HT4628 wi-fi is off and will not turn on

I need help. For some reason my Macbook air has the Wi-Fi off and it will not let me turn it back on. Any ideas?

Might be corrupted Safari preferences.
Open a Finder window. From the Finder menu bar click Go > Go to Folder
Type or copy paste the following:
~/Library/Preferences/com.apple.Safari.plist
Click Go the move the com.apple.Safari.plist file to the Trash.
Quit and relaunch Safari then try switching extensions on.
If that didn't help, type or copy paste the following:
~/Library/Caches/com.apple.Safari/Cache.db
Click Go then move the Cache.db file to the Trash.
Quit and relaunch Safari and try extensions again.

  • The iPhone I got yesterday turned off and will not turn back on.

    The iPhone I got yesterday turned off and will not turn back on.

    Is it charged? If so try a reset by pressing and holding the sleep/wake button and the home button for 20 seconds (maybe longer) until the Apple logo appears, ignore the red slider.  Then turn back on. You won't lose any data doing the reset.  If it's not charged, charge it via a wall socket for a least 30 minutes then try the reset again.

    My iPhone4s turned itself off and will not turn back on unless it is charged at all times. I need help and answers please.

    And we would need more info. "will not turn back on unless it is charged at all times." is pretty obvious: the phone will obviously not turn on unless it is charged.
    Describe your problem clearly.

  • My iPhone has switched off and will not turn back on

    mmy iPhone 5c was working perfectly fine this morning whilst I have been in work. But when I left work and checked my phone in my pocket it had switched itself off and will not turn itself back on. I have tried to plug into charger but still not turning on

    Hi Kate,
    It must be very frustrating to be unable to use your iPhone since it won't even power on. Let's see if we can get things back up and running.
    I would suggest that you troubleshoot using the steps in this article - 
    If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support
    Start with the section titled If your device still won't turn on or start up.
    Thanks for using Apple Support Communities.
    Sincerely,
    Brett L

    Charge with the mains charger for 15 minutes, then disconnect and hold HOME and SLEEP until an Apple logo appears (about 10 seconds).

  • HT4623 My iPhone 4 shut off and will not turn on.  My home button does not work.  Any suggestions?

    My iPhone 4 worked fine last night.  When I woke up this morning, it had shut off and will not turn back on.  I looked up the HOME+SLEEP key solutions, but my home button does not work.  Any suggestions?

    Try a reset: Hold down the home button along with the sleep/wake button until you see the apple, then let go.

  • HT4061 My 4s has turned off and will not turn on I have had in the OTTER CASE

    My 4s has turned off and will not turn on I have had in the OTTER CASE , What can I do to turn it back on

    Do as it says and restore your phone at this point there is no data on your phone.  If you have a backup of your phone you can restore to that backup.

  • HT4993 My iPhone 4s has tured off and will not turn back on I have only had it a week it has been in the Otter box case the entire time

    My iPhone 4s has tured off and will not turn back on I have only had it a week it has been in the Otter box case the entire time. What do I do to get my phone back on??????

    You can try to press the home button and power button and hold them for around 15-20 seconds. This will perform a soft reset similar to pulling the battery. If that doesn't help you may need to restore it.

  • I have an iphone and i was sending a multimedia message and all of a sudden the phone turned off and will not turn on.We have been charging it for almost half an hour or more and it still hasnt turned on. How do we fix it?

    Wine, were you charging over the USB Connection or AC Power?  We've found in our organization that at times not enough power is generated over USB to recharge it in situations like this...I quote from the email of a fellow technician that i just received today...
    I’ve had a couple of users up here bring their iPhones to me so dead that the phone was unresponsive, no matter what we did. One thing that many people do not realize is that the iPhone (iOS devices in general) have power management in them. The power management appears to be set up so that the device will not power on at all until the battery is at a certain minimum level. If the user will plug the device into the power adapter, not a USB port on a computer (laptops especially), and leave it for about an hour, maybe longer, the device will come back to life.
    The reason I say they have to use the power adapter is because the USB port is not high enough power to bring the charge up fast enough for the battery to come back out of “hibernation”. 
    Each time I have had the users do the power adapter plug in, and leave it for a couple of hours, the devices have come back to life
    Hope this helps

  • HT1414 my phone shut off and will not turn back on whats with it?

    my phone shut off and will not turn back on

    Try resetting the device by pressing and holding the home and power buttons for 15-20 seconds until the white Apple logo appears.
    If that does not work, plug it into a wall outlet for about 20 minutes then try a reset.
    If it still will not turn on, take it to Apple.

  • My iPhone was 100% charged. Mysteriously shut off and will not turn back on. Help!!!

    My 1 week old iPhone 4s was charged 100%.  Worked perfectly one minute, the next it had shut itself off and will not turn back on.  I tried putting it on the charger with no change. I hit the power button on top, nothing.  I've tried everything is it just dead?

    Try leaving it plugged in for at least 10 minutes. Then try to do a hard reset of the device: Hold the Power button and the home button until you see the Apple Logo... may hold for at least 10 seconds if you don't see the Apple Logo popup.
    If that doesn't work force recovery mode.
    Press and hold the home button and connect the phone to your computer with iTunes open.
    iTunes should see the phone in recovery mode and allow you to restore it.
    If it still does not work, the phone may need service at this point. Call Apple Care or setup an Genius Bar appointment at a Apple Retail Store.
