taniapena Level 1 Level 1

Hi everyone,

so I updated my iphone 4s to iOS 7.0.6 through itunes and the wifi stopped working. It's grayed out. I've read a lot about this issue around the internet but so far I'm not able to find someone with this problem after installing the latest update.


Is anyone experiencing the same problem? How can I fix this? I've already tried restoring network settings as well as factory reset and nothing worked.

Is there a way I can install a previous version of the iOS, considering it was working before this update?


thank you!

iPhone 4S

    No, you cannot downgrade your iOS.  This is usually a hardware issue, not an iOS issue.  The most common cause is that the heat produced during an update was more than the (defective) wi-fi chip could tolerate.


    iOS: Wi-Fi settings grayed out or dim - Support - Apple

    already tried all that. It still doesn't work.

    Then your options are:

    A) If within warranty, get the device replaced for free via Apple.

    B) If not, then pay the appropriate out-of-warranty fee (for an iPhone 4S = $199 USD + tax) for a replacement.

    C) Request a one-time exception to the OOW fee from Apple, preferably using the script I provided at

    D) Live with the lack of wi-fi on the device.

    E) Seek a third-party repair solution, which will void any future service options for that device from Apple.  Additionally, detailed discussions of such options are prohibited on this forum.

    F) Purchase a replacement device out of pocket, either another Apple product or one from a different manufacturer.

    Thank you for answering.

    However, it's out of warranty, and I don't really understand how a problem with an update provided by apple translates to paying a fee to replace the phone itself. It was working perfectly fine untill I installed the update today.
    You say it's more than the defective wifi chip could tolerate, but it wasn't defective in the first place? otherwise it wouldn't be working, right?
    Anyway, I'll read the link you posted on that problem to learn more about the issue.
    I'm just really baffled by all this. I can understand that a software problem can cause a hardware one, what I don't understand is how a software update from apple is more than what their phones can take.

  • TJBUSMC1973 Level 5 Level 5

    Yes, it was defective in the first place.  Like many other defective pieces of equipment, the defect may not reveal itself until there has been a certain amount of use or stress applied to the device.  Think of 'the straw that broke the camel's back'.


    Use the script I provided to request an exception to the normal out of warranty fee.  The local Apple Store will probably not be able to grant such an exception, so you'll need to call Apple Support, ask for a supervisor, and then present your case.

    This is exactly the same thing that happened to my daughter's iPhone 4S. Based on the number of questions and replies, this sounds as if it's a design flaw in either the software or the hardware. It does not sound like a "defect".


    I agree that responsibility for this fix should not be on the user

  • TJBUSMC1973 Level 5 Level 5

    It's not a design flaw in either the software or the hardware.  It's a defect in a very small percentage of iPhones, and slightly more common in the iPhone 4S.


    This forum only represents a very, very small percentage of Apple users.  There are millions of iPhone 4S units out in the world.  The vast majority experience no issues.


    If you are within warranty, the fix is free.  If you are not within warranty, the cost to fix is $199 for an iPhone 4S.

  • Amccorkle Level 1 Level 1

    Then, by your own analysis, a "small percentage of the millions of iPhone 4S units out in the world" would mean there are likely to be hundreds of thousands of units encountering this problem!


    According to the clerk at the Verizon store, folks are coming in every day only to find they need to purchase a new phone.


    This sounds like a recall issue!  And I would suggest that if the retail cost is only $199 per user, the actual cost to Apple would be much less per unit simply to issue a recall notice.


    I will continue to tweet and FB post on this issue.

  • TJBUSMC1973 Level 5 Level 5

    It's not a recall issue.  It's a very small number (in context) of users having the issue.  It doesn't constitute a recall.

    Feel free to post on social media sites about this.  That's not going to change anything.

    Contact Apple support for your options.  If you are out of warranty, politely request an exception.  Ask for a supervisor.

  • taniapena Level 1 Level 1

    Thank you for that link where you explain on how to request an exception, it might be the only option for the (I'm guessing hundreds from what I've seen) users experiencing this problem.


    I tried the blow dryer method and it worked, which means it is a hardware problem. For how long it will work - I have no idea. The thing is, like you said, I had no idea I had a problem with my wifi chip up untill now.


    Do you know if it's possible to change the wifi chip through apple? How much would it cost? Or are they going to tell me to replace the whole phone?


    To the other people with a 4s, if you want to avoid this happening to you, I guess your only option is NOT to update your iphone software. I could never imagine that by doing so, the chip would reveal to be defective, so if you want to have a working wifi, just don't update it and try not to overwhelm your phone lol.


    I've read a lot of people here saying apple should take responsability and not blame it on the user, I agree with that to some extent, but let's be rational about this. If you had no idea you had a defective wifi chip, then yes, there's no one to blame really, and try to ask for an exception. How can you be responsible for something you didn't know was going on? One thing I would like though, would be for apple to acknowledge this is an issue and, I don't know, maybe inform people that this might happen if you update your phone's software? Make it official, just like in medicines where most people won't experience side effects, but a "small" percentage of them will.

    Add another one to this list   . Wonder how many more (that just haven't got around to posting)?

    Did all suggestions that Best Buy reps gave us but no-go. Will be trying to get to an Apple rep this weekend.

    What use is my phone now if I can't make hands-free phone calls while in my car or elsewhere. What good is my phone if I can't use wi-fi either? What's in that Ios 7.0.6 anyways that was never an issue for me in any other software upgrades????

  • F.zauz Level 1 Level 1



    I have the same issue since I update mi iphone 4s, if I reset the network settings, it work´s a couple of hours, but then stop working again. I nerver experience any issue whit my phone until now. My warranty ends, and i live en Mexico, my question is that I be able to use thethe fix is free here, or only apply in the US?



  • nottorydave Level 1 Level 1

    I have the same problem.  My WiFi button is grayed out.  I have reset and restored on iTunes and no change.  I am really frustrated and considering changing to a new phone manufacturer.

    Nothing.  It's not the software; it's a hardware fault.  The heat from the update process caused the issue, not the actual update itself.
