1 Integrated wireless devices
Wireless technology makes a computer mobile by transferring data across radio waves instead of wires.
Your computer may be equipped with one or more of the following integrated wireless devices:
●Bluetooth® device—Creates a personal area network (PAN) to connect to other Bluetooth-enabled
devices such as computers, phones, printers, headsets, speakers, and cameras. In a PAN, each
device communicates directly with other devices, and devices must be relatively close together—
typically within 33 feet of each other.
●Wireless local area network (WLAN) device—Connects the computer to wireless local area
networks (commonly referred to as wireless networks, wireless LANs, or WLANs) in corporate
offices, your home, and public places such as airports, restaurants, coffee shops, hotels, and
universities. In a WLAN, each mobile wireless device communicates with a wireless access point,
which can be several hundred feet away.
●Wireless wide area network (WWAN) device—Provides access to information anytime and
anywhere you have cellular (data) coverage. In a WWAN, each mobile device communicates to a
public carrier’s base station. Public carriers install networks of base stations (similar to cell phone
towers) throughout large geographic areas, effectively providing coverage across entire states,
regions, or even countries.

2 Wireless controls
You can control the wireless devices in your computer using one of three methods:
●Wireless button or wireless switch (referred to as wireless button)
●Wireless Assistant software (select models only)
●Operating system controls (setup utility)

Wireless button
The computer has a wireless button, one or more wireless devices, and one or two wireless lights,
depending on model. All of the wireless devices on your computer are enabled at the factory, so the
wireless light is on (blue) when you turn on the computer.
The wireless light indicates the overall power state of your wireless devices, not the status of individual
devices. If the wireless light is blue, at least one wireless device is turned on. If the wireless light is turned
off, all wireless devices are turned off.
NOTE On some models, the wireless light is amber when all wireless devices are turned off.
Because the wireless devices are enabled at the factory, you can use the wireless button to turn on or
turn off the wireless devices simultaneously. Individual wireless devices can be controlled through
Wireless Assistant software (select models only) or through the setup utility.
NOTE If the wireless devices are disabled , the wireless button will not work until you reenable
your devices.

Wireless Assistant software (select models only)
When a wireless device is enabled, it can be turned on or off using the Wireless Assistant software.
Once a wireless device is disabled, however, it must be enabled before it can be turned on or off using
Wireless Assistant.
NOTE Enabling or turning on a wireless device does not automatically connect the computer
to a network or a Bluetooth-enabled device.
To view the state of the wireless devices, click the Wireless Assistant icon in the Windows Mobility
Center.
For more information about Wireless Assistant:
1. Open Wireless Assistant by clicking the icon in the Windows Mobility Center.
2. Click the Help button.
NOTE You cannot use Wireless Assistant to control the wireless devices if they have been
disabled in the setup utility. For more information, refer to the Wireless Assistant online Help.
Operating system controls
Some operating systems and client managers also offer a way to manage integrated wireless devices
and the wireless connection. For more information, refer to the documentation for your operating system
or client manager.

3 Bluetooth wireless devices (select
models only)
A Bluetooth device provides short-range wireless communications that replace the physical cable
connections that traditionally link electronic devices such as
●Network access points.
●Computers (desktop, notebook, PDA).
●Phones (cellular, cordless, smart phone).
●Imaging devices (printer, camera).
●Audio devices (headset, speakers).
Bluetooth devices provide peer-to-peer capability that allows you to set up a PAN of Bluetooth devices.
For information on configuring and using Bluetooth devices, refer to the Bluetooth online Help.

4 WLAN devices (select models only)
With a WLAN device, you can access a wireless local area network, which is composed of other
computers and accessories linked by a wireless router or a wireless access point.
NOTE The terms wireless access point and wireless router are often used interchangeably.
●A large-scale WLAN, such as a corporate or public WLAN, typically uses wireless access points
that can accommodate a large number of computers and accessories and can separate critical
network functions.
●A home or small office WLAN typically uses a wireless router, which allows several wireless and
wired computers to share an Internet connection, a printer, and files without requiring additional
pieces of hardware or software.
NOTE To use the WLAN device in your computer, you must connect to a WLAN infrastructure
(provided through a service provider or a public or corporate network).
Computers with WLAN devices may support one or more of four IEEE physical layer industry standards:
●802.11b, the first popular standard, supports data rates of up to 11 Mbps and operates at a
frequency of 2.4 GHz.
●802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g
WLAN device is backward compatible with 802.11b devices, so they can operate on the same
network.
●802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz.
NOTE 802.11a is not compatible with 802.11b and 802.11g.
●802.11n supports data rates of up to 270 Mbps and may operate at 2.4 GHz or 5 GHz, making it
backward compatible with 802.11a, b, and g.
