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 (see "wireless
switch" on page 27) 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.
The Wi-Fi Catcher Network Locator is enabled and configured for use when
your computer is shipped to you. For more information on the Wi-Fi Catcher
Network Locator and to enable or disable the feature through Dell QuickSet,
right-click the QuickSet icon in the notification area, and then select Help.
