Wifi and bluetooth not working

Since I loaded IOS 8.1.1 on my 4S iPhone I have lost bluetooth and the WiFi is greyed out so that I can't use it. Other 4S users in our organisation are
having the same problem and I see lots of angry iPhone users on the web ready to ditch Apple and go Microsoft or Android. I've tried the freezer trick and
Apples support suggestions but they are not the solution. The reality is that the upgrade caused this issue and we need an explanation and/or fix
Apple...please fix it or you are going to lose a once very loyal customer that’s been standardizing on Apple for its staff ever since your first iPhone.

Hi Truthsay1,
Welcome to the Apple Support Communities!
I understand that it can be frustrating when Wi-Fi is not functioning as you would expect. Please follow the troubleshooting steps located in the attached article for help troubleshooting.

Have a great day,

  • Installed iOS7 update and now wifi and Bluetooth not working

    My daughters 4s has never skipped a beat - perfectly reliable. Just updated iOS7 with update and now both wifi and Bluetooth not working. Wifi is greyed out and when you go into bluetooth the busy twirly symbol is constantly going round. Can someone please help me as I'm pulling my hair out! My other Daughters iphone 4s is fins BUT she has not downloaded latest update - and she won't until this is resolved. If needs be I will take to store and DEMAND for it to be sorted out - either by repair or replacement as it is wholly a seemingly software issue and nothing wrong with the phone.
    Gutted really as I am a huge Apple fan and customer with ipods, phones, iMac & iPads all around. If this is not resolved I fear an Apple drought may begin!

    ..... ty for the link, however this is the first result googling the issue..... of course it did not work....
    it is really unbelivable that plenty 4s devices suffered the wifi troubleshooting just after upgrading to ios7, and finally.... i should burn wifi and bluthoot, and another hardware problems should cause % battery value is disappeared....
    all this in one shot....
    firmaware is not well working or is somebody bombing our devices to force us to switch to newest?

  • No wifi and Bluetooth not working

    My wifi is not working. I'm not allowed to select wifi in settings as it is covered in a gray non selection mode and says "No Wi-Fi". I'm also having trouble with my Bluetooth as it disconnected spontaneously one day and decided never to come back on since. When I go to Settings>General>Bluetooth there is no option to turn the Bluetooth on, instead the small circular loading icon appears where the on/off switch should be located.
    Much help appreciated.

    Try restarting the iPhone.
    If that doesn't do it, take a look at Apple's doc for this -> iOS: Wi-Fi or Bluetooth settings grayed out or dim

  • Why have the ports on the left of my macbook pro and the wifi and bluetooth stopped working?

    Hey All,
    About a week ago the two usb ports on the left of my 17" macbook pro, soundcard, wifi, and bluetooth stopped working. The power port, ethernet, remaining usb on the right are still functional. I've tried repairing the permissions and other software based solutions but to no avail. I'm worried that this might be a motherboard issue but am apprehensive about taking the ol' girl into a genius because it will probably cost more to repair than the remaining value of the system. Anyone have any ideas, can confirm my suspicion?
    Thanks!

    Well I'm using Google Chrome browser on Lion and when I type in that URL nothing happens. Except for the "This webpage is not available" banner.
    So it looks like your website is down and what you are getting on your devices are cache.
    Oh just deleted the www and now I see the page. Yup all the info looks intact. home about us products Q&A and so on.

  • After upgrade to ios5, wifi disabled and bluetooth not working

    After I upgraded my 3gs to ios5, my wifi is permanantly disabled (just says "No Wi-fi" in light gray under settings menu). I also am having problems with my bluetooth. I can see my old connections/devices, but cannot connect to them anymore.
    Any ideas how to resolve this?
    Thanks.

    Have the same issue. I ugraded my iphone 4 to ios5, wifi shows no wifi and bluetooth keep searching. Even my iphone automatically shut down after 1 day. 
    I have reset all the setting, configure my iphone as new iphone, but still the problem remains same.
    Can any one provide help on this?

  • IPhone 6 Wifi and Blutooth not working after update!

    I updated my iPhone 6 this weekend and did not back it up before doing so.  I now notice that my WiFi and Bluetooth are off and not working! I can't turn the back on.  I reset the phone, I even reset all the network settings, but can not turn them on.  I also noticed that I am not getting text an emails as quick.  My iPad Air is fine, but my phone is really screwed up.  Any suggestions?
    Also - I have to say this, what's up with Apple lately? Why so many issues with updates lately? I (and everyone else) pay a lot of money for these devices and the service, how about putting out updates that don't screw everything up for a change.

    Read these articles: [iOS: Troubleshooting Wi-Fi networks and connections - Apple Support] [iOS: Troubleshooting Bluetooth connections - Apple Support]
    And it was unwise to not make a backup prior to updating.  That's contrary to what Apple recommends: [Update the iOS software on your iPhone, iPad, and iPod touch - Apple Support] (Before you update Back up your device to iCloud or iTunes.)
    And what issues with updates are you talking about?  This is your first post on this forum.

  • 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!

  • Thinkpad Edge E330 wifi problem, wifi radio and bluetooth not working

    hello gays,
    I have win 8.1, and recently my Wi-Fi does not work. I tried everything, I remove the driver and installed again and again with no results. I have the pci mini express.
    I install the Lenovo diagnostic tool and here are the results: 
    Can anyone have an idea for a solution?
    Thanks…

    Hi Shlomi1204,
    Welcome to Lenovo Community!
    As per the query we understood that you are facing issue with Wifi on your ThinkPad Edge E330.
    The warning indicates that Wifi is not enabled, and to enable it you have to press FN+F9 simultaneously. When you press this key, a list of wireless features is displayed. You can quickly change the state of each feature on the list.
    Notes: If you want to use this button to enable or disable the wireless features, the following device driversmust be installed on your computer beforehand:
    Power Management driver
    Onscreen Display Utility
    Wireless device drivers
    For detailed information on the wireless features, refer to “Wireless connections” on page 29 from the user guide.
    Hope this helps.
    Best regards,
    Hemanth Kumar

  • I have just updated my iPhone 4 with latest IOS 7 and now wi fi greyed out and Bluetooth not working. Tried reset, restore everything - no use. Its out of warranty too. I refuse to pay for a new phone when clearly this is an apple issue not phone issue.

    Can anyone help? I updated my iPhone 4 with latest iOS 7 and now wi fi is greyed out, Bluetooth won't work and tbh am so angry! Phone now out of warranty so apple won't help without it costing me. Don't want to pay as its an apple problem not phone problem. It worked ok before. Tried everything, even clearing it down. Can't even back it up now unless I connect to a pc!

    I have not had wifi since November when I upgraded to the newest IOS version.  I called the Apple help line and they told me some things to do and I tried them all and they worked for a few hours and then wifi shut off again.  I kept doing what they told me and it worked for a couple more days and then I could never turn it on again.  My blue tooth doesn't work either.  I had to actually increase my data usage with AT&T becuase of this.  When I did that in December I went to the Apple store and was told that it is a hardware issue and since my phone is out of warranty I would have to pay for a new phone because they could not fix the issue.  My upgrade isn't up until June 2014 so not only do I have to wait for the upgrade and I am not paying for a new phone but I have to pay $10 plus extra a month on my cell phone bill because I was going over on my Data!!!  I have been beyond upset about this and Apple is not doing anything about this nor did they offer up some way to resolve the issue because obviously it is not just some rare incident if several people are having this issue.  Who knows how many people out there have had this issue and have not said anything about it.  Now there is a newer update that I can't do because it requires wifi in order to download.
    June can not get here fast enough and I may not go back to Iphone after dealing with this for so long with no help from Apple.

  • Wifi and bluetooth doesnt work anymore - Help

    Earlier today I was able connect my playbook to my home wifi network and blackberry tour through the bridge platform. Now I can no longer get bluetooth enabled on my tablet and it is unable to pick up not only my personal wifi network but others as well.
    I have a Linksys router with 2.4Ghz and 5Ghz Antenna, my playbook has always been connected to the 2.4Ghz band before. For some reason, it wouldtnt connect to the 5Ghz anyway. It wasnt a concern until tonight..
    Since I could not connect to Wifi anymore and couldnt bring bluetooth back on either, I tried multiple restart, hard reset and finally a security wipe, hoping it would bring me back to factory default at least.
    Now im back at the initial setup, but I still cant connect to my wifi. The 2.4ghz wifi wont even show in the available network, and even though I can see the 5ghz network, it wont connect.
    Connecting the playbook to desktop software at this point doesnt seem to work, it tells "Setup hasnt been completed for the connected Playbook. Disconnect your device and finish the setup" bla bla bla.
    Any other way to actually reset that thing ?

    My bluetooth was OFF and so was my Wifi.
    When I went into Bridge setup on the playbook, it said something like "you have to enable bluetooth to get bridge working" but bluetooth wouldnt come back ON anyway... so I dont know what crashed bluetooth + wifi...
    This morning I updated the playbook with Desktop Software, but Im still stuck in setup trying to connect a Wifi. It will shows an available network but when I try to connect it fails and then the network is just not available anymore. Im sitting 2 feet from the router.. cant be because there is a bad signal. The wifi network is also working for anything else trying to connect to it.
    I wish there was a way to get pass that setup without a wifi connection.

  • Sync and Bluetooth Not Working

    I have an Iphone 4S and an Ipad that will not transfer my itunes music from my PC to the devises.  My bluetooth is also not working.  I have asked Apple Support and they are unable to resolve the issue.  Any suggestions?

    To transfer music from your PC to your devices install the latest version of iTunes on your PC, then connect a device using the USB cable. Click on its name in iTunes when it appears, click the music tab, select the music you want on the device, and click "sync".
    What part of BlueTooth is not working? You cannot use BlueTooth to transfer music or other files. It is only for audio devices and their controls.
