My iPhone's WiFi was working great on iOS 6 when it first came out, no problems whatsoever, until last week it failed over night without me knowing. The WiFi option was still available but unable to connect to my home network and when I rebooted the phone, the WiFI was greyed out. It has not been working since.


I waited for iOS 6.0.1 to come out as I understood that this was supposed to fix the problem many users with iOS 6 have been facing with WiFi connections, but this has not worked. I do not understand why it has failed. I bought this 4S in February and have never dropped it and it has always been in a case. The WiFi was working great before I went to bed and the next morning it was no longer working.


I have reseted the network settings, restored the phone and even tried using the phone as new and this has still not fixed the problem.

    The WiFi radia in your phone has physically failed. Updating won't fix that. Make an appointment at the genius bar. The phone will most likely have to be replaced.

    then its going to be hardware issue if you have restored the phone as NEW.

    Dear I have same problem my wifi was ok when i bought IPhone 4s Factory Unloked, at that time the software was ios5 as soon as i update its software to IOS 6 the wifi grayed out and bluetooth is also not working. I buy this phone from Pakistan and here their is no company outlet  of Apple, dont know what to do...even ios 6.0.1 did'nt resolve the issue. I have done network reset, factory reset and have refresh the software many time.

  • KiltedTim Level 9 Level 9

    Since the iPhone is not available from any legitimate source in Pakistan, there is a strong likelyhood that the phone was jailbroken or hacked at some point and the hack permanently damaged it.


    If it was not, you'll have to return it to the country of origin for service.

    I had the same problem when I updated my iPhone 4S to IOS6 my wifi greyed out and bluetootht didn't work anymore.

    I turned my iPhone in and 4 weeks later I got a new one with IOS5 and I didn't updated it, still waiting for IOS6.1.

    I just got an answer from someone by Apple who said that IOS6.1 is availlable since yesterday but when I look for updates on my iPhone he only finds IOS6 so I still won't update my iPhone.


    You have to return your iPhone to Apple because this one won't do anything anymore and they will return you a new one. Suc6

    I have somewhat got the same issue too.
    My iPhone 4S has a wifi grey out issue. Full resetting or iTunes Restore method didn't work.


    I tried searching about the issue. Many other apple users have been having the same issue, for quite a while.

    Some of them suggested putting the iPhone in freezer.

    I tried putting my iPhone in freezer for about 15 minutes. That solved the wifi grey out issue.
    But not completely.

    Now, my wifi is detecting the network but gives the error 'Unable to connect to the network"


    I wonder if the wifi module needs to be replaced?

  • pilot1226 Level 1 Level 1

    I have been having this same issue shortly after upgrading to iOS 6 a few weeks ago. Since my update, my wifi doesn't seem to detect any SSIDs, and if I do connect I usually only stay connected for a few minutes before I notice the 3G logo again.


    I can confirm that sticking it in the freezer for 15 minutes seems to work. This makes me think that this is a heat issue. Perhaps iOS 6 is causing some type of error in terms of temperature monitoring and the wifi is disabling itself to save it from a heat failure.


    Upgrading to iOS 6.0.1 did not do anything to the problem.

  • luc.vandevyver Level 1 Level 1

    Same story : wifi worked well on my 4S, prior to IOS 6 update.

    Then, after some days, it greyed out.

    I doubt in this case it is an hardware issue.


    6.0.1 did not solve this problem.



    Using 3G instead of wifi costs a lot of money to a lot of people.



  • cmmcgregor1 Level 1 Level 1

    Recently had this problem too! The guy in the apple store informed me that this would be solved with the next iOS which is due out in about 6 months. But offered me a new phone as I said waiting 6 months was unacceptable, as i use the phone as a personal hotspot for my home internet at the moment.


    More than happy to replace it though!

  • -anders- Level 1 Level 1

    Wi-Fi on my iPhone 4s has not worked since iOS 6, and no change with 6.0.1. Usually the WiFi control is greyed out and when it is visible it can either not find any networks or it stays connected for only a brief moment before failing again. Never had a problem with iOS 5. I also have an iPod and an iPad, as well as several computers on my W-LAN and no problems with any of those, so please don't tell me to reboot or update my router ....


    I've waited patiently for an update but it's now getting to be a major problem, I really need Wi-Fi for some apps, data on my iPhone is getting old since I can't sync over Wi-Fi.


    I've gone through all the suggested tips and trix, resets and restores, and had a long phone conversation with my phone operator's support. I'm a bit worried now as my warranty is about to expire, and who knows what happens with that if/when Apple comes back in a month or two and says I need new hardware. So, I'm off to the store to see if I can get a new phone, or at least some kind of commitment to honour the warranty even if it has expired if Apple later on says they can't solve this with just another software update.

  • accay Level 1 Level 1

    I have been having this same issue shortly after upgrading to iOS 6... and apple dont fixed with 6.0.1!

    Where is Steve Jobs? Apple in the sinking now.



  • luc.vandevyver Level 1 Level 1

    Some extra information :

    after the upgrade to 6.0.1 and the reboot, I got WIFI working ...

    for a few hours.


    Another reboot, WIFI worked again, for a few minutes.


    Thereafter : greyed out.



    I have the impression that bluetooth is infected to.

    My carkit does not always get connected anymore.


    Again Apple : please fix.

    In Europe, international travelers need WIFI ! Roaming on 3G is VERY expensive.


    Thanks for the focus


  • KiltedTim Level 9 Level 9

    Apple is not here. This is a user to user forum.



    Try basic troubleshooting.



    Restore as new (do NOT restore your backup).

    Have you done these things?

  • -anders- Level 1 Level 1

    People have tried "basic troubleshooting" and much more for a long time now.

    I don't believe this is about some simple user error or configuration issue.


    I just got the call from the service guys, I'm getting a new phone.

    I hope it does Wi-Fi.
