Labels

The labels affixed to the computer provide information you may need when you troubleshoot system problems or travel internationally with the computer. The labels are in easily accessible locations.

●

Service label—Provides important information, including the following:

Component

(1) Product name

(2) Serial number

(3) Product part number

(4) Warranty period

(5) Model description (select models only)

Have this information available when you contact support. The service label is affixed inside the battery bay.

Regulatory label—Provides regulatory information about the computer. The regulatory label is

●

affixed inside the battery bay.

Wireless certification label or labels—Provide information about optional wireless devices and

●

the approval markings of some of the countries or regions in which the devices have been approved for use. If your computer model includes one or more wireless devices, one or more certification labels are included with your computer. You may need this information when traveling internationally. Wireless certification labels are affixed inside the battery bay.

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

●

18 Chapter 3 Connecting to a network

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 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.

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.
