2.2.5 How do I know whether my phone is using its mobile data
connection or a Wi-Fi connection to access the Internet?
The Wi-Fi connection is always used first whenever it is successfully set up. If
displayed in the upper right corner of the screen, that means you are using a Wi-Fi connection
to access the Internet.

2.2.6 I cannot connect to a Wi-Fi hotspot. Why?

 The password you entered is incorrect. Note that the password is case-sensitive.
 The Wi-Fi reception is poor.
2.2.7 My phone's Wi-Fi connection automatically disconnects after
the screen times out. What can I do?
Change the Wi-Fi sleep policy as follows:
Touch Settings > Wireless & networks > Wi-Fi. Then touch Advanced settings > Keep
Wi-Fi on during sleep, and select Always.
Note: By default, Always is selected for Keep Wi-Fi on during sleep. If the settings are
modified, your phone disconnects from the Wi-Fi network when its screen turns off. The
following describes the three options of Keep Wi-Fi on during sleep:
Always: Never disconnect a Wi-Fi connection.
Only when plugged in: The Wi-Fi connection never disconnects when your phone is charging.
If your phone is not charging, it disconnects a Wi-Fi connection when it has been idle for 3
minutes.
Never (increase data usage): The Wi-Fi connection disconnects when your phone has been
idle for 3 minutes.
