Click the new firmware image (PC340-350vxxx.img).

Click the Open button to load the firmware image into your client adapter’s Flash memory.

This section describes resolved and open caveats for client adapter firmware release 4.25.5.

The following caveat is resolved by client adapter firmware release 4.25.5.

If the client adapter’s LEAP password is entered incorrectly, the client repeatedly tries to authenticate. 
However, the RADIUS server turns off the client’s account and disables the user from the system 
(CSCdu06254). This caveat is resolved in firmware release 4.25.5.

The following are known problems for client adapter firmware release 4.25.5.

When your client is not associated to an access point, it can take 5 minutes or longer to load new client 
firmware on Windows 2000 or Microsoft XP (CSCdu38757). No errors occur, just a delay.

The combination of client adapter firmware version 4.25.5 and ACU version 4.15.001 or 4.15.006 allows 
the user to configure a client adapter for LEAP authentication in ad-hoc mode. This configuration is 
illegal (CSCdu21973). Future releases of the client adapter firmware and ACU will disallow this 
combination.

When a client starts in ad-hoc mode, signal strength is 0. When a second client joins the cell, signal 
strength increases. When the second client leaves the cell, the signal strength stays the same even though 
it should return to 0 when no other clients are in the cell (CSCdu19772). This caveat will be resolved in 
a future release of the firmware.
