Qualcomm Atheros Bluetooth not working with Windows 8.1

Anonymous

Hello,

I am using a brand-new Samsung Atib Tab 3 tablet (XE300TZC-K01FR). I have installed the latest windows 8.1 release and now cannot use the bluetooth keyboard anymore. Seems that the issue is coming from the bluetooth card drivers (code 10 error - cannot start). What should I do now ?

It is impacting dramatically my work productivity as I can now only use the virtual keyboard. Will a fix be published very very soon?? I do not understand why it is always such a pain with Microsoft products. No wonder the company is loosing marketshares.. I do not expect revolutionnary products but at least something that do work properly...

Thank you for your support.

Hello,

I had the exact same problem and fixed it myself. Here's how to do this:

Go to device manager and find the Qualcomm Bluetooth Atheros device

Then double click on it and on the drivers tab, select uninstall driver but make sure that you select "Remove driver from computer" or something to that effect.

Then rescan your computer by clicking on the small rescan icon on the top left of the device manager window.

The Atheros device will now show up as unkown device. Open it up and select install driver and don't select internet but select C: drive and check the subfolder box.

It will take a while but after a few minutes, it will install the right driver and then you need to repair your keyboard.

Cheers!

UnInstall Bluetooth drivers and re-install Bluetooth drivers meant for Windows 7 or Windows 8.0 in "Windows 7 Compatibility Mode".

I had tried all suggestions and troubleshooting steps including disabling power saving options, doing a factory reset and clean install of Windows 8.0/8.1 but I continued to have problems with Microsoft Bluetooth mice (w/o USB dongles) randomly disconnecting. The ONLY solution that worked for me was un-installing existing Bluetooth drivers from Control Panel as well as Device Manager and re-installing Bluetooth drivers meant for Windows 7 or Windows 8.0 in "Windows 7 Compatibility Mode". The key here is installing Bluetooth drivers in "Windows 7 Compatibility Mode" by right-clicking the Bluetooth EXE file > Properties & selecting "Windows 7 Compatibility Mode". Avoid Bluetooth drivers meant for Windows 8.1. Luckily, my touchscreen laptop manufacturer (Acer) had both Windows 7 & Window 8.0 Atheros Bluetooth drivers for my model on their support website. Additional side-benefits I noticed after doing this:
1. All three models of built-in Bluetooth Microsoft mice (Microsoft Scuplt Touch, Sculpt Comfort & Bluetooth Notebook Mouse 5000) started working perfectly without any sudden disconnects or freezing;
2. The overall mouse operations also became lot smoother and predictable;
3. Windows Power Management started working perfectly with the laptop going into sleep / standby nicely and waking up instantly without any lockups or WiFi issues
4. CPU / Fan noise is much quieter-- it seems the Bluetooth drivers installed as I suggest are more "in harmony" with the rest of the system.
5. Everything including the Bluetooth mouse is working great for almost a week since I made these changes. I promptly updated my complete system image backup with the new setup.

Hi everyone,

If you have a Win 8.1 Machine with built-in Bluetooth from Qualcomm Atheros Communications, the Bluetooth may no longer work after you've upgraded to 8.1; this happened to me.

If you go to Device Manager, there is a Bluetooth section and in it there is a thing called "Bluetooth USB Module." Actually, the Qualcomm Atheros Communications Bluetooth is built into the Wifi Adaptor, but that does not really matter.

Acer (but probably other manufacturers as well) have not updated the drivers for this device to Win 8.1 yet on their sites. The Atheros website is also useless.

I found the Win 8.1 Driver (64 bit) here: http://drivers.softpedia.com/progDownload/Acer-Aspire-V5-573P-Atheros-Bluetooth-Driver-801305-for-Windows-81-64-bit-Download-306204.html

I have an Acer Aspire Desktop, so I can verify that it works for Acer. Might also work for other PC Manufacturers, but not sure.

It's a big download (over 300 mb), but it fixed the issue for me:

Download the zip file; extract all

Open "Install CD" folder

Find "setup" and run it

Restart machine after it's done

Good luck!

Fix is confirmed to work on Aspire Model m5-581T. I had issues with my phone connecting to my aspire via bluetooth. This driver worked to connect the phone. Well done mate! Good show!
