wifi greyed out after update to ios7

Hey, I have the solution, and it's insane. But it works.

This video gives the instructions:

Basically, you overheat the phone with a hair dryer until it says it's too hot. It might take 5 minutes. Then put it in the fridge for 10. And wifi is back.

I just did it tonight. It worked. From comments on the video, it looks like it's a permanent fix.

I don't believe that iOS7 killed the wifi chip, I believe there is a deep bug on the software/hardware interface level that even exists on the diagnostic level. This overheating tricks that bug and allows the OS to see the chip as "healthy."

That's my only (layman) explanation. If the problem was truly hardware based, this solution could not work.

Just try it and if it works, pass it along. The guy who made the video deserves an award.

Took my 4s to apple yesterday to be told that this was a hardware problem and since my phone is out of warranty the only thing that can be done is a replacement at £159. The lying little ***** at apple also tryed to tell me that he had hardly seen any phones with the wifi greyed out, I work 40hrs a week in apple and I've hardly seen this he said. So I now own a brick that can only make phone calls with, unless I'm in the car because the Bluetooth don't work anymore either. Apple I need a phone that works 24 hours a day, 7 days a week so a windows phone it is for me I think as you don't care two f**ks about your customers.

I have the same problem wifi greyed out since update, spent hours on apple chat doing all sorts of resets but nothing works, in the end he said to see if it comes on later after Leaving phone off for a couple of hours and that was just to get rig of me, so I went back on this morning only for them to end the chat. Well thankyou very much apple

Chrissie, I did the same thing, is to empty the battery, and switch after 3 hours, but it does not work.

Can you explain how you process in detail please?

Thank you in advance

Do not advise people to damage their iPhone with heat or cold, as it will void the warranty if that method of putting heat on the wifi card is used.

Everyone your wifi card has changed it's temperature, it's a hardware problem that tech support can't fix for you.

You will need to take your iPhones into an apple store.

These are people whose phones are already out of warranty, ergo the reason Apple won't help them.

Stop trying to be a hero Apple_Hero. ;-)

I'm patiently waiting for the deluge of people posting, "omg, the hair dryer worked!" Because it does.

And to point out the irony, Apple advised/forced people to damage their phones with their OS upgrade.

...kind of works. I did it as described above. Once the phone cooled, sure enough - Wifi was able to be toggled and was already 'on/green'. However - it couldn't find any networks to connect to. So I restarted the phone and when it rebooted, Wifi was grayed out again. Argh!

Will try again in a little while but something is very funky in Denmark.

Hi azizeoo I am not sure what you are asking me

Hi Chrissie,

You have the wifi greyed bug and you fixed it, so how you did?

In details please

I know the bug is frustrating right? I had the same problem and when I contacted apple they were in denial for a moment, up until I proved it was not a rumour and that it is a known software issue, which they also say is a hardware issue, they are getting loads of money just from that.

Anyways the solution was:

Blow dry your phone mostly at the top (chip) and wait till your phone tells you the temperature is too hot and you need to cool it down. Then when it is back to normal it will either be connected to wifi or not. but if it is not connected to wifi restart your phone and you'll be good, I know it sounds funny, but just try it, I'm probably saving your a minimum $200, for a replacement.

Post what happened...

No my phone is not fixed I still have the same problem, Apple did not want to know

UPDATE:

I tried it again, same deal - heat until the overheat warning comes on, put it outside (where it;s 30*) for 10 minutes and check. The Wifi was NOT enabled, still grayed out. So I decided to restart the pnone. When it came back up, Wifi was enabled and asking me for the password to my secured home router.

It has been functioning/on for 1/2 hour to this point. Fingers crossed that it stays on...not sure I'll be downloading ANY Apple software updates though....

Many thanks to poster Trent Baur for the youtube link...watch that and give it a try!

ps - Apple ***** for putting us through this and having the potential 'fix' come from a youtube video. I feel so important.

The one additional thing I noticed after doing the blow-dry-iphone trick on the iPhone 4s is that, although I could toggle the wifi, it wasn't accepting the password for the network. So I went into the Airport Utility and essentially "changed" the password to what I'm pretty sure it was all along. And then the iPhone could reconnect. And it's been perfect since.

It's odd because my Macbook continued to connect to the network both before and after I "changed" the wifi password, confirming that it was the same password. But I think I did need to re-enter it on my iPhone 5.

The whole thing is screwy.
