    All I know is no one has came up with a solution to fix this problem, apart from this one that has worked on mine and solved the problem. had no option but to try this fix or pay £200 extra for a used replacement from Apple as they state it cannot be fixed.

    OMG, it WORKED!!!!


    Thank you Highonlife!  We were JUST about to head to the apple store and fork out $$ for a phone that was JUST over a year old, but we tried the heat/cooling technique at the link you suggested



    Gee. I would hate to be so cynical to think that this is a software scam.  This should be brought to the attention of thing on my list....

    After resetting everything, many hard shut offs and a hair dryer, I put my iPhone in the freezer!  I was totally surprised that my wifi was already on and found my network!  Thanks Lawrence Finch!

    Same problem as listed.. I tried the blow dryer method, and I got the wifi back for about 5 minutes. The phone auto-shut down and upon reboot, the wifi was greyed out again.. I really believe it's a firmware issue, and although these quick fixes work, they are temporary. My problem began after the latest iOS s/w update 7.0.6.

    Had the same problem (WiFi grayed out, no wi-fi available) all of a sudden today. I tried the network reset - no change.  I was planning to try the Apple suggestion of resetiing iCloud and started by going to Settings - iCoud.  I turned off everything in iCloud, including Find My Phone and when I went back to Settings, I saw that my wi-fi was trying to find a signal.  It found my network and it's working again.


    I have since turned Find My Phone back on and it all works.


    iPhone 4S, out of warantee (of course); hope this helps someone.

    I tried a number of these things to fix the greyed out wifi on my iphone 4s. The freezer thing worked for about 5 mins, but they got heated up and stopped working.


    When I took it to the genius bar (in Vancouver, Canada), they said nothing was wrong with my phone in terms of hardware damage and they could do nothing but suggested I get a new phone.


    I want apple to sort this out with the iPhone 4s. I think there is enough iPhone 4s users that shouldn't have to get a new phone souly because they updated their phones and the updates caused they're wifi to stop working. This is an apple problem. Also, when I've looked through the apple website to contact apple to share these thoughts... there is no where I can email... Seriously need a suggestion box somewhere on the website and don't tell me I have expired applecare so no help there.


    I've only had the device for 16 months (warrenty only good for 12 months). If iPhones aren't build to last they are crappy phones and I'm done with them.

    What a scam. Both my sister and mother are having this issue with their 4s. Of course the apple suggestion is just to replace the phone. Tried the heating method and it worked a treat. This really is bs apple fix your crap!

  • mcguirejw Calculating status...

    I tried something even simpler and faster than the heat treatment and it worked--at least for me.  I have avoided upgrading my iPhone 4S to iOS 7x, and yesterday I found that for no reason the WiFi switch on Settings was greyed out.  I followed a suggestion posted on the first page of this thread from Istanbul and simply reset the network settings.  It worked!  Go to Settings, General, Reset.  Select Reset Network Settings. The phone turns off and then restarts.  WIFi is back again!

    I'm a mac user and fan dating back to the 80's as well as a share holder and honestly Apple should be ashamed of themselves for how they're handling the iPhone 4s wifi and bluetooth greyed out / non functioning problem. As many have concluded the update to iOS 7 has rendered thousands of 4s's virtually useless due to how the update is making the wifi chip (which manages the bluetooth functions) overheat telling the system to shut them down.


    They keep claiming it's a hardware issue--which isn't exactly true. Apparently the software update is making the hardware run hotter than it should. Then the software is shutting down the wifi and in my case the bluetooth functions. Resetting the network configurations didn't work. The freezer remedy only solves the problem for a short time. Until Apple provides some kind of fix voluntarily (as they should to loyal customers) or is forced by a class action lawsuit and subsequent recall (hello, where are the greedy attorneys when you need them. ;) the best fix I could find after 4 months of scouring the web are these videos made by an iPhone 4s customer who had the exact same problem. He even went as far as to secretly video tape his interaction at an Apple store as well as report his experience to the local NBC news affiliate:



    Apple store meeting (identical to the experience I had with Apple):


    This fellow provides a briefer explanation with a disclaimer that it may not be permanent:


    Hope this helps
