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 benecessary 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 (draft). • 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/draft-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. Deactivating the WLAN Device Disconnecting the WLAN device may bedesired 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 Wireless 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 of the radio; it continues to transmit and receive even though it's not connected.). BEFORE USING THE WIRELESS LAN DEVICE, YOU MUST FIRST INSTALL CLICKME! TO ENSURE THAT THE CORRECT SOFTWARE FOR YOUR DEVICE IS INSTALLED. SEE SEE "INSTALLING CLICK ME!"
