Wireless LAN User’s Guide

■

The WLAN device operates in the 2.4 GHz ISM band

and the 5 GHz lower, middle, and upper UNII bands.

■

Microwave ovens may interfere with the operation of

WLAN devices since they operate in the same 2.4 GHz

frequency range as IEEE802.11b/g devices. Interfer-

ence by microwaves does not occur with IEEE802.11a

radio which operates in the 5 GHz RF band.

■

Wireless devices that transmit in the 2.4 GHz fre-

quency range may interfere with the operation of

WLAN devices in IEEE802.11b/g modes. Symptoms of

interference include reduced throughput, intermittent

disconnects, and large amounts of frame errors. It is

recommended that these interfering devices be pow-

ered off to ensure the proper operation of the WLAN.

DEACTIVATING THE WLAN DEVICE

Deactivation of the WLAN device may be desired in

certain circumstances (to extend battery life) or where

certain environments require it (i.e. hospitals, clinics,

airplanes, etc.). Fujitsu mobile computers employ two

methods with which to deactivate the WLAN device,

1) the Wireless On/Off Switch, and, 2) in Windows using

the Intel PROSet for Wireless utility.

Deactivation using the Wireless On/Off Switch

The WLAN device can be deactivated quickly and effi-

ciently by toggling the Wireless On/Off Switch to the Off

position. The switch is located on the left side of the

system. (Figure A-3)

The switch has no effect on non-Wireless LAN models.

Deactivation using Intel PROSet for Wireless Utility

The WLAN device can also be deactivated in Windows

using the Intel PROSet for Wireless utility. The proce-

dure to accomplish this:

1. Click [Start]-> [All Programs].

2. Select Intel ProSet Wireless, then click on Intel

ProSet Wireless from the menu that appears. The

Intel ProSet Wireless utility will be displayed.

3. At the bottom left corner of the window, select

Wireless Off from the dropdown list.

ACTIVATING THE WLAN DEVICE

Activation of the WLAN device can be accomplished

using the same methods as the deactivation process.
