Missing Bluetooth Device in Windows 8.1

I recently purchased a Cyberpower PC Fangbook laptop with Windows 8.1. I reset the PC, but upon re-installation of Windows 8.1 from the accompanying disk, it could no longer connect to the internet. When I attempted to manually activate the device, I found
that it was missing (according to the device manager). As I understand, this actually means the driver is absent or something? Any clue what I'm supposed to do about this?

Hi,
Did you install the right Bluetooth driver?
I suggest that you uninstall the driver and reinstall it to check the result.
Also,please download the latest version from manufacturer website.
Regards.

  • Problems Connecting Apple Bluetooth Devices in Windows using BootCamp

    People are having trouble connecting bluetooth devices in windows 7 while using bootcamp. I solved the problem by clicking on bluetooth>ADD A DEVICE once windows has detected the bluetooth device you want to add. Now, right click on the device you are adding (make sure it's  "inside the add bluetooth
    Device window "see below" ) it will say "select your device". Then tick the box beside "drivers for Keyboard, Mice etc.," under "Bluetooth Services" (see below) and it will search the internet for your drivers and automatically install them. If you have any problems post a message. Good Luck

    Not sure if you can help me, but I can't add my phone or some bt speakers to my MBA2011 in bootcamp.  Drivers can't be found...and this is usually a problem of the bt controller drivers, not the device.
    It does seem the apple bt drivers are gimped in bootcamp.

  • Bluetooth device driver - Windows 7

    I am unable to  successfully add my Blackberry 9700 as a bluetooth device paired to my Windows 7 64 bit laptop in order to use the wireless syncing function.  When I attempt to pair the device, I receive the error message "device driver was not successfully installed" and "Bluetooth peripheral device- no driver found."  The properties display 2 missing drivers. Can someone advise me from where I can obtain these missing drivers.  I am using Desktop Manager 5.0.1.28.  Thanks

    Go to the site for directions. You have to add the drivers manually.

  • Connect a Bluetooth device in Windows to a Bluetooth Device in Linux to obtain the RSSI

    Here's the situation. I have looked through the forums for information on this question. I do understand there are some compatibility issues between Windows and Linux, hopefully this is easy enough to not be a problem.
    I'm trying to acquire the RSSI (Received Signal Strength Indicator) for a Bluetooth card - any card for that matter. Windows Native Drivers will not allow me to access this information through the HCI commands, I've looked. However, Linux does, it's easy, and I now know how. The plan is to get the Windows Bluetooth card to communicate with the Linux Bluetooth card and have the Linux box send the RSSI information to the Windows box.
    This program, which I've been working on, needs some help. I would like to put it up to test tomorrow afternoon - when I get off from work. I would like to get some recommendations and suggestions on how to fix the empty parts. And if there's a better way of doing this.
    This program is part of another program written in Labview for image recognition.

    I haven't worked with BT, so I'll assume the basic connection works (you open a connection and you get the data). I'm also assuming the linux box isn't running LV (if I remeber correctly, BT in 7.1 is only supported on windows XP).
    So, to comment on your code:
    1. I dislike flat case structures which span across multiple screens. I prefer using stacked ones if necessary. This is obviously matter of personal taste and screen resolution, so it's just an obsrvation.
    2. Your connection will run not once for each connection, but until it encounters an error.
    3. I made a few other quick modifications. They're ugly, but they should set you on the right path. I may have missed some of your notes.
    Try to take over the world!

  • No Bluetooth device detected on Lenovo G460

  • Cant get bluetooth device to wake computer

    Hi, i have winows xp on my macbook. Im using an external monitor with the laptop lid closed. So i was wondering if there was a way to wake the laptop up from hybernation by using my external keyboard and/or mouse. As at the moment i have to open the laptop lid and use the track pad untill it starts up and recognises the bluetooth devices again. I can get it to work flawlessly in OS X, just not in XP.
    so can anyone help me an tell me how i can get my wireless bluetooth mouse to wake windows xp?
    Thanks.

    Same problem here. Mac OS has an option to wake on bluetooth devices, but windows doesn't seem to have such an option. There is a Microsoft Knowledge Base article about this:
    http://support.microsoft.com/kb/266283
    that describes the solution as
    "To resolve this issue, see the documentation that is included with your computer. Alternatively, contact your computer manufacturer for information about how to configure the BIOS. "
    In other words, there would need to be a BIOS setting in boot camp that would allow the Bluetooth receiver to be active in the sleep state, just as there is in Mac OS. Maybe there is such a setting, but I haven't yet found it. I'll keep looking.

  • Bluetooth compatibility with Windows on iMac?

    My wireless Apple keyboard and Mighty Mouse work great under Tiger OS. When I first went into Windows, I plugged in the wired keyboard and mouse and registered both Bluetooth devices under Windows, and they worked fine. The wired items went back to storage.
    When I close Windows, go to Tiger, everything still works fine but when I go back to Windows the wireless devices have lost their registration. I've re-set them up several times but it happens every time. Anyone have a suggested way to register the bluetooth devices with Windows so they will stay registered?
    Thanks!

    Currently, the Apple Bluetooth Radio does not work well in Windows. There is just some sort of incompatibility which keeps Windows from keeping Apple (or Microsoft, for that matter) Bluetooth devices registered in Windows. The same is true if you use Microsoft Bluetooth devices in OS X.
    I have the same problems using my Microsoft Bluetooth Desktop set with my Intel iMac in Windows or OS X.
    The Apple hardware and software just is not very compatible with Windows, nor is the Windows hardware very compatible with its own software or with OS X.
    I guess we will just have to wait until both Microsoft and Apple improve cross-platform compatibility.
    Sorry, but I have no answer for you other than that. They just don't work as they should right now.

  • Windows 8.1 Bluetooth missing from Device Manager

    It appears after the latest round of windows automatic updates my native bluetooth device went missing.  It is not visable in the device manager or the control panel settings.   I have downloaded and reinstalled the latest wireless and bluetooth drivers, however I am still unable to view the device.  This is a Yoga Pro 2 (64bit) running the most current Windows 8.1 updates.  The latop has a native bluetooth adaptor which had been working with no issues. I have run services.msc and restarted the associated BT services and they are running. Would appreciate any help.

    Are these the drivers that you updated?

  • Windows upgrade to 10, but missing bluetooth driver.

     Just automatically upgrade to win10 , when bluetooth device is missing.
    I already go to hp cs, but they told me, if I upgrade software, they won't fix this problem.

    , Thanks for posting back.  By using the drivers from Intel directly you may not have functionality.  The drivers for the notebooks even if they have the same series and so on are usually proprietary.  Use any direct drivers at your own risk.  The other option you have is to run the Windows 10 update trouble shooter. Here is the link for that. Windows Update Troubleshooter. Run all updates including the optional update and it should repair most issues.  Besides that you would have to use any drivers that are released on the HP support site once they are given to HP. Thanks again for posting and have a great day.

  • No sound on my Sony Bluetooth Headset because Windows 7 can't find Bluetooth peripheral device driver

    SO, I am dealing this problem for the second day in a row and no working solution still. I own the latest iMac 2014 (though the model is exactly as 2013) 2,7 Ghz with Bluetooth 4.0, I've installed through Bootcamp Windows 7 x64. My bluetooth headset Sony DR-BTN200 http://store.sony.com/bluetooth-headphones-zid27-DRBTN200//cat-27-catid-All-Home -Theater-Headphones (which is on Bluetooth 3.0 and of 2013 year model) is working fine with Mavericks and Yosemite on my MBP, but not working as it should on iMac with Windows 7..
    THE PROBLEM: I find the headset, connect it, but afterwards Windows writes that no drivers for Bluetooth peripheral device were found (3 or 4 encriptions like this, so, 3-4 drivers needed). The headset itself guarrantees fine working with Windows 8, the producer doesn't give any drivers to install, you won't find them on Sony's website - it should work as plug-n-play, they say those drivers are preinstalled on Windows 8.
    WHAT I'VE TRIED: So, the problem, as I've read from many-many-many sources is common for everybody running Windows on Mac devices. In cases with notebooks it is easy to solve (if you know it) - download the Bluetooth software from Broadcom (the producer of Bluetooth adapters/receivers of  Macs) http://www.broadcom.com/support/bluetooth/update.php - install, it finds the devices and istalls correct driver. This worked with my MacBook Pro 2010, on iMac it stucks on recognizing devices - nothing happens next, like it doesn't recognize any bluetooth device. Downloading many other drivers packages didn't help either, nor Toshiba Bluetooth helpers could detect Bluetooth headset to properly download the correct drivers (though it was already recognized by Windows, just couldn't connect properly), nor different other programs like Bluesoleil, Blue manager and so on.
    On other notebooks and computers many try to install manually the drivers, usualy Microsoft Windows mobile-based device support. I've tried to install many drivers, all of the Broadcom drivers I've found (including the Broadcom Bluetooth 3.0 USB driver that makes the headset work on MBP), and I must say that Windows recognizes (doesnt show the yellow triangle next to the icon of the driver) only for the Microsoft Windows mobile-based device support driver. Though it's like that, the sound still is not playing out of my headset. On MBP after the drivers were installed, I chose the device in Printers and devices and there was an option of Control (maybe I remember the name wrong), it went first in the right-click menu, and aftewards there was a page were I could connect my headset through ticks/checks on different options. Nothing like this appears if I install any of the drivers on iMac (nor Broadcom, nor Win mobile-based). I must also mention, that some kind of package that I've downloaded from Toshiba or Acer's Broadcom Bluetooth kit, I don't remember, installed some bluetooth drivers (Bluetooth Audio, "receiver" if I recall it correctly and 2 more), that were recognized as right drivers for peripheral device when I connected my headset, but even then - no sound came out of the headset.
    HELP ME: What shoud I do? I've tried all of the methods that are on the net. Sony store won't help me out, because the problem is not in the device - it's in the software/hardware of "your iMac". The headset works with Mac OS, should work fine with fully-Windows PCs, it just doesn't with iMacs on Bootcamp Windows. The interesting thing is that updating windows to Windows 8 might also not help, since Sony guarrantees only work on pre-shipped with Win 8 devices, not with the upgraded devices. I do think the problem is with drivers, that Mac's Bootcamp utility doesn't come with pre-installed Bluetooth drivers for connecting Bluetooth headsets, only for the Apple mouse and keyboard. I must also mention that I've tried to install manually many of the Broadcom drivers, all of which were for Bluetooth 3.0 or 4.0, they didn't help.
    It's awfull that I've got the latest iMac, so the latest hardware and face such problems. I only think that a cheap 5-7$ bluetooth-usb adapter could help, maybe it could recognize the headset and therefor install its own drivers for its manufacturer. But I don't imagine how would it work and connect since iMac has a peinstalled Bluetooth receiver. Is there a software sollution? An app or driver?

    So, finally I found what worked for me: Re: Full Bluetooth functionality in Bootcamp (audio, A2DP, FTP, OBEX) third variant, none of first 2 worked.. The only trouble was to find the correct link since on Acer site there is no download link. I've googled for "Bluetooth_Atheros_7.4.0.96_W7x64_A.zip" since this is the archive the guy is actually talking about. The 4th link on google was http://www.laptop-software.com/Acerdriversdownload.php?GDFiles/Driver/Bluetooth/ Bluetooth_Atheros_7.4.0.96_W7x64_A.zip?acerid=634556349384706773&Step1=Notebook& Step2=Aspire&Step3=Aspire%204830Z&OS=721&LC=en&BC=Acer&SC=PA_6 and I chose to downlad from the first download link. Then the steps are:
    1) unzip the folder
    2) don't look for x64 or x32, there is only a one installer called "Bluetooth_Suite_win7"
    3) install Bluetooth_Suite_win7
    4) after it installs Windows starts downloading and recognizing drivers, I don't know how it actually works, but it also downloaded and recognized the unrecognized before drivers for my Bluetooth headset.
    5) Restart Windows
    6) Turn on headphones - they connect automatically, everything works and works great, the quality of sound is exactly the same as it was on Mac OS, nothing that would bother me.
    ****, it took me 2 full days... finally...

  • ThinkPad W540 - Win7 - Bluetooth device not recognized by Windows 7 - REALTEK not supported OS !!

    In my Device Manger there are three devices that are working properly the are:

    My guess is that you are trying to install the driver for a newer machine (different Bluetooth device). I believe you need this one:

  • Windows Vista - cannot use Bluetooth device TRENDNet TBW-102UB

    Hello,
    I'm facing a problem that occurs when try to connect Bluetooth device on Satellite A135-S4637 with Windows Vista Home Premium.
    The Bluetooth device is a TrendNet TBW-102UB, and at XP it's working just fine.
    The error message is "Bluetooth device is not ready".
    After install new updates from manufacturer's website the problem still occurs.
    Is there any service pack from Vista that fix that kind of problem or it is something relational to Toshiba's Bluetooth software?
    Thanks,
    Daniel

    Hello
    Please do not be mad on me but I do not understand relations to Toshiba notebook. Are you 100% sure that all USB ports on your notebook work properly?
    If yes the whole thing has something to do with this external device, driver and settings. To be honest the manufacturer must offer Vista compatible software. Do you think so?

  • X230 with windows 7 still won't connect to any bluetooth devices after many attempted solutions

    My starting point:
    I have 6 month old x230 with windows 7, all windows and lenovo updates already completed.  The bluetooth logo exists on the bottom of screen but when I try to "add device" it doesn't recognize any bluetooth devices.  I've tried this with speakers from 3 different companies.  I have updated the bluetooth drivers, the windows and lenovo programs say "device is working properly".  Nothing wierd in device manager.  I have  microsoft bluetooth enumerator and thinkpad bluetooth 4.0.  One time for about 30 minutes it worked on a ECOXGEAR bluetooth speaker but then also stopped.
    Since then:
    I enabled settings in BT control panel, BT is enabled in BIOS, BT wireless on, have tried to rollback driver to previous versions of BT but not possible, devices still do not show up in Add new device window. 
    Latest update:
    I have uninstalled the lenovo bluetooth software following a suggestion and now my laptop no longer has bluetooth capacity at all - it seems when uninstallig the lenovo bluetooth sw the microsoft sw uninstalls as well.
    Solved!
    Go to Solution.

    Seems BT audio profiles your speakers need are absent in the sw installed on the laptop. Try BlueSoleli or Toshiba BT drivers, both of them might have needed audio profiles. Toshiba stack seems a bit better quality but needs some tweaks for installation.

  • Lenovo Wireless Device Settings Window is missing, G580 (20150) Windows 8.1

    Since upgrading to 8.1 I have been unable to access the window to toggle wireless and bluetooth on and off.
    I reinstalled LEM and the airplane function returned, but not the window.
    Wireless works after I removed the Microsoft driver. I don't have a bluetooth device to test that function.
    I just tried to install the 8.1 64 bit Bradcom Bluetooth driver and it would not install.
    Bluetooth isn't listed in Device Manager.
    I just found this information, but the link to the older version doesn't work.
    I may just by an Intel Network 7260.HMWG.R

    I have the same problem. G580, model 20150. I clean installed W 8.1, deactivating UEFI, but the Bluetooth device isn't discovered. I installed the appropriate driver, but the issue remains. I believe it's a driver issue. How can we contact Lenovo to tell our problem? They don't provide an e-mail adress, unfortunately... I'm wondering why?
    EDIT: by reading the post #3 on this thread, by Solid_Cruver, I uninstalled Lenovo Energy Management for W8.1 x64 and installed older version as suggested. Then pressed Fn+F5 as I used to do in Win 7, activated BT, reinstalled appropriate driver and... Voila!, I have functional BT! Yupi!!!
    Thank you very much, Solid_Cruver! Good solution!
