							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 configuring a wireless router, see the information provided by your router manufacturer or
your ISP.
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 HP Support Assistant. To access HP Support
Assistant, from the Start screen, select the HP Support Assistant app.
Connecting to a wireless network 21 
						

							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.From the Start screen, point to the far-right upper or lower corner of the screen to display the
charms.
3.Select Settings, and then click the network status icon.
4.Select your WLAN from the list.
5.Click Connect.
If the WLAN is a security-enabled WLAN, you are prompted to enter a security code. Type the
code, and then click Sign in.
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, from the Windows desktop, right-
click the network status icon, and then select Open Network and Sharing Center. 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.
6.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.

A Bluetooth device provides short-range wireless communications that replace the physical cable
connections that traditionally link electronic devices such as the following:
●Computers (desktop, notebook, PDA)
●Phones (cellular, cordless, smart phone)
●Imaging devices (printer, camera)
●Audio devices (headset, speakers)
●Mouse
Bluetooth devices provide peer-to-peer capability that allows you to set up a personal area network
(PAN) of Bluetooth devices. For information about configuring and using Bluetooth devices, see the
Bluetooth software Help.
Connecting to a wired network
Your computer has a local area network (LAN) wired connection. A LAN connection uses a network
cable which is sold separately.
22 Chapter 3   Connecting to a network 
						

							Connecting to a local area network (LAN)
Use a LAN connection if you want to connect the computer directly to a router in your home (instead
of working wirelessly), or if you want to connect to an existing network at your office.
Connecting to a LAN requires an 8-pin, RJ-45 network cable.
To connect the network cable, follow these steps:
1.Plug the network cable into the network jack (1) on the computer.
2.Plug the other end of the network cable into a network wall jack (2) or router.
NOTE:If the network cable contains noise suppression circuitry (3), which prevents
interference from TV and radio reception, orient the circuitry end of the cable toward the
computer.
Connecting to a wired network 23 
						

							4 Navigating using the keyboard, touch
gestures and pointing devices
Your computer allows navigation using touch gestures (select models only) in addition to the
keyboard and mouse. Touch gestures can be used on your computer TouchPad or on a touch screen
(select models only).
Select computer models have special action keys or hot key functions on the keyboard to perform
routine tasks.
Using pointing devices
NOTE:In addition to the pointing devices included with your computer, you can use an external
USB mouse (purchased separately) by connecting it to one of the USB ports on the computer.
Setting pointing device preferences
Use Mouse Properties in Windows to customize settings for pointing devices, such as button
configuration, click speed, and pointer options. You can also view demonstrations of TouchPad
gestures.
To access Mouse Properties:
●From the Start screen, type mouse, click Settings, and then select Mouse.
Using the TouchPad and gestures
The TouchPad allows you to navigate the computer screen and control the pointer by using simple
finger movements.
TIP:Use the left and right buttons on the TouchPad as you would use the corresponding buttons on
an external mouse.
NOTE:TouchPad gestures are not supported in all apps.

Identifying the hot keys
A hot key is a combination of the fn key and either the esc key, or one of the function keys.
To use a hot key:
▲Briefly press the fn key, and then briefly press the second key of the hot key combination.
Hot key combination Description
 fn+escDisplays system information.
fn+f3Initiates Sleep, which saves your information in system memory. The display and other system
components turn off and power is conserved.
