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 WiFi wireless local area networks (LAN) in your
vicinity.
NOTE: For more information about the wireless switch, see
To scan for WiFi wireless LAN, slide and hold the 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, in hibernate mode, or in standby mode, as long as the switch is configured through 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 QuickSet, see the Dell QuickSet Help. To access the Help file,
right-click the icon in the taskbar.
Internet Connection Firewall
The Internet Connection Firewall provides basic protection from unauthorized access to the computer while the computer is connected to the Internet. The
firewall is automatically enabled when you run the Network Setup Wizard. When the firewall is enabled for a network connection, the firewall icon appears
with a red background in the Network Connections section of the Control Panel.
Note that enabling the Internet Connection Firewall does not reduce the need for virus-checking software.
