Windows 10: Qualcomm QCA9377 802.11ac wireless adapter with Bluetooth driver no Bluetooth available

I have the Qualcomm qca9377 802.11ac wireless adapter with Bluetooth however it has recently disappeared, ie: No Bluetooth in device Manager as well as the slider to turn Bluetooth on has disappeared. I tried everything I can find online to get it to return, exhausted many hours and eventually reset my PC I have a Dell Inspiron G5 5090. I downloaded all available windows updates as well as driver updates. Still Bluetooth does not show up in device manager nor does the slider appear in Bluetooth And Other Device Settings.


Please Help!


Kindly,

C Niles

Qualcomm Atheros QCA9377 Wireless adapter

Thanks JuanMoreno25,

I have carried out the process that you have described, however I carry this process out on a weekly basis as the fault comes up that the
Qualcomm Atheros QCA9377 Wireless adapter is not recognised.

I have updated the Qualcomm Atheros QCA9377 Wireless adapter (microsoft)

Is there anything else that I should be updating?

Thanks

 

Bluetooth Stopped Working in Windows 10 (Qualcomm Atheros QCA9377)

I have an Asus T102HA which has an integrated Qualcomm Atheros QCA9377 WiFi+Bluetooth adapter. The Bluetooth suddenly stopped working this morning and as a result the wireless mouse no longer works (this is how I knew Bluetooth stopped as I was using the machine at the time).

I checked in Device Manager and the Bluetooth devices were greyed out though they were not disabled (had to enable 'Show hidden devices' in Device Manager to see the Bluetooth section in the device tree).

I proceeded to uninstall and reinstall the Atheros QCA9377 driver as available from the Asus website (https://www.asus.com/uk/support/Download/3/919/0/1/EKnJ4vWdmuN3xLti/45/). Upon reinstalling the driver Bluetooth is no longer listed anywhere in Device Manager.

I have run the "Scan for hardware changes" in Device Manager but this does not detect anything new.

It is as if the Bluetooth device no longer exists on the system. However, WiFi is working fine which would suggest that the device itself is presumably ok and still present.

The only possibly suspicious thing to note in Device Manager is a device under:

I have no USB devices connected to the system so it is unclear what this unknown USB device is above - perhaps it could be the Bluetooth adapter but I don't seem to be able to get that unknown device to find a driver update online.

The Windows 'Bluetooth Support Service' is running and can start/stop successfully - it is also set to Automatic startup.

Airplane mode is not enabled and toggling it on/off has no effect on the Bluetooth situation, though it does turn WiFi on/off as it should.

I am out of options that I know of to troubleshoot this as Bluetooth isn't showing up no matter what I do.

How can I troubleshoot further and get the Bluetooth adapter reinstalled properly?

 

Accidentally uninstalled Bluetooth driver

Did you keep the Qualcomm QCA61x4A/QCA9377 WiFi and Bluetooth Driver I asked you to download earlier? If so, try to uninstall the Wireless driver as well under "Network adapters". I notice that the wireless card of your PC is for both Wireless (WiFi) and
Bluetooth. Then re-install the Network driver using the downloaded Qualcomm QCA61x4A/QCA9377 WiFi and Bluetooth driver.
