2Wireless, modem, and local area
network
Using wireless devices (select models only)
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.
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.
NOTE:The specifications for the 802.11n WLAN are draft specifications and are not final. If the
final specifications differ from the draft specifications, it may affect the ability of the computer to
communicate with other 802.11n WLAN devices.

Using the wireless button
The computer has a wireless button, one or more wireless devices, and two wireless lights. 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
Wireless Assistant software (select models only) or through Computer Setup.
22Chapter 2 Wireless, modem, and local area network
NOTE: If the wireless devices are disabled by Computer Setup, the wireless button will not work until
you reenable your devices.
Using Wireless Assistant software (select models only)
A wireless device can be turned on or off using the Wireless Assistant software. If a wireless device is
disabled by Computer Setup, it must be reenabled by Computer Setup 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, follow either of these steps:
Position the cursor over the wireless icon in the notification area, at the far right of the taskbar.
– or –
Open Wireless Assistant by double-clicking the icon in the notification area.
For more information, refer to the Wireless Assistant software Help:
1.Open Wireless Assistant by double-clicking the icon in the notification area.
2.Click the Help button.
Using HP Connection Manager (select models only)
You can use HP Connection Manager to connect to WWANs using the HP Mobile Broadband device in
your computer (select models only).
To start Connection Manager, click the Connection Manager icon in the notification area, at the far
right of the taskbar.
For more details about using Connection Manager, refer to the Connection Manager software Help.
Using operating system controls
Some operating systems also offer a way to manage integrated wireless devices and the wireless
connection. For example, Windows® Network Connections allows you to set up a connection, connect
to a network, manage wireless networks, and diagnose and repair connections.
To access Network Connections, click Start > Control Panel > Network and Internet Connections>Network Connections.
For more information, refer to Help and Support. Click Start > Help and Support.
Using wireless devices (select models only)23
Using a WLAN device (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 following illustration 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
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.
24Chapter 2 Wireless, modem, and local area network
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 device (select models only)25
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 on. 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 Show all connections. 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 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.
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.

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. The computer includes 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 following “Inserting a SIM” and “Removing
a SIM” sections.
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

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.
30Chapter 2 Wireless, modem, and local area network

36Chapter 2 Wireless, modem, and local area network
Solving travel connection problems
If you experience modem connection problems when using the computer outside of the country or region
in which you purchased it, try the following suggestions.
Check the telephone line type.
●
The modem requires an analog, not a digital, telephone line. A line described as a PBX line is
usually a digital line. A telephone line described as a data line, fax machine line, modem line, or
standard telephone line is usually an analog line.
Check for pulse or tone dialing.
●
An analog telephone line supports one of 2 dialing modes: pulse dialing or tone dialing. These
dialing mode options are selected in the Phone and Modem Options settings. The dialing mode
option selected must match the dialing mode supported by the telephone line in your location.
To determine the dialing mode supported by a telephone line, dial a few digits on the telephone,
and then listen for clicks (pulses) or tones. Clicks indicate that the telephone line supports pulse
dialing. Tones indicate that the telephone line supports tone dialing.
To change the dialing mode in your current modem location setting, follow these steps:
1.Select Start > Control Panel > Printers and Other Hardware > Phone and Modem
Options.
2.Then click the Dialing Rules tab.
3.Select your modem location setting.
4.Click Edit.
5.Click either Tone or Pulse.
6.Click OK twice.
Check the telephone number you are dialing and the response of the remote modem.
●
Dial a telephone number, make sure there is a response from the remote modem, and then hang
up.
Set the modem to ignore dial tones.
●
If the modem receives a dial tone it does not recognize, it does not dial and displays a “No Dial
Tone” error message.
To set the modem to ignore all dial tones before dialing, follow these steps:
1.Select Start > Control Panel > Printers and Other Hardware > Phone and Modem
Options.
2.Then click the Modems tab.
3.Click the listing for the modem.
4.Click Properties.
5.Click Modem.
Using the modem (select models only)37
6.Clear the check box for Wait for dial tone before dialing.
7.Click OK twice.
38Chapter 2 Wireless, modem, and local area network
Connecting to a local area network (LAN)
Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased

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.
Webcam (select models only)67
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.

6Drives
Identifying installed drives
Your computer includes a hard drive (with a rotating disc) or a solid-state drive (SSD) with solid-state
memory. Because it has no moving parts, an SSD does not generate as much heat as a hard drive.
To view the drives installed on the computer, select Start > My Computer.
Handling drives
Drives are fragile computer components that must be handled with care. Refer to the following cautions
before handling drives. Additional cautions are included with the procedures to which they apply.
Identifying installed drives85
CAUTION:To reduce the risk of damage to the computer, damage to a drive, or loss of information,
observe these precautions:
Before you move a computer that is connected to an external hard drive, initiate Standby and allow the
screen to clear, or properly disconnect the external hard drive.
Before handling a drive, discharge static electricity by touching the unpainted metal surface of the drive.
Do not touch the connector pins on a removable drive or on the computer.
Handle a drive carefully; do not drop a drive or place items on it.
Before removing or inserting a drive, shut down the computer. If you are unsure whether the computer
is off, in Standby, or in Hibernation, turn the computer on and then shut it down through the operating
system.
Do not use excessive force when inserting a drive into a drive bay.
Do not type on the keyboard or move the computer while an optional optical drive is writing to a disc.
The write process is sensitive to vibration.
When the battery is the only source of power, be sure that the battery is sufficiently charged before
writing to media.
Avoid exposing a drive to temperature or humidity extremes.
Avoid exposing a drive to liquids. Do not spray the drive with cleaning products.
Remove media from a drive before removing the drive from the drive bay, or traveling with, shipping, or
storing a drive.
If a drive must be mailed, place the drive in a bubble-pack mailer or other suitable protective packaging
and label the package “FRAGILE.”
Avoid exposing a drive to magnetic fields. Security devices with magnetic fields include airport walkthrough devices and security wands. The airport security devices that check carry-on luggage, such as
conveyor belts, use X-rays instead of magnetism and will not damage a drive.
