Completing the Connection to the WLAN
When you turn on your computer and a network (for which your computer is not configured) is detected in the area, a pop-up appears near the network icon
in the notification area (in the lower-right corner of the Windows desktop).
Follow the instructions provided in any utility prompts that appear on your screen.
Once you have configured your computer for the wireless network that you selected, another pop-up notifies you that your computer is connected to that
network.
Thereafter, whenever you log on to your computer within the range of the wireless network that you selected, the same pop-up notifies you of the wireless
network connection.
NOTE: If you select a secure network, you must enter a WEP or WPA key when prompted. Network security settings are unique to your network. Dell
cannot provide this information.
NOTE: Your computer can take up to 1 minute to connect to the network.
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.
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.
NOTE: Mobile Broadband cards may not be available in all regions.
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
l
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
l
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).
