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-827 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.
