Wi-Fi isn't connecting?
 

Well, my WiFi for the mogul has been working perfectly fine until a few days ago.

It's almost like it disappeared. Usually when I turn on WiFi, I get a notification instantly. or it connects.

Now, I just see the WiFi sign and no hotspots are popping up.

check your settings
 

Did you check your WiFi connection settings? Did you recently change any of your sounds and notification setting for wifi? Check those..

I also had this problem, WiFi on the phone working fine for 4 months, and suddenly not connecting at all. I just took it to the store and Sprint replaced the phone on the spot.
