Release Notes for Cisco Aironet Client Adapter Firmware, Version 5.02.20
OL-3990-01
New and Changed Information
New and Changed Information
This section describes new and changed information for Cisco Aironet client adapter firmware release 
5.02.20.
Reporting Access Points that Fail LEAP Authentication
Client adapter firmware version 5.02.20 and the following access point firmware versions support a new 
feature that is designed to detect access points that fail LEAP authentication:
12.00T or greater (340, 350, and 1200 series access points)
12.2(4)JA or greater (1100 series access points)
An access point running one of these firmware versions records a message in the system log when a 
client running firmware version 5.02.20 discovers and reports another access point in the wireless 
network that has failed LEAP authentication.
The process takes place as follows:
1.
A client with a LEAP profile attempts to associate to access point A.
2.
Access point A does not handle LEAP authentication successfully, perhaps because the access point 
does not understand LEAP or cannot communicate to a trusted LEAP authentication server.
3.
The client records the MAC address for access point A and the reason why the association failed.
4.
The client associates successfully to access point B.
5.
The client sends the MAC address of access point A and the reason code for the failure to access 
point B.
6.
Access point B logs the failure in the system log.
Note
This feature does not need to be enabled on the client adapter or access point; it is supported 
automatically in the firmware of both devices. However, both the clients and access points must use 
these firmware versions or greater.
Upgrading to a New Firmware Release
Caution
To minimize the risk of a power failure during the firmware flashing process, which could render 
your client adapter inoperable, Cisco recommends that your computer be plugged into AC power or 
have a fully charged battery at the start of flashing. If a power failure does occur, follow the 
instructions in the 
“Obtaining Technical Assistance”
 section to contact TAC for assistance.
This section describes how to upgrade to client adapter firmware release 5.02.20 on a computer running 
Windows 98, 98 SE, NT, 2000, Me, or XP. Refer to the following document for instructions on upgrading 
the firmware on a Windows CE device:
