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.
15
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.
●
Bluetooth device—Creates a personal area network (PAN) to connect to other Bluetoothenabled devices such as computers and phones. In a PAN, the computer communicates directly
with other devices. A devices must be relatively close to the computer—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.
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)
●
HP Connection Manager software
●
Operating system controls
Using the wireless button
Your computer has a wireless button, one or more wireless devices, and one wireless light. 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 amber, 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 HP
Connection Manager.
Using HP Connection Manager
HP Connection Manager provides a central location for managing your wireless devices. HP
Connection Manager allows you to manage the following devices:
● Wireless local area network (WLAN)/Wi-Fi
● Bluetooth
HP Connection Manager provides information and notifications on connection status and power
status. Status information and notifications are provided in the notification area, at the far right of the
taskbar.
16 Chapter 3 Connecting to a network
To open HP Connection Manager, select Start > All Programs > HP Help and Support > HP
Connection Manager.
For more details about using HP Connection Manager, see the HP Connection Manager software
Help.
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, select Start > 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 computer 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.
Connecting to a wireless network 17
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

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 in 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.
Wireless encryption uses security settings to encrypt and decrypt data that is transmitted over
the network. For more information, see Help and Support.

Connecting to a WLAN
To connect to the WLAN, follow these steps:
1. Be sure that the WLAN device is on. If the device is on, the wireless light is on (white). If the
wireless light is amber, press the wireless button.
2. Click the network status icon in the notification area, at the far right of the taskbar.
3. Select your WLAN from the list.
4. Click Connect.
If the WLAN is a security-enabled WLAN, you are prompted to enter a security code. Type the
code, and then click OK to complete the connection.
NOTE: If no WLANs are listed, you may be out of range of a wireless router or access point.
NOTE: If you do not see the WLAN you want to connect to, click Open Network and Sharing
Center, and then click Set up a new connection or network. A list of options is displayed,
allowing you to manually search for and connect to a network or to create a new network
connection.
After the connection is made, place the mouse pointer over the network status icon in the notification
area, at the far right of the taskbar, to verify the name and status of the connection.
NOTE: The functional range (how far your wireless signals travel) depends on WLAN
implementation, router manufacturer, and interference from other electronic devices or structural
barriers such as walls and floors.
Using 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 the following:
●
Computers (desktop, notebook, PDA)
●
Phones (cellular, cordless, smart phone)
●
Imaging devices (printer, camera)
●
Audio devices (headset, speakers)
●
Mouse
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information about configuring and using Bluetooth devices, see the
Bluetooth software Help.
Connecting to a wireless network 19
Connecting to a wired network
Your computer supports a local area network (LAN) wired connection. A LAN connection uses a
network cable and is much faster than a modem, which uses telephone cable. LAN (RJ-45) cables
are sold separately.
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a
modem cable or telephone cable into an RJ-45 jack.
Connecting to a local area network (LAN)
Use a LAN connection if you want to connect the computer directly to a router in your home (instead
of working wirelessly), or if you want to connect to an existing network at your office.
Connecting to a LAN requires an 8-pin, RJ-45 network cable.
To connect the network cable, follow these steps:
1. Plug the network cable into the network jack (1) on the computer.
2. Plug the other end of the network cable into a network wall jack (2) or router.
NOTE: If the network cable contains noise suppression circuitry (3), which prevents
interference from TV and radio reception, orient the circuitry end of the cable toward the
computer.
