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 802.11a band and when the user uses the supplicant that is bundled with the ADU.

CSCsg99350—CB21AG client does not follow data-rate setting on WLC

The CB21AG client does not follow the data-rate setting on the WLC. The client uses the 1-Mbps and 2-Mbps data rate for 802.11 data packets even though these rates were disabled on the WLC.

CSCsd80097—CB21AG G channel problem with Compaq hardware

A CB21AG client that is running release 2.6, 3.0, or 3.5 experiences roaming inconsistencies with the G rates that are enabled if the client is installed on a Compaq NX 6110. These roaming inconsistencies are only seen on this model PC. This model laptop does not get the proper cardbus controller driver installed when the user initializes the system software setup.

Workaround: Go to the Hewlett-Packard site and download sp30219. This service pack has the driver installation program for the necessary cardbus controller.

CSCse05471—The CB21 client adapter cannot pass the authentication phase with a Traditional Chinese username

This only occurs on a machine with the Traditional Chinese language pack and a 2-byte username. When configuring the EAP-FAST authentication with Machine PAC, the STAUT failed to roam between access points.

CSCse37717—EAP-FAST roaming fails with machine PAC

Workaround: Uncheck the session resume check box in the ACS 4.0 RADIUS server.

CSCsf96751—CB21AG client does not function properly with PC network bridge feature

Network bridging on a PC with the CB21AG client and a wired NIC initially allows traffic to pass from end to end. However, if the PC is rebooted, the network bridge does not start because the CB21AG does not associate to the AP.

Workaround: Disable the network bridge, reassociate the CB21AG with the AP, and create the network bridge again. Do not reboot the PC.

CSCsg65164—Authentication timeout for EAP-FAST occurs after 60 seconds

The ADU sends an EAPOL-start message after 30 seconds. However, the login window does not appear. The ADU sends a second EAPOL-start message after 30 seconds. After this second message, the login window appears. It takes 60 seconds for the login window to appear, even when the Authentication Timeout Value is set to 30 seconds.

CSCsg78668—Compaq EVO N1020V laptop hangs during installation of CB21AG

A Compaq (HP) EVO N1020V laptop that is running Windows XP might stall while running the CB21AG Install Wizard. This problem might affect other laptops from other vendors.
