3Flick the list and touch to select a Wi-Fi network you want to connect to.
4Enter a password (if necessary), then touch Connect to connect to the Wi-Fi network.
NOTE: To connect to a network protected by Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2, or Wireless Protected Setup (WPS), you must enter the WEP/WPA/WPA2/WPS security key to obtain authorized access to the network. The next time your device connects to a previously accessed secured wireless network, you will not be asked to enter the WEP/WPA/WPA2/WPS key again, unless you reset your device to its factory default settings.
NOTE: Your device has the ability to maintain a constant Internet connection through Wi-Fi or data networks (GPRS, EDGE, 3G, 4G, or HSPA). However, Wi-Fi connection has priority over mobile network connection if both are available.
To check the current Wi-Fi network connection
From the status bar:
When your device is connected to a wireless network, the Wi-Fi icon
in the status bar indicates the signal strength (number of bands that light up). If Wireless & networks→ Wi-Fi settings→ Network
notification is enabled, the 
icon appears in the status bar as the device discovers an accessible Wi-Fi network within range.
From the Wi-Fi network:
1Touch the Home button 
→ Menu button 
→ Settings→ Wireless & networks→ Wi-Fi settings.
2Touch the Wi-Fi network that the device is currently connected to (labeled Connected). A window opens displaying the Wi-Fi network’s name, status, security info, signal strength, link speed, and IP address.
NOTE: If you want to disconnect the Wi-Fi network from your device, touch Forget on this window. You will need to configure the Wi-Fi settings again if you want to restore connection to this wireless network.
