WIreless LAN User’s Guide

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
