You can try a lot of things. Replace the Wi-Fi antenna. Try a Hard Reset (home button + Power Button for 10 Sec). Sometime restoring the phone works. The iPhone 4 antenna isn't really powerful, sometimes you don't get any signal only because your hand blocks it, maybe you put something that block the signal inside the phone.
