Introduction

This document describes system requirements, important notes, new and changed information, and upgrade procedures for Cisco Aironet client adapter firmware version 5.20.17.

System Requirements

You need the following in order to install client adapter firmware version 5.20.17:

One of the following Cisco Aironet client adapters:

340 or 350 series PC, LM, or PCI card

350 series mini PCI card

PC-Cardbus (CB20A) card

A computer running one of the following operating systems:

Windows 98, 98 SE, NT, 2000, Me, or XP

Windows CE 3.0, 4.0, or 4.1

The following client adapter software for your computer's operating system:

Install Wizard version 1.1 for Windows, which includes PC, LM, and PCI card driver version 8.3; mini PCI and PC-Cardbus card driver version 3.5; ACU version 6.1; ACM version 2.1; 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 software versions or greater: firmware version 12.00T (340, 350, and 1200 series access points) or IOS release 12.2(4)JA (1100 series access points).


Note To use the fast secure roaming feature supported in client adapter firmware version 5.20.17, access points must use IOS release 12.2(11)JA or greater.


Important Notes

Not Supported on Linux and Mac OS Operating Systems

Client adapter firmware version 5.20.17 is not supported for use on 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

New and Changed Information

This section describes new and changed information for Cisco Aironet client adapter firmware version 5.20.17.

Support for Fast Secure Roaming

Some applications that run on a client device may require fast roaming between access points. Voice applications, for example, require seamless roaming to prevent delays and gaps in conversation. Support for fast secure roaming is now available for LEAP-enabled clients in client adapter firmware version 5.20.17.

During normal operation, LEAP-enabled clients mutually authenticate with a new access point by performing a complete LEAP authentication, including communication with the main RADIUS server. However, when you configure your wireless LAN for fast secure roaming, LEAP-enabled clients securely roam from one access point to another without the need to reauthenticate with the RADIUS server. Using Cisco Centralized Key Management (CCKM), an access point that is configured for wireless domain services (WDS) uses a fast rekeying technique that enables client devices to roam from one access point to another in under 150 milliseconds (ms). Fast secure roaming ensures that there is no perceptible delay in time-sensitive applications such as wireless Voice over IP (VoIP), enterprise resource planning (ERP), or Citrix-based solutions.

This feature does not need to be enabled on the client adapter; it is supported automatically in client adapter firmware version 5.20.17. However, it must be enabled on the access point.


Note IOS release 12.2(11)JA or greater is required to enable fast secure roaming on the access point. Refer to the documentation for your access point for instructions on enabling this feature.



Note If the Microsoft 802.1X supplicant is installed on your computer, you must disable one or two Windows parameters in order for this feature to operate correctly. Refer to the "Enabling LEAP" section of the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows (version OL-1394-06) for details.


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 version 5.20.17 on a computer running Windows 98, 98 SE, NT, 2000, Me, or XP.


Note Refer to the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows CE (version OL-1375-03) for instructions on upgrading the firmware on a Windows CE device. This document is at the following URL:
