Introduction

This document describes system requirements, upgrade procedures, and caveats for Cisco Aironet PC-Cardbus client adapter firmware release 5.01.02. This release resolves the caveats listed in the "Resolved Caveats" section.

System Requirements

To install firmware version 5.01.02, you must have a Cisco Aironet 5-GHz 54-Mbps PC-Cardbus card (model number CB20A) and your computer must run Windows 98, 2000, Me, or XP.

Firmware release 5.01.02 must be used with Windows ACU version 5.03.009 or greater and Windows PC-Cardbus card driver version 3.4.19 or greater. To ensure compatibility of devices, your access points must use firmware version 11.56 or greater.


Note PC-Cardbus cards use different drivers and firmware than PC, LM, and PCI cards and mini PCI cards.


Network-EAP Authentication Requires Matching 802.1X Protocol Drafts

In order to use Network-EAP authentication on your wireless network, your client devices and infrastructure devices (access points and bridges) must use the same 802.1X protocol draft. For example, PC-Cardbus card firmware release 5.01.02 supports draft 10 of the 802.1X protocol standard. Therefore, if PC-Cardbus cards use this version of firmware, an access point or bridge to which they associate must also be configured to use draft 10. The table below lists firmware versions for Cisco Aironet products and the drafts with which they comply.

1 The functionality in draft 10 is equivalent to the functionality in draft 11, the ratified draft of the 802.1X standard.

2 The default draft setting in access point and bridge firmware version 11.06 and later is draft 10.

If your clients and infrastructure devices do not have matching 802.1X protocol drafts, upgrade the firmware in these devices to versions with the same draft number. However, if your access points or bridges are using firmware version 11.06 or later, you can use their Authenticator Configuration page to select the draft of the 802.1X protocol that they should use. To set the draft for your access points or bridges, follow the instructions in the Release Notes for your device.

Upgrading to a New Firmware Release

This section describes how to upgrade to PC-Cardbus card firmware release 5.01.02.


Note Currently the PC-Cardbus card is supported only with Windows 98, 2000, Me, and XP.


Determining the Firmware Version

To determine the firmware version that your PC-Cardbus card is currently using, follow the steps below.


Step 1 Open ACU on a computer running Windows 98, 2000, Me, or XP.

Step 2 Click the Status icon or select Status from the Commands drop-down menu. The firmware version is displayed on the Status screen.


Upgrading the Firmware

To upgrade your PC-Cardbus card's firmware on a computer running Windows 98, 2000, Me, or XP, follow the steps below.


Step 1 Perform one of the following:

If you are installing firmware from a bundled file on Cisco.com, follow the steps below:

a. Using Windows Explorer, find the folders that were extracted from the bundle and double-click the firmware folder (the one that doesn't specify ACU or the Windows operating system).

b. Go to Step 2.

If you are installing firmware from an individual file on Cisco.com, follow the steps below:

a. Use the computer's web browser to access the following URL:
http://www.cisco.com/public/sw-center/sw-wireless.shtml

b. Click the link for Cisco Aironet Wireless LAN Client Adapters.

c. Find the section for client adapter firmware.

d. Click the link that corresponds to your client adapter's model number (CB20A).

e. Select the latest firmware file for your client adapter.


Note The firmware for PC-Cardbus cards is labeled CB.



Note If your wireless network uses LEAP authentication, remember to select radio firmware of the same draft standard as the access points to which your client adapter will be authenticating. PC-Cardbus card firmware was first released at draft 10.


f. Read and accept the terms and conditions of the Software License Agreement.

g. Select the firmware file again to download it.

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

i. Find the file using Windows Explorer, double-click it, and extract the image file to a folder.

j. Go to Step 2.

Step 2 Make sure the client adapter is installed in your computer and is operational.

Step 3 Open ACU; click the Load Firmware icon or select Load New Firmware from the Commands drop-down menu. The Open window appears.

Step 4 Find the location of the new firmware in the Open Window's Look in box. The default location is InstallPath\Firmware, where InstallPath is the directory in which ACU was installed.

Step 5 Click the firmware image file (*.img) so that it appears in the File name box at the bottom of the Open window.

Step 6 Click the Open button. A progress bar appears while the selected image is loaded into the client adapter's Flash memory.

Step 7 Click OK when the "Firmware Upgrade Complete!" message appears. The OK button cannot be selected until the process is complete or an error occurs.


Caveats

This section describes resolved and open caveats for PC-Cardbus card firmware release 5.01.02.

Resolved Caveats

The following caveats are resolved in PC-Cardbus card firmware release 5.01.02.

PC-Cardbus Card Lacks Feature to Scan for a Better Access Point

The Periodically Scan For A Better Access Point feature is not available for PC-Cardbus cards (CSCdx81409). This caveat is resolved in PC-Cardbus card firmware release 5.01.02. This feature can now be selected on the RF Network screen in ACU.

ACU Shows Poor Beacons Received When Access Point Beacon Period Exceeds 1000

When the access point beacon period is greater than 1000 (1 second), ACU shows the beacons received as poor (CSCdy20384). If the access point's beacon period is set to a value greater than 1000 (1 second), you must change the client refresh interval to a value greater than 1 second to ensure that the client receives the beacons. This caveat is resolved in PC-Cardbus card firmware release 5.01.02.

Open Caveats

The following are known problems for PC-Cardbus card firmware release 5.01.02.

PC-Cardbus Card LEAP Authenticates Before User Credentials Are Entered

If the PC-Cardbus card uses a profile that specifies that you be automatically or manually prompted for the LEAP username and password and then the card is switched to another profile that also uses LEAP, the card authenticates automatically using the first profile's credentials, and you are not prompted to enter a new username and password (CSCdy19375, CSCdy21644, CSCdy23691, and CSCdy17899). To resolve this problem, reboot your computer.

Compaq Device Locks Up During FTP Transfers

The Compaq EVO N180 locks up while performing continuous FTP transfers (CSCdx81363). To work around this problem, reboot your computer. To completely resolve the problem, update to the latest BIOS version available from Compaq.
