Appendix A - Wireless Basics
There are basically two modes of networking: 
•  Infrastructure – All wireless clients will connect to an access point or wireless router.
•  Ad-Hoc – Directly connecting to another computer, for peer-to-peer communication, using wireless network adapters on each 
computer, such as two or more DIR-655 wireless network Cardbus adapters.
An Infrastructure network contains an Access Point or wireless router. All the wireless devices, or clients, will connect to the wireless router or access 
point. 
An Ad-Hoc network contains only clients, such as  laptops with wireless  cardbus adapters. All the  adapters must be  in Ad-Hoc  mode to 
communicate.
