Important Notes
ConflictbetweenCiscoSecurityAgentVersion5.0andtheInstallWizardforthe CB21AG or PI21AG
If you have Cisco Security Agent (CSA) version 5.0 installed on your computer and you attempt to run
release 3.5 of the Install Wizard (setup.exe) for the Cisco Aironet CB21AG or PI21AG wireless client,
you might encounter one of two conditions that prevents the completion of software installation.
When you run setup.exe, the CSA opens the following dialog box (see Figure 1).

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.exeof the client installation software
to execute its tasks. However, the CSA might block cmd.exe from executing without notice. The
installation then appears to stall, and the computer must be rebooted. This condition is tracked by
CSCsh16031.
Mismatchbetween HPDC5 100PCI BusController andPCI KeyCacheRegister 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-BF
C1-08002bE10318}
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 Network Connections in the Start > Settings menu in Windows XP, or right click
My Network Places in Windows 2000. Find the CB21AGg instance.
Step 3 Right click the Cisco CB21AG instance, and left click Properties.
Step 4 Choose the Install option and then add a new service.
Step 5 Click Have disk. Go to the \windows\system32 directory and choose wsimd.inf.
Step 6 Select Wireless Intermediate Driver and click OK. The wireless IMD is bound to the adapter.
Step 7 Reboot system.

Incompatibility between PACs Created by ACS Version 3.x.xx and
ACS Version4.0.xx
PACsthatare created by ACSversion3.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 3.5, you might encounter a conflict with third-party supplicants (such as the Juniper
Odyssey)that causes the Cisco clientadapter to lose connection. If you encounter such a conflict, disable
third-party supplicants.
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.
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
OL-12267-01
If you want to enable CCKM on the client adapter, you must choose the WPA/WPA2/CCKM security
option, regardless of whether you wantthe adapter to use WPAorWPA2. The configurationoftheaccess
point to which your client adapter associates determines whether CCKM will be used with 802.1x, WPA,
or WPA2.

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. 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 filein 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.

OL-12267-01
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.
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 conflictbetweenADU and WindowsXPwireless network settings. Simply ignore the Windows icon
and use the ASTU icon to check the status of your client adapter’s wireless connection.
