Configuring the Network Environment Settings
for Wireless LAN Network
(WLAN)
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 Page 4-18. Using
Network Services)
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 Page 4-10, ‘Connecting to an Access Point (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 Page 4-11, ‘Connecting to com-
puter-to-computer networks (peer-to-peer or ad hoc)’).
