●Operating system controls
Using the wireless key
The computer has a wireless key, one or more wireless devices, and one or two wireless lights,
depending on the model. All of the wireless devices on the computer are enabled at the factory, so
the wireless light illuminates 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 illuminates white, at least one wireless device is on. If the
wireless light is off, all wireless devices are off.
NOTE:On some models, the wireless light illuminates amber when all wireless devices are off.
Because the wireless devices are enabled at the factory, use the wireless key to turn on or turn off
the wireless devices simultaneously. Individual wireless devices are controlled through HP Wireless
Assistant.

							Using a WLAN
With a WLAN device, access is available to 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 accommodate a large number of computers and accessories and can separate critical
network functions.
●A home or small office WLAN 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 the computer, 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:
●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, see the information provided by your router manufacturer or your
ISP.
Using a WLAN 17 
						

							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 might 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
the computer in a hotspot, limit your network activities to noncritical e-mail and basic Internet surfing.
When setting 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. To protect the 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 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. The network assigns the WEP key,
but you can set up your own key, generate a different key, or choose other advanced
options. Without the correct key, others cannot access 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.

							Connecting to a WLAN
To connect to the WLAN:
1.Be sure that the WLAN device is on. If it is on, the wireless light is illuminated white. If the
wireless light is off, press the wireless key.
NOTE:On some models, the wireless light is amber when all wireless devices are off.
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.
NOTE:If no WLANs are listed, you are out of range of a wireless router or access point.
●If the network is a security-enabled WLAN, enter a network security key at the prompt,
which is a security code, and then click OK to complete the connection.
●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 appears.
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
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:
●Your ISP and the user guides included with the wireless router and other WLAN equipment
●Help and Support information and website links
For a list of public WLANs near you, contact your ISP or search the Web. Websites 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 the computer within range of another WLAN, Windows attempts to connect to that
network. If the attempt is successful, the computer is automatically connected to the new network. If
Windows does not recognize the new network, follow the instructions in “Connecting to a 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:
●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, see the
Bluetooth software Help.
Bluetooth and Internet Connection Sharing (ICS)
HP does not recommend setting up a host, Bluetooth computer and using it as a gateway through
which other computers 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 cannot connect to the Internet using the Bluetooth network.
The strength of Bluetooth is in synchronizing information transfers between the 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.
20 Chapter 2   Wireless, local area network, and modem 
						

							Connecting to a local area network
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.
WARNING!To reduce the risk of electric shock, fire, or damage to the equipment, do not connect a
modem or telephone cable to the RJ-45 (network) jack.
To connect the network cable:
1.Connect the network cable to the network jack (1) on the computer.
2.Connect the other end of the cable to a network wall jack (2).
