WIRELESS NETWORK CONSIDERATIONS

■ The WLAN device supports IEEE802.11a/b/g and
operates in the 2.4GHz ISM band and the 5 GHz UNII
bands.
The maximum range of the WLAN device indoors is
■
typically 80 feet (25 meters). Please note that the max-
imum range you achieve may be shorter or longer than
80 feet, depending on factors such as access point
transmit power, number and density of obstructions,
or external RF interference.
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 2.4GHz 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 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-Wireless LAN models.

Deactivation using Intel PROSet for Wireless Utility
The WLAN device can be deactivated in Windows using
the Intel PROSet for Wireless utility. The procedure 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
