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.

Wireless Network Considerations

•The WLAN device supports IEEE802.11b, IEEE802.11g, and IEEE802.11n.

•The WLAN device operates in the 2.4 GHz ISM band.

•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.

•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.

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 deactivated by using the [Fn]+[F5] key combination 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.).

Disconnecting using the function keys

To toggle the wireless devices on and off, press the [Fn} key while clicking the [F5] key.

Disconnecting Using the Icon in the Taskbar

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.

1Right-click the WLAN icon in the taskbar at the bottom right of your screen.

2Choose Disconnect from a network.
