Release Notes for Cisco Aironet 802.11a/b/g Client Adapters (CB21AG and PI21AG) Install Wizard 2.5
OL-8008-01
Caveats
• CSCsb81180—Client adapters may randomly disassociate
Client adapters may randomly disassociate from their access points and then fail to reassociate. To
work around this problem, reboot the client.
• CSCsb90765—Client adapter fails to reassociate after WLSM is reset
When the Wireless LAN Services Module (WLSM) is rebooted, the client adapter disassociates
from its access point. When WLSM comes back online and Wireless Domain Services (WDS) is
available again, the client adapter does not automatically reassociate and therefore fails to reregister
with WDS. To work around this problem, manually reauthenticate the client adapter using ADU.
Resolved Caveats
The following caveats are resolved in CB21AG and PI21AG client adapter software release 2.5.
• CSCed93298—The client adapter’s IP address may display incorrectly
The client adapter’s IP address may appear as 0.0.0.0 when the adapter is associated to a workgroup
bridge that is configured as a root access point. The IP address usually displays correctly after a few
minutes.
• CSCee70072—Auto-profile selection prevents connectivity until login
When auto-profile selection is enabled in ADU, connectivity does not occur until the user logs in.
• CSCef74909—IPX auto frame detection may not work correctly
When using Novell IPX client software, the client adapter may not allow proper detection of the IPX
frame type. As a result, the Novell IPX stack is unable to log into the Novell server. The IPX stack RIP
requester stops trying after 2.5 seconds, which is the default value. To work around this problem,
you can change the timeout value in the registry at the following location:
\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NwlnkIpx\Parameters
The parameter is a REG_DWORD named RipCount. Increase the value to 20 seconds by entering
hex 28 (40 decimal). The units are in half seconds.
• CSCeg81842—Failure to get IP address when Fast PSP is enabled
The client adapter may be unable to get an IP address when Fast PSP (Power Save Mode) is enabled
in ADU. To work around this problem, use CAM (Constantly Awake Mode) instead.
• CSCeh03426—Client experiences throughput values below 1 Mbps
When 6 or 9 Mbps is enabled on the access point, the client adapter experiences throughput values
below 1 Mbps. To work around this problem, set the access point to its default data rate.
• CSCeh59373—ADU unmanageable after first install
If ADU is unusable after you install the client adapter software, uninstall the client adapter software
and then reinstall it.
• CSCeh60492—Failure to load group policies on boot-up
When Host Based EAP and PEAP (EAP-MSCHAP V2) machine authentication are enabled, group
policy objects (GPOs) may not be loaded upon boot-up.
• CSCeh66276—ADU does not prompt for PIN during PEAP (EAP-GTC) reauthentication
During PEAP (EAP-GTC) reauthentication, ADU does not prompt you to enter a PIN. When the
client roams out of the coverage area and then returns or its radio is disabled and then reenabled,
you are not prompted to re-enter your credentials. The client reconnects to the network and starts to
transfer data.
