Latest news on this: My friend uses the hair dryer trick since half a year now and found out, that the wifi greyed out, when there are several wifis around.


When he comes home, there is only one wifi. The iPhone connects well.


When he was in a hotel, where he connected more than one wifi and when he returns later to that hotel, the iPhone messes up with the more than one wifis around and greyes out.


Thats what he explainded to me. He always fixes this with the hairdryer.


My grey out issue also occurred in a hotel first, but I can not remember the exact details. Meanwhile I have swapped my iPhone.

My old 4S got the greyed-out wifi syndrome as well as a non-functional bluetooth. Found this thread and tried the HalS method and it worked!


Heat gun for a few minutes, let it cool down. Voila! Both work again. We'll see how long it lasts.


Since so many report that this is a temporary fix, I wonder what could be going on to short that part of the circuit again?
