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. (Refer to 
Turning wireless devices on or off on page 3.)
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
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)
4 Chapter 2   Networking (select models only) 
						

							NOTE:Some cable modems include a built-in router. Check with your ISP to see if you need a
separate router.
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
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.
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—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
Using a WLAN 5 
						

							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.
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, which in most cases is a mobile phone
network provider.
When used with mobile network provider 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.
NOTE:You may need the HP Mobile Broadband Module serial number to activate mobile
broadband service. Refer to the Getting Started guide for the location of the serial number label.
Some mobile network service providers require the use of a subscriber identity module (SIM). A SIM
contains basic information about you, such as a personal identification number (PIN), as well as
network information. Some computers include a preinstalled SIM. If the SIM is not preinstalled, it may
be included with the HP Mobile Broadband information provided with your computer, or it may be
provided separately by the mobile network service provider.
For information on inserting and removing the SIM, refer to 
Inserting a SIM on page 6 and
Removing a SIM on page 7.
For information on HP Mobile Broadband and how to activate service with a preferred mobile network
service provider, refer to the HP Mobile Broadband information included with your computer. For
additional information, see the HP Web site at 
http://www.hp.com/go/mobilebroadband (U.S. only).

Using GPS (select models only) 7 
						

							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.
Connecting to a wired network
Using a modem (select models only)
A modem must be connected to an analog telephone line using a 6-pin, RJ-11 modem cable
(purchased separately). In some countries or regions, a specific modem cable adapter is also
required. Jacks for digital PBX systems may resemble analog telephone jacks, but they are not
compatible with the modem.
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.
If the modem 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.

							Connecting a modem cable
1.Plug the modem cable into the modem jack (1) on the computer.
2.Plug the modem cable into the RJ-11 telephone wall jack (2).
Connecting a country- or region-specific modem cable adapter
Telephone jacks vary by country or region. To use the modem and the modem cable outside the
country or region in which you purchased the computer, you must obtain a country- or region-specific
modem cable adapter.
To connect the modem to an analog telephone line that does not have an RJ-11 telephone jack,
follow these steps:
1.Plug the modem cable into the modem jack (1) on the computer.
2.Plug the modem cable into the modem cable adapter (2).
Connecting to a wired network 9 
						

							3.Plug the modem cable adapter (3) into the telephone wall jack.

1.Select Start > Control Panel.
2.Click Clock, Language, and Region.
3.Click Region and Language.
4.Click the Location tab to display your location.
Adding new locations when traveling
On a new computer, the only location setting available to the modem is a location setting for the
country or region in which you purchased the computer. As you travel to different countries or
regions, set the internal modem to a location setting that meets the operating standards of the country
or region in which you are using the modem.
As you add new location settings, they are saved by the computer so that you can switch among
settings at any time. You can add multiple location settings for any country or region.
CAUTION:To reduce the risk of losing your home country or region settings, do not delete your
current modem country or region settings. To enable modem use in other countries or regions while
preserving your home country or region configuration, add a new configuration for each location in
which you will use the modem.
CAUTION:To reduce the risk of configuring the modem in a way that violates the
telecommunications regulations and laws of the country or region you are visiting, select the country
or region in which the computer is located. The modem may not function properly if the correct
country or region selection is not made.
