Introduction

This document describes system requirements, important notes, installation instructions, and caveats for CB21AG and PI21AG client adapter Install Wizard release 1.0 and the following software included in the Install Wizard file:

CB21AG and PI21AG client adapter driver release 1.0

Aironet Desktop Utility (ADU) release 1.0

System Requirements

You need the following in order to install Install Wizard release 1.0 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 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."

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.

Open Caveats

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

Open Driver Caveats

The following caveats have not been resolved in CB21AG and PI21AG client adapter driver 1.0.

CSCed21099—PEAP does not operate with domain login

PEAP authentication does not operate with domain login. To work around this issue, 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 issue, 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 issue, upgrade the VxWorks access point to firmware version 12.04 or later.

Open ADU Caveats

The following caveats have not been resolved in ADU 1.0.

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 issue, upgrade the VxWorks access point to firmware version 12.04 or later.

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.

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.

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 issue, set up a Windows password that contains at least one character.
