Wi-Fi is useful for many reasons, including:
- Freedom to access the Internet from anywhere within the signal range and move your devices around your home - anywhere within the Wi-Fi signal range - without losing your connection. Take any mobile device, like a laptop, into any room and still have Internet access, with no extra work required.
- Ability to access other devices connected to your network. For example, multiple computers can use one printer without a directly wired connection.
- Access to the Internet on devices like smartphones and tablets to download books, music, movies and apps, or surf the web.
- Freedom from the hassle of installing wired connections in different rooms.
