Managing Your Network Settings Through the Dell QuickSet Location Profiler

The Dell QuickSet Location Profiler helps you manage network settings that correspond to your computer’s physical location. It includes two categories of profile settings:

•Location Profile Settings

•General Mobility Settings

You can use Location Profile Settings to create profiles for accessing the Internet with your computer in your office, home, or other public places with Internet services. General Mobility Settings allows you to change the way network connections are handled. The profiles consist of different network settings and equipment that you need when using your computer in different locations.

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 20.

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 or sleep mode, as long as the switch is configured through Dell QuickSet or the BIOS (system setup program) 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.

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 taskbar and select Help.

Microsoft® Windows® 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.
