WIRELESS NETWORK CONSIDERATIONS
■
The Atheros WLAN device supports IEEE802.11a/b/g
and operates in the 2.4GHz ISM band and the 5 GHz
UNII bands.
■
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 (disabling) 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.).
Deactivation using the Wireless On/Off Switch
The WLAN device can be disabled quickly and effi-
ciently by sliding the Wireless On/Off Switch to the Off
position (to the left).
(Figure A-3)
The wireless On/Off switch has no effect on non-Wire-
less LAN models.

ACTIVATING THE WLAN DEVICE
Activation of the WLAN device can be accomplished
using the same method as the deactivation process using
the Wireless On/Off Switch.
