How to Handle This Device
The WLAN device comes pre-installed in your mobile
computer. Under normal circumstances, it should not be
necessary for you to remove or re-install it. The Oper-
ating System that your mobile computer comes with has
been pre-configured to support the WLAN device.
■
The Intel PRO/Wireless 3945ABG WLAN device sup-
ports IEEE802.11a, IEEE802.11b and IEEE802.11g.
■
Intel Wireless WiFi Link 4965AGN (4965AGN) device
supports IEEE802.11a, IEEE802.11b, IEEE802.11g,
and IEEE802.11n.
■
The WLAN device operates in the 2.4GHz 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 2.4GHz
frequency range as IEEE802.11b/g/n devices. Interfer-
ence 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 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.
DEACTIVATING THE WLAN DEVICE
Deactivation 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.). To deactivate the WLAN device, use the
Wireless On/Off Switch.
Deactivation using the Wireless On/Off Switch
The WLAN device can be deactivated 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 methods as the deactivation process
■
Using the Wireless On/Off Switch
■
In Windows, by right-clicking the WLAN icon then
clicking “Connect to a network”
