Configuring the Network Environment Settings
for Wireless LAN Network
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.
When a computer-to-computer network has been constructed, a computer
that is not connected to the Internet can share the Internet by accessing
another computer connected to the Internet. (See P. 4-21. Using Network
Services)

when your computer has a wireless LAN (WLAN) device.
To view the installed wireless LAN card, click Start > Control Panel > Performance

according to the installed device and the connection state.
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 environ-
ment equipped with an AP. (See P. 4-10, 'Connecting to an Access Point (AP)')

What is an Access Point (AP)?
An AP is a network device that bridges wired and wireless LANs, and corre-
sponds 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 network.
In computer-to-computer wireless networks, you can wirelessly connect 2 or more
computers that have wireless LAN modules. (See P. 4-11, 'Connecting to
computer-to-computer networks (peer-to-peer or ad hoc)').
