Dell Latitude D620 - Manual (Page 102)

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 Wi-Fi 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.
For more information, see the Help and Support Center for the Microsoft® Windows® XP operating system. To access the Help and Support Center, see
Windows Help and Support Center .
