There are two different ways to access Internet: 

1)   With a wireless adaptor, receiving and transferring signal via a wireless router, then passed 

to an ADSL modem, then to local ISP (Internet service supplier) through a telephone line.   

2)   With a wireless adaptor, receiving and transferring signal via local AP (Access Point) or so 

called Hotpoint directly. 

Tips: An 802.11 LAN is based on a cellular architecture where the system is subdivided into 

cells, where each cell (called Basic Service Set or BSS) is controlled by a Base Station 
(called Access Point, or in short AP)
