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 46.

wireless LAN installed computers to an AP.
