My wifi on my iPhone 4 S will not turn on

The wifi switch on my iPhone 4S will not turn on. How do I fix this?

Reset, hold both home and power buttons until the iPhone begins to restart. Usually takes about 10 seconds of holding both buttons.

    If none of the tricks like reboot (hold both the power and home buttons until the apple logo appears) do not help, take the iPhone back to an Apple store genius bar and have them test the WiFi module.  You can also connect via USB to a computer running iTunes and update that way.

  • HT201263 iphone went dark, will not turn back on.   it died at end of a call. plenty of battery power.  holding the power and memory key for any amount of time does not solve anything?

    iphone went dark. will not turn on. died at end of a call.  tried the power/home holding option.. no good.  had plenty of power.  when plugged into computer
    nothing changes... its not acknowledged by computer, iphone doesnt charge.. etc... appears completely dead

    If a reset didn't work & you're sure the battery is charged, make an appointment at an Apple store.

  • Iphone 6 plus will not turn on

    I updated iPhone 6 plus to current IOS and then restored using the backup from the prior phone (4s).  The phone will not turn on now.  Any ideas?

    Try resetting:
    Hold both the home and power buttons at the same time until the Apple boot logo appears. No data will be lost.
    Should take no more than 20 seconds of holding the buttons.

    Please clarify what state the phone is in. You could not have done any of the things you mention if the phone will not power on at all.

  • My iPhone 4 16GB will not turn on

    I have had my iPhone 4 for approximately 1 year and a half. I've had no other issues with it until now, my initial thoughts is that the iPhone's battery may need replacing.
    The issue:
    My iPhone turned it's self off yesterday, on the initial reboot it came up with the 'iOS6 installation' and prompted me to connect the device to iTunes. However within 20 seconds of this displaying, the iPhone turned it's self off again. So I left it on charge overnight and once again this morning I tried to turn it back on however this time the device just shows the Apple logo on start up and then turns off and repeats the same process.
    What I have tried so far is the home button and sleep/wake button method of restarting the phone. It does exactly the same, the apple logo appears then turns its self off.
    So if you can offer any more advice on how to fix this please let me know.

    Try recovery mode:
    Leave the USB cable connected to your computer, but NOT your phone, iTunes running, press & hold the home button while connecting the USB cable to your dock connector, continue holding the home button until you see “Connect to iTunes” on the screen. You may now release the home button. iTunes should now display that it has detected your phone in recovery mode, if not quit and reopen iTunes. If you still dont see the recovery message repeat these steps again. iTunes will give you the option to restore from a backup or set up as new.

  • IPhone 4S light will not turn off.

    I Have reset phone and light remains on?

    I had the same problem on my iphone 4 having the light on , changing intensity on its own, with the phone on or off. I noticed that by applying pressure on the back or the metallic sides of the phone, the light would flicker or change intensity and even switch off for brief instants.
    I took it to a phone store (not apple) and they changed the motherboard returning me a phone with the light off. Not for long though as it started flickering again after only a week of use. Yesterday, less than 2 months after the repair, the light was steadily on again.
    I took it down to another phone store this morning which I had used before on a galaxy S3, and he fixed it in 2 minutes!.
    Maybe because of a manufacturing defect, the camera lens and attached flash light are not steadily clipsed to the body causing bad contact. By pressing it back into place, the light has now switched off, but for how long? If it reoccurs, he suggested to replace the camera lens which may not be as expensive as a motherboard which wasn't defective in the first place.
    Hope this helps,
    Cheers,
    Albert

  • My iphone will not turn off

    I push the button on my new iPhone but it will not turn off.  Any suggestions?

    It might be a technical fault and I'd reccomend to visit Genius bar or find a repair shop.
    Meanwhile, if you still want to turn off/on your screen as a temporary solution:
    1. Go to settings
    2. General
    3. Accessibility
    4. AssistiveTouch and turn it on (you should find a small square with a circle inside on your screen now)
    5. Tap this small square to open AssistiveTouch menu
    6. Tap Device and then Lock Screen
    You should be able to turn off the screen now.

    Hi connorfromgrinnell,
    Welcome to the Apple Support Communities!
    I know it has to be frustrating wanting to use your iPhone but cannot turn it on. In this situation I would recommend the steps listed in the attached article.
    iPhone: Hardware troubleshooting
    Will not turn on, will not turn on unless connected to power, or unexpected power off
    Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
    Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
    Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
    After at least 30 minutes, if:
    The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
    The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
    Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
    If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
    If the display turns on, go to step 4.
    If the display remains black, go to next step.
    Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
    If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
    Have a great day,
    Joe

    Assuming your iPhone is well charged, place it in recovery mode as described here.  You may have to try this more than once to succeed.
