							3 Wireless and local area network
Using wireless devices
Wireless technology transfers data across radio waves instead of wires. Your computer may be
equipped with one or more of the following wireless devices:
●Wireless local area network (WLAN) device—Connects the computer to wireless local area
networks (commonly referred to as Wi-Fi 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 router or a wireless access
point.
●HP Mobile Broadband Module—A wireless wide area network (WWAN) device that provides
access to information wherever mobile network operator service is available. In a WWAN, each
mobile device communicates to a mobile network operator’s base station. Mobile network operators
install networks of base stations (similar to cell phone towers) throughout large geographic areas,
effectively providing coverage across entire states, regions, or even countries.
●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 10 meters (approximately 33 feet) of each other.
Computers with WLAN devices support one or more of the following IEEE 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 450 Mbps and may operate at 2.4 GHz or 5 GHz, making it
backward compatible with 802.11a, b, and g.

							Using the wireless button
The computer has a wireless button, one or more wireless devices, and one or two wireless lights,
depending on the 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 on. If the wireless light is off, all
wireless devices are off.
NOTE:On some models, the wireless light is amber when all wireless devices are 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).
Using Wireless Assistant software (select models only)
A wireless device can be turned on or off using the Wireless Assistant software. If a wireless device is
disabled in Setup Utility, it must be reenabled in Setup Utility 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 Show hidden icons  icon, the arrow at the left of the
notification area, and position the mouse pointer over the wireless icon.
If the wireless icon is not displayed in the notification area, complete the following steps to change
Wireless Assistant properties:
1.Select Start > Control Panel > Hardware and Sound > Windows Mobility Center.
2.Click the wireless icon in the Wireless Assistant tile, which is located in the bottom row of
Windows
® Mobility Center.
3.Click Properties.
4.Select the check box next to HP Wireless Assistant icon in notification area.
5.Click Apply.
6.Click Close.
For more information, refer to the Wireless Assistant software Help:
1.Open Wireless Assistant by clicking the wireless icon in Windows Mobility Center.

a connection or network, connect to a network, manage wireless networks, and diagnose and repair
network problems.
To access the Network and Sharing Center, select Start > Control Panel > Network and Internet >
Network and Sharing Center.
