Introduction
This document describes system requirements, upgrade procedures, features, and caveats for Cisco Aironet PC-Cardbus client adapter firmware release 4.99.
System Requirements
To install firmware version 4.99, you must have a Cisco Aironet PC-Cardbus card (model number CB20A) and your computer must run Windows 98, 2000, Me, or XP.
Firmware release 4.99 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 between devices, your access points must use firmware version 11.50T or greater.
Note
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 4.99 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 access point.
Upgrading to a New Firmware Release
Cisco Aironet's PC-Cardbus cards begin shipping with firmware version 4.99. Therefore, you do not need to install or upgrade your card's firmware for this release. Instructions for upgrading to future PC-Cardbus card firmware releases will be provided in the Release Notes that accompany those releases.
Features
Firmware release 4.99 is the first firmware version to support Cisco Aironet's IEEE 802.11a-compliant 54-Mbps 5-GHz PC-Cardbus card. This release supports all of the features included in the latest firmware releases for PC, LM, and PCI cards (version 4.25.30) and mini PCI cards (version 5.00.03) except the following RF Network parameters: Use Short Radio Headers, World Mode, Periodically Scan For A Better Access Point, and Clear Channel Assessment.
Caveats
Open Caveats
This section describes known problems for firmware release 4.99.
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, install BIOS version 0F12 or greater in your EVO N180 device.
Client Adapter LEAP Authenticates Before User Credentials Are Entered
If the client adapter uses a profile that specifies that you be automatically or manually prompted for the LEAP username and password and then the client adapter is switched to another profile that also uses LEAP, the client adapter authenticates automatically using the first profile's credentials, and you are not prompted to enter a new username and password (CSCdy19375, CSCdy21644, and CSCdy23691). To resolve this problem, reboot your computer.
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.
