Hi alyandrob,
Thank you for reaching out to us in our community and welcome back, sorry to hear you are having issues with a slow connection which is effecting streaming, I have been able to locate your account with the details we have for you, I have done a full diagnostic and cannot see any issues other than a possible WIFI issue, looking at your devices there seems to be low WIFI, have you tried to run our Connect App.
The App allows you to locate and fix most WIFI issues, you can also run black spots and if needed you can order our Intelligent WIFI Pods, you can find out more around these here?
Regards
Paul.
