Wifi and Bluetooth

I have a MacBook Pro. All of the sudden it's trying to use blue tooth instead of wifi. How do I change it back!

Can you post a screen shot of your Network settings?

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 :-)

TS1559 still no solution for greyed out wifi and bluetooth - what to do? been messing around with it for weeks and now discover I'm just outside of warranty period? WHAT?

I am in such a predicament - phone not been quite right since the 6.1 update and I was tolerating the inconvenience of switching off and on etc etc for the past couple of months and now the wifi and bluetooth are totally greyed out all the time - did every restore possible including back to factory settings - still no luck - please don't tell me that trying all the solutions over the past 2 months that temporarily worked for a few days at a time will now mean I have timed myself out of the 1 year warranty? arghhhhh (I can't believe that such an issue will create the response 'oh well, your problem - best just buy another one' ???)
I can't just drop everything and drive to the apple store and wait for hours every time there's a 'glitch' otherwise I may as well move nextdoor to the mall. They tell you to try and solve it yourself first - which I did - and now it's not responding to anything I try, will I be told - 'too late, out of warranty'???
I see theres an update for the iphone 5 that fixes wifi bugs - what about us 4s owners? even my 3 year old 3gs is still working on wifi (haven't dared to update it!) so don't start telling me to expect that the iphone will only last 13 months - NOT AT $600 a piece
This is madness and driving me crazy
Please has anyone had any luck fixing this problem???

well, you know how it is - glitches that usually resolve with a hard reset etc
then a restore. then a factory restore....then ..... nothing fixes so I try the next step with apple online - fill out my serial number and find it is a couple of weeks out of date - and then with the holidays who has time to get to the apple store? this is my second 4s handset as it is - first one the glass cracked from L to R without any impact/damage etc - they changed it out automatically because it's a 'known fault' apparently - so technically, this handset is only 6 months old - but warranty is from original purchase date -
never imagined it would turn out to be a warranty issue with the phone - and hey maybe when I get a chance to go to the apple store they'll be sympathetic, but I won't be able to get there till at least Jan 4th as it is. On the other hand, another iOS update might resolve the issue - but how long till that release? at the moment I'm having to use my old 3gs for wifi and 4s for phone!!!

Yoga 13 WiFi and bluetooth issue resolved

Unfortunately, I also met WiFi problems, but also found unexpected and sad solution.
Wifi worked pretty well at working place, but had problems at home. As an experiment I brought WiFi router from the working place home. It did not work!
At home I used pretty old keyboard and mouse plugged into passive USB hub. As soon as they were disconnected, problems disappeared. WiFi was also stable after I plugged power supply into the USB hub.
We are making 24-bit analog-to-digital converter that connects to the PC via USB. I exactly know its current consumption (300 to 330 mA) and know that it correctly handles USB rules about power regulations. Maximum current, specified by USB2.0 standard, is 500mA, so consumption of our ADC is within limits. As soon as I plug this ADC in, WiFi connection immediately disappears at the working place.
In the case of other devices, such as USB flash drive, power consumption may depend on the activity, increasing as it writes or reads something, and decreasing at the moment of inactivity.
I'm pretty sure that Lenovo placed their WiFi/bluetooth module on the same USB hub with right-side USB2 connector. Any device, that requires energy, being plugged into USB2.0 port, immediately destroys WiFi (and presumably bluetooth) and it is rather hard to get it back alive without special dancing around.
So, conclusion: never plug anything into USB2.0 port, if you need WiFi. This decreases number of available USB ports from two to one. Lenovo team should be blamed for that, not driver manufacturers or board manufacturers - Lenovo did non do its construction job well.
I am not sure, that all WiFi and bluetooth problems of Yoga discussed at this forum have the same reason. But in any case incorrect implementation of USB2.0 power should be considered before any other reason of malfunction.
Car manufacturers recall their products in the case of a failure. What about computer manufacturers?

Citation from Wikipedia:
The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire to power connected USB devices. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V ± 5%) between the positive and negative bus power lines. For USB 3.0, the voltage supplied by low-powered hub ports is 4.45–5.25 V.[61]
A unit load is defined as 100 mA in USB 2.0, and 150 mA in USB 3.0. A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0. There are two types of devices: low-power and high-power. A low-power device draws at most 1 unit load, with minimum operating voltage of 4.4 V in USB 2.0, and 4 V in USB 3.0. A high-power device draws, at most, the maximum number of unit loads the standard permits. Every device functions initially as low-power — but may request high-power, and get it if available on the providing bus.[62]
Obviously, WiFi adapter is a high-power device. If it does not have sufficient power, it will start power saving program by reducing speed. Even lower power may interrupt ins basic functions. When I connect another high-power device (HDD or ADC) to the same hub, it should get its 500mA from the hub. Seems that starting at this moment WiFi receives much less current than it requires and stops working.
If something is plugged into USB3 port, and this something does not utilize all energy it requested, WiFi starts working again.
I would greatly appreciate if somebody repeats my tests using Yoga or Yoga 2 Pro.
Test:
Reboot your system, all USB devices disconnected
Open http://www.speedtest.net site and measure Download connection speed (Speed1)
Connect external HDD to USB2 (NOT USB3!) port
Wait until HDD is connected
Test Download speed once again (Speed2)
Report results to this blog as Speed1/Speed2 couple of numbers
Thank you in advance

How can I tether via USB my iPhone 4S with iOS 7.1.1 to my MacBook with Snow Leopard 10.6.8 and iTunes 11.2.2 ?? Please note that at the same time Personal Hotspot via both WiFi and Bluetooth works perfectly!

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.

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

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.

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!

Downgrading the iOS is not supported at all.

Problems sharing internet to macbook over wifi and bluetooth

I have an iPhone 5S with iOS 7.1.2 and I want to share its internet connection to a Macbook Pro (early 2011) with OS X Mavericks 10.9.4.
When I share using USB connection, it works fine, but with Wifi and Bluetooth I have some issues:
- Bluetooth: I have never been able to make this work. I can't pair the iPhone with the Macbook. The iPhone appeared in the list of bluetooth devices in my mac, and I tried to pair it; in the iPhone a dialog asked me to confirm if I wanted to pair with the mac, and I selected Yes. After a few seconds it disconnected. If I try to pair from my iPhone to the mac, I get an error message "Device not compatible".
- Wifi: this sometimes works but is very buggy. Sometimes the iPhone wifi network is not visible to my mac. Other times, when I select the wifi network in the mac, I get an error message that says it was not possible to connect. I have to turn off/on the wifi and internet sharing in the iPhone several times to make it work.
This is all very frustrating. Is there a way to fix this?

Same issue here with WiFi using latest iOS version on iPad Air and latest Macbook Pro. In my opinion, "Personal Hotspot" (or tethering) is totally broken on iOS.
WiFi tethering works once and then I need to enable/disable hotspot or enable/disable WiFi to make it work again. Bluetooth is so slow it's unusable. Even over USB I have to reset the iPad a couple times a day as the internet connection is displayed as online but just not working any more. Very disappointing. "it just works (not!)".

My wifi and bluetooth are no longer active

Grey wifi and bluetooth

I have an old iPod that my friend gave me and I thing the wifi and bluetooth antenna is broken because in the setting they are both greyed out and I can't click them. If I take it in to an apple store can they fix it or replace it or what?

Apple will exchange your iPod for a refurbished one for:
Apple - Support - iPod - Repair pricing
Try here first.

Why did my max loose wifi and bluetooth?

Not sure if it was after last update or when. But my phone lost wifi and bluetooth. I didnt even realize until I got a data alert. I have tried a full reset witch made me very unhappy due to the apps I lost.

Usually if you just turn the device on and off may have fixed your issues.
A hard reset in my opinion is not necessary. If phone makers send out junk updates that actually make the devices work worse, they never should release these junk updates.
Is your WiFi and Bluetooth functioning now? Your apps are not lost since in Google play store select MY APPS then from the list simply reload them back on the device. Both free and paid ones.
Good Luck

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.

HT5957 My wifi and bluetooth do not function in iOS7 I cannot downloar iOS 7.0.2 without wifi ????

If you do not have Wi-Fi, do your updating using computer iTunes.
Make sure you have the latest iTunes 11.1 before you begin.

Problem with IOS 4.3.3 in Touch. No WIFI and Bluetooth detected.

There's not WIFI and Bluetooth since I've updated my IPod Touch to IOS 4.3.3. Anyone else have this problem? Thanks and greetings from Spain.

Here is Apple troubleshooting for that symptom. Just be aware, that you may have a hardware problem or require an appointment at the Genius Bar of an Apple store:
Unable to use Wi-Fi or Bluetooth with iPhone or iPod touch because there's no address listed for the device
