IPhone 4s WiFi doesn't turn after iOS 7.0.3

Hi all!
I've a trouble with my iPhone 4s, my guarantee is just ended and Apple phone support askes me about € 200.00 without looking my iphone...
I tried to:
- restore my iPhone,
- restore it by DFU (it isn't jailbreaked!)
- reset only network settings as http://support.apple.com/kb/TS1559?viewlocale=en_US&locale=en_US
- reset only network setting with AIRPLANE mode on (as suggested by some users on the forum)
But nothing, the button is grayed and I can't turned the WiFi on...
Tring to find a solution, I find a user that suggest to put the phone in freezer, I tried it and when I turned on my phone the WiFi goes! I can turn it on and it find my WiFi, but after a minute it doesn't goes again...
Any suggest to fix it or it's dead? -.-

After having trying everything out on the web, I found a fix that worked out. The thing to do is to deactivate your phone and then reactivate it. The way to do it is to first power off the phone. Then take out the SIM card. Then power on the phone and make an emergency call for about 5 sec. Turn the power off. Place the SIM card back into the phone. Power on the phone and plug it into the computer and to itune. Itune will then ask for your user name and password. The wifi will be working.
All you have to do then, is reinstall your saved restored file.
That's it !!

  • HT4528 iPhone 4s' wifi doesn't work after upgrading to iOS 7

    My Verizon iPhone 4s will not connect to wifi after upgrading to iOS 7. You would think Apple would have figured this problem out before releasing iOS 7 to the public. Any fixes?

  • Wifi doesn't work after screen replacement

    My husband was gracious enough to replace the screen on my ipad 2. However, now, I can't connect to wifi unless I'm right next to the router.The antenna needs alot of signal to see any network. He verified the antenna isn't broken. Any ideas on how to fix this problem?

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

  • Touch ID doesn't work after ios 7.1.1 update

    Touch id doesn't work after ios 7.1.1 update..
    Why????

    After IOS update, you first have to use passcode.
    Passcode is needed when
    After restarting your iPhone 5s
    When more than 48 hours have elapsed from the last time you unlocked your iPhone 5s
    To enter the Touch ID & Passcode setting

    My IPhone 4S wifi won't turn on. Wifi button is gray. I have tried restart and very briefly the wifi will work. Any ideas??

    My 4s also grayed out the wifi setting a couple of weeks ago.  I called technical support and the guy _insisted_that there is no known problem with phones with respect to IOS 6.  He told me to reset the phone and restore and that would probably solve all my problems.  Really, there is nothing wrong with the phone, he told me.  I had tried just about everything else I had found on-line.  The complete erase and restore did not work.
    Then I went to the Genius Bar and they tried a few things (more resets) and they concluded wifi is not functioning but since it is out of warranty, they want $199 to replace it.   $199 is not the cost of a new phone so obviously there is some concession here but not a complete acceptance of responsiblity. The Genius Bar told me that - in fact - that there is a known firmware problem with the phones and IOS6 that crops up randomly.  Not with a lot of phones, just the unlucky few.  If it is out of warranty, you have to pay.  Fortunately, I had an extended warranty with my credit card so I can get reimbursed.
    My next purchase is going to be an android tablet. I'm going to wean myself away from the Apple orchard.  I want to expand my options for my next phone purchase.

  • Wake up doesn't work After IOS 7 with my Philips clock radio AJ3270D

    Wake up doesn't work After IOS 7 with my Philips clock radio AJ3270D!
    The other function is OK(listen music like an Ipod or charge)
    Can you help me?

    Apple did update their help section on the app. I found this trying to figure out why my Find Friends wasn't working after the update to iOS 7. 
    "Find My Friends is turned on in Background App Refresh (in Settings > General in iOS 7). When Background App Refresh is turned off, Find My Friends can’t use Location Services in the background. If Background App Refresh is turned on, but you quit Find My Friends via the multitasking interface, location updates won’t be sent to your friends until you open the app again."
    Hopefully Apple will update this as it was not this way prior to iOS 7. Killing the app didn't prevent your location from updating in iOS 6 as I constantly killed the apps running in the background and never had this problem till the update. Hope this helps! Just make sure to not kill the app as of now and to tell everyone you follow not to kill their app and locations will continue to refresh. Otherwise it won't update locations till the app is opened again.

  • Iphone 4s will not power on after ios 6.1 install

    iphone 4s will not power on after ios 6.1 install. Help

    This did not help the problem. History of problems that started 3 days ago before 6.1 update:
    Problems started with the phone dropping a call I was on. Then the screen had lines across it, then screen turned solid green.
    Powered off the iphone.
    Happened again 4 hours later. Dropped call then garbed screen. Powered off then back on all seemed okay.
    Applyed 6.1 yesterday in the morning. Phoned died completely last night. Plugged in over night and it came back up this morning.
    Phone is still within  1 year warranty. Should I just have Apple replace the phone (Warranty runs out in 2 weeks)

  • M3800 Developer Edition: wifi doesn't work after sleep

    I have an M3800 Developer Edition (2015 model). Ubuntu is factory-installed 14.04, with hardware enablement stack installed. Recently (past 1-2 weeks) wifi doesn't work after sleep (lid closed or open doesn't matter), and only rebooting gets in back. Tried rmmod and modprobe with no success. Has anyone else seen this, and/or are you aware of any open bug(s) for this?

  • Why the wifi doesn't work after the upgrade to iOS 5?

    The problem is that after the upgrade to iOS 5 the wifi doesn't work. I mean, iPad is connected to the wifi but not to the internet and also the connection on the other device doesn't work. So I had to turn off the router and then turn it on.

    Try a hard reset first to see if that does any good.  To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.
    If no luck with that, you'll need to manually connect your iPod to your iTUnes library in recovery mode using the instructions in the Apple support document below. Doing so will allow you to bypass the passcode and restore the iPod.
