2Wireless and local area network
Using wireless devices
Wireless technology transfers data across radio waves instead of wires. Your computer is 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.
HP Mobile Broadband Module—A wireless wide area network (WWAN) device that provides
●
access to information wherever mobile network operator service is available. In a WWAN, each
mobile device communicates to a mobile network operator’s base station. Mobile network operators
install networks of 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.
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.

model. All of the wireless devices on your computer are enabled at the factory, so the wireless light is
on (blue) 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 blue, 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 the
operating system controls.
NOTE: If the wireless devices are disabled by Computer Setup, the wireless button will not work until
you reenable your devices.

Using a WLAN (select models only)
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.
NOTE: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.
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
16Chapter 2 Wireless and local area network
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) 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, and 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
then 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 uses a WEP key to
◦
encode or encrypt all network data before it is transmitted. 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.
Close your network
●
If possible, prevent your network name (SSID) from being broadcast by the wireless transmitter.
Most networks initially broadcast the name, telling any computer nearby that your network is
available. By closing the network, other computers are less likely to know that your network exists.
NOTE:If your network is closed and the SSID is not broadcast, you will need to know or remember
the SSID to connect new devices to the network. Write down the SSID and store it in a secure
place before closing the network.
Using a WLAN (select models only)17
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1.Be su r e t h a t the WLAN device is on. If it is on, t h e wireless light is blue. If the wireless light is amber,
press the wireless button.
2.Select Start > Connect to.
3.Select your WLAN from the list, and then type the network security key, if required.
If the network is unsecured, meaning that anyone can access the network, a warning is
●
displayed. Click Connect Anyway to accept the warning and complete the connection.
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 Connect 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 Set up a connection or
network. A list of options will appear that includes creating a new network connection, as well as
troubleshooting connection issues.
After the connection is made, place the cursor 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.
More information about using a WLAN is available through the following resources:
Information from your ISP and the manufacturer's instructions 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.
For additional information on connecting your computer to a corporate WLAN, contact your network
administrator or IT department.
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.
18Chapter 2 Wireless and local area network
Using HP Mobile Broadband (select models only)
HP Mobile Broadband enables your computer to use wireless wide area networks (WWANs) to access
the Internet from more places and over larger areas than it can by using WLANs. Using HP Mobile
Broadband requires a network service provider (called a mobile network operator), which in most cases
is a mobile phone network operator. Coverage for HP Mobile Broadband is similar to mobile phone voice
coverage.
When used with mobile network operator service, HP Mobile Broadband gives you the freedom to stay
connected to the Internet, send e-mail, or connect to your corporate network whether you are on the
road or outside the range of Wi-Fi hotspots.
HP supports the following technologies:
HSPA (High Speed Packet Access), which provides access to networks based on the Global
●
System for Mobile Communications (GSM) telecommunications standard.
EV-DO (Evolution Data Optimized), which provides access to networks based on the code division
You may need the HP Mobile Broadband Module serial number to activate mobile broadband service.
The serial number is printed on a label inside the battery bay of your computer.
Some mobile network operators require the use of a subscriber identity module (SIM). A SIM contains
basic information about you, such as a PIN (personal identification number), as well as network
information. Some computers include a SIM that is preinstalled in the battery bay. If the SIM is not
preinstalled, it may be provided in the HP Mobile Broadband information provided with your computer
or the mobile network operator may provide it separately from the computer.
For information on inserting and removing the SIM, refer to the “Inserting a SIM” and “Removing a SIM”
sections in this chapter.
For information on HP Mobile Broadband and how to activate service with a preferred mobile network
operator, refer to the mobile broadband information included with your computer. For additional
information, see the HP Web site at
Inserting a SIM
CAUTION:When inserting a SIM, position the card with the slanted corner as shown in the illustration.
If a SIM is inserted backwards or upside down, the battery may not snap into place properly and could
damage the SIM and the SIM connector.
To prevent damage to the connectors, use minimal force when inserting a SIM.
To insert a SIM:
1.Shut down the computer. If you are not sure whether the computer is off or in Hibernation, turn the
computer on by pressing the power button. Then shut down the computer through the operating
system.
2.Close the display.

Using a Bluetooth wireless device
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)
●
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.
22Chapter 2 Wireless and local area network
Troubleshooting wireless connection problems

Current network security codes are unavailable
If you are prompted for a network key or an SSID when connecting to a WLAN, the network is protected
by security. You must have the current codes to make a connection on a secure network. The SSID and
network key are alphanumeric codes that you enter into your computer to identify your computer to the
network.
For a network connected to your personal wireless router, review the router user guide for
●
instructions on setting up the same codes on both the router and the WLAN device.
For a private network, such as a network in an office or at a public Internet chat room, contact the
●
network administrator to obtain the codes, and then enter the codes when prompted to do so.
Some networks change the SSID or network keys used in their routers or access points on a regular
basis to improve security. You must change the corresponding code in your computer accordingly.

broadcasts, and sound recordings. Do not use this computer for such purposes.
If your external optical drive is a CD-RW, DVD-RW, or DVD±RW optical drive, you can use software
such as Windows Media Player to burn data and audio files, including MP3 and WAV music files.
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.
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 external optical drive.

●
Adjusting webcam properties
You can adjust webcam properties using the Properties dialog box, which is accessible from various
programs that use the integrated 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.
For information about using the webcam, select Start > Help and Support.

Protecting the computer
NOTE:Security solutions are designed to act as deterrents. These deterrents may not prevent a
product from being mishandled or stolen.
Security features provided with your computer can protect the computer, personal information, and data
from a variety of risks. The way you use your computer will determine which security features you need
to use.
The Windows® operating system offers certain security features. Additional security features are listed
in the following table. Most of these additional security features can be configured in the Computer Setup
utility (referred to hereafter as Computer Setup).
To protect againstUse this security feature

Using passwords
Most security features use passwords. Whenever you set a password, write down the password and
store it in a secure location away from the computer. Note the following password considerations:
Setup and DriveLock passwords are set in Computer Setup and are managed by the system BIOS.
●
The embedded security password, which is an HP ProtectTools Security Manager password, can
●
be enabled in Computer Setup to provide BIOS password protection in addition to their normal HP
ProtectTools functions. The embedded security password is used with the optional embedded
security chip.
Windows passwords are set only in the Windows operating system.
●
If you forget the BIOS administrator password set in Computer Setup, you can use HP SpareKey
●
to access the utility.
If you forget both the DriveLock user password and the DriveLock master password set in Computer
●
Setup, the hard drive that is protected by the passwords is permanently locked and can no longer
be used.
You can use the same password for a Computer Setup feature and for a Windows security feature. You
can also use the same password for more than one Computer Setup feature.
Use the following tips for creating and saving passwords:
When creating passwords, follow requirements set by the program.
●
Write down your passwords and store them in a secure place away from the computer.
●
Do not store passwords in a file on the computer.
●
The following tables list commonly used Windows and BIOS administrator passwords and describe their
functions.

used to set the password), and then press enter. After 3 unsuccessful attempts to enter the BIOS
administrator password, you must restart the computer and try again.
Using Computer Setup DriveLock
CAUTION:To prevent the DriveLock-protected hard drive from becoming permanently unusable,
record the DriveLock user password and the DriveLock master password in a safe place away from your
computer. If you forget both DriveLock passwords, the hard drive will be permanently locked and can
no longer be used.
DriveLock protection prevents unauthorized access to the contents of a hard drive. DriveLock can be
applied only to the internal hard drive(s) of the computer. After DriveLock protection is applied to a drive,
a password must be entered to access the drive. The drive must be inserted into the computer or an
advanced port replicator in order for it to be accessed by the DriveLock passwords.
To apply DriveLock protection to an internal hard drive, a user password and a master password must
be set in Computer Setup. Note the following considerations about using DriveLock protection:
After DriveLock protection is applied to a hard drive, the hard drive can be accessed only by entering
●
either the user password or the master password.
The owner of the user password should be the day-to-day user of the protected hard drive. The
●
owner of the master password may be either a system administrator or the day-to-day user.
The user password and the master password can be identical.
●
You can delete a user password or master password only by removing DriveLock protection from
●
the drive. DriveLock protection can be removed from the drive only with the master password.
