Release Notes for Cisco Aironet 802.11a/b/g Client Adapters (CB21AG and PI21AG) Install Wizard 3.0
OL-8338-01
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.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.
