Using a WLAN

A wireless connection connects the computer to Wi-Fi networks, or WLANs. A WLAN is composed of
other computers and accessories that are linked by a wireless router or a wireless access point.

16 Chapter 3 Networking

Connecting to an existing WLAN

1. Be sure that the WLAN device is on.

NOTE: Refer to Getting to know your computer on page 3 for information on identifying the

location of the wireless button and wireless light on your computer.

2. Click the Network Connection icon in the notification area, at the far right of the taskbar.

Available wireless networks are listed under Wireless Networks.

3. Click the correct wireless network.

If the network is a security-enabled WLAN, you are prompted to enter a network security code.
Type the code, and then click OK to complete the connection.

NOTE: To connect to a network that is not automatically detected, click the Network

Connection icon and select Connect to Hidden Wireless Network. Enter the ESSID information,

and set encryption parameters.

NOTE: If no WLANs are listed, and your network is not hidden, you are out of range of a wireless

router or access point.

If you do not see the network you want to connect to, right-click the Network Connection icon in
the notification area, at the far right of the taskbar, and click Edit Connections.

Setting up a new WLAN

Required 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.

NOTE: Some cable modems include a built-in router. Check with your ISP to see if you need a separate

router.

NOTE: When setting up a wireless connection, be sure that your computer and wireless router are

synchronized. To synchronize your computer and wireless router, turn your computer and wireless
router off and then back on.

As your network grows, additional wireless and wired computers can be connected to the network to
access the Internet.

Using a WLAN 17

For help in setting up your WLAN, refer to the information provided by your router manufacturer or your
ISP.

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 e-mail that is not confidential and basic Internet surfing.

Wireless radio signals travel outside the network, so other WLAN devices can pick up unprotected
signals. You can take the following precautions to protect your WLAN:

●

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.

●

Wireless encryption—Wi-Fi Protected Access (WPA and WPA2) encrypts and decrypts data
transmitted over the network. 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. Wired Equivalent Privacy (WEP) encrypts data before it is transmitted using a WEP
key. Without the correct key, others will not be able to use the WLAN.

Roaming to another network

When you move your computer within range of another WLAN, the operating system attempts to connect
to that network. If the attempt is successful, your computer is automatically connected to the new
network. If the operating system does not recognize the new network, follow the same procedure you
used initially to connect to your WLAN.

18 Chapter 3 Networking

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

●

Phones

●

Audio devices

The strength of Bluetooth is in synchronizing information transfers between your computer and wireless
devices. The inability to consistently connect two or more computers to share the Internet through
Bluetooth is a limitation of Bluetooth and the operating system.

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.

Connecting to a local area network (LAN)

Connecting to a local area network (LAN) requires an 8-pin, RJ-45 network cable (purchased
separately). If the network cable contains noise suppression circuitry (1), which prevents interference
from TV and radio reception, orient the circuitry end of the cable (2) toward the computer.

To connect the network cable:

1. Plug the network cable into the network jack (1) on the computer.

Using Bluetooth wireless devices (select models only) 19

2. Plug the other end of the cable into a network wall jack (2).

WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a

modem or telephone cable into the RJ-45 (network) jack.

Troubleshooting

The following sections describe several common issues and solutions.

The computer is unable to start up

If the computer does not turn on when you press the power button, the following suggestions may help
you determine why the computer does not start up:

●

If the computer is plugged into an AC outlet, plug another electrical device into the outlet to be sure
that the outlet is providing adequate power.

NOTE: Use only the AC adapter provided with the computer or one approved by HP for this

computer.

●

If the computer is plugged into an external power source other than an AC outlet, plug the computer
into an AC outlet using the AC adapter. Be sure that the power cord and AC adapter connections
are secure.

The computer screen is blank

If the screen is blank but you have not turned off the computer, one or more of these settings may be
the cause:

●

The computer may be in the Suspend state or in Hibernation. To exit Suspend or Hibernation,
briefly press the power button. Suspend and Hibernation are energy-saving features that turn off
the display. Suspend and Hibernation can be initiated by the system while the computer is on but
is not in use, or when the computer has reached a low battery level. To change these and other
power settings, right-click the Power icon in the notification area at the far right of the taskbar, and
then click Preferences.

●

The computer may not be set to display the image on the computer screen. To transfer the image
to the computer screen, press f4. On most models, when an optional external display, such as a
monitor, is connected to the computer, the image can be displayed on the computer screen or the
external display, or on both devices simultaneously. When you press f4 repeatedly, the image
alternates among the computer display, one or more external displays, and simultaneous display
on all devices.

place the computer directly on your lap or obstruct the computer air vents. Use the computer only on a
hard, flat surface. Do not allow another hard surface, such as an adjoining optional printer, or a soft
surface, such as pillows or rugs or clothing, to block airflow. Also, do not allow the AC adapter to contact
the skin or a soft surface, such as pillows or rugs or clothing, during operation. The computer and the
AC adapter comply with the user-accessible surface temperature limits defined by the International
Standard for Safety of Information Technology Equipment (IEC 60950).

NOTE: The fan in the computer starts up automatically to cool internal components and prevent

overheating. It is normal for the internal fan to cycle on and off during operation.

D Electrostatic discharge

Electrostatic discharge is the release of static electricity when two objects come into contact—for
example, the shock you receive when you walk across the carpet and touch a metal door knob.

A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components. To prevent damage to the computer, damage to a drive, or loss of information, observe
these precautions:

●

If removal or installation instructions direct you to unplug the computer, unplug it after being properly
grounded and before removing a cover.

●

Keep components in their electrostatic-safe containers until you are ready to install them.

●

Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.

●

Use nonmagnetic tools.

●

Before handling components, discharge static electricity by touching an unpainted metal surface
of the component.

●

If you remove a component, place it in an electrostatic-safe container.

If you need more information about static electricity or assistance with component removal or installation,
contact Customer Support.
