3 Connecting 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 HP
Support Assistant. To access HP Support Assistant on the Start screen, select the HP Support
Assistant app.
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
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.
