The main culprit here is the email widget. As someone advised me before, configure the email widget so it does less frequent checks. The rest of the widget can be set to "offline" mode from the Option menu.

I set my email widget to synchronize every 1 hour, tested it and noticed the wi-fi will remain disconnect. 1 hour later it connects to wi-fi, download email, and disconnect by itself.
