Wi-Fi suddenly won't work on iphone4?

I've had this unserviced iphone 4 for about 5 or 6 months now and for the past few weeks it's connection to my house's Wi-Fi will cut out half way across the house. I'm usually able to get strong Wi-Fi even from the very back of the house, but as of late I get no connection. My iphone is the only device that does this, everything else like my laptop and tablet get Wi-Fi in the back too. Any idea what's going on and how I could fix it? (I've already tried forgetting the network and reconnecting multiple times)

Restart u r phone and make you r settings default

Have you tried it on another Wi-Fi, say at Starbucks or MacDonald's? If no problem, then the problem is in your Wi-Fi, not your phone.
