A common problem in the iPhone 4S, sometimes the Wi-Fi button will be [|grayed out and unclickable]. This problem seems to be related to thermal shock the problem may be temporarily fixed by simply putting the phone in the refrigerator for 15 minutes, or under a lamp for 30 minutes.
If this is the case, then the necessary permanent solution is to reflow the ''Murata SW SS1830010'' Wi-Fi chip on the logic board.
