FON is the largest WiFi community in the world. Members share their wireless Internet access at home and, in return, enjoy free WiFi wherever they find another FoneroРІР‚в„ўs Access Point. Thanks to the Fon Spot sofware you can create your own access point. To start the Fonspot though, you have to be connected to Internet through ethernet or 3G, never via Wifi because you'll share your connection using that interface.
