How to Handle This Device

The WLAN device is an optional device that may come pre-installed in your mobile computer. Under normal circumstances, it should not be necessary for you to remove or re-install it. The Operating System that your mobile computer comes with has been pre-configured to support the WLAN device.

WIRELESS NETWORK CONSIDERATIONS

■Intel Wireless WiFi Link 4965AGN device supports IEEE802.11a, IEEE802.11b, IEEE802.11g, and IEEE802.11n.

■The Atheros SuperAG WLAN device supports IEEE802.11a, IEEE802.11b, and IEEE802.11g.

■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/n devices. 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 range may interfere with operation of WLAN devices in IEEE802.11b/g/n modes. Symptoms of interference include reduced throughput, intermittent discon- nects, and many frame errors. It is HIGHLY recom- mended that these interfering devices be powered off to ensure 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:

■Using the Wireless On/Off Switch, or,

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

Before using the wireless LAN device, you must first install ClickMe! to ensure that the correct software for your device is installed.

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.
