Please don't send me to the Community page. After uninstalling and reinstalling the radio, the computer now shows I have no Bluetooth at all. I already tried everything (Device Manager, etc.) I have Sony WF-1000XM3 earbuds. I'm running a 64-bit O/S. I'm running W10 version 21H1 (OS Build 19043.928)
I bought a dongle (USB 4.0). The file manager doesn't recognize the drive. It looks like my computer isn't granting permission to the flash drive, although the port works fine with everything else. When I view the properties on the Realtek Bluetooth 4.0 Adapter, the device status indicates it's working properly.
Should I start all the Bluetooth functions that are currently on manual and put them on automatic? I uploaded the Bluetooth Audio Receiver and cannot open a connection: those options are grayed out and it's on idle. Are there other troubleshooting options I can do to fix the problem in case this doesn't work?
