One possibility is that your solderjoint/s of the wifi ic has lost contact to the logic board (very common after a drop). Often resulting in "greyed out wifi" error. Meaning the wifi option stays white/grey and can not be activated.

Many DIY repair tutorials suggest heating the wifi ic with a heatgun (I do not) hoping the solderjoints make contact again. But if it works , it will be only a temporary fix (thats why ppl say, "no guarante that it will last) because its a matter of time before those contacts become loose again.

The ultimate repair would suggest changing oder at least resoldering (not reflowing)the following Wifi IC.

Most of the time, it sadly is a hardware problem related to the wifi IC.

When did it happen, after updating your phone over the air ? Waterdamage ? dropped ?

You can try to rule out a software problem by restoring your phone. Do not forget to backup your phone.

Never forget it is important to know the history of a phone to solve a problem

I think it drop, I had my 2 kids playing with it. I did ask on apple store, they've told me it will be fix but no assurance on how long it will last, it's the problem existed in iPhone 4 & 4s when updates IOS 6 up... it cause battery to work in full and gets hot easily.
