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

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!!!

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.

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!)".

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.

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.

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?

Sorry to hear that you have issues with WiFi and bluetooth
I'm afraid this sounds like it may be a hardware issue in your phone but i recommend that you first try to reinstall the phones software using PC Companion but please note that this will reset your phone and delete all your data.
If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, please contact your local support team.

HP Pavilion Sleekbook 14 windows 7 wifi and bluetooth disabled

Hi,
I successfully downgraded Sleekbook 14 into Windows 7 64 a while ago.
Everything worked fine.
Now, after reinstalation of Windows 7 clear,
I cannot turn on Wifi and Bluetooth, and even cannot install drivers.
I tried several differnet wifi drivers.
I tried to use drivers which I used previously. No success.
I have Ralink module inside.
Drivers did not installed. In hardware list of Windows I do not see network card.
F12 LED still flash in orange. Fn+F12 nothing changes.
I cannot force it to blue light.
When I use Window Add Hardware... I see blank window. None hardware detect, and even I cannot select new harware manually. Is it normal?
Could it be module smashed? Does it happen? How to verify finally?
I do not see any network card or option in BIOS. Should I?
