About Wi-Fi®

Wi-Fi is a generic term used to describe wireless Internet access. A Wi-Fi enabled device (such as a computer, laptop, mobile phone, or e-reader) can connect wirelessly to the Internet if it is in range of a wireless network. Wi-Fi enabled devices connect to the wireless network through access points (or hotspots). Access points can be public (such as at a library, restaurant or bookstore) or can be private (such as at home, work or school). 

Public Wi-Fi access points usually don't require a password, but instead require a user to acknowledge terms of use. 

Private Wi-Fi access points are usually password protected. Home Internet connection is usually provided by a cable or telephone company, and the wireless access is provided by a small device called a wireless router that is physically connected to the Internet.
