Hey
Don't know if it is a bug or something. Not a problem for me when I know the solution (or workaround (quit bluetoothctl)), so no need to dig deep into this, just information to others if there is an unstable wifi.
When bluetoothctl is executed as root, my wifi disconnects and reconnects repeatedly.
output from dmesg:
Took a screenshot of it, speed can bee seen down to the left, just above virtual desktops (Nätverk = Network). At the beginning started copy big file without bluetoothctl, then started bluetoothctl to find my bt-headset, and then quit bluetoothctl, which gave full wifi speed back.

Thank you all for a wounderful distribution.
