Deactivating/Disconnecting The Wlan Device - Fujitsu LifeBook E8420 User Manual

How to Handle This Device
The WLAN device is an optional 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.
• Intel WiFi Link 5300 device supports IEEE802.11a, IEEE802.11b, IEEE802.11g, and
IEEE802.11n.
• The WLAN device operates in the 2.4 GHz 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
2.4 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.

Deactivating/Disconnecting the WLAN Device

Disconnecting 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.). The WLAN device can be
deativated by using the Wireless Device On/Off Switch, and it can be disconnected in Windows using the
WLAN icon in the system tray (Note that disconnecting via the icon in the system tray does not turn off
the radio; it continues to transmit and receive even though it's not connected.).
