    Default Can't turn on wifi

    Today I went to turn on my wifi when I was out and found that it was grayed out and would not let me

    It was fine yesterday.

    I have looked online and tried rebooting phone, resetting network settings, resetting mobile data, turning on/off airplane mode etc etc

    Now this is a new handset that I had replaced last week as my other 4s had problems. So I have done a phone restore before the problem today

    Try switching to airplane mode,

    power off device

    Then power back on and switch airplane mode to off.


    Then see if WiFi is accessible

    Try a software restore via iTunes.

    When you say you did a restore, do you mean from the backup you made with your old phone? If so, and that one had issues, that could be the issue.

    "my other 4s had problems. So I have done a phone restore before the problem today"

    Think this is what we are confused about.

    If you did a restore as the other 4s had issues, and restored from a back up, this could be the issue.

    Have you tried not restoring from a back up and just setup as new iPhone and see if it works?

    Can you take a screen shot of your Wi-Fi settings and post it here, please? Just simultaneously press the home and power button briefly. You will hear the camera's shutter and the screenshot will be in your camera roll.

    It won't let me upload the pic to the post.

    Also as I have said, my old iPhone did not have wifi issues, so restoring from backup would not be the problem

    Okay. Well, I agree with John's advice. Connect your device to iTunes and select to restore. When complete, set it up "as new". The device should detect nearby Wi-Fi networks and prompt you to select one to join. Select yours. If it connects, great. You can either continue setting up your device (recommended) or restore from a previous backup. If restoring as new does not fix the connection problem and you're certain that your Wi-Fi router is functioning correctly then make an appointment with a nearby Apple Store to have a genius look at it and possible exchange it.

    Which worked? Completely restoring it or repeatedly resetting the network settings?

    Try resetting the network settings and rebooting. Restoring, especially as new, should be a last resort.

    I am having the same exact problem with an iPhone 4s. I did everything recommended in this thread, nothing works. I called Apple support and they had me Backup and restore the phone, reload ios 7, and it still doesn't work. They said its a wifi hardware issue and since the phone is out of warranty it would cost $199 to replace. The phone is insured, but the deductible on that is $179, and it restarts the 2 year contract when you use the insurance. So, any other suggestions before I consider spending $199 to fix this issue.

    Getting an insurance replacement device is not something that should start a new contract at all...

    Hello all,

    I am new to this forum. I have been having this grayed out wifi issue for about two months now. It has been grayed out for two months! Not one day did it work...I have tried everything but restoring the entire settings on the phone, which I do not want to have to do. I also have tried everything on this forum and it did not work. I have the 4S as well. Please someone any more suggestions? This really is a struggle with money problems and using all my data!!! Thank you.


    I uploaded a snap shot of what it looks like !

    Don't buy any Apple products - none represent reasonable value for money.
    And if you must buy one, don't ever update/upgrade software because Apple do program their IOS to kill off old devices batch by batch - this explains why some people experience the No WIFI problem while the rest seem to be okay. And the fact is Apple will never allow you to downgrade IOS says it all.
    For the unlucky one who can't fix their problem by resetting and all other software tricks, try FREEZING because Apple program their phone to shut off the Wifi once the Wifi chip is a little hot, and try Hair Dryer blowing if the freezing only return you so much much time before you need to refreeze again.
    Why hair drying ? Because WIFI chips in certain batches are not printed/soldered properly (defective) and therefore when the new IOS runs, there is a bottleneck of current unable to pass through smoothly, and causing the chip to overheat as a result. Apply heat to the chip area (on the other side of the camera, just below the headphone jack hole) will help to somewhat to allow more flow to the demanding IOS 6 especially IOS 7 (which is designed with lots bullsh*t running in the background - that's what eat up your battery too).
    Unless Apple is willing to change IOS and make it compatible with older phones, the only solution is to downgrade IOS back to IOS 5 which they refuse ... meaning they want you to keep buying new phones.
    If you want to use Apple products, be ready to keep buying new gear or your best bet is NEVER update software.
    I welcome Apple to to tell me this is not the case.
