Monitoring the Status of Wireless Network Connections Through Dell™ QuickSet

The wireless activity indicator provides an easy way to monitor the status of your computer’s wireless devices. Right-click the Dell QuickSet icon in your taskbar to select or deselect Wireless Activity Indicator Off to turn the wireless activity indicator on or off.

The wireless activity indicator indicates whether your computer’s wireless devices are enabled or disabled. When you turn the wireless networking function on or off, the wireless activity indicator changes to display the status.

For more information about the wireless activity indicator, see the Dell QuickSet Help file. For information about QuickSet and how to access the Dell QuickSet Help file, see "Dell™ QuickSet Features" on page 131.

Mobile Broadband or Wireless Wide Area Network (WWAN)

Much like a WLAN, a Mobile Broadband network (also known as a WWAN) is a series of interconnected computers that communicate with each other through wireless technology. However, a Mobile Broadband network uses cellular technology and therefore provides Internet access in the same varied locations from which cellular telephone service is available. Your computer can maintain the Mobile Broadband network connection regardless of its physical location, as long as the computer remains in the service area of your cellular service provider.

What You Need to Establish a Mobile Broadband Network Connection

NOTE: Depending on your computer, you can use either a Mobile Broadband ExpressCard or Mini-Card, but not both, to establish a Mobile Broadband network connection.

To set up a Mobile Broadband network connection, you need:

•A Mobile Broadband ExpressCard or Mini-Card (depending on your computer’s configuration) For instructions on using ExpressCards, see "Using ExpressCards" on page 65.

•The Dell Mobile Broadband Card Utility (already installed on your computer if you purchased the card when you purchased your computer, or on the CD that accompanied your card if purchased separately from your computer)

If the utility is corrupted or deleted from your computer, see the Dell Mobile Broadband Card Utility user’s guide for instructions. The user’s guide is available through the Windows Help and Support Center (or on the CD that accompanied your card if you purchased it separately from your computer). To access the Help and Support Center, see "Windows Help and Support Center" on page 13.

Connecting to a Mobile Broadband Network
