Connected Wi-Fi
You can enable or disable Wi-Fi under "Settings > Wi-Fi". Choose a network connection after enabling Wi-Fi. If a Wi-Fi network is encrypted then is displayed and you need to enter the password. When your phone is connected to a Wi-Fi network, the signal strength of the Wi-Fi network will be displayed in the status bar at the top of the screen. The more bars you see, the stronger the signal. If there is no Wi-Fi network available, or you have disabled Wi-Fi, your phone will try to connect to the Internet via a cellular data network. Once your phone is connected to a Wi-Fi network, it will connect to the network automatically when in range. If more than one previously used Wi-Fi network is in range, your phone will connect to the most recently used network.
Add network
If you want to add a Wi-Fi network that is not in the list of available networks, please choose "Add network" and enter network SSID. You need to know the network name, password and security type before connecting to it.
Advanced settings
For advanced settings on a Wi-Fi network, you can press the [Menu button] and tap "Advanced settings".
