Ubuntu:18.04
May laptop is connected to internet through WiFi
Then when I connect my bluetooth earphone and set the Sound profile to High Fidelity Playback(A2Dp Sink)
, the internet works fine
Results from speedtest.net with A2DP profile
The moment I switch to Headset Head Unit(HSP/HFP)
, the internet just stops working
As evident by https://i.stack.imgur.com/ue1Oh.png Speedtest downlaod fails

Edit 2: One thing that I have observed is that , the internet doesn't just stop working. It works for 5 seconds then it stops for another 5 seconds and this cycle continues
Maybe its because the bluetooth does not let wifi data passed for sometime or hogs 2.4Ghz all for itself

/etc/modprobe.d/blacklist-ath_pci.conf:# which ath5k cannot recover. To prevent this condition, stop

Edit 4
I deleted the /etc/modprobe.d/ath10k.conf
and /etc/modprobe.d/ath9k.conf
files as suggested by @Pilot6 but still same problem
lspci -knn | grep Net -A3; lsusb
terminal command.
