Dell Wi-Fi Catcher™ Network Locator
The wireless switch on your Dell computer uses the Dell Wi-Fi Catcher
Network Locator to scan specifically for wireless networks in your vicinity.
To scan for a wireless network, slide and hold the wireless switch in the
momentary position for a few seconds. The Wi-Fi Catcher Network Locator
functions regardless of whether your computer is turned on or off, or in Sleep
state, as long as the switch is configured through Dell QuickSet or the BIOS
(system setup program) to control WiFi network connections.
Because the Wi-Fi Catcher Network Locator is disabled and not configured
for use when your computer is shipped to you, you must first use Dell
QuickSet to enable and configure the switch to control WiFi network
connections. For more information on the Wi-Fi Catcher Network Locator
and to enable the feature through Dell QuickSet, right-click the QuickSet
icon in the notification area, and then select Help.
