Connecting to Internet with an Android device
To turn on Wi-Fi, swipe down and tap Settings > Network & internet > Wi-Fi. If necessary, tap the button to turn Wi-Fi on. If networks are available, they will appear in the WI-FI NETWORKS list. Tap the name of the network (SSID in technical terms) you want to connect with and enter a password if necessary
On many public networks you may have to agree to Terms of Service as a part of the connection process. Be cautious—you should always assume public networks are not secure or private.
