Important Notes

Not Supported on Windows CE, Linux, and Mac OS Operating Systems

Client adapter firmware 5.41.00 is not supported for use on Windows CE, Linux, and Mac OS 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 fill out a form to receive authorization to download encrypted software. Registered Cisco.com users are required to fill out the form only once, but 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 at the following URL:

http://www.cisco.com/cgi-bin/Software/Crypto/crypto_main.pl

Upgrading to a New Firmware Version


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 5.41.00 on a computer running the Windows 2000 or XP operating system.

Finding the Firmware Version

To find the firmware version that your client adapter is currently using, open ACU and click the Status icon. The Firmware Version field on the Status screen shows the firmware version.

Upgrading the Firmware

Follow these steps to upgrade your client adapter's firmware to version 5.41.00.


Note When you upgrade your client adapter's firmware using ACU, the Automatically Load New Firmware When NDIS Driver Is Updated parameter on the Aironet Client Utility Preferences screen becomes disabled (or unchecked) automatically to prevent the newly loaded firmware from being overwritten by the driver. If you ever want to enable this parameter, you must recheck the check box.



Step 1 Use the computer's web browser to access the following URL:

http://www.cisco.com/public/sw-center/sw-wireless.shtml

Step 2 Choose Option #2: Aironet Wireless Software Display Tables.


Note You can download software from the Software Selector tool instead of the display tables. To do so, choose Option #1: Aironet Wireless Software Selector, follow the instructions on the screen, and go to Step 7.


Step 3 Click Cisco Aironet Wireless LAN Client Adapters.

Step 4 Under Individual Files, find the client adapter firmware.

Step 5 Click the link that corresponds to your client adapter's model number (such as 350 series).

Step 6 Click 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 Complete the encryption authorization form; then read and accept the terms and conditions of the Software License Agreement.

Step 8 Click 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 in which you want the file to be placed, and click OK and Unzip. After the file is 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.

Step 16 Click OK when the "Firmware Upgrade Complete!" message appears. The OK button cannot be selected until the process is complete or an error occurs.


Resolved Caveats

The following caveats are resolved in client adapter firmware 5.41.00.

CSCed75714—WPA client may take up to 5 minutes to associate to 11g access point

The client adapter may take up to 5 minutes to associate to an 802.11g access point when the following settings are enabled: WPA or WPA-PSK, IP phone QoS element, and low power (less than 100 mW).

CSCin51159—ACU Status screen and ACM Connection Status screen may display incorrect SSID

If your client adapter is configured with multiple profiles, the ACU Status screen and ACM Connection Status screen may incorrectly display the SSID of a profile that is not is use. However, the functionality of your client adapter is not affected.

Getting Bug Information on Cisco.com

If you are a Cisco registered user, you can use the Cisco TAC Software Bug Toolkit, which consists of three tools (Bug Navigator, Bug Watcher, and Search by Bug ID Number) that help you to identify existing bugs (or caveats) in Cisco software products.

Opening a TAC Case

Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

http://www.cisco.com/tac/caseopen

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55

TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—Your network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
