WiFi is a wireless network allowing you to connect your device to the Internet. Almost all devices today are WiFi-enabled and let you connect to the Internet wirelessly – laptops, tablets, smartphones, computers, gaming consoles, MP3 players, etc. If you have an old device and don’t know if your device is WiFi-enabled, check your manufacturer's specifications for support. You can also check your available network connections. If wireless is available, (and you may need to turn WiFi on) the list of wireless network names (SSIDs) will be displayed.
