2.Wireless LAN basics
Wireless LAN network defined by IEEE 802.11b standard committee could be configured as:
•Ad Hoc wireless LAN, or
•Infrastructure wireless LAN.
Ad Hoc network is a group of notebooks with wireless LAN PC card called a BSS (Basic Service Set). These notebooks use their wireless LAN PC cards to communicate with each other, and notebooks cannot connect to the Internet.

The most obvious differentiation between Infrastructure wireless network and Ad Hoc wireless network is that the notebooks in Infrastructure wireless network can make use of the resource in the Internet through Access Point.

To set up your notebook’s network as the type of “Ad Hoc” or “Infrastructure” wireless network depends completely on your requirement. Generally, if your network environment has an Access Point, we recommend that you set it as “Infrastructure” to connect to the Internet.
