Software with WPA support if your wireless network uses host-based EAP authentication with WPA:

Funk Odyssey Client supplicant version 2.2 (for Windows 2000)

Windows XP Service Pack 1 and Microsoft support patch 815485 (for Windows XP)


Note Meetinghouse AEGIS Client supplicant version 2.1 is also supported for use with Windows 2000 and XP; however, it was not tested with this client adapter software release.


The Microsoft 802.1X supplicant, if your wireless network uses EAP-TLS, PEAP, or EAP-SIM authentication

If your wireless network uses PEAP authentication with a One-Time Password (OTP) user database:

SofToken version 1.3, 2.0, or greater from Secure Computing; SecurID version 2.5 from RSA; or hardware token from OTP vendors

Your software token PIN or hardware token password

If your wireless network uses EAP-SIM authentication:

PCSC-compliant smartcard reader installed in your computer's Type II or Type III PC card slot

Gemplus SIM+ smartcard inserted in the reader

The SIM card's PIN


Note The EAP-SIM supplicant included in the Install Wizard file supports only Gemplus SIM+ cards; however, an updated supplicant is available that supports standard GSM-SIM cards as well as more recent versions of the EAP-SIM protocol. The new supplicant is available for download from the ftpeng FTP server at the following URL:

ftp://ftpeng.cisco.com/ftp/pwlan/eapsim/CiscoEapSim.dll


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

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

If your computer is not connected to a DHCP server, 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

Access points to which your client adapter may attempt to authenticate must use the following firmware versions or greater: 12.00T (340, 350, and 1200 series access points) or Cisco IOS Release 12.2(4)JA (1100 series access points).


Note To use WPA or fast roaming (CCKM), access points must use Cisco IOS Release 12.2(11)JA or greater. To use radio management (RM), access points must use Cisco IOS Release 12.2(13)JA or greater.


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

Important Notes

Customized Installation Images (Notice to IT Professionals)


Caution Use caution when bundling the client adapter software into a customized installation image. If the registry settings are modified, the software may not install and uninstall properly.

Firmware Is Upgraded Automatically

The Install Wizard automatically upgrades the client adapter firmware to the version included in the Install Wizard file.


Note Applications such as AirMagnet and Wild Packets may fail after the firmware is upgraded. To resolve this problem, use ACU to downgrade the firmware to the previous version. Older versions of client adapter firmware are available from the Software Center on Cisco.com.


Uninstalling Software Components

All profiles are deleted if you use the Uninstall All Components option on the Cisco Aironet Wireless LAN Client Adapter Installation Wizard screen to uninstall the client adapter software. Cisco recommends that you use the Profile Manager's export feature to save your profiles before uninstalling the software.

Inserting and Removing Client Adapters

The following rules apply when inserting and removing client adapters:

If you start ACU while a client adapter of one radio type is inserted (such as a 340 series PC card) and then eject the card and replace it with a card of another radio type (such as a 350 series PC card), ACU displays "Your Wireless LAN Adapter is not inserted" until ACU is shut down and restarted.

The profiles for PC-Cardbus cards are tied to the slot in which the card is inserted. Therefore, you must always insert your PC-Cardbus card into the same slot, create profiles for both slots, or export the profiles for one slot and import them for the other slot.

New EAP-SIM Supplicant Available

A new EAP-SIM supplicant is available for download from the ftpeng FTP server. This new supplicant is an upgrade to the one included in the Install Wizard file. It provides new features, supports more recent versions of the EAP-SIM draft standard, and can be used with standard GSM-SIM cards as well as Gemplus SIM+ smartcards.

The new supplicant overwrites any previous EAP-SIM supplicant settings. If you plan to install the Cisco Aironet Install Wizard file after the new supplicant is installed, either perform an express installation or make sure the EAP-SIM option is not selected on the Custom Installation screen. Otherwise, the EAP-SIM supplicant included in the Install Wizard file overwrites the new supplicant's settings.

You can access the new EAP-SIM supplicant at the following URL:

ftp://ftpeng.cisco.com/ftp/pwlan/eapsim/CiscoEapSim.dl

WPA Migration Mode Not Supported by Clients

Although the software components included in client adapter Install Wizard version 1.2 support Wi-Fi Protected Access (WPA) authenticated key management for 350 series and CB20A cards on computers running Windows 2000 or XP (see the "WPA Support" section for more information), they do not include support for WPA migration mode.

In order to use Cisco Aironet client adapters with WPA, the access point must be configured only for the WPA TKIP cipher. The use of the following migration-mode-supporting ciphers is not supported by Cisco WPA clients:

TKIP + WEP128

TKIP + WEP40

To support the coexistence of Cisco Aironet WPA clients and non-WPA clients, it is necessary to configure separate VLANs and encryption policies on the access point. Specifically, a VLAN with TKIP encryption mode and a VLAN with a compatible WEP encryption mode specified would be required.


Note Refer to the documentation for your access point for specific instructions.


Windows Wireless Network Connection Icon Shows Unavailable Connection (Windows XP Only)

If your computer is running Windows XP and you configured your client adapter using ACU, the Windows Wireless Network Connection icon in the Windows system tray may be marked with a red X and show an unavailable connection even though a wireless connection exists. This condition is caused by a conflict between ACU and Windows XP's wireless network settings. Simply ignore the Windows icon and use the ACM icon to check the status of your client adapter's wireless connection.

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

Supporting Documentation

The Cisco Aironet 340, 350, and CB20A Wireless LAN Client Adapters Installation and Configuration Guide for Windows (part number OL-1394-07) pertains specifically to versions of the software that are included in Install Wizard version 1.2. If you are using, installing, or upgrading to previous versions of client adapter software, refer to a previous version of this manual for information and instructions.

New and Changed Information

Redesigned Network Security Screen

The Network Security screen in ACU has been redesigned to accommodate additional security features (see Figure 1).


Note Refer to Chapter 5 of the 340, 350, and CB20A Wireless LAN Client Adapters Installation and Configuration Guide for Windows (part number OL-1394-07) for instructions on enabling client security features using this new screen.


Figure 1 Network Security Screen

WPA Support

Wi-Fi Protected Access (WPA) is a standards-based, interoperable security enhancement that greatly increases the level of data protection and access control for existing and future wireless LAN systems. It is derived from and will be compatible with the upcoming IEEE 802.11i standard. WPA leverages Temporal Key Integrity Protocol (TKIP) and Michael message integrity check (MIC) for data protection and 802.1X for authenticated key management. WPA is supported by the Cisco Wireless Security Suite.

WPA supports two mutually exclusive key management types: WPA and WPA-Pre-shared key (WPA-PSK). Using WPA key management, clients and the authentication server authenticate to each other using an EAP authentication method, and the client and server generate a pairwise master key (PMK). The server generates the PMK dynamically and passes it to the access point. Using WPA-PSK key management, however, you configure a pre-shared key on both the client and the access point, and that pre-shared key is used as the PMK.

Only 350 series and CB20A cards that are installed on computers running Windows 2000 or XP and running LEAP or host-based EAP authentication can be used with WPA. Support for WPA is available in the software components included in Install Wizard version 1.2 or greater. However, if you want to use host-based EAP authentication with WPA, you must install additional software with WPA support. The following WPA software is recommended for use with Cisco Aironet client adapters:

Funk Odyssey Client supplicant version 2.2 (for Windows 2000)

Windows XP Service Pack 1 and Microsoft support patch 815485 (for Windows XP)


Note Meetinghouse AEGIS Client supplicant version 2.1 is also supported for use with Windows 2000 and XP; however, it was not tested with this client adapter software release.



Note Refer to Chapter 5 of the 340, 350, and CB20A Wireless LAN Client Adapters Installation and Configuration Guide for Windows (version OL-1394-07) for instructions on enabling WPA.



Note WPA must also be enabled on the access point. Access points must use Cisco IOS Release 12.2(11)JA or greater to enable WPA. Refer to the documentation for your access point for instructions on enabling this feature.

Radio Management Support

A new parameter entitled Enable Radio Management Support has been added to the Advanced (Infrastructure) Parameters screen in ACU. Checking this check box enables the access point to which the client adapter is associated to control the use of radio management (RM), provided RM is enabled on the access point.

RM is a system-wide feature that involves multiple infrastructure nodes and is a feature of the Cisco Structured Wireless-Aware Network (SWAN). The RM feature on the access point acts on radio measurement requests from other network devices to instruct the access point and its associated clients to perform required radio measurements and then report them.

Cisco SWAN uses RM data to provide:

Rogue access point detection and location

Interference detection to isolate and locate network interference

Assisted site surveys for simplified WLAN deployment processes

Air/radio frequency (RF) scanning and monitoring

Streamlined WLAN management and operations support

This parameter is available in ACU version 6.2 or greater and only for 350 series client adapters using firmware version 5.30.17 or greater.


Note Access points must use Cisco IOS Release 12.2(13)JA or greater to enable RM. Refer to the documentation for your access point for instructions on enabling this feature.


Ability to Disable Fast Roaming (CCKM)

In the previous client adapter release (Install Wizard version 1.1 and client adapter firmware version 5.20.17), fast roaming (CCKM) was enabled automatically by the client adapter firmware. Now, however, you can enable or disable fast roaming in ACU by checking or unchecking the Allow Fast Roaming (CCKM) check box on the Network Security screen.

New and Changed Status Fields

Three new status fields have been added to the Status screen in ACU:

Broadcast Encryption Type—Indicates the type of encryption that is being used for broadcast and multicast packets.

Value: None, WEP, TKIP, or CKIP

WPA Authentication—Indicates whether WPA is enabled on the client adapter and the access point to which it is associated.

Value: None or WPA

Fast Roaming—Indicates whether fast roaming is enabled on the client adapter.

Value: None or CCKM

Two status fields have been changed on the Status screen in ACU:

Using Message Integrity Check—This field has been renamed Message Integrity Check (MIC), and its possible values are now None, MMH, and Michael to reflect the MIC type.

None—MIC is disabled.

MMH—MIC is enabled and is being used with CKIP.

Michael—MIC is enabled and is being used with WPA and TKIP.

WEP (Wired Equivalent Privacy)—This field has been renamed Data Encryption Type, and its possible values are now None, WEP, TKIP, and CKIP to indicate the type of encryption that is being used for unicast packets.

New Statistics Fields

Three new statistics fields have been added to the Statistics screen in ACU:

WPA Mismatches—The number of probe responses or beacons received that do not qualify for association because of a mismatched WPA information element. WPA information elements are sent by access points to advertise supported authentication modes and supported ciphers. This field is displayed only if WPA is enabled.

RM Requests Received—The number of valid radio management (RM) request frames that were received successfully. This field is displayed only if RM is enabled.

RM Reports Transmitted—The number of radio management (RM) report frames that were generated and transmitted in response to a valid RM request. This field is displayed only if RM is enabled.

Other Changes

The following changes have also been made to the 340, 350, and CB20A client adapter software for Windows:

The Install Wizard version number now appears in the title bar of the Cisco Aironet Wireless LAN Client Adapter Installation Wizard screen (see Figure 2).

The Setup.exe file, which is extracted from the Install Wizard file, has been renamed IWSetup.exe.

The minimum value for the LEAP Authentication Timeout Value field on the LEAP Settings screen in ACU has changed from 45 seconds to 10 seconds.

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC Escalation Center. The type of support that you choose depends on the priority of the problem and the conditions stated in service contracts, when applicable.

We categorize Cisco TAC inquiries according to urgency:

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration. There is little or no impact to your business operations.

Priority level 3 (P3)—Operational performance of the network is impaired, but most business operations remain functional. You and Cisco are willing to commit resources during normal business hours to restore service to satisfactory levels.

Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively impacted by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Priority level 1 (P1)—An existing 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.
