Chapter 3. Troubleshooting

Intel® PRO/Wireless 2011B LAN USB Device is similar to a wired network adapter except that the connection is wireless. The troubleshooting techniques that apply to a wired network adapter also apply to this wireless device.

To see if the wireless device is working, note the color of the device icon on the right side of the Windows taskbar:

Green indicates that the device is communicating. Double-click the icon for more status information. For more information, see Chapter 2.

The light on the front of the device indicates the following:

Off: no power

Blink: looking for association

On: associated or in Ad Hoc mode

Unable to communicate with an access point or other wireless computers

For the wireless device to communicate with an access point or otherwireless computers::

The Network Name (SSID) of all wireless devices must match.

If the WEP encryption option is enabled, all wireless devices must use the same encryption level and key.

The preamble settings of the device must be the same as the settings for other wireless devices. If the access point or other devices use long preamble headers, your device must also use long preamble headers. To check or change the preamble settings:

1.Double-click My Computer, and then double-click Control Panel.

2.Double-click Network.

Windows 2000: Right-click the Local Area Connection for the Intel(R) PRO/Wireless 2011B LAN USB Device and click Properties.

Windows ME, 98, and 95: Select Intel(R) PRO/Wireless 2011B LAN USB Device and click Properties.

3.Click the Advanced tab and select Preamble Mode.

Degraded performance detected

Place the Intel® PRO/Wireless 2011B LAN USB Device in an open area and as high as possible. Metal objects and fluorescent lights can adversely affect performance.

Windows 98 Troubleshooting Tips

Windows 98 does not recognize the Intel® PRO/Wireless 2011B LAN USB Device when installed.

Verify the computer has a Plug and Play BIOS.

The driver fails to load.

A resource conflict could exist. Use the Device Manager to resolve resource conflicts. Select the System applet from the Control Panel. Select the Device Manager tab.

Network drive mappings disappear when the laptop suspends or the device is removed then reinserted. Windows 98 does not restore network drive mappings under these conditions.

Log out and log in again, or restart the computer to restore the connections.
