Go to search and search device manager select settings (in the search between Files and Apps). there you will find "network adapter. " see if it is listed.

Ya, i have network adapter in device manager but there is no bluetooth adapter.,in that case my wifi is working well ..do i need to download "microsoft generic bluetooth adapter"...or anything else??

I heard some built - in adapters are not compatible with certain OS, but in your case the company has installed it and is no chance of such. Install a program named driver booster, and download the latest driver.

I have the same issue with my ASUS Q500A laptop. Last week, I had Bluetooth, this week after some new Windows 8.1 updates, the Bluetooth ICON is gone, when I type "Bluetooth" in the search box I get the typical "bluetooth settings" option, but when I click on it, it no longer takes me to the bluetooth on/off page, but just my desktop. It's like the latest Windows 8.1 update removed the capability to see the Qualcomm bluetooth driver. So I downloaded the driver from the support.asus.com website, installed it, and still can't find a bluetooth icon or settings in my device manager or in the control panel. The bluetooth services are running, but no way to enable or see any bluetooth settings including the icon. Windows 8.1 sucks! Any ideas?

asus_user · Jun 21, 2014

I just fixed it. Here's what I did.

I uninstalled the cyberpower UPS software I installed last week. Then, I uninstalled the Qualcomm Bluetooth drivers I installed today (downloaded from the ASUS website). After a restart, I typed "bluetooth" in the search box and for the first time since last week, the "change bluetooth settings" link appeared. I also found the bluetooth icon to reappear in the device manager. Therefore, the UPS backup software kills the Bluetooth on Windows 8.1, remove it! Bluetooth is more important than some USB UPS power monitor SW.

pankajramoul :

yes you can do one think resotre your system to back date where there is a not recent window update. and after that you can make your window update off to get rid of this problem in future

I am presently experiencing the exact same issue at present.

I have a Sony Vaio 15A laptop, running Win 8.1 with 64 bit architecture. Up until an hour ago, bluetooth was present and running just fine. However, it's now gone! The only change? Installation of Kaspersky Internet Security 2015....

The only mention of Kaspersky on my system now is, within the Airplane mode of Network Settings, where Bluetooth is listed below WIFI, but is a greyed out box that cannot be toggled on/off anymore. Also, there is no mention of a bluetooth radio anywhere within Device Manager either - simply an "unknown USB device" now showing in the USB controllers section, which wasn't there previously.

I'm about to uninstall KIS 2015 and rollback to KIS 2014 instead - I'm betting that as soon as KIS 2015 is removed, bluetooth will be restored. Will report back either way when I've sorted it...

rjsdavis · Feb 28, 2015

I'm now really confused. I have rebooted the machine in the meantime prior to about to removing KIS 2015. I don't know why, but I checked the bluetooth one last time, and extremely mysteriously, it has re-appeared and reactivated and is working again. I cannot explain this at all. Therefore, at the present moment, KIS 2015 appears to be running, no longer overloading my computer (it had pushed my processor demand to between 92-98% and was seriously overheating my laptop as a result!), and no longer blocking Bluetooth

I don't understand why this is - but it's managed to restore itself. I did nothing apart from reboot.

Unsurprisingly, the bluetooth entry in Device Manager is also restored, and the "unknown device" in the USB section at the bottom has now disappeared...

Fking Microsoft and Kaspersky!

I am having a similar issue with an MSI GT70-20D I attempted to connect a Bluetooth keyboard after updating the Atheros WiFi adapter driver. There were no Bluetooth settings available. I then went to the MSI website and got the latest Atheros Bluetooth driver, performed and install, and restarted. At first the Bluetooth driver popped up in device manager as well as in the stupid W8.1 devices page. When I attempted to pair a device, it disappeared right from under my curser. I went back to device manager and it was in a continuous loop of refreshing. The first few times, I saw the Bluetooth driver appear and disappear, then it disappeared altogether. I though maybe my driver download was corrupt, I downloaded and installed again--same result. What I am wondering is if I did not delete the old driver, is it in there somewhere causing me problems?

Please create a new thread rather than reviving old ones.

Use a link to the old thread if it has relevant information.

MatthewWin81 · Mar 26, 2015

This iswhat works for me every time.

Right click on start menu.
Select device manager
Right click on your Bluetooth adaptor.
Select enable.

This fix works every time in my experience on a existing install. Haven't experienced any issues with Bluetooth on new installs.

Hope this helps.

I own a Sony Vaio SVE15128CNB with Windows 8.1 and was having same problem. Bluetooth was not even listed in Device Manager ( No special bluetooth list and not even in Network Adapter ). Their was no bluetooth toggle switch on/off key. I tried installing new drivers and try to use .inf files for Add a Hardware and also tride VAIO Care > Recovery and Maintenance> Reinstall drivers and software. But got no luck.. I also contacted Sony and they said go to service center and they will delete all your data and install a fresh copy. ( Well that was insane.. Just for bluetooth.. no way..)
------------------------------------------------------------------------------------------------------------------
Here is thing worked for me..........

I installed VMware-workstation-11. ( A virtual OS installer with in your current OS )
Then downloaded Windows 7 ultimate.iso
Then installed windows 7 ultimate from VM-ware.

I found that in my win 8.1 their was listed tab of Bluetooth. And then just installed drivers which I had already downloaded form sony website.

Then uninstalled Win 7 and VMware.

( just google all these file you will easily get or download it from torrent )
----------------------------------------------------------------------------

I think any VMware above 7.0 version can work and any Windows OS above Windows XP.

May be my pc was not detecting software patch of Microsoft Bluetooth Enumerator and Microsoft Bluetooth LE Enumerator. May be just installing this two software can also work for running your Bluetooth. (May be I am wrong for this part)

I had the same problem, and what worked for me was opening the device manager, uninstalling the current bluetooth device it detected, and then scanning for hardware changes. Brought the settings right back.

Same problem on month-old £199.99 cheap and cheerful Toshiba Satellite C50-B-14D running Windows 8.1 . Tried various inbuilt Windows diagnostics and supposed re-install of driver via the Toshiba gubbins already on computer, but to no avail. Dug out an old Argos BD-01 Bluetooth USB stick and instantly restored streaming of Jamaican dancehall tunes to wireless speaker again. Inelegant but functional! Might try following some of the procedures suggested on this forum to return a state of elegance. Windows 8.1 obviously does support stuff like Youtube and Skype in their latest incarnations in a way that Windows 98 S could possibly not even begin to, but as for speed of opening folders, document files and picture files there's no noticeable improvement in 16 years!

Had a similar problem, Bluetooth worked fine, and out of nowhere, the device wouldn't connect. The Bluetooth option in the windows 8.1 charms area was gone, and there was no way to enable Bluetooth.

What I wound up doing is going to bios during computer startup, disabling wireless LAN, then logged in. Then I turned off computer, went into bios during startup, and enabled wireless LAN.
Bluetooth was back, and my device connected right away!

Paulson07 · Aug 31, 2015

Did you get any solution to this? I am facing the same issue. Tried lot of things and not working.

Paulson07 · Aug 31, 2015

Did you find any solution? I am facing the same issue in windows 10.

Mogar_92 · Jan 10, 2016

Hey, this answer may have already been posted elsewhere and I just didn't notice but here goes. I'm running Windows 8.1 on a Toshiba S55T-b Satellite laptop and I had the same problem for about a day. Then by fluke I managed to fix it. This doesn't even require you to restart your machine!

Search "Device Manager" in the start menu. When that pops up, right click on your computer's name and select "Scan for hardware changes". If the Bluetooth still doesn't show up after that, scroll down to "Universal Serial Bus Adapters" and open the drop down menu. For me at least there was a device that said something along the lines of "Unrecognized USB: Error 43." If you see that, double click it and when the window pops up, click on "Disable". This will slow the machine for a second while it disables the device and reboots it, ultimatly bringing back your Bluetooth with no problem what so ever.

Hope this helps someone.
