Release Notes for Cisco Aironet 802.11a/b/g Client Adapters (CB21AG and PI21AG) Install Wizard 3.
Introduction 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 3.5 and the following software included in the Install Wizard file: • CB21AG and PI21AG client adapter driver release 3.5 • Aironet Desktop Utility (ADU) release 3.5 • Cisco Aironet Site Survey Utility release 1.4.
Important Notes – 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 Conflict between Cisco Security Agent Version 5.
Important Notes The following are the two conditions: • If you click No, you are instructing the CSA to disallow devcon.exe of the client installation software from executing its tasks. The installation then appears to stall. The installation does not complete, and the computer must be rebooted. To avoid this behavior, disable the CSA before installing the wireless client software. This condition is tracked by CSCsg83510. • If you click Yes, you are instructing the CSA to allow devcon.
Important Notes 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.
Important Notes 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.
New and Changed Information 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. With this method, the client does not need to disassociate or to change the current profile while looking for networks in other profiles.
Installing or Upgrading Client Adapter Software Selecting Software to Manage Client Adapter You can select the software that you would like to use to configure and display information about your wireless device. You can choose from Windows software, the Aironet Desktop Utility, or a third-party tool. For more information about the new updates, refer to the Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration Guide, OL-4211-06.

Caveats Caveats This section describes the open and resolved caveats for the software components in this release. Open Caveats The following caveats are not resolved in CB21AG and PI21AG client adapter software release 3.5: • CSCsg99156—PI21AG does not respond to identity requests if 802.11a is used The wireless client might lose connectivity during roaming. When this condition occurs, the ADU prompts for a username and password. This condition occurs only when the user connects in the 802.
Caveats • CSCsg99322—CB21AG client does not roam smoothly between two lightweight access points A CB21AG client does not roam smoothly between two lightweight access points. If a client associated with a lightweight access point that has an RSSI of –90 dBm but then tries to associate with another lightweight access point that has an RSSI of –45 dBm, the client does not roam to the new AP for between 5 and 10 seconds.
Caveats • 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.
Troubleshooting Step 1 Open the Network Connections window from the Control Panel. Step 2 Right click the CB21AG device icon and choose Properties. Step 3 Click Configure. The Adapter Properties window appears. Step 4 Click the Advanced tab. Step 5 Choose the registry parameters that are listed above. Enter new values. Step 6 Click OK. Note The new registry parameter values might not take effect until you disable and enable the device again or until you reboot the system.
