Safety warning notice
WARNING! To reduce the possibility of heat-related injuries or of overheating the computer, do not
place the computer directly on your lap or obstruct the computer air vents. Use the computer only on
a hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft
surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to
come into contact with the skin or a soft surface, such as pillows or rugs or clothing, during operation.
The computer and the AC adapter comply with the user-accessible surface temperature limits defined
by the International Standard for Safety of Information Technology Equipment (IEC 60950).

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
Help and Support. From the Start screen, type h, and then select 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
●
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.
Connecting to a wireless network 15
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:
1. From the Start screen, type n, and then select Settings.
2. Type network and sharing in the search box, and then select Network and Sharing
Center.
For more information, from the Start screen, type h, and then select Help and Support.
Using a WLAN
With a WLAN device, you can access a wireless local area network (WLAN), which is composed of
other computers and accessories that are linked by a wireless router or a wireless access point.
NOTE: The terms wireless router and wireless access point 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.
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).
Using an Internet service provider
When you are setting up Internet access in your home, you must establish an account with an
Internet service provider (ISP). To purchase Internet service and a modem, contact a local ISP. The
ISP will help set up the modem, install a network cable to connect your wireless router to the modem,
and test the Internet service.
NOTE: Your ISP will give you a user ID and a password to use for Internet access. Record this
information and store it in a safe place.
16 Chapter 3 Connecting to a network
Setting up a WLAN
To set up a WLAN and connect to the Internet, you need the following equipment:
A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from
●
an Internet service provider
A wireless router (2) (purchased separately)
●
A wireless computer (3)
●
NOTE: Some modems have a built-in wireless router. Check with your ISP to determine what type
of modem you have.
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
As your network grows, additional wireless and wired computers can be connected to the network to
access the Internet.
For help in setting up your WLAN, see the information provided by your router manufacturer or your
ISP.
Configuring a wireless router
For help in setting up a WLAN, see the information provided by your router manufacturer or your ISP.
NOTE: It is recommended that you initially connect your new wireless computer to the router by
using the network cable provided with the router. When the computer successfully connects to the
Internet, disconnect the cable, and access the Internet through your wireless network.
Protecting your WLAN
When you set up a WLAN or access an existing WLAN, always enable security features to protect
your network from unauthorized access. WLANs in public areas (hotspots) like coffee shops and
airports may not provide any security. If you are concerned about the security of your computer when
connected to a hotspot, limit your network activities to email that is not confidential and basic Internet
surfing.
Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotected
signals. Take the following precautions to protect your WLAN:
Use a firewall.
●
A firewall checks both data and requests for data that are sent to your network, and discards any
suspicious items. Firewalls are available in both software and hardware. Some networks use a
combination of both types.
● Use wireless encryption.
