For specific information about the wireless configuration utility installed on your computer, see your wireless network documentation in the Windows Help and
Support Center (click Start® Help and Support).
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.
Monitoring the Status of the Wireless Network Card Through Dell QuickSet
The wireless activity indicator provides you with an easy way to monitor the status of your computer's wireless devices. To turn the wireless activity indicator
on or off, click the QuickSet icon in the taskbar and select Hotkey Popups. If Wireless Activity Indicator Off is not checked, the indicator is on. If Wireless
Activity Indicator Off is checked, the indicator is off.
The wireless activity indicator displays whether your computer's integrated 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 Dell QuickSet wireless activity indicator, right-click the QuickSet icon in the taskbar and select Help.
Mobile Broadband (or Wireless Wide Area Network)
A Mobile Broadband network, also known as a Wireless Wide Area Network (WWAN), is a high-speed digital cellular network that provides Internet access
over a much wider geographical area than a WLAN, which typically covers only from 100 to 1000 feet. Your computer can maintain Mobile Broadband network
access as long as the computer is within a cellular-data coverage zone. Contact your service provider for coverage of a high-speed digital cellular network.
What You Need to Establish a Mobile Broadband Network Connection
To set up a Mobile Broadband network connection, you need:
l A Mini-Card
l An activated Subscriber Identity Module (SIM) for your service provider
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
media 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 (click Start® Help and Support) or on the media that accompanied your card if you purchased
it separately from your computer.
Checking Your Dell Mobile Broadband Card
Depending on what you selected when you purchased your computer, the computer has a variety of configurations. To determine your computer configuration,
