Apple iPhone iOS 6 Issue Wifi Disabeled/ Greyed out

Ever since Apple rolled out the iOS 6 update, user have been troubled with the various issues like battery draining issue, passcode hack problem and few other issues. One of the most common issues most discussed in the forums right now the Wifi Issue, where the WiFi option is disabled and you can turn it on.

One of the solutions people have tried to fix this issues is by resetting network, it unlocks the WiFi option but then presents with another one, the phone is not able to detect any WiFi Networks.

Some users reported on the Apple Discussion Forums that it has something to do with the phone not being able to detect the 2.4GHz network speed but seems to be working fine with modem with 5GHz network WiFi speeds.

The problems has arised only after the iOS 6 update, a device on iOS 5.1.1 is working fine on the same network but the other device on iOS 6.0.1/iOS 6.1.1 is having issues, so it’s clear there is a bug that came up with the iOS 6 update.

Update ( 6.1.2 also did not fix it)

Other known WiFi issues is that the iOS device detects the WiFi Network but doesn’t stay connected for more than few minutes and then has to be connected again.

Apple has admitted there are some issues with this their latest iOS 6 update which they have mentioned in their latest post about the problems with the upadate that are all supposed to be fixed in the in the iOS 6.1.2 update.

Users have also reported that when they called Apple regarding this issues, specially those out of warranty or got their iPhone from a different country, Apple execs told them that they will not help them until they get a 249$ 1year/ 99$ 3month phone technical help plan for a problem caused by the Apple iOS 6 upgrade.

Update March 20, 2013
I had bough my iPhone from the US, unlocked, and had been using it in India, since the warranty was not valid in India and my father was going to the UK to get a award for his social work I gave it to him to get it replaced as US warranty also works in the UK. He switched on the phone in turned on the Airplane Mode in the Plane and when clicked on the WiFi option amazingly the WiFi was Working. I still told him to get it replaced, so a few days later the problem came back and WiFi greyed out again so he got it replaced at the Apple store. Now he has the phone on iOS 6.1.2 and WiFi is working fine in the new one.

Apple’s Official iOS 6.1.3 release notes mention nothing about the WiFi Fix

Vodafone UK – Has also issued a warning it’s users not to update their iPhones to iOS 6.1

We’re aware of an issue caused by Apple iPhone 4s handsets that have been upgraded to iOS 6.1 which impacts performance on 3G.

 Some customers may occasionally experience difficulty in connecting to the network to make or receive calls or texts or to connect to the Internet. Apple is working on a solution to their software issue. These connection problems are intermittent.

 While Apple’s investigations continue, we would recommend that anyone who has not yet installed iOS 6.1 on their iPhone 4s should delay doing so until Apple has confirmed that their problem has been fixed.

Known Fixes for iOS 6 WiFi issues

Official Way

Apple has given some general which are generally fix for any issues you may face, these methods have worked for few permanently, temporarily for more of them, and not worked for most of them.

  • 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.

If that doesn’t work

  • Clean Safari – Clear the cookies and the history of your Safari Browser from the settings

If that doesn’t work

  • Reset the network – Settings > General > Reset > Reset Network Settings, this method usually unlocks the Wifi options but the WiFi doesn’t detect any networks. This is probably related the Router Network speed configuration which is not detecting 2.4GHz, but is working with 5GHz speed.

If that doesn’t work

  • Factory Restore – Connect your device to the computer and restore from your iTunes.

If that doesn’t work

  • Replace it – If you have it under warranty, and living in the same country get it replaced from the Apple store and prefer the one that is on iOS 5.1.1.

If that doesn’t work

Unofficial Way (updated 15Mar2013)

  • Downgrade it to iOS 5.1.1 – This is only possible if you had Jailbroken your iOS device when you were in iOS 5.1.1 and had saved SHSHs blobs, if you don’t know what I am talking about then this step won’t for you

If that doesn’t work

  • Fridge it: Some users posted on the forums that they sealed packed their iPhone, after shutting it down, and kept it in the fridge for some time, like 5 to 10 minutes. Then they brought it out and turned it on and the WiFi was working, this method is also used to fix battery problems.

If that doesn’t work

If that doesn’t work

  • Try to Downgrade it! – An attempt to downgrade the iPhone to iOS 5.1.1 some how fixes the device
    1. Download the iOS 5.1.1 ipsw for your device
    2. Download Redsn0w 0.9.15b3 (Windows / Mac) and extract on your desktop
    3. Connect your iProduct to your PC
    4. Keep Redsn0w and the IPSW file in the same folder
    5. Open Redsnow
    6. Click on Extras (Everything Else)
    7. Click on Restore (Restore to an IPSW)
    8. Select IPSW from the folder you downloaded it in
    9. Follow the steps (put it in DFU Mode)
    10. Let it do it’s thing
    11. It will tell you that downgrade is failed (Since you didn’t have SHSHs Blobs)
    12. Disconnect your iPhone from your PC and restart it and check the WiFi it should work.

    I haven’t been able to try this myself as I have sent it to UK for replacement.

I have an iPhone 4S with the same problem so as soon as it gets fixed for me I will post here at the same moment.

Anyone tried the iOS 6.1.3 update?

    I still do not have a solution. Mine has been out for quite some time. I have tried all solutions. This is insane. The 6.1.3 upgrade has not done anything to assist with the issue. :-(

  2. taeyanguk says:

    still no solution?

    1. Angad Singh says:

      Many say 6.1.3 fixed it… let’s wait for iOS 7…. Personally I don’t support the Hear Dryer or the fridge method though that’s what worked for many…

    Hi all, I've had the same problem with my iPhone 4S running IOS 6.1.2. BUT it is back online with a not greyed out WiFi :-))) history: _I was really frustrated because warranty was over and because of I have bought the iPhone in Orlando USA (I am living in Germany) I had no chance to get it changed in the Apple store. I know warranty is only for 12 months but Apple care told me via phone that I get a refurbished one in an US apple store. Ok, not really an option for me ! Then I tried everything which is posted here. Reset network settings, Backup as new iPhone, jailbreak, try to downgrade, fridge, hairdryer etc… The only thing which worked for me was the fridge :-) After 20 minutes with -16°C i was able to turn on WiFi. The Wifi switch was not greyed out anymore and wifi was connected to my router. Unfortuneately it only worked for 10 to 15 minutes and then wifi lost connection and the switch was again greyed out. __—My Solution— (wifi is working for nearly 2 days now without any interruption !!!! )_I forgot my iPhone on my desk at work. At the next morning I recognized that only 10% Power was left in the battery. Of course it last not the hole day and so when it reached 4% it switched off automatically. When I arrived at home a couple of hours later I´ve plugged it to the charger. When i looked at it again it has some 30% battery power and as a really big surprise I saw the wifi symbol which said connected to a network :-))))_ I couldn´t believe it but it was true !!!! My wifi was working again and it was connected to my home net. I ve tried a lot things since now ( switching to flight mode, switching the phone off etc.) but it is still working 100% and as I said fully stable .__So let your Iphone run fully out of power,maybe wait some extra time and then charge the phone and look what happens !__I really hope that this is not only a coincidence and that my post help you guys to manged this annoying problem !!! Give it a try it really solved my Problem (again: 2 days now and still working :-))__I would be happy to get your feedback !!!__Best regards _Michael_
