Enabling/Disabling the Dell Mobile Broadband Network Card

NOTE: If you are unable to connect to a Mobile Broadband network, ensure that you have all the components for establishing a Mobile Broadband connection (see What You Need to Establish a Mobile Broadband Network Connection), and then verify that your Mobile Broadband card is enabled by verifying the setting of the wireless switch.

You can turn your Mobile Broadband card on and off using the wireless switch on your computer.

You can turn your computer's wireless devices on and off with the wireless switch on the left side of the computer (see Left Side View).

If the switch is in the "on" position, move the switch to the "off" position to disable the switch and the Mobile Broadband card. If the switch is in the "off" position, move the switch to the "on" position to enable the switch and the Dell Mobile Broadband card. For information about the wireless switch positions, see wireless switch.

To monitor the status of your wireless device, see Monitoring the Status of Wireless Network Connections Through Dell™ QuickSet.

Managing Your Network Settings Through the Dell QuickSet Location Profiler

The 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.

For information about Dell QuickSet, see Dell™ QuickSet.

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 wireless switch.

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.

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.
