What does Wi-Fi connect a mobile device to?

Wi-Fi connects a device to a local wireless network, usually through a router or access point, for internet or local-network access.

A device may reconnect automatically to a successfully joined network. Use “Forget” or “Remove” to delete saved credentials, such as when the password changes.
