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)
The illustration below shows an example of a wireless network installation that is connected to the
Internet.
NOTE: Some modems have a built-in wireless router. Check with your ISP to determine what type
of modem you have.
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—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—Wi-Fi Protected Access (WPA and WPA2) encrypts and decrypts data
●
transmitted over the network. 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. Wired Equivalent Privacy (WEP) encrypts data before it is transmitted using a
WEP key. 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, the operating system attempts to
connect to that network. If the attempt is successful, your computer is automatically connected to the
Using a WLAN15
Page 24
new network. If the operating system does not recognize the new network, follow the same procedure
you used initially to connect to your WLAN.
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).
16Chapter 3 Networking
Page 25
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).
3.Plug the modem cable adapter (3) into the telephone wall jack.
Connecting to a local area network (LAN) (select models only)
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.
Connecting to a wired network17

Using battery power
When a charged battery is in the computer and the computer is not plugged into external power, the
computer runs on battery power. When a charged battery is in the computer and the computer is
plugged into external AC power, the computer runs on AC power.
If the computer contains a charged battery and is running on external AC power supplied through the
AC adapter, the computer switches to battery power if the AC adapter is disconnected from the
computer.
NOTE: When you disconnect AC power, the display brightness is automatically decreased to save
battery life. For information on increasing or decreasing display brightness, refer to
pointing devices on page 19.
You can keep a battery in the computer or in storage, depending on how you work. Keeping the
battery in the computer whenever the computer is plugged into AC power charges the battery and
also protects your work in case of a power outage. However, a battery in the computer slowly
discharges when the computer is off and unplugged from external power.
WARNING! To reduce potential safety issues, use only the battery provided with the computer, a
replacement battery provided by HP, or a compatible battery purchased from HP.
Computer battery life varies, depending on power management settings, programs running on the
computer, display brightness, external devices connected to the computer, and other factors.

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.

DElectrostatic discharge
Electrostatic discharge is the release of static electricity when two objects come into contact—for
example, the shock you receive when you walk across the carpet and touch a metal door knob.
A discharge of static electricity from fingers or other electrostatic conductors may damage electronic
components. To prevent damage to the computer, damage to a drive, or loss of information, observe
these precautions:
●If removal or installation instructions direct you to unplug the computer, unplug it after being
properly grounded and before removing a cover.
Keep components in their electrostatic-safe containers until you are ready to install them.
●
Avoid touching pins, leads, and circuitry. Handle electronic components as little as possible.
●
●Use nonmagnetic tools.
●Before handling components, discharge static electricity by touching an unpainted metal surface
of the component.
If you remove a component, place it in an electrostatic-safe container.
●
If you need more information about static electricity or assistance with component removal or
installation, contact Customer Support.
