IOS 7 on iPhone 4S WiFi and Bluetooth greyed out.  Help!

I upgraded to iOS 7 last night.  WiFi and bluetooth were working fine.  When I woke up today, the WiFi toggle in settings was greyed out and the bluetooth toggle was missing and kept showing the "waiting wheel".  Help!!!!!

All done now - the issue is with the WiFi chip - and when you update IOS it checks all components out to see if they are working correctly, then shuts them down if they are not.
It is a hardware failure, and is pretty common with iphone 4S.... If your phone is over 12 months (and you didn't take out extended warranty) you have the pleasure of paying Apple £139 for a 'remanufactured' phone with 3 months warranty.
Nothing like my expectation for a premium product (with a premium price tag) - its a component durability issue, nothing to do with the user, an Apple component fault. However forget it if you think it is Apple's problem, if it is out of warranty, they aren't interested.My love affair with Apple products is over, google products here I come...
Rant over....

  • IPad wifi and Bluetooth greyed out after iOS5 update

    After updating to iOS5 on my iPad my WiFi and Bluetooth were greyed out like the update has caused a hardware failure on the radio side.  My SIM and 3G still work (not that I use it) but I can not even choose wifi or bluetooth in settings app as they are greyed out.
    In Wifi it says "No Wi-Fi" and Bluetooth it says "Unavailable"
    I wasn't using it a lot so just forgot about it for a while as it sat gathering dust being an expensive paperweight thinking that the next software (5.0.1) update would sort it all out.  It doesn't.  I have a 64GB iPad 3G with no wifi and as I am living abroad the 3G is useless to me (though only use the ipad at home on my wirless network anyway, or not as the case is now!!)
    I have restored, factory restored, cleaned installed new software, everything I can think of but still there is no wifi and no bluetooth.
    Has anyone else had this issue?  My (very expensive) iPad is now next to useless!!
    ANY help is VERY much appreciated.

    thank you for fast response and sharing the link but i've tried everything including downgrade but it seems that theres a serious problem with MC497LL model and trying to reach to the support for any updates about it at least trying to inform them

  • IOS 8.1.2 breaks Wifi and Bluetooth on iPhone 4s

    Since I upgraded my iPhone 4s to IOS 8.1.2, i am unable to use wifi or bluetooth.
    My wifi button is greyed out and I cannot turn it on.
    Bluetooth will just display a spinning wheel when i turn it on.
    I have tried resetting network settings twice, multiple re-boots/re-sets. Toggling Airplane mode. Turning off iCloud. All to no avail.
    Just to be clear, this is not an intermittent issue or a slowdown or anything like that.
    IOS 8.1.2 has completely disabled wifi and bluetooth.
    Anyone else having these problems or got a resolution?

    Yes, but first time in the several years to have a problem. Using Outlook on Mac with MS Exchange Server. I have Exchange set up on both iPhone and iPad. Talked to IT and they are making sure MS Exchange Server is fully updated tonight.

  • IPhone original Wifi and Bluetooth deactivated?

    Ok, so I bought a new 3G and my original iPhone was deactivated, but still worked in every other way besides 'phone', so I gave it to my girlfriend to use as just an iPod Touch right now (she's going to get it activated in about a week with AT&T), but for some reasons in the settings, WiFi and Bluetooth are disabled. Bluetooth isn't that big of a deal, but it'd be nice if she could use WiFi. I'm not sure if the SIM card would have to be activated for this feature to be available or not, but I'm pretty sure it wouldn't have to be. Does anyone know why it would be like this?

    No. It's not.
    I remember right after I completely reset it, it asked me if I wanted to join my WiFi, and I just said no (since I was giving the phone to her), but now that she has it, the option is completely disabled.

  • Iphone 4S - Wifi and bluetooth buttons don't work

    Wifi and bluetooth buttons don't work in my Iphone 4S. I have tried all the suggested possible solutions, but nothing seems to work. Can anybody help?

  • After IOS 8 update I my wifi toggle is greyed out.

    After some research I learned I should have turned off the where's my iPad on iCloud before I updated to IOS 8.  Now I cannot turn it off or do anything that requires the internet.  Yes I have tried to reset via iTunes and the iPad itself but without luck as they both require where's my iPad to be turned off!!!!!  Totally lost without my iPad!!

    Hi Staci ..
    Reset the device:
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
    If that doesn't help, tap Settings > General > Reset > Reset All Settings
    If that doesn't help, tap Settings > General > Reset > Reset Network Settings
    You may have to re enter your Wi-Fi password.
    * No data is lost due to a reset
    If nothing above has helped, try here >  iOS: Troubleshooting Wi-Fi networks and connections
    iTunes is not used for resetting devices. Only syncing and restoring.

    Hello, lustige luka. 
    Thank you for visiting Apple Support Communities. 
    The Personal Hotspot feature using USB  should be as simple as connecting the device to your Mac via the USB cable when Hotspot is enabled.  Here is some more information regarding this feature and an article that will provide some troubleshooting steps if you are experiencing an issue.

  • HT4623 I updated my iphone with IOS 7 and my wifi and bluetooth is not working. How can I go back to IOS 6?

    I have updated my iphone 4s with the last version IOS 7.0.2.
    At the beginning my screen freezing each time I enter numbers or letters (in iphone security code as well as texting in any app)
    Now, my wifi and bluetooth are broken. I have tried to activate them 3 days and nothing.  I am lost. I have no internet in my telephone plan, so, all my apps are not working anymore.
    How can I go back to IOS 6?
    My iphone will be working correctly again???
    Thanks!
    I very appreciatte any urgent answer .

    Downgrading the iOS is not supported at all.

  • HT6154 iOS 7 and iPhone 4S - I lost my WiFi and Bluetooth capabilities last September with the new OS, and I THOUGHT it was actually fixed this morning with the latest release - my WiFi AND Bluetooth actually worked....for about 5 minutes, but no longer

    I thought this latest OS release had fixed my WiFi and Bluetooth problem, but I was excited for only a minute!  I actually was able to connect to my WiFi at home and paired my Bluetooth to my car - but after a few minutes, the Bluetooth automatically turned off and the WiFi no longer worked.  Is there a FIX to this???  I know it's the OS that disabled them and I'm not paying $500 for a new phone when my upgrade is not availbe for another six months!!!!

    My iPhone 4S did once again did  lose it's wifi connection after running perfectly for about 8 weeks.
    I was streaming Pandora Radio via bluetooth connection at the time, ( not sure if that has anything to do with why the wifi dropped out again, but I thought I'd mention it anyway)
    But!.... I was able to get everything up and running perfectly again by simply grabing my girlfriend's hair dyer heated it up again for about 5 - 7 minutes ( the over heated message even appeared this time) then powered it off, warped it in a plastic bag, stuck it back in the freezer for 15 minutes, took it out of the freezer, powered it back on, and Abracadabra it works perfectly again!!!
    Phone has been running perfectly AGAIN for about a week now.
    One strange thing this time after fixing it for a second time is that the the little WiFi symbol no longer shows at the top of the screen, but the wifi connection and everything IS RUNNING PERFECTLY!
    If all I've got to do once in a while, is spend about 20 minutes with a hairdryer and a freezer to keep my iPhone 4S running perfectly.....well I'm as happy as a pig in s*** :-)
    And please no comments about how I have now voided my apple support etc. I never had any to begin with  (it's a 2nd hand phone and  I really  couldn't care less about warranty issues etc etc etc..... The phone works, and that's all that matters to me!

  • Has anyone else downloaded iOS 7 on a 4S and found the WiFi and Bluetooth don't work anymore?

    I'm used to Apple products that "just work", but I'm not seeing it with the installation of iOS 7 on my phone (4S). I installed it earlier today, and the Wi-Fi and Bluetooth worked for about an hour, then just quit working altogether. The WiFi button is grayed out in Settings, and Bluetooth dosen't even display a button (all I get is a throbber that continuously spins). Trying to activate them through the "swipe-up" command center doesn't do the trick, and resetting the network settings also accomplishes nothing. Several reboots later, and I still don't have WiFi and Bluetooth.
    Has anyone else experienced this, and is there a solution? I may just decide to eschew iOS 7 and restore my pph

    After multiple attempts to restore and reboot, I finally decided to take a trip to my local AT & T store. They contacted Apple, and I explained the situation. I ended up moving to the iPhone 5, as my 4S was in the renew period. The 4S is still under warranty, so all I have to do is bring it to an Apple Store, where they will either fix or replace the phone. Looks like one of my kids will be getting a 4S :-)

  • My Air Drop feature is not working. I have an iPhone 5S running iOS 7.0.3, my wifi and blue tooth is on and I am set to "everyone" in control panel. I am not able to see anyone in the AirDrop box to be to share pics or contacts.

    My wifi and Bluetooth is on, in control panel I have "Everyone" on, I cannot see other iOS devices that are using iPhone 5 or 5S. My phone is only a couple of weeks old and was purchased brand new and I am on AT&T. I can not see other devices and other devices can not see me. I checked the manuel and I don't see any other settings other then what I described above in regards to control panel. Anyone have a solution for me? Oh by the way I have rebooted my phone, did a hard reset 3 different times but still not working. I do have an active iClould account.

    I read a previous blog from a Mac user who was having an AirDrop issue. He resolved it by deleting his icloud account and reinstalling it. I figured what will it hurt to try this with my iPhone 5S. Well I am happy to say it worked. I recall recently changing my Apple ID password. This must have affected the Airdrop feature. When I reloaded my IClould account it started working. I don't know why but it's something you can try if all else fails. Hope this helps someone.

  • TS1559 Wifi and bluetooth is not working on iOS 7.0.2

    Its disappointing to see crazy bugs even after a .0.2 release. All the work rounds fail

    I Am IT support for a large Company also using iPhone 4s. I can confirm this issue as employee's start upgrading to iOS7.0.2  Bluetooth and wifi working fine on iOS 6.x as soon as upgrade to 7.0.2 Wifi Toggle greyed out, No wifi MAC address, bluetooth not working.
    Have tried all suggestions on various forums to no avail .
    Even a DFU recovery and set up as a new iPhone failes to fix the issue.
    Have advised users if they have this issue to return the phones to Apple.
    Also discussing with Other IT collegues in company to send out a bulletine asking employees NOT to upgrade to iOS 7 at this stage.
    Whilst my company iPhone upgraded fine, it would appear not all do. I suspect different versions of the WIFI and Bluetooth hardware would be the cause of this issue. This would explaine why some upgrade ok and others do not.
