Qualcomm Atheros AR3012 Bluetooth not working in Windows 10 I hope you'll be able to help me, I am tired of spending hours on this ! Of course, I can't get Bluetooth anymore elsewhere, not in settings, nor in Network settings. So I can't get the AR3012 Bluetooth driver back, and I have no more way to do this. The installation runs well, asks me to restart the computer, but there is no improvment at all. I've downloaded the AR3012 driver from there, and I tried to install using both normal method and running in compatibility mode. There is now no more qualcomm driver in device manager, nor BT card available. In normal use, I can see in the Device Manager panel the qualcomm driver (AR3012), and the Bluetooth Network card in "Network and Share Center". Furthermore, the bluetooth driver has disappeared since I tried to reinstall it, and I can't get it back. I'm used to solve my computer issues on my own, but today I can't.įor some days, I cannot use the Bluetooth anymore on my laptop. A fix would be higly appreciated.Ĭan't install Qualcomm Atheros AR3012 Bluetooth 4.0 + HS driver Sometimes the system cannot detect what kind of device it is, meaning a speaker would not transmit any sound. Worth mention is also that if the bluetooth device shuts down, during same PC power-on session, in order to find device it must be marked as forgotten in settings and make a full reconnection again. I have run troubleshooter, restarted Bluetooth services, running systems scans in the Commander and a bunch of other suggestions on this and other forums. The Bluettoh adaptor is Qualcomm Atheros AR3012 Bluetooth 4.0, PC is ASUS Transformer book TX300CA. But after reboot of the PC no devices can be found and a new reinstall must be done again. I have tried all versions of drivers from 2014 until the latest 2019 - and it doesnt matter which driver I reinstall after reboot, it works fine with any. I need to reinstall driver for my internal Bluetooth adaptor on each reboot of the laptop in order for the bluetooth to find my devices for connection. Problems occured after a complete reinstall of Windows 10 OS
