iphone 4s wifi option disabled.

Ur right! AC it is then!

Update: problem came back again so we are back to ground zero!

Just found out my wife also has this issue and after reading this thread we're still no nearer to sorting it... My iPhone and sons iPhone are fine so where is the issue

Brother Usman, Thank you very much for your solution.

Hi all,

I was having same issue and tried almost evrything.

Updating iOS 7.0.4 to 7.1 beta and after around 12 hours wifi started working.

updating to iOS 7.1 beta solves wifi issue for me.

Do a hard reset – Press and hold the home button and the power button till the phone shuts down, screen goes blank and then Apple logo reappears.

It is worked in my phone

same problem here since 1 year.

i thought it was shot your iPhone with a hair dryer, the put in freezer like a fish

so it's heat problem then,

mine working just one time i put it at freezer.

but there it goes again

I have one iphone 4s and westerday its stop to work and i have the ios 9.1, what i need to do?

how do i disable
