2 Wireless, local area network, and
modem
Using wireless devices
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, each mobile wireless device communicates with a wireless router or a wireless access
point.
Bluetooth® device (select models only)—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.
Computers with WLAN devices support one or more of the following IEEE industry standards:
802.11b, the first popular standard, supports data rates of up to 11 Mbps and operates at a
●
frequency of 2.4 GHz.
802.11g supports data rates of up to 54 Mbps and operates at a frequency of 2.4 GHz. An 802.11g
●
WLAN device is backward compatible with 802.11b devices, so they can operate on the same
network.
802.11a supports data rates of up to 54 Mbps and operates at a frequency of 5 GHz.
●
NOTE: 802.11a is not compatible with 802.11b and 802.11g.
802.11n supports data rates of up to 450 Mbps and may operate at 2.4 GHz or 5 GHz, making it
●
backward compatible with 802.11a, b, and g.
For more information on wireless technology, refer to the information and Web site links provided in
Help and Support.

key (f12) on the computer. Also identifies the HP Wireless Assistant
software on the computer and indicates that one or more of the
wireless devices are on.
Wireless (disconnected) Identifies the HP Wireless Assistant software on the computer and
indicates that all of the wireless devices are off.
Wired network (connected) Indicates that one or more network drivers are installed, and one or

Assistant).
HP Wireless Assistant software
●
Operating system controls
●
Using the wireless action key
The computer has a wireless action key (f12), one or more wireless devices, and a 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 on (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 action key (f12) to
turn on or turn off the wireless devices simultaneously. Individual wireless devices can be controlled
through HP Wireless Assistant.
14 Chapter 2 Wireless, local area network, and modem
Using HP Wireless Assistant
A wireless device can be turned on or off using HP Wireless Assistant. If a wireless device is disabled
in Setup Utility, it must be reenabled in Setup Utility before it can be turned on or off using Wireless
Assistant.
NOTE: Enabling or turning on a wireless device does not automatically connect the computer to a
network or a Bluetooth-enabled device.
To view the state of the wireless devices, click the Show hidden icons icon, the arrow at the left of the
notification area, and then position the mouse pointer over the wireless icon.
If the wireless icon is not displayed in the notification area, complete the following steps to change
Wireless Assistant properties:
1. Select Start > Control Panel > Hardware and Sound > Windows Mobility Center.
2. Click the wireless icon in the Wireless Assistant tile, which is located in the bottom row of Windows®
Mobility Center. Wireless Assistant opens.
3. Click Properties.
4. Select the check box next to HP Wireless Assistant icon in notification area.
5. Click Apply.
6. Click Close.
For more information, refer to the Wireless Assistant software Help:

2. Click the Help button.
Using operating system controls
Some operating systems also offer a way to manage integrated wireless devices and the wireless
connection. For example, Windows provides the Network and Sharing Center that allows you to set up
a connection or network, connect to a network, manage wireless networks, and diagnose and repair
network problems.
To access the Network and Sharing Center, 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.
Using a WLAN 15
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).
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 (ISP)
A wireless router (purchased separately) (2)
●
The wireless computer (3)
●
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, refer to the information provided by your router manufacturer or your
ISP.
16 Chapter 2 Wireless, local area network, and modem
Protecting your WLAN
Because the WLAN standard was designed with only limited security capabilities—basically to foil casual
eavesdropping rather than more powerful forms of attack—it is essential to understand that WLANs are
vulnerable to well-known and well-documented security weaknesses.
WLANs in public areas, or “hotspots,” like coffee shops and airports may not provide any security. New
technologies are being developed by wireless manufacturers and hotspot service providers that make
the public environment more secure and anonymous. If you are concerned about the security of your
computer in a hotspot, limit your network activities to noncritical e-mail and basic Internet surfing.
When you set up a WLAN or access an existing WLAN, always enable security features to protect your
network from unauthorized access. The common security levels are Wi-Fi Protected Access (WPA)Personal and Wired Equivalent Privacy (WEP). Because wireless radio signals travel outside the
network, other WLAN devices can pick up unprotected signals and either connect to your network
(uninvited) or capture information being sent across it. However, you can take precautions to protect
your WLAN:
Use a wireless transmitter with built-in security
●
Many wireless base stations, gateways, or routers provide built-in security features such as
wireless security protocols and firewalls. With the correct wireless transmitter, you can protect your
network from the most common wireless security risks.
Work behind a firewall
●
A firewall is a barrier that checks both data and requests for data that are sent to your network,
and discards any suspicious items. Firewalls are available in many varieties, both software and
hardware. Some networks use a combination of both types.
Use wireless encryption
●
A variety of sophisticated encryption protocols is available for your WLAN. Find the solution that
works best for your network security:
Wired Equivalent Privacy (WEP) is a wireless security protocol that encodes or encrypts all
◦
network data before it is transmitted using a WEP key. Usually, you can allow the network to
assign the WEP key. Alternatively, you can set up your own key, generate a different key, or
choose other advanced options. Without the correct key, others will not be able to use the
WLAN.
WPA (Wi-Fi Protected Access), like WEP, uses security settings to encrypt and decrypt data
◦
that is transmitted over the network. However, instead of using one static security key for
encryptions as WEP does, WPA uses “temporal key integrity protocol” (TKIP) to dynamically
generate a new key for every packet. It also generates different sets of keys for each computer
on the network.
Using a WLAN 17
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1. Be sure that the WLAN device is on. If it is on, the wireless light is white. If the wireless light is
amber, press the wireless action key (f12).
2. Click the network icon in the notification area, at the far right of the taskbar.
3. Select your WLAN from the list.
4. Click Connect.
If the network is a security-enabled WLAN, you are prompted to enter a network security key, which
is a security code. Type the code, and then click OK to complete the connection.
NOTE: If no WLANs are listed, you are out of range of a wireless router or access point.
NOTE: If you do not see the network 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. You
can choose 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 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.
More information about using a WLAN is available through the following resources:
Information from your ISP and the user guides included with your wireless router and other WLAN
●
equipment
Information and Web site links provided in Help and Support
●
For a list of public WLANs near you, contact your ISP or search the Web. Web sites that list public
WLANs include Cisco Internet Mobile Office Wireless Locations, Hotspotlist, and Geektools. Check with
each public WLAN location for cost and connection requirements.
Roaming to another network
When you move your computer within range of another WLAN, Windows attempts to connect to that
network. If the attempt is successful, your computer is automatically connected to the new network. If
Windows does not recognize the new network, follow the same procedure you used initially to connect
to your WLAN.
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)
●
18 Chapter 2 Wireless, local area network, and modem
Imaging devices (printer, camera)
●
Audio devices (headset, speakers)
●
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information on configuring and using Bluetooth devices, refer to the
Bluetooth software Help.
Bluetooth and Internet Connection Sharing (ICS)
HP does not recommend setting up one computer with Bluetooth as a host and using it as a gateway
through which other computers may connect to the Internet. When two or more computers are connected
using Bluetooth, and Internet Connection Sharing (ICS) is enabled on one of the computers, the other
computers may not be able to connect to the Internet using the Bluetooth network.
The strength of Bluetooth is in synchronizing information transfers between your computer and wireless
devices including cellular phones, printers, cameras, and PDAs. The inability to consistently connect
two or more computers to share the Internet through Bluetooth is a limitation of Bluetooth and the
Windows operating system.
Troubleshooting wireless connection problems
Some possible causes for wireless connection problems include the following:
Network configuration (SSID or security) has been changed.
●
Wireless device is not installed correctly or has been disabled.
●
Wireless device or router hardware has failed.
●
Wireless device encountered interference from other devices.
●
NOTE: Wireless networking devices are included with select computer models only. If wireless
networking is not listed in the feature list on the side of the original computer package, you may add
wireless networking capability to the computer by purchasing a wireless networking device.
Before working your way through the sequence of possible solutions to your network connection
problem, be sure that device drivers are installed for all wireless devices.
Use the procedures in this chapter to diagnose and repair a computer that does not connect to the
network you want to use.

Creating (burning) a CD or DVD
If your computer includes a CD-RW, DVD-RW, or DVD±RW optical drive, you can use software such
as Windows Media Player or CyberLink Power2Go to burn data and audio files, including MP3 and WAV
music files. To burn video files to a CD or DVD, use MyDVD.
Observe the following guidelines when burning a CD or DVD:
Before burning a disc, save and close any open files and close all programs.
●
A CD-R or DVD-R is usually best for burning audio files because after the information is copied, it
●
cannot be changed.
NOTE: You cannot create an audio DVD with CyberLink Power2Go.
Because some home and car stereos will not play CD-RWs, use CD-Rs to burn music CDs.
●
A CD-RW or DVD-RW is generally best for burning data files or for testing audio or video recordings
●
before you burn them to a CD or DVD that cannot be changed.
DVD players used in home systems usually do not support all DVD formats. Refer to the user guide
●
that came with your DVD player for a list of supported formats.
An MP3 file uses less space than other music file formats, and the process for creating an MP3
●
disc is the same as the process for creating a data file. MP3 files can be played only on MP3 players
or on computers with MP3 software installed.
To burn a CD or DVD, follow these steps:
1. Download or copy the source files into a folder on your hard drive.
2. Insert a blank CD or DVD into the optical drive.
3. Select Start > All Programs, and then select the name of the program you want to use.
NOTE: Some programs may be located in subfolders.
4. Select the kind of CD or DVD you want to create—data, audio, or video.
5. Right-click Start, click Open Windows Explorer, and navigate to the folder where the source files
are stored.
6. Open the folder, and then drag the files to the drive that contains the blank optical disc.
7. Initiate the burning process as directed by the program you have selected.
For specific instructions, refer to the software manufacturer's instructions, which may be provided with
the software, on disc, or on the manufacturer's Web site.
Observe the copyright warning. It is a criminal offense, under applicable copyright laws, to make

Adjusting webcam properties
You can adjust webcam properties using the Properties dialog box, which is accessible from various
programs that use the webcam, usually from a configuration, settings, or properties menu:
Brightness—Controls the amount of light that is incorporated into the image. A higher brightness
●
setting creates a brighter image; a lower brightness setting creates a darker image.
Contrast—Controls the difference between lighter and darker areas on the image. A higher
●
contrast setting intensifies the image; a lower contrast setting maintains more of the original
information’s dynamic range but leads to a flatter image.
Hue—Controls the aspect of color that distinguishes it from another color (what makes a color red,
●
green, or blue). Hue is distinct from saturation, which measures the intensity of the hue.
Saturation—Controls the strength of color in the final image. A higher saturation setting creates a
●
bolder image; a lower saturation setting creates a more subtle image.
Sharpness—Controls the definition of edges in an image. A higher sharpness setting creates a
●
more defined image; a lower sharpness setting creates a softer image.
Gamma—Controls the contrast affecting the mid-level grays or midtones of an image. Adjusting
●
the gamma of an image allows you to change the brightness values of the middle range of gray
tones without dramatically altering the shadows and highlights. A lower gamma setting makes
grays look black, and makes dark colors even darker.
Backlight Comp—Compensates in cases where a subject with a large amount of background light
●
would otherwise be obscured by streaking or silhouetting.
