Important Notes

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

Client adapter firmware 5.60.21 is not supported for use with Windows CE, Linux, and Mac OS operating systems.

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 5.60.21 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 5.60.21.


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://tools.cisco.com/support/downloads/pub/MDFTree.x?butype=wireless

Step 2 Click Wireless LAN Access.

Step 3 Click Cisco Wireless LAN Client Adapters.

Step 4 Click Cisco Aironet Wireless LAN Client Adapters.

Step 5 Click Cisco Aironet 350 Mini-PCI Wireless LAN Client Adapter, Cisco Aironet 350 Wireless LAN Client Adapter, or Cisco Aironet 5 GHz 54 Mbps Wireless LAN Client Adapter (CB20A).

Step 6 Click Aironet Client Firmware.

Step 7 Click Windows 2000 or Windows XP.

Step 8 Click 5.60.21.

Step 9 Click the executable file (*.exe) that appears on your screen.

Step 10 Click Download.

Step 11 Read the software download rules and click Agree.

Step 12 Save the file to a floppy disk or to your computer's hard drive.

Step 13 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 14 Make sure the client adapter is installed in your computer and is operational.

Step 15 Open ACU and click the Load Firmware icon. The Load New Firmware screen appears (see Figure 1).

Figure 1 Load New Firmware Screen

Step 16 Find the location of the new firmware in the Look in box.

Step 17 Click the firmware image file (*.img) so that it appears in the File name box at the bottom of the screen.

Step 18 Click the Open button. A progress bar appears while the selected image is loaded into the client adapter's Flash memory.

Step 19 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 5.60.21.

CSCei14830—CB20A hangs when using fast roaming and an SSID of more than 16 characters

If you configure an infrastructure access point with an SSID containing more than 16 characters and then configure a CB20A client adapter with the same SSID and enable fast roaming, the client adapter associates to the access point. However, the client hangs when the access point's dot11 interface is closed and then reopened.

CSCei27491—Client experiences Max PSP issues

When the client adapter is using Max PSP mode, it may fail to get a DHCP IP address and may experience low UDP throughput.

CSCsa81143—MIC mismatch errors for CCKM with CMIC/CKIP

Message integrity check (MIC) mismatch errors occur when the client is roaming between access points, the RF coverage is very poor, and Cisco Centralized Key Management (CCKM) is configured with CMIC/CKIP encryption. These errors tend to occur at the very edge of the cell when the client could be roaming between two or more access points.

CSCsb47648—Client cycles between association and disassociation

A 350 series client adapter running 5.60.xx firmware may cycle between association and disassociation with some third-party access points. In some cases, this may result in the link being unusable.

CSCsb90261—Clients fail to associate to some third-party access points

350 series client adapters running 5.60.08 or 5.60.17 firmware may be unable to associate to some third-party access points. The problem may result from the client adapter sending its association request frame with WME and RM information elements, even if the access point's beacons/probe responses have indicated that the access point does not support these features.

CSCsb97784—Client sends IP address 0.0.0.0 in response to show dot11 network-map command

350 series client adapters do not provide their IP address to the access point when the administrator issues the show dot11 network-map command. However, the client adapters do show the correct IP address when the administrator issues the show dot11 association command.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—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.

Severity 2 (S2)—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.

Severity 3 (S3)—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.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
