# Troubleshooting

Except for the lack of a wired network connection, the Intel® PRO/Wireless 2011B LAN Adapter is just like any mobile network adapter. The troubleshooting techniques that apply to mobile network adapters in general also apply to the Intel PRO/Wireless 2011B LAN Adapter.

For an adapter to communicate with an access point:

- The Network Name (SSID) of the adapter and access point must match.
- If the WEP encryption option is enabled on the access point, the adapter must support this option, and the adapter and access point must use the same encryption keys.

Short RF Preamble Setting must be configured correctly in a multi-vendor LAN. For more information, see the troubleshooting section in the Intel® PRO/Wireless 2011B LAN Access Point User's Guide. To view this guide, click View Other Guides on the left side of this window.

### Windows CE Troubleshooting

The following problem scenarios could be encountered when using the Intel PRO/Wireless 2011B LAN Adapter in a Windows CE environment.

#### The Windows CE Device Does Not Recognize the Adapter

The device may display an Unidentified PC Card Adapter window when the Intel PRO/Wireless 2011B LAN Adapter is inserted into the device.

This probably means the Intel PRO/Wireless 2011B LAN 32-bit Windows CE driver was not loaded or was loaded incorrectly. If this is the case the driver files require reinstallation. For more information, click here.

To verify that the handheld computer recognizes the Intel PRO/Wireless 2011B LAN Adapter:

1. Tap Start, select Settings, and Control Panel.
2. Double-tap the System icon.

- The Expansion Slot in the System section of the System Properties window should list Low_Power_Ethernet.
- This window displays the type of processor the handheld computer uses.

3. If the handheld computer does not recognize the Intel PRO/Wireless 2011B LAN Adapter and does not display an Unidentified PC Card Adapter window, remove and reinsert the adapter.

If the handheld computer has an adapter locking mechanism, verify that it is engaged after the adapter has been re-inserted.

#### An IP Address Is Not Recognized by the Handheld Computer

Remove and reinsert the adapter for changes to the IP address to take effect once the Network program has been run from the Windows CE Control Panel.
