–Windows CE 3.0, 4.0, or 4.1
•The following client adapter software for your computer's operating system:
–Install Wizard version 1.0 for Windows, which includes PCM/LMC/PCI card driver version 8.3, mini PCI and PC-Cardbus card driver version 3.5, ACU version 6.0, ACM version 2.0, LEAP security module version 6.0, PEAP security module version 1.01, and EAP-SIM security module version 1.0
–Driver and client utility version 2.30 for Windows CE
•To ensure compatibility between wireless devices, access points to which your client adapter may attempt to authenticate must use the following firmware versions or greater: 12.00T (340, 350, and 1200 series access points) or 12.2(4)JA (1100 series access points).
No Support for Linux and Mac OS
Firmware release 5.02.20 is not supported for use on Linux and Mac operating systems.
Cisco Aironet Software Requires Completion of Encryption Authorization Form
In order to access Cisco Aironet software from the Software Center on Cisco.com, you must now fill out a form to receive authorization to download encrypted software. Registered Cisco.com users are required to fill out the form only once while public users must do so once each session, each time software is downloaded. A form is automatically created for public users. The form for registered Cisco.com users is located at the following URL:
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:

Step 6 Select the latest firmware file for your specific client adapter type (such as CB or MPI).
Note The firmware for PC, LM, and PCI cards is labeled PCMCIA-LMC-PCI, the firmware for mini PCI cards is labeled mini PCI or MPI, and the firmware for PC-Cardbus cards is labeled CB.
Step 7 Read and accept the terms and conditions of the Software License Agreement.
Step 8 Select the firmware file again to download it.
Step 9 Save the file to a floppy disk or to your computer's hard drive.
Step 10 Find the file using Windows Explorer, double-click it, and extract the image file to a folder.
Note To extract the file, click Browse on the WinZip Self-Extractor screen, select the folder where you want the file to placed, click OK and Unzip. After the file has been extracted, click OK to close the screen.
Step 11 Make sure the client adapter is installed in your computer and is operational.
Step 12 Open ACU and click the Load Firmware icon. The Load New Firmware screen appears (see Figure 1).
Figure 1 Load New Firmware Screen
Step 13 Find the location of the new firmware in the Look in box.
Step 14 Click the firmware image file (*.img) so that it appears in the File name box at the bottom of the screen.
Step 15 Click the Open button. A progress bar appears while the selected image is loaded into the client adapter's Flash memory.

Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two levels of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The avenue of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.
•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.
Cisco TAC Website
You can use the Cisco TAC website to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC website, go to this URL:
All customers, partners, and resellers who have a valid Cisco service contract have complete access to the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website require a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to this URL to register:
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco TAC website, you can open a case online at this URL:
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC website so that you can describe the situation in your own words and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.
