6. How does Wi-Fi work?
Each Wi-Fi enabled device searches for a Wi-Fi base station located nearby.
If it finds a network, you can connect to it by providing the correct password. Some networks are not password protected and your device will connect immediately. The access points are called 'Hot spots'.
The Wi-Fi base station usually takes the form of a network router / ADSL modem. This router is often connected directly to the internet on a standard ADSL telephone line. This is why you are able to connect to the internet using Wi-Fi.
