Introduction

This document describes important notes, system requirements, upgrade procedures, new and changed information, and caveats for the following releases of Cisco Aironet client adapter software:

Version 2.20 of the Cisco Aironet client utilities for Windows CE

Version 2.20 of the Cisco Aironet client adapter driver for Windows CE

The client utilities, driver, and help files are released together in a single file entitled WinCE2.11-PCM-LMC-v2.20.exe (for Windows CE 2.11) or WinCE3.0-PCM-LMC-v2.20.exe (for Windows CE 3.0).

Important Notes


Note If your device is running Windows CE 3.0 version 2002 and your RADIUS server account specifies a domain, you must enter the domain name in the Wireless Login Module screen. To do so, enter the domain name before the username and separate the two with a forward slash (e.g., domain/username).



Note In the Site Survey Tool (SST) utility, the Percent Retries field on the Site Survey - Active Mode screen displays the percentage of packets that were retried for transmission. This value is calculated as follows: (number of retries x 100) / number of packets sent. If a lot of packets get lost, the number of retries could be greater than the number of packets sent. In this case, the Percent Retries field would show a value greater than 100%.


System Requirements

Client utility release 2.20 and driver release 2.20 can be used only with Cisco Aironet 340, 350, and 4800 Series Wireless LAN Client Adapters (PC cards and LM cards) and the following Windows CE devices:

Handheld PC (HPC) running Windows CE 2.11 with an ARM, StrongARM, Mips, SH3, SH4, or x86 processor

Handheld PC (HPC) running Windows CE 3.0 with an ARM, StrongARM, Mips, SH4, or x86 processor

Pocket PC (PPC) running Windows CE 3.0 with an ARM, StrongARM, Mips, or SH3 processor

Upgrading to a New Client Utility and Driver Release

This section describes how to upgrade to client utility release 2.20 and driver release 2.20 for
Windows CE.


Note The client utilities and help files are installed with the driver.


Uninstalling the Current Driver and Client Utilities

Cisco recommends that you uninstall the existing driver and client utilities for your client adapter before upgrading to more recent versions. This section provides instructions for uninstalling your client adapter's current driver and client utilities. The instructions vary depending on your client adapter's current driver version.

Uninstalling Driver Version 1.40 for Windows CE 2.11


Step 1 Terminate any Cisco Aironet applications running on the Windows CE device and eject the client adapter.

Step 2 Select Start > Programs > Cisco > Cisco Aironet Uninstall. The Cisco Aironet Uninstall screen appears.

Step 3 Select the Uninstall Cisco Aironet Wireless LAN Adapter checkbox.

Step 4 Click OK. The utility informs you that the adapter has been uninstalled. The registry entries (but no files) are removed.

Step 5 Delete the aironet.dll driver file and the following help files from the \Windows directory of the Windows CE device: AuthType.htm, CEM.htm, Cisco Setup.htm, ClieName.htm, DataRate.htm, DHCP.htm, InfrStru.htm, LEAP.htm, LeapLogin.htm, PSMode.htm, SSID.htm, TxPowe.htm, WEP.htm, and WorldMode.htm.

Step 6 Delete the following client utility files, which are probably in the \Windows\Programs\Cisco directory on the Windows CE device: Aironet Client Utility.exe, Cisco Aironet Uninstall.exe, Cisco Link Status.exe, Client Encryption Manager.exe, Client Statistics Utility.exe, Load New Firmware.exe, and Site Survey Tool.exe.

Step 7 Delete the Cisco directory from \Windows\Programs.

Step 8 Go to the "Loading a New Driver and Client Utilities" section for instructions on loading the new driver and client utilities.


Uninstalling Driver Version 1.50 or Later for Windows CE 2.11 or 3.0


Step 1 Eject the client adapter and remove it from the Windows CE device.

Step 2 Select Start > Settings > Control Panel > Remove Programs (on an HPC device) or Start > Settings >
System tab > Remove Programs (on a PPC device).

Step 3 Select Cisco Wireless LAN Adapter.

Step 4 Click Remove.

Step 5 When asked to verify your decision to remove the adapter, click Yes.

Step 6 Click OK. The driver, client utilities, registry entries, and Cisco directory are removed.

Step 7 Go to the "Loading a New Driver and Client Utilities" section for instructions on loading the new driver and client utilities.


Loading a New Driver and Client Utilities

Follow the instructions below to install driver version 2.20 and client utility version 2.20 for your client adapter.


Step 1 Make sure that the client adapter is removed from the Windows CE device.

Step 2 Use a serial or USB cable to connect your Windows CE device to a laptop or PC running Microsoft ActiveSync. A message appears on the Windows CE device indicating that it is connecting to the host. After the Windows CE device is connected, the New Partnership window appears on the laptop or PC. This window asks if you want to set up a partnership.


Note Cisco recommends that you install the latest version of ActiveSync.


Step 3 Perform one of the following:

If you want to establish a partnership that allows you to synchronize files between the laptop or PC and the Windows CE device, select Yes, click Next, and follow the instructions on the screen to specify the files to be synchronized and to finish setting up the partnership.

If you do not want to synchronize files and want to connect as a "guest," select No and click Next. The screen indicates that you are connected as a guest.

Step 4 Use the laptop or PC's web browser to access the following URL:

http://www.cisco.com/public/sw-center/sw-wireless.shtml

Step 5 Locate the section for client adapter drivers and utilities.

Step 6 Click the link for Windows CE 2.11 or 3.0, depending on which version of Windows CE your device is running.

Step 7 Select the WinCE2.11-PCM-LMC-v2.20.exe or WinCE3.0-PCM-LMC-v2.20.exe file.

Step 8 Read and accept the terms and conditions of the Software License Agreement.

Step 9 Select the WinCE2.11-PCM-LMC-v2.20.exe or WinCE3.0-PCM-LMC-v2.20.exe file to download it.

Step 10 Save the file to a floppy disk or to the hard drive of your laptop or PC.

Step 11 Use Windows Explorer to locate the saved file.

Step 12 Double-click the *.exe file for your version of Windows CE (WinCE2.11-PCM-LMC-v2.20.exe or WinCE3.0-PCM-LMC-v2.20.exe). The application creates an Install directory under the ActiveSync directory, extracts the .cab files contained in the *.exe file, and copies them to the Install directory.

Step 13 Click Next to start the Windows CE Application Manager (CeAppMgr). CeAppMgr interrogates the Windows CE device to determine its processor type.


Note If a Windows CE device is not connected to the laptop or PC (as instructed in Step 2), click Exit to quit the setup program and connect a Windows CE device or click Next to continue the installation. If you select Next, a message appears indicating that the software will be downloaded the next time a mobile device is connected. Click OK. The next time a Windows CE device is connected to the laptop or PC via ActiveSync, CeAppMgr starts automatically, and you are prompted to install the software. If you select Exit, click OK to shut down CeAppMgr and start again beginning with Step 1.


Step 14 When a dialog box appears asking if you want to install the client adapter using the default application installation directory, click Yes. The default directory is \Windows\Programs\Cisco on HPC devices or \Windows\Start Menu\Programs\Cisco on PPC devices.


Note If you click No on an HPC device, CeAppMgr transfers the *.cab file to the Windows CE device and executes it. This process takes awhile and shows no evidence of activity. Eventually a screen appears on the Windows CE device that asks you where the application files should be installed.


A message and a progress bar appear indicating that the client adapter is being installed. CeAppMgr copies the processor-specific *.cab file to the Windows CE device. Then the driver and help files are copied to the \Windows directory, and the client utilities are installed in the \Windows\Programs\Cisco directory on HPC devices or the \Windows\Start Menu\Programs\Cisco directory on PPC devices. Shortcuts to ACU and CEM are automatically added to the desktop on HPC devices.

Step 15 When the installation process is complete on the laptop or PC, a message appears asking you to check the screen of the Windows CE device to see if any additional steps are required to complete the installation. Click OK to terminate the installation process on the laptop or PC.

Step 16 Complete any required steps on the Windows CE device.

Step 17 Disconnect the Windows CE device.

Step 18 Insert the client adapter (with the Cisco logo facing up) into the PC card slot of the Windows CE device.

The Windows CE device should configure the client adapter, and the green LED on the adapter should blink. If this does not happen, remove the client adapter, reset the Windows CE device, and reinsert the client adapter.

Step 19 The Cisco Wireless LAN Adapter Settings dialog box appears. (If the dialog box does not appear, select Start, Settings, Control Panel, Network, the Adapters tab, the Cisco Aironet wireless LAN adapter, and Properties on HPC devices or Start, Settings, the Connections tab, Network, and the Cisco Aironet wireless LAN adapter on PPC devices.)

Perform one of the following:

If your device is connected to a DHCP server, select Obtain an IP address via DHCP or Use server-assigned IP address and click OK.

If your device is not connected to a DHCP server, select Specify an IP address or Use specific IP address and follow the steps below:

a. Enter the IP address, subnet mask, and default gateway address you want to assign to your device. They can be obtained from your system administrator.

b. Select the Name Servers tab and enter the primary and secondary DNS and WINS you want to assign to your device. They can be obtained from your system administrator.

c. Click OK.

Step 20 Double-click the Cisco ACU icon or select Start > Programs > Cisco > Aironet Client Utility to open ACU.

Step 21 Select SSID under Property. Enter your RF network's case-sensitive SSID in the Value box.

Step 22 Select Client Name under Property. Enter your Windows CE device's unique client name in the Value box.

Step 23 Select Data Rates under Property. Make sure that Auto is selected in the list of options in the Value box.

Step 24 Click OK. The driver and client utility installation is complete. If the installation was successful, the client adapter's green LED blinks.


Note Refer to the Cisco Aironet Wireless LAN Client Adapters Installation and Configuration Guide for Windows CE for information on configuring your client adapter.



New and Changed Information

This section describes new and changed information for client utility release 2.20 and driver release 2.20 for Windows CE.

Support for HPC Devices with SH4 Processors

The Cisco Aironet client adapter driver and utilities for Windows CE 3.0 now support handheld PCs (HPCs) with SH4 processors.

Support for Message Integrity Check (MIC)

Windows CE driver version 2.20 supports MIC, a new security feature designed to prevent sophisticated attacks on your wireless network's WEP keys. MIC does not need to be enabled on the client adapter; it is supported automatically in the driver version listed above. However, it must be enabled on the access point.

MIC prevents bit-flip attacks on encrypted packets. During a bit-flip attack, an intruder intercepts an encrypted message, alters it slightly, and retransmits it, and the receiver accepts the retransmitted message as legitimate. MIC adds a few bytes to each packet to make the packets tamper-proof.

The ACU screen displays the word "(MIC)" next to the current status if MIC is supported by the client adapter's driver and is enabled on the access point. If MIC is enabled, MIC statistics are provided by the Client Statistics Utility (CSU).


Note Access point firmware version 11.10T or greater is required to enable MIC. Refer to the Cisco Aironet Access Point Software Configuration Guide for instructions on enabling MIC on the access point.



Note If you enable MIC on the access point, your client adapter's driver must support MIC; otherwise, the client will not be able to associate.


Caveats

This section describes resolved and open caveats for client utility release 2.20 and driver release 2.20 for Windows CE.

Resolved Caveats

The following caveats are resolved in client utility release 2.20 and driver release 2.20.

WLM Fails to Run After Device Is Reset

If the Windows CE device is reset, the Wireless Login Module (WLM) utility terminates before the user can enter the LEAP username and password (CSCdv61350). This caveat is resolved in driver release 2.20.

LEAP Password Is Visible During Entry

The LEAP password is visible during entry when auto-complete is used (CSCdw03552). This caveat is resolved in client utility release 2.20.

Open Caveats

The following are known caveats for client utility release 2.20 and driver release 2.20.

Screen Flickers When Client Adapter Uses Max PSP Mode

The screen of the Windows CE device flickers when the client adapter is set to operate in Max PSP mode (CSCdw03420). This caveat will be resolved in a future release.

Overlapping Icons in the Cisco Folder

After you install the driver and client utilities, the icons for the utilities overlap one another in the Cisco folder (CSCdw03461).

Incorrect Error Message Displays If ActiveSync Is Not Installed on the Laptop or PC

If you double-click the WinCE2.11-PCM-LMC-vx.xx.exe or WinCE3.0-PCM-LMC-vx.xx.exe file to install the latest version of the Windows CE driver and client utilities but ActiveSync is not installed on the laptop or PC to which the Windows CE device is connected, a message appears indicating that the ceutil.dll file cannot be found. However, the message should read, "Windows CE Services not found on this computer. Setup cannot continue and will now exit" (CSCdv50211).

Click OK to acknowledge the message and terminate the installation utility. Then install ActiveSync on the laptop or PC and start the driver installation procedure again.


Note ActiveSync can be obtained from the CD that shipped with your Windows CE device, from the device manufacturer, or from Microsoft; however, Cisco recommends that you install the latest version of ActiveSync.
