Using a WLAN
With a WLAN device, you can access 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.
16 Chapter 3 Connecting to a network
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 can accommodate a large number of computers and accessories and can separate critical
network functions.
A home or small office WLAN typically 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 your computer, you must connect to a WLAN infrastructure (provided
through a service provider or a public or corporate network).
Using an Internet service provider
When you are setting up Internet access in your home, 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 a password to use for Internet access. Record this
information and store it in a safe place.
Setting up a WLAN
To set up a WLAN and connect to the Internet, you need the following equipment:
A broadband modem (either DSL or cable) (1) and high-speed Internet service purchased from
●
an Internet service provider
A wireless router (2) (purchased separately)
●
A 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 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.
Configuring a wireless router
For help in setting up a WLAN, see the information provided by your router manufacturer or your ISP.
Connecting to a wireless network 17
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, disconnect the cable, and 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. Take the following precautions to protect your WLAN:
Use a 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.
Use wireless encryption.
●
Wireless encryption uses security settings to encrypt and decrypt data that is transmitted over
the network. For more information, access Help and Support by selecting Start > Help and
Support.
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1. Be sure that the WLAN device is on. If the device is on, the wireless light is on. If the wireless
light is off, press the wireless button.
NOTE: On some models, the wireless light is amber when all wireless devices are off.
2. Click the network status icon in the notification area, at the far right of the taskbar.
3. Select a WLAN to connect to.
4. Click Connect.
If the WLAN is a security-enabled WLAN, you are prompted to enter a security code. Type the
code, and then click OK to complete the connection.
NOTE: If no WLANs are listed, you may be 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,
allowing you to manually search for and connect to a network or to create a new network
connection.
5. Follow the on-screen instructions to complete the connection.
After the connection is made, place the mouse pointer over the network status 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 Connecting to a network
Using HP Mobile Broadband (select models only)
HP Mobile Broadband enables your computer to use 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 (called a mobile network operator), which in most cases is a cellular phone
network operator. Coverage for HP Mobile Broadband is similar to cellular phone voice coverage.
When used with mobile network operator 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.
HP supports the following technologies:
HSPA (High Speed Packet Access), which provides access to networks based on the Global
●
System for Mobile Communications (GSM) telecommunications standard.
EV-DO (Evolution Data Optimized), which provides access to networks based on the code
●
division multiple access (CDMA) telecommunications standard.
You may need the HP Mobile Broadband Module serial number to activate mobile broadband service.
The serial number is printed on a label inside the battery bay of your computer.
Some mobile network operators require the use of a SIM. A SIM contains basic information about
you, such as a personal identification number (PIN), as well as network information. Some computers
include a SIM that is preinstalled in the battery bay. If the SIM is not preinstalled, it may be provided
in the HP Mobile Broadband information provided with your computer or the mobile network operator
may provide it separately from the computer.
For information about inserting and removing the SIM, see the
on page 19 section in this chapter.
For information about HP Mobile Broadband and how to activate service with a preferred mobile
network operator, see the HP Mobile Broadband information included with your computer. For
additional information, go to the HP website at

Using antivirus software
When you use the computer to access e-mail, a network, or the Internet, you potentially expose it to
computer viruses. Computer viruses can disable the operating system, programs, or utilities, or cause
them to function abnormally.
Antivirus software can detect most viruses, destroy them, and, in most cases, repair any damage they
have caused. To provide ongoing protection against newly discovered viruses, antivirus software
must be kept up to date.
For more information about computer viruses, type viruses in the Search box in Help and Support.
Using firewall software
Firewalls are designed to prevent unauthorized access to a system or network. A firewall can be a
software program you install on your computer and/or network, or it can be a solution made up of
both hardware and software.
There are two types of firewalls to consider:
Host-based firewalls—Software that protects only the computer it is installed on.
●
Network-based firewalls—Installed between your DSL or cable modem and your home network
●
to protect all the computers on the network.
When a firewall is installed on a system, all data sent to and from the system is monitored and
compared with a set of user-defined security criteria. Any data that does not meet those criteria is
blocked.
Your computer or networking equipment may already have a firewall installed. If not, firewall software
solutions are available.
NOTE: Under some circumstances a firewall can block access to Internet games, interfere with
printer or file sharing on a network, or block authorized e-mail attachments. To temporarily resolve the
problem, disable the firewall, perform the task that you want to perform, and then reenable the
firewall. To permanently resolve the problem, reconfigure the firewall.

A Traveling with or shipping your
computer
If you have to travel with or ship your computer, here are some tips to keep in mind to keep your
equipment safe.
● Prepare the computer for traveling or shipping:
Back up your information to an external drive.
◦
Remove all discs and all external media cards, such as digital storage cards, from the
◦
computer.
◦ Turn off, and then disconnect all external devices.
Shut down the computer.
◦
Take along a backup of your information. Keep the backup separate on the computer.
●
● When traveling by air, carry the computer as hand luggage; do not check it in with the rest of
your bags.
CAUTION: Avoid exposing a drive to magnetic fields. Security devices with magnetic fields
include airport walk-through devices and security wands. Airport conveyer belts and similar
security devices that check carry-on baggage use X-rays instead of magnetism and do not
damage drives.
If you plan to use the computer during a flight, listen for the in-flight announcement that tells you
●
when you are allowed to use your computer. In-flight computer use is at the discretion of the
airline.
If you are shipping the computer or a drive, use suitable protective packaging and label the
●
package “FRAGILE.”
If the computer has a wireless device installed, the use of these devices may be restricted in
some environments. Such restrictions may apply onboard aircraft, in hospitals, near explosives,
and in hazardous locations. If you are uncertain of the policy that applies to the use of a
particular device, ask for authorization to use your computer before you turn it on.
If you are traveling internationally, follow these suggestions:
●
Check the computer-related customs regulations for each country or region on your
◦
itinerary.
Check the power cord and adapter requirements for each location in which you plan to use
◦
the computer. Voltage, frequency, and plug configurations vary.
WARNING! To reduce the risk of electric shock, fire, or damage to the equipment, do not
attempt to power the computer with a voltage converter kit sold for appliances.
