iPhone loses Wi-Fi signal bars when in the same place
When I'm in my on my iPhone 5 at my house connected to Wi-Fi it has about 3-4 bars then all of a sudden the Signal Bars decrease (all the way to one sometimes) when I'm not even moving around. I'm at a good range I'm in the house and I'm about 12 feet away By the way I don't want to sound suspicious but this all started happening when I switched to Time Warner Cable (from AT&T).
It's a Sprint iPhone.
iPhone 5, iOS 6.1.3
