3. Under Device Guides, select the documentation for your wireless network card.

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.

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 Using Cards.

•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.

Checking Your Mobile Broadband Network Card

For information, see Checking Your Wireless Network Card.

Connecting to a Mobile Broadband Network

NOTE: These instructions only apply to Mobile Broadband ExpressCards or Mini-Cards. They do not apply to internal cards with Bluetooth® wireless technology or WLAN Mini-Cards.

NOTE: Before you connect to the Internet, you must activate Mobile Broadband service through your cellular service provider. For instructions and for additional information about using the Dell Mobile Broadband Card Utility, see the user's guide available through the Windows Help and Support Center. To access the Help and Support Center, see Windows Help and Support Center. The user's guide is also available on the Dell Support website at support.dell.com and on the CD included with your Mobile Broadband card if you purchased the card separately from your computer.

Use the Dell Mobile Broadband Card Utility to establish and manage a Mobile Broadband network connection to the Internet:
