How to Handle This Device
The WLAN device comes pre-installed in your mobile
computer. Under normal circumstances, it should not be
necessary for you to remove or re-install it. The Oper-
ating System that your mobile computer comes with has
been pre-configured to support the WLAN device.
■
The Intel PRO/Wireless 2200BG WLAN device oper-
ates in the 2.4 GHz ISM band.
■
Microwave ovens may interfere with the operation of
the WLAN device as microwave ovens operate in the
same 2.4 GHz frequency range that IEEE802.11b/g
devices operate in.
■
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
HIGHLY recommended that these interfering devices
be powered off to ensure the proper operation of the
WLAN device.
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 switching the Wireless On/Off Switch to the
Off position. The switch is located above the keyboard,
to the left of the Power/Suspend/Resume button.
(Figure 5-3)
The Wireless On/Off switch has no effect on non-Wire-
less 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:
■
Using the Wireless On/Off Switch
■
In Windows using the Intel PROSet for Wireless util-
ity. If using Intel PROSet to activate the device, be sure
to turn the switch on first.
If the WLAN device is turned off using
Intel PROSet, it must be reactivated using
Intel PROSet.
