Resolved Caveats

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. During that delay, the CB21AG client sends out a probe request to which the second lightweight access point responds. However, the CB21AG client does not send out an association request.

•CSCsg30531—ADU does not recognize EAP-TLS certificate

Although the client is in the Windows domain and has the correct certificate for EAP-TLS, the user sees the following message:

No machine certificates were found on this computer. Please select a different EAP option.

•CSCsh05264—CASSU does not install if the systemdrive\temp folder is not created

The Cisco Aironet Site Survey Utility (CASSU) does not install under Program Files > Cisco Aironet because the systemdrive\temp\ folder was not created with the initial installation from Setup.exe. Lenovo T60 laptops with Windows XP Pro, SP2, experienced this condition. However, Lenovo T60 with Windows 2000, SP4; Acer TM2350 with Windows XP Pro, SP2; and Lenovo R51 with Windows XP Pro, SP2, did not experience this condition.

•CSCsh13357—ADU power save setting does not work

The ADU power-save setting does not take effect. The wireless sniffer trace shows that the client is still sending null data power-save frames when the adapter is configured for CAM.

Workaround: Change the default Windows registry key for sleep mode from 2 to 0.

The following caveats have been resolved in release 3.5:

•CSCsd02837—CB21AG does not send reassociation request when mobile

The CB21AG client does not send a reassociation request with CCKM keys when it moves from one controller to another controller. The client sends a reassociation request with CCKM keys only when it roams back to the controller to which it was first attached.

•CSCsd80390—The “No machine certificates were found on your computer” message is misleading

When using the Cisco AIR-CB21AG-A-K9 802.11/a/b/g client adapters and running ADU 2.6.0.1, if you try to select ADU clients using EAP-TLS authentication, you see a message stating that no machine certificates were found on your computer, even though the application automatically finds the machine certificates. Also, if you select Use machine Information for Domain Logon under EAP-TLS configuration, you get the same error message. This message will not cause any problem and should only be seen once.

•CSCsd86612—Password window pops up before ACS sends out “Access Reject” message

When entering the incorrect password for EAP-FAST and PEAP-GTC authentication, the ADU pops up the Password window before the ACS sends out an "Access Reject" message to the client. As a result, no "Auth-Fail" messages are logged in ACS.

•CSCse05451—Advanced Status window shows wrong messages when ADU is disassociated

The ADU does not clear status data from the Advanced Status window fields when the client is not associated.
