Connecting Through a Wireless LAN (Option)

A wireless network (Wireless LAN) environment is a network environment that

enables communication between multiple computers at home or a small-size office

through wireless LAN devices.

Using the wireless network connections between the systems, you can use normal

network functions such as sharing of files, folders and printers. Using computer-to-

computer network (ad hoc) connections, you can access the Internet through a

computer connected directly to the Internet even if your computer is not directly

connected to the Internet. For details, see “Using Network Services” on page 48.

The information provided in this section only applies to models equipped with

an optional wireless LAN device.

To turn off the Wireless LAN

If the wireless LAN is turned on, the computer consumes much power,

therefore shortening the amount of time you can run on battery. Therefore, if

you are not using the WLAN or if you are in an environment that does not

provided WLAN, you are recommended to turn off the WLAN by pushing the

WLAN/Bluetooth button (p15) on the computer.

Wireless network connections can be classified into two categories.

1) Access Point

You can connect to an AP to use the network. This is possible only in an environment

equipped with an AP. For details, see “Connecting to an Access Point (AP)” on page

38.

What is an Access Point (AP)?

An AP is a network device that bridges wired and wireless LANs, and

corresponds to a wireless hub in a wired network. You can connect multiple

wireless LAN installed computers to an AP.

2) Computer-to-computer (ad hoc)

This is also called a peer-to-peer or ad hoc network.

In computer-to-computer wireless networks, you can wirelessly connect 2 or more

computers that have wireless LAN modules. Using computer-to-computer wireless

networks, you can access the Internet through a computer that is connected to the

Internet even if your computer is not directly connected to the Internet. For details, see

“Connecting to computer-to-computer networks (peer-to-peer or ad hoc)” on page 39.

Connecting to an Access Point (AP)

This section describes how to connect to an AP. You can use the network when you are

connected to an AP.

In this section, the configuration procedures are described for Windows XP

installed computers. For information on the configuration procedures for other

operating systems, see “Using Wireless Networks in Other Operating

Systems” on page 44. Please ask your network administrator about detailed

configuration information such as the network key (encryption key).

1. Right-click on the Wireless Network Connection ( ) icon on the taskbar, and

select View Available Wireless Networks.

2. Select your desired AP (e.g. Test) to connect, and enter the encryption key for the

AP in the Network key field, and click Connect.

Connecting to the Internet 39

If the network key is not configured for the desired AP, select 'Allow me to

connect to the selected wireless network, even though it is not secure’.

Now you are connected to the AP, and you can access the network.

Checking the connection status

Move the mouse pointer over the Wireless Network Connection ( ) icon on

the taskbar, and the connection status is displayed.

Connecting to computer-to-computer networks (peer-to-peer or

ad hoc)

In computer-to-computer wireless networks, you can wirelessly connect 2 or more

computers that have wireless LAN modules.

You can connect by completing the following steps:

x Step 1. Set up a computer-to-computer network on a computer.

x Step 2. Connect to the configured computer from other computers.

In this section, the configuration procedures are described for Windows XP

installed computers. For information on the configuration procedures for other

operating systems, see “Using Wireless Networks in Other Operating

Systems” on page 44.

6. Enter the network name (e.g. samsung), and unselect 'The key is provided for me

automatically'. Enter the encryption key in the Network key field, and click OK.

To prevent a network connection from an unauthorized user, it would be better

to configure a network key (encryption key). A network key consists of 5 or 13

alphanumeric characters (e.g. magic), or of 10 or 26 hexadecimal numbers (a

hexadecimal number is represented by numbers '0' to '9' or letters 'a' to 'f').
