							3Networking
Your computer supports two types of Internet access:
●Wireless—see 
Creating a wireless connection on page 16.
●Wired—see 
Connecting to a wired network on page 22.
NOTE:You must set up Internet service before you can connect to the Internet.
14 Chapter 3   Networking 
						

							Using an Internet service provider
Before you can connect to the Internet, you must establish an account with an Internet service
provider (ISP). To purchase Internet service and a modem, contact a local ISP. The ISP will help set
up the modem, install a network cable to connect your wireless computer to the modem, and test the
Internet service.
NOTE:Your ISP will give you a user ID and password to access the Internet. Record this
information and store it in a safe place.
The following features will help you set up a new Internet account or configure the computer to use an
existing account:
●Internet Services & Offers (available in some locations)—This utility assists with signing up
for a new Internet account and configuring the computer to use an existing account. To access
this utility, select Start > All Programs > Online Services > Get Online.
●ISP-provided icons (available in some locations)—These icons may be displayed either
individually on the Windows desktop or grouped in a desktop folder named Online Services. To
set up a new Internet account or configure the computer to use an existing account, double-click
an icon, and then follow the on-screen instructions.
●Windows Connect to the Internet Wizard—This wizard allows you to connect to the Internet in
any of the following situations:
◦You already have an account with an ISP.
◦You do not have an Internet account and want to select an ISP from the list provided within
the wizard. (The list of ISP providers is not available in all regions.)
◦You have selected an unlisted ISP, and the ISP has provided you with information such as
a specific IP address and POP3 and SMTP settings.
To access the Windows Connect to the Internet Wizard and instructions for using it, select
Start > Control Panel > Network and Internet > Network and Sharing Center.
NOTE:If you are prompted within the wizard to choose between enabling or disabling
Windows Firewall, choose to enable the firewall.

Creating a wireless connection 17 
						

							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.
Connecting to an existing WLAN
To connect to an existing WLAN:
1.Be sure that the WLAN device is on. (see 
Turning wireless devices on or off on page 17.)
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.
18 Chapter 3   Networking 
						

							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.
Configuring a wireless router
For help in setting up a WLAN, see 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.
Using a WLAN 19 
						

							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.
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.
