Also, I had disabled my Antivirus as that had been suggested earlier, now for me it still worked after re-enabling Antivirus again as long as the QOS was done as mentioned! THANK YOU!

WOHOOOOOO!!!!! Thank you so much @Scoopien! Finally, I have waited 2 years almost for this and then it was as simple as removing the QOS high priority devices and set QOS as standard. Thank you,...
