I recently changed from Windows 10 to Ubuntu 18.04. I'm now facing a strange problem that I dont know how to deal with.
Downloading works perfectly until I start listening to some song on Spotify using Bluetooth headphones. When I click play, instantly my download rate goes to zero (or near it).
Here is the output of lspci -knn | grep Net -A3; lsusb:
