Note Client adapter utility and driver release 2.72 is not supported for use with Cisco Aironet 340 series client adapters.


Client adapter firmware version 5.60.21 (recommended)

Laptop or PC running a Windows operating system and Microsoft ActiveSync

ActiveSync connection (which can be serial, USB, etc.) to the Windows CE device

A PPC 2002, PPC 2003, or Windows CE .NET 4.2 device, if your wireless network uses EAP-FAST, EAP-TLS, or PEAP authentication

Certificate Authority (CA) and user certificates for EAP-TLS authentication or CA certificate for PEAP authentication

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

The hardware token from an OTP vendor

Your hardware token password

The following information from your system administrator:

The logical name for your Windows CE device (also referred to as client name)

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

The primary and secondary Domain Name System (DNS) and Windows Internet Name Service (WINS) to be assigned to your Windows CE device

If your network setup does not include a DHCP server, the IP address, subnet mask, and default gateway address to be assigned to your device

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

Your username and password for LEAP, EAP-FAST, or PEAP authentication, if your wireless network uses one of these authentication types

Your username for EAP-TLS authentication, if your wireless network uses EAP-TLS authentication

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

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

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

Important Notes

Support for Earlier CE Devices

Although this release can be installed on earlier CE devices and might work properly for most applications, no testing was performed for these earlier devices. Cisco cannot guarantee complete functionality. Cisco will not support or address any issues that arise from installing this release on those devices.

Recommended Firmware Version

Client adapter firmware version 5.60.21 is recommended for use with client utility and driver release 2.72 for Windows CE. If your client adapter is using a previous firmware version, follow the instructions in the Cisco Aironet 350 Series Wireless LAN Client Adapters Installation and Configuration Guide for Windows CE (part number OL-1375-05) to upgrade the firmware after installing client utility and driver release 2.72.

Delay in Windows CE DHCP Handler

A delay in the Windows CE DHCP handler prevents a device from recovering in less that 15 seconds.

GTK2 Packet Not Transmitted by PSC Handheld Device

If you turn a PSC handheld device on and off several times at a rapid rate, the device can still associate, but it cannot authenticate. The client device does not obtain an IP address and cannot function. If the device is in such a state, wait a few seconds in the On state and then powercycle the device.

Microsoft PEAP Issue for PPC 2002 Devices

Microsoft PEAP may not function properly on PPC 2002 devices.

Microsoft PEAP and Fast Reconnect

Microsoft PEAP does not support fast reconnect. Any interruption to the session requires the user to re-enter his or her credentials.


Note The ACS backend server cannot be configured for fast reconnect.


Recommendation for EAP-TLS

Cisco recommends connecting Windows CE devices to an EAP-TLS network only when the devices have the proper certificate import tools for your network.


Note These certificate import tools are not necessarily provided by Cisco.


Using Client Adapters with Both Windows and Windows CE Devices

After you install Cisco Aironet client adapter Install Wizard 1.0 or later on a Windows computer, the firmware of any client adapter that is inserted into that computer may be automatically upgraded to the version included in the Install Wizard file. If you insert a client adapter that has been upgraded to firmware version 5.02.19 or later into a Windows CE device, the adapter functions only if the device is running client utility and driver release 2.30 or later for Windows CE.

Supporting Documentation

Version OL-1375-05 of the Cisco Aironet 350 Series Wireless LAN Client Adapters Installation and Configuration Guide for Windows CE pertains specifically to client utility and driver releases 2.60, 2.70, and 2.72. If you are using, installing, or upgrading to an older release of client adapter software, refer to a previous version of this manual for information and instructions.

New and Changed Information

Support for Additional Platform

Client utility and driver release 2.72 supports one new Windows CE .NET platform: ARMv4I.

Support for WPA-PSK

Wi-Fi Protected Access (WPA) supports two mutually exclusive key management types: WPA and WPA-Pre-shared Key (WPA-PSK). With WPA key management, clients and the authentication server authenticate to each other by using an EAP authentication method, and the client and the server generate a pairwise master key (PMK). The server generates the PMK dynmically and passes it to the access point. However, with WPA-PSK key management, you configure a pre-shared key on both the client and the access point. The pre-shared key is used as the PMK.

In previous releases, you could only configure WPA-PSK though the Windows CE wireless configuration utility. In release 2.72, you can configure WPA-PSK from the ACU. You can now select "WPA-PSK" in the "Network Security Type" field and then enter the WPA-PSK pass phrase in the "User Password" field.


Note WPA-PSK functionality only applies to CE 4.x. Software releases for CE 3 and Pocket PC 2002 do not support this functionality.


Installing or Upgrading to a New Client Utility and Driver Release

This section describes how to install or upgrade to client utility and driver release 2.72 for
Windows CE.

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 releases. Follow these steps to uninstall your client adapter's current driver and client utilities.


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

Step 2 Tap Start > Settings > System tab > Remove Programs (on PPC devices) or Start > Settings > Control Panel > Remove Programs (on HPC and Windows CE .NET devices).

Step 3 Tap Cisco Wireless LAN Adapter.

Step 4 Tap the Remove button.

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

Step 6 Tap 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 below for instructions on loading the new driver and client utilities.


Loading a New Driver and Client Utilities

Follow these steps to install client utility and driver release 2.72 for your client adapter.


Step 1 Connect your Windows CE device to a laptop or PC running Microsoft ActiveSync. This is typically done using a serial or USB cable.

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 release of ActiveSync.


Step 2 Perform one of the following:

If you want to establish a partnership that enables you to synchronize files between the laptop or PC and the Windows CE device, choose 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," choose No and click Next. The screen indicates that you are connected as a guest.

Step 3 Use your laptop or PC's web browser to access the following URL:

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

Step 4 Click Option #2: Aironet Wireless Software Display Tables.


Note You can download software from the Software Selector tool instead of the display tables. To do so, click Option #1: Aironet Wireless Software Selector, follow the instructions on the screen, and go to Step 9.


Step 5 Click Cisco Aironet Wireless LAN Client Adapters.

Step 6 Find the section for Windows CE client adapter drivers and utilities.

Step 7 Click the link for Windows CE 3.0 or Windows CE .NET, depending on your device's operating system.

Step 8 Click the WinCE-PCMCIA-LMC-v272.exe file.

Step 9 Complete the encryption authorization form; then read and accept the terms and conditions of the Software License Agreement.

Step 10 Click the WinCE-PCMCIA-LMC-v272.exe file to download it.

Step 11 Save the file to the hard drive of your laptop or PC.

Step 12 Find the file using Windows Explorer, double-click it, and extract its files to a folder.


Note Make sure you keep all of the extracted files together in one folder. Moving them to different locations may prevent the software from operating correctly.


Step 13 Double-click the ceInstall.exe file.

Step 14 If you are using a PPC 2002 device, the Install 802.1X Support screen appears. If you are planning to use EAP-TLS or PEAP authentication, click Yes. Otherwise, click No.


Note If you choose Yes, the PPC 2002 802.1X backport, which provides support for 802.1X security, is installed. The backport then becomes part of the base Windows CE operating system and cannot be uninstalled.


Step 15 If you are using a PPC 2002, PPC 2003, or Windows CE .NET 4.2 device, the Cisco PEAP screen appears. If you are planning to use Cisco PEAP authentication, make sure the Install Cisco PEAP Support check box is checked and click Next. Otherwise, uncheck the Install Cisco PEAP Support check box and click Next.


Note If you install the Cisco PEAP supplicant and later want to use the Microsoft PEAP supplicant, you must default your Windows CE device and reinstall the client adapter software.


Step 16 If you installed the 802.1X backport on a PPC 2002 device, a message appears indicating that you must reset your device when the installation is complete. Click OK.

Step 17 If you are not using a PPC 2002 device, the Cisco Aironet Wireless LAN Adapter Setup screen appears. Click Next to start the Windows CE Application Manager (CeAppMgr), which is installed with ActiveSync. CeAppMgr interrogates the Windows CE device to determine its platform type.


Note If a Windows CE device is not connected to the laptop or PC (as instructed in Step 1), click Exit to quit the setup program and connect a Windows CE device or click Next to continue the installation. If you choose Exit, click OK to shut down CeAppMgr and start again beginning with Step 1. If you choose 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.


Step 18 When the Installing Applications 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\Start Menu\Programs\Cisco on PPC devices and \Windows\Programs\Cisco on HPC and Windows CE .NET devices.

A message and a progress bar appear indicating that the client adapter (and 802.1X backport if you are using a PPC 2002 device) is being installed.

The driver and help files are copied to the \Windows directory, and the client utilities are installed in the \Windows\Start Menu\Programs\Cisco directory on PPC devices or the \Windows\Programs\Cisco directory on HPC and Windows CE .NET devices. Shortcuts to ACU and WLM are automatically added to the desktop on HPC and Windows CE .NET devices.

Step 19 When the installation process is complete on the laptop or PC, a message appears asking you to view 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 20 Complete any required steps on the Windows CE device.

Step 21 Disconnect the Windows CE device.

Step 22 If you are using a PPC 2002 device and you installed the 802.1X backport, reset your Windows CE device now. (You should have been notified earlier that a reset would be required after installation.)

Step 23 Insert the client adapter 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 24 The Cisco Wireless LAN Adapter Settings dialog box appears. If the dialog box does not appear, perform one of the following:

Tap Start > Settings > the Connections tab > Connections > Advanced > Network Card > Cisco Wireless LAN Adapter on PPC 2003 devices.

Tap Start > Settings > the Connections tab > Network Adapters > Cisco Wireless LAN Adapter > Properties on PPC 2002 devices.

Tap Start > Settings > Control Panel > Network > the Adapters tab > Cisco Wireless LAN Adapter > Properties on HPC devices.

Tap Start > Settings > Network and Dial-up Connections > the Cisco Wireless LAN Client Adapter icon on Windows CE .NET devices.

Step 25 Perform one of the following:

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

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

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. Choose 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. Tap OK.

The driver and client utility installation is complete. To verify that you have properly installed the driver and client utilities, check the client adapter's LEDs. If the installation was successful, the client adapter's green LED blinks.


Note Refer to the Cisco Aironet 350 Series Wireless LAN Client Adapters Installation and Configuration Guide for Windows CE (part number OL-1375-05) for information on configuring your client adapter.



Caveats

This section describes resolved and open caveats for client utility and driver release 2.72 for
Windows CE.

Resolved Caveats

CSCsc87195—Throughput on PSC handheld LM350 greatly reduced when run with Symbol MC50

When Chariot upstream Filesndl.scr with PSC scanner and Symbol MC50 are run at the same time, the throughput on the PSC scanner is approximately one-third of the throughput on the Symbol device. This condition occurs when WPA-PSK is used. Running PSC by itself does not have a low throughput.

CSCsc99838—ACU WEP utility does not allow a single key in index other than in index 1

If you attempt to put a single WEP key in an index other than index 1, the ACU requests a WEP key. However, if you set the same key in index 1 but set the transmit key to another key, the ACU does not request a WEP key and the client associates correctly.

CSCsd12752—Windows CE.Net 4.2 PSC Falcon 4423 scanner with Cisco Embedded Mini-PCI card does not renew DHCP-generated IP address after controller disassociates and deauthenticates client

The controller disassociates and deauthenticates the client and deletes its context, but the client reassociates before its 10-second disconnect timer expires and notifies the Windows CE stack. The client already has an IP address, but the controller creates a new context and is not aware that the client has an IP address.

Open Caveats

The following caveat is not resolved in client utility and driver release 2.72 for Windows CE.

CSCsc15223—Windows CE device with ACU 2.70 does not reconnect if external profile is used.

A 350 LMC wireless client is installed on a Symbol PDT8100 that is running Windows CE 4.20.0. The ACU is installed on the device. In the ACU, the "External Setting" is configured as "Select Active Profile" so that EAP-TLS can be configured for the Microsoft supplicant (an external profile). The Symbol PDT8100 intially associates to the AP1200. When the device goes out of radio coverage range but later comes within range, the device does not automatically associate to the access point.

Workaround: Manually reconnect the SSID, or restart the device that is running Windows CE.
