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 WLAN in your vicinity. For more
information about the wireless switch, see "wireless switch" on page 26.
To scan for WiFi WLAN, 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 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.
NOTE: The Dell Wi-Fi Catcher Network Locator light appears only when the
computer is turned off and wireless networking is activated in the system setup
program. While working in Microsoft Windows operating systems, the light is
designed not to appear.
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 taskbar and
select Help.

Firewall
Windows Firewall provides basic protection from unauthorized access to your
computer while it is connected to the Internet. Windows Firewall is
automatically enabled when you run the Network Setup Wizard.
When Windows 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: Enabling Windows Firewall does not reduce the need for virus-checking
software.
For more information, click Start→ Control Panel→ Security→ Windows
Firewall, or access the Help and Support Center (click Start→ Help and
Support).
