WIFI disabled - Greyed out since iOS 7 update on iphone 4s

hi guys ihave no wifi on my iphone s4 after dowenload ios 7.4 what should ido now please?????????????

There is no mode to solve the problem ! I have the same problem !!

I have tried all. Aplle after many days ... says me to change iphone paying 211 Euros .

Someone solve the problem perforing REFLOW of the chip.

I'm nont happy od apple ... because they know that it's your problem but they doesn't want announce it !!!

SHAME APPLE !

After weeks without WiFi, calling apple, topping up data allowance at own expense, rebooting resetting etc etc. Decided to go out and buy a HTC rather than give apple any money for a replacement. But just before decided to try heating the phone up on the basis of nothing to lose.

Heated with a hair dryer until temperature warning came on screen.

Let it cool down, a soft reset and wifi came back and has been stable for WiFi since. 6 weeks so far.

Had to do same after last IOS update. But came back fine.

Who says its a hard wear problem??.

Why is it that Apple have no interest in helping I have a iPhone 4S and since updating to ISO 7.0.4 I have no wifi at all told me it's a hardware issue and I will be charged for the repair as it's just over a yr old so I've got a 24 month contract so 12 months with a phone that is not working right I have read loads of other people that have the same problem so how can they put it down to the phone and when asked where to take it was told to google it not happy at all apple u need to sort it out never again am I buying anything for yourselfs again DISTGUSTED would be an understatement

iPhone 4S, iOS 7.0.4

So to be clear, is the fault only coming to light on a 4S with iOS7.0X?

I am running iOS7.0 on a 4S and it is fine. I have a friend on iOS7.01 on a 4S and she has greyed out WiFI.

Have been asked to cough up £166 to get my Iphone 4s replaced over this issue! Can't tell you how annoyed I am!!!😠 I won't do it and as my business contract is coming up for renewal shortly I am going to change to a different platform (Android)

Product sold is unfit for purpose and a product recall should of been instigated! The car manufacturers do it why can't Apple. The chip cannot cope with the extra work this new iOS is asking of it, Apple should hold your hands up!.... My perfectly good phone has been rendered useless! I can't even restore back to the old iOS ...I paid a massive premium for this product over competitors products, Apple your attitude is a disgrace. Another customer lost...along with all the other potentential customers who read this and the other poor souls I'll be venting my anger on!😠

It actually started with ios 6.1.3 and Apple never corrected it and now that ios 7 is bigger and more powerful it is happening to more phones after the upgrade process.

The hairdryer solution worked for me as well!! About 4 minutes and it was too hot to hold. Then when it cooled down WiFi was accessible again!! Has been ok now for 48 hours!

I have the latest version of ios7 for the 4s. I can turn on wifi on my phone but it cannot connect, its my house connection and is working but Iphone will not connect. It only broke at 9pm today GMT. What do i do with this?

There is a solution somewhere on here. Turn on siane mode and reset the network settings I believe.

Sorry, that should be airplane mode, not insaine....even though most here are going insane due to our wifi.

I can't edit the post because on the flash on the page. Why would a manufacturer use flash on their site when their own products don't support it?!

Wifi greyed out over here too...

After putting in the freezer and dont working I take the iphone to the apple store and they said some seal is wet and warranty is not worthing... don't put it on the freezer.

My health is worth more than this crap

I thought I had fixed my problem by blow dryer then cool it off

Now it's back to no wifi I grabed this phone and I busted on the wall and I went to best buy and bought samsung galaxy and it does rock.

Good buy apple

No that is wrong. The Apple official fix is ensure Airplane Mode is OFF - then reset network settings.

Follow these steps to resolve the issue:

1. Restart your iOS device.
2. Make sure that airplane mode is off by tapping Settings > Airplane Mode.
3. Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
   This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
4. Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.

Tried this for first, it doesn't work.

Overheating due to IOS7 caused a wifi chip hardware damage, it must be repaired, no way to turn back via software.
