In Windows CE
Select Start > Programs > Cisco > Load New Firmware. The firmware version is displayed in the Select New Firmware screen.
In Linux
Select Status from the Commands pull-down menu in ACU. The firmware version is displayed in the Status screen.
In Macintosh
Select Status from the File pull-down menu in the Macintosh client utility and then the Link Status tab. The firmware version is displayed in the Status screen.
Upgrade Procedure
For instructions on upgrading your current version of Cisco Aironet client adapter firmware, follow the steps below:
Step 1 Go to www.cisco.com and select Technical Documents > Documentation Home Page > Broadband/Wireless Solutions > Aironet 350 Series Wireless LAN Products > Cisco Aironet 350 Series Wireless LAN Adapters > Cisco Aironet Wireless LAN Adapters Software Configuration Guide.
Step 2 Select one of the following links, depending on your operating system:
•For Windows 95, 98, NT, 2000, or Me or Linux, select Using the Aironet Client Utility.
•For Windows CE, select Using the Client Utilities for Windows CE.
•For Macintosh, select Using the Client Utility for MacOS 9.x.
Step 3 Follow the instructions for loading new firmware.
New Features in Firmware Release 4.13
This section describes new features in firmware release 4.13.
Support for Cisco Aironet 350 Series Radio Hardware
This firmware release supports Cisco Aironet 350 series radio hardware.
EAP and LEAP Authentication
Extensible Authentication Protocol (EAP) and LEAP (also referred to as EAP-Cisco Wireless) perform mutual authentication of the client and Cisco Secure RADIUS server.
Limitations or Restrictions
•The minimum firmware version required for LEAP support is 4.13.
•Access Point firmware release 11.00 is the minimum version required to support this feature. Release 11.00 is the first version of firmware that enables the Access Point to be configured as an EAP or LEAP authenticator.
•The Access Point requires an EAP authenticator. The RADIUS server must support the type of authentication you are using (either EAP or LEAP).
Caveats
This section describes known problems for client adapter firmware release 4.13.
Open Caveats
If a client adapter is associated to an Access Point that is configured for open authentication, LEAP authentication, and full encryption and the client has a WEP key stored in NVRAM, it is possible for the client to communicate with the Access Point using the incorrect WEP key (CSCds79736).
This problem can occur after the following sequence:
1. LEAP authentication is enabled on the client.
2. The client associates to the Access Point and is authenticated with LEAP.
3. LEAP is then disabled on the client, but WEP remains enabled.
4. When the client reassociates with the Access Point, it incorrectly uses the key in working memory (the key used during LEAP authentication) instead of using the key stored in NVRAM.
You must force the client to use the key in NVRAM by either rebooting the client or by ejecting and then reinserting the client adapter.
