How to Handle This Device
The W LAN 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 o r re-install it. The Operating
System that your mobile compute r comes with has been pre-configured to support the WL A N device.
• 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 W LAN
devices in IEEE802.11b/g/n modes. Symptoms of interference include reduced throughput,
intermittent disconnects, and many frame errors. It is HIGHLY recommende d that these
interfering devices be powered off to ensure proper operation of the WLAN device.
Deactivating/Disc
onnecting the WLAN Device
Disconnecting the WLAN device may be desired in certain c ircumstances (to extend battery
life) or where certain environments require it (i.e. hospitals, clinics, airplanes, etc.). The
WLAN device can be disconnected in W indows using the WLA N icon in the system tray
(Note that disconnecting via the icon in the system tray does not turn off the radio; it
continues to transmit and receive even though it’s not connected.)
