							3Connecting to a network
Your computer can travel with you wherever you go. But even at home, you can explore the globe and access 
information from millions of websites using your computer and a wired or wireless network connection. This 
chapter will help you get connected to that world.
Connecting to a wireless network
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, the 
mobile wireless device in your computer communicates with a wireless router or a wireless access 
point.
●HP Mobile Broadband Module (select models only)—A wireless wide area network (WWAN) device that 
gives you wireless connectivity over a much larger area. Mobile network operators install 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.
For more information about wireless technology, see the information and website links provided in Help and  Support. To access Help and Support, select 
Start > Help and Support.
Using the wireless controls
You can control the wireless devices in your computer using these features:
●Wireless button, wireless switch, or wireless key (referred to in this chapter as the wireless button)
●Operating system controls
Turning wireless devices on or off
You can use the wireless button or HP Connection Manager (select models only) to turn on and turn off 
wireless devices.
NOTE:A computer may have a wireless button, a wireless switch, or a wireless key on the keyboard. The 
term wireless button is used throughout this guide to refer to all types of wireless controls.
To turn off wireless devices using HP Connection Manager:
▲Right-click the HP Connection Manager icon in the notification area, at the far right of the taskbar, and 
then click the power button next to the desired device.
-or-
Select Start > All Programs > Productivity and Tools > HP Connection Manager, and then click the 
power button next to the desired device.
Connecting to a wireless network17  
						

							Using HP Connection Manager (select models only)
HP Connection Manager provides a central location for managing your wireless devices, an interface for 
connecting to the Internet using HP Mobile Broadband, and an interface for sending and receiving SMS (text) 
messages. HP Connection Manager allows you to manage the following devices:
●Wireless local area network (WLAN)/Wi-Fi
●Wireless wide area network (WWAN)/HP Mobile Broadband
●Bluetooth
HP Connection Manager provides information and notifications on connection status, power status, SIM 
details, and SMS messages. Status information and notifications are provided in the notification area, at the 
far right of the taskbar.
To open HP Connection Manager:
▲Click the HP Connection Manager icon in the taskbar.
-or-
Select Start > All Programs > Productivity and Tools > HP Connection Manager.
For more information, see the HP Connection Manager software Help.
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 (white) 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 white, 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.
Using operating system controls
The Network and Sharing Center allows you to set up a connection or network, connect to a network, manage 
wireless networks, and diagnose and repair network problems.
To use operating system controls:
▲Select Start > Control Panel > Network and Internet > Network and Sharing Center.
For more information, access Help and Support by selecting Start > Help and Support.
Sharing data and drives and accessing software
When your computer is part of a network, you are not limited to using only the information that is stored in 
your computer. Network computers can exchange software and data with each other.
NOTE:When a disc like a DVD movie or game is copy-protected, it cannot be shared.
To share on the same network:
