Wifi STOPS working after connected to bluetooth

So when I connect to bluetooth speaker, after some time my phone acts like its not connected to internet at all (instagram cant refresh, youtube tries to load video but cant, etc.), but I can see wifi indicator and in settings there are no problems shown, but if I have only bluetooth turned on and not connected to any device, my wifi will work like normal. I can get some time for wifi to work by turning it off and on again but time depends and I dont know on what.
