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.
