❑
An infrastructure network is one that extends an existing wired local
network to wireless devices by providing an access point. The access point
bridges the wireless and wired LAN and acts as a central controller for the
Wireless LAN. The access point coordinates transmission and reception
from multiple wireless devices within a specific range.
❑
A computer-to-computer (ad-hoc) network is one in which a local network is
created only by the wireless devices themselves, with no other central
controller or access point. Each device communicates directly with other
devices in the network. You can set up an ad-hoc network easily at home.
To connect to an existing wireless network
1 Move the Wireless LAN switch to ON or insert a Wireless LAN PC Card
into the PC Card slot. See "Inserting PC Cards" for more information.
