HP Pavilion Dm4 3000 Entertainment Notebook Pc Series Manual

							Connecting to an existing WLAN
To connect to an existing WLAN:
1.Be sure that the WLAN device is on. (Refer to 
Turning wireless devices on or off on page 20.)
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 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 WLAN 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, you can 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.
Setting up a new WLAN network
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)
●Your new 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 shows an example of a completed WLAN 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.
Using a WLAN 21 
						

							Configuring a wireless router
For help in setting up a WLAN, refer to the information provided by your router manufacturer or your
ISP.
The Windows operating system also provides tools to help you set up a new wireless network. To use
the Windows tools to set up your network, select Start > Control Panel > Network and Internet >
Network and Sharing Center > Set up a new connection or network > Set up a new network.
Then follow the on-screen instructions.
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, you can disconnect the cable, and then access the Internet through your wireless network.
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—A 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—Your computer supports three encryption protocols:
◦Wi-Fi Protected Access (WPA)
◦Wi-Fi Protected Access II (WPA2)
◦Wired Equivalent Privacy (WEP)
NOTE:HP recommends that you select WPA2, which is the most advanced of the three encryption
protocols. The use of WEP encryption is not recommended, because it can be overcome with little
effort.
●Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) use security standards to
encrypt and decrypt data transmitted over the network. Both WPA and WPA2 dynamically
generate a new key for every packet, and they also generate a different set of keys for each
computer network. To accomplish this:
◦WPA uses Advanced Encryption Standard (AES) and Temporal Key Integrity Protocol
(TKIP)
◦WPA2 uses Cipher Block Chaining Message Authentication Code Protocol (CCMP), which
is a new AES protocol.
●Wired Equivalent Privacy (WEP) encrypts data with a WEP key before it is transmitted. Without
the correct key, others will not be able to use the WLAN.
22 Chapter 4   Networking 
						

							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
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
●Imaging devices (cameras and printers)
●Audio devices
●Mouse
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.
Using Bluetooth wireless devices 23 
						

							Connecting to a wired network
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.
2.Plug the other end of the network cable into a network wall jack (2) or router.
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not plug a
modem cable or telephone cable into an RJ-45 (network) jack.

							Using the keyboard
Using the action keys
An action key performs an assigned function. The icon on each of the f1 through f4 keys and f6
through f12 keys illustrates the assigned function for that key.
To use an action key function, press and hold the key.
The action key feature is enabled at the factory. You can disable this feature in Setup Utility (BIOS)
and revert back to standard settings by pressing the fn key and an action key to activate the assigned
function. Refer to 
Using Setup Utility (BIOS) on page 88 for instructions.
CAUTION:Use extreme care when making changes in Setup Utility. Errors can prevent the
computer from operating properly.
Icon Key Description
f1Opens Help and Support, which provides tutorials, information about your Windows
operating system and computer, answers to questions, and updates to your computer.
Help and Support also provides automated troubleshooting tools and access to
customer support.
f2Decreases the screen brightness level incrementally as long as you hold down the
key.
f3Increases the screen brightness level incrementally as long as you hold down the key.
f4Switches the screen image among display devices connected to the system. For
example, if a monitor is connected to the computer, pressing this key alternates the
screen image from the computer display to the monitor display to a simultaneous
display on both the computer and the monitor.
Most external monitors receive video information from the computer using the external
VGA video standard. This action key can also alternate images among other devices
that are receiving video information from the computer.
f5Turns the keyboard backlight on or off (select models only).
NOTE:The keyboard backlight is turned on at the factory. To extend battery life,
turn off the keyboard backlight.
f6Plays the previous track of an audio CD or the previous section of a DVD or a BD.
f7Plays, pauses, or resumes a track of an audio CD or a section of a DVD or a BD.
f8Plays the next track of an audio CD or the next section of a DVD or a BD.
