How to Handle This Device
The WLAN device is an opt ional 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.
• Integrated Intel Centrino wireless LAN devices support IEEE802.11a,
IEEE802.11b, IEEE802.11g, and IEEE802.11n.
• The WLAN device operat es in the 2.4 GHz ISM band and the 5 GHz
lower, middle, and upper UNII bands.
• Microwave ovens ma y 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 disconnects, and many frame errors. It is HIGHLY recommended that these
interfering devices be powered off to ensure proper operation of the WLAN device.
