Is there anyway to fix this without taking it to the apple store?

The network in my iphone 3GS is malfunctioning. It worked 2 days ago but now it wont connect to any access point even though the security is set without password. I tried reset the network settings but my it required password and I've no idea what it is since I never set it how did it appear. Anyone knows how to fix it?
