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.

WIRELESS NETWORK CONSIDERATIONS

The WLAN devices support IEEE802.11a+b/g.

The devices operate in the 2.4GHz ISM band the 5 GHz lower and middle UNII bands.

Microwave ovens will interfere with the operation of WLAN device as microwave ovens operate in the same 2.4GHz frequency range that IEEE802.11b/g devices operate in. Interference 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. Interference symptoms include reduced throughput, intermittent disconnects, and large amounts of frame errors. It is HIGHLY recommended that interfering devices be powered off to ensure 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:

Using the Wireless On/Off Switch, or,

In Windows Vista, using the WLAN icon in the taskbar.

In Windows XP, using the Intel PROSet Software or Atheros Client Utility software.

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. (Figure A-3)

The wireless On/Off switch has no effect on non-Wire- less LAN models.

Windows Vista: Deactivation using the icon in the taskbar

1.Right-click the WLAN icon in the taskbar at the bottom right of your screen.

2.Choose Disconnect from a network.
