Cisco Cisco Aironet 350 Wireless LAN Client Adapter Release Notes

CSCsm37565—DNS resolution test failure

The DNS resolution portion of diagnostic channel testing is initiated, and a resolvable host name is 
provided. However, the controller shows that the DNS query was dropped.

Workaround: None.

CSCsm37575—Client event log does not contain failed authentication

EAP-FAST authentication fails because the user enters an invalid password. After the access point 
sends an event log request frame to the client, the client does not send an event log that includes 
information about the failed authentication.

Workaround: None.

CSCsm42303—ADU does not prompt to re-enter user credentials

After EAP-FAST re-authentication after a session timeout, EAP-FAST authentication should fail, 
and an error message window should be displayed. The ADU should also prompt the user to re-enter 
user credentials. However, the prompt dialog box does not appear, and the connection continues.

Workaround: Log on to the Windows workstation with the new password.

CSCsu75684—CB21ag clients might fail reauthentication on an intermittent basis. (Problem found 
not to be client related)

Workaround: None.

CSCsw85317—EAP-FAST authentication fails on a client running on Windows 2000 because an 
API parameter that supports authentication is not supported on Windows 2000 (Windows XP only).

Workaround: Install Windows XP.
