the PEAP password appears as a series of asterisks so that the password cannot be seen.

CSCed29755—Client adapter serial number is backwards

The serial number shown on the ADU Adapter Information window is backwards. For example, a serial number of 0123456789A displays as A9876543210.

CSCec67910—ADU may incorrectly show 11 Mbps link speed

When the client adapter associates to an access point with a fixed data rate of 6 or 9 Mbps, the ADU Advanced Status window may incorrectly show 11 Mbps for the current link speed.

After you describe your situation, the TAC Service Request Tool automatically provides recommended solutions. If your issue is not resolved using the recommended resources, your service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at this URL:

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553 2447

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)—Your 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 operation 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 your network is impaired, but 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.
