Wi-Fi on my iPhone hasn't been working?

I have the iPhone 4S and my Wi-Fi hasn't been working since last night. My phone says it connects to the Wi-Fi and as two or three bars. However, nothing will load. Safari, Pandora, Facebook, Instagram, etc. I don't think the problem has to do with the router since my laptop connects perfectly.

How to track someone else's iPhone?

My ex called me the other day and was able to tell me my exact location from the phone call. He lives in another state and has never had access to my iPhone 4S. I changed all my passwords prior to this because he's done this type of thing before. Every time I change my FB password he finds a way to hack back in. I'd like to know HOW exactly he's doing this.
