Setting Up and Using Networks
Enabling/Disabling the Wireless Network Card
NOTE:
If you are unable to connect to a wireless network, ensure that you have all
the components for establishing a WLAN (see "What You Need to Establish a WLAN
Connection" on page 89), and then verify that your wireless network card is enabled
by pressing <Fn><F2>.
You can turn your computer’s wireless networking function on and off by
pressing the <Fn><F2> key combination.
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 / Wireless Wide Area
Network (WWAN)
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.
NOTE:
Even if you are able to make a call from your cellular phone in a specific
geographical location, that location may not necessarily be within a cellular-data
coverage zone.
