Introduction

This document describes system requirements, important notes, new and changed information, installation and upgrade procedures, an caveats for CB21AG and PI21AG client adapters on computers that are running the Windows Vista operating system.

System Requirements

You need the following items in order to install and use the software:

One of the following Cisco Aironet client adapters:

CB21AG PC-Cardbus card.

PI21AG PCI card.


Note Cisco does not support the use of this client adapter software on anything but the CB21AG PC-Cardbus card or the PI21AG PCI card.


A computer with a 1-GHz 32-bit (x86) or 64-bit (x64) processor.

Windows Vista Service Pack 1 or Windows Vista with Microsoft KB932063 and KB935222 hotfixes. The software supports Windows Vista Business, Enterprise, and Ultimate operating systems.

40 GB hard drive with at least 15 GB of available space.

1 GB of system memory.

EAP versions:

EAP-FAST verion 2.2.9

PEAP version 1.1.2

LEAP version 1.0.15

If your wireless network uses EAP-TLS or PEAP authentication, you need Certificate Authority (CA) and user certificates for EAP-TLS authentication or CA certificate for PEAP authentication.

If your wireless network uses PEAP (EAP-GTC) authentication with a One-Time Password (OTP) user database, you need the following:

A hardware token device from OTP vendors or the Secure Computing SofToken program (2.1 or later).

Your hardware or software token password.

All necessary infrastructure devices (such as access points, servers, gateways, user databases, etc.) properly configured for any authentication type you plan to enable on the client.

The following information from your system administrator:

The logical name for your workstation (also referred to as client name).

The protocols necessary to bind to the client adapter, such as TCP/IP.

The case-sensitive service set identifier (SSID) for your RF network.

If your network setup does not include a DHCP server, you need the IP address, subnet mask, and default gateway address of your computer.

The wired equivalent privacy (WEP) keys of the access points with which your client adapter will communicate, if your wireless network uses static WEP for security

The username and password for your network account

Protected access credentials (PAC) file if your wireless network uses EAP-FAST authentication with manual PAC provisioning

If you want the client adapter to use Management Frame Protection (MFP), you need to run software release 4.1.181 or later on the Wireless LAN Controller.

Important Notes

EAP-FAST with EAP-GTC as Authentication Method

For single sign-on to work when an EAP-FAST profile is used and the selected authentication method is EAP-GTC, you must check the Cache user information for subsequent connections to this network check box, which is in the Security tab. The credentials pop-up dialog box appears with the first authentication.

Installing or Upgrading Client Adapter Software

Caveats

This section describes the open and resolved caveats for the software components in this release.

Open Caveats

The following caveats are open in release 1.0:

CSCsl63780—The client adapter sometimes sends an invalid radio measurement report to a requesting access point

In an environment with multiple access points, when an access point requests a radio measurement report, the client sometimes sends a report with invalid information.

Workaround: None.

CSCsm04853—The data rate of a client adapter exceeds the amount that an access point allows

An access point is configured to support a maximum data rate of 6 Mbps, but the client adapter shows a data rate of up to 54 Mbps.

Workaround: None.

CSCsm13393—CCKM appears as a security option for an ad hoc profile

The Cisco Centralized Key Management (CCKM) option appears for an ad hoc profile, but an ad hoc network cannot support CCKM security.

Workaround: Do not select the CCKM option for an ad hoc profile.

CSCsm81258—Walkabout failed while doing radio monitoring

After roaming to multiple access point and performing radio monitoring, there is not radio monitoring data available in the WLSE fault reporting function for radio management calculations.

Workaround: None.

CSCso76030—WPA with TKIP fails in an older hardware version

WPA with LEAP, PEAP-GTC, and EAP-FAST fails authentication with hardware version 74-3481-02.

Workaround: If you have an older adpater and encounter this behavior, use WPA2 with AES.

CSCso86001—When FTP is running, unplugging the client adapter causes operating system blue screen

The client adapter is configured with a profile that uses 802.1X with LEAP authentication. After an FTP session is established, the adapter is unplugged. The computer must be rebooted after the operating system blue screen appears.

Workaround: Do not unplug the client adapter when in heavy traffic conditions.

CSCso99074—The client remains associated with an access point even when the access point does not have sufficient capacity

The client is associated with an access point. The access point then rejects the client. The client does not roam to another access point but instead stays with the first access point.

Workaround: None.

CSCsq03569—The client does not reassociate with the access point after manual deauthentication

A controller is configured so that Management Frame Protection (MFP) is optional on the wireless LAN. The client associates with WPA2 with MFP and AES-CCMP. The controller shows that the client has negotiated MFP successfully. After the controller issues a deauthentication frame to the client, however, the client does not reassociate successfully.

Workaround: Reattempt to reconnect using the same profile.

CSCsq03578—The client does not reassociate with the access point after the access point sets client MFP to none

The client does not reassociate successfully after the access point sets client MFP from optional to none.

Workaround: Reattempt to reconnect using the same profile.
