No wifi or bluetooth on Yoga 13 Realtek failed

I bought a used Yoga Ideapad 13. The Realtek card has probably died and there is no wireless or bluetooth. I've been into device manager and under network adapters there is no sign of it. Just to indulge in a bit of magical thinking I downloaded drivers for the non-existent card. I'm using a USB wireless dongle instead but to have 2 separate dongles for bluetooth and wifi is irksome.
I went into BIOS and made sure that wireless was enabled.
I updated from W8 to 8.1 but it made no difference, in neither case was the Realtek operating.
Has anyone resurrected the Realtek card? Or relaced it?

Is there even a wifi card in the machine? Open it up and see if a card is there. If so, then we will need to take you over to linux and some terminal commands.

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

Same here, 4s working perfectly, downloaded update 8.0.1 Now no wifi or bluetooth or hotspot. Control on/off icons are muted in colour and don't respond. Tried resetting network connections then total restore, didn't work so still have the same probl

I would try another restore of the hard disk to its original out-of-the-box contents using Toshiba recovery media. Maybe something went wrong in the process. Make sure everything works before applying any updates and adding any hardware or software.
Then add things carefully, rebooting Windows and testing the USB and audio at each step.
Please note this.
The only info windows gives me for the sound card is that it from Microsoft... with a driver version of 6.1.7601.17514....which naturally doesn't really help me since I have no idea what card or mobo I have . Is there any way for me to find out what I need other than opening up my laptop?
Every one of them lists my mobo simply as a Toshiba motherboard, with no audio card information. Which I'm assuming that is because it has an internal sound processor. My problem is that none of the properties, or ANYTHING I try, will give me information on what I need to fix this...
All of the latest drivers for your model are easily found here. This one is for the sound.

Wifi and Bluetooth disappeared after reset laptop to Factory settings

After reset my PC to factory settings realized that the wireless and bluetooth were not working. The problem is not with my home network, since all other devices are working great The F12 (wi-fi) hot key is orange and does not turn on. When button is hit just changes to airplane mode on/off. There are no option of wireless devices or icons or whatever to access this. Wireless and bluetooth just disapeared. At the device manager, the only driver found in Device Manager\Network Adapters is Realtek PCIe GBE Family Controller. Nothing about wireless. Everything is gone. Accessed the HP support and installed several different network drivers, but nothing happens. Tried to do another factory reset, problem persisted. Exactly same occuring to Bluetooth. They always worked fine, till the factory reset. Don't now what else to do, some say that may be a hardware malfunction, but I think it is weird, always worked great and it changed immediatly after the factory reset. In my opinion seems more like a software than a hardware issue, caused by the reset. Could anyone give a help with that? Tks a lot

Hi , Thank you for visiting the HP Forums! A great place where you can find solutions for your issues, with help from the community!
I came across your post about the Notebook, and wanted to assist you! I have looked into your issue about your HP ENVY TouchSmart 15 Notebook and Wifi problems. Here is a link to the troubleshooting the Wireless connection. Here is a link to the HP Support Assistant. Just download and run the application and it will help with the software and drivers on your system it has built in Wireless troubleshooting assistance. It will show you how to make sure the Wireless is on. Here is a document on Airplane mode. If Airplane mode is on you cannot use your WiFi or Bluetooth, so Airplane mode should off and no Ethernet cable connected for the Wireless troubleshooting. I hope this helps you connect. Thanks.

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 I must say I am very dissapointed with some of apples ethics. I have spent thousands of dollars on iphones and ipods not to mention hundreds in the itunes store, I now have a iphone for I cant even get wifi or bluetooth on?

I have tried every suggestion availiable. I have no service to my iphone 4 and would just like to use it as an ipod. I cannot connect to wifi no matter what I do, infact i can't even turn on wifi because it is will not move, like it is frozen or something. I am really choked that wifi and bluetooth are not availiable to me. I also dont not understand the reasoning in charging me 35 dollars to talk to someone about a products apple sold and provided me with. I have spent thousands of dollars on apple products over the last few years for kids, myself, and family, not to mention I have spent thousands in the Itunes store for these products that are of no use to me. It absolutely disgusts me! I also bought an i pod touch for my stepson four or five years ago. He came to me the other day and asked me if he could use one of my Ipods. I asked him where his was? He told me it never worked right from day one and kids being kids, he never told me. So I plugged it in charged it up and all it does is is make static when it's turned on. You cant even listen to music on it. with head phones or otherwise.

Do you have a question?

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!!!

Iphone 5 will not connect to home wifi or Bluetooth after iOS 7.1.1 update! Using unnecessary data please help!

My iphone 5 will not connect to my home wifi or Bluetooth after I completed the iOS 7.1.1 update. Before the update I was able to connect to my home network with no issues. Now it rarely finds my home network (unless I'm right in front of the router and even still the signal is weak) and when it does find my home wifi network it frequently disconnects from it. I followed previous suggestions to turn off router or forget network settings and re-establish them but it continues to happen.
This also happening with my Bluetooth connection. My iphone 5 would automatically connect to my home phone Bluetooth prior to the iOS 7.1.1 update. But now my device no longer connects, which means my home phone no longer rings when my cell phone is ringing.
I probably would be less worries if I did not have to monitor my data usage with Verizon. However, I do have a limited amount of data to use and I recently reached the max and had to pay extra money due to my wifi being unable to connect. Can anyone please help me with fixing this?

If you have Applecare take it back to the shop and demand a replacement. If not you're stuffed. It's a bug that they've put in the software to get you to buy another iphone. You can maybe warm it up with an hairdryer near the speaker and then turn it off and put it in the freezer for 10 mins then retstart it and wi-fi is there. It could also be a problem with the chip, if you do the freezer thing it comes back.
Apple knows its a problem as there are millions of people out there that it is happening to, in my opinion get shut and get a Samsung!!!! That's what i've done and love my new Samsung S3 Mini miles better than the iphone!!!!
Go on youtube atnd look how many millions of people this has happened to.
Someone needs to put this in the media so they will actually do something the robbing bleeders!!!!!
Also whatever you put on these discussions will get it wiped if Apple don't like what you put!!!!

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!
