Same problems here. Bluetooth loses connection even if i dont leave the room. Same headset on my Iphone can be used in any room of the house. I have used 3 different Bluetooth dongles, 3 headsets and always the same issues. It's not as if bluetooth is new and nobody knows how to write code for it.
To rub salt into the wound this weeks Windows 10 upadate overwrote the drivers for my Realtek Audio. New MS Driver had no Stereo mix. Might not seem much but almost all of mr SDR Radio software uses Stereo Mix to send the Audio out.I wil just run around the web and find realtek drivers again. Why will they never learn to stop fixing things that are not broken.
