@wsaca Well, this is the last Router I buy from TP-Link, this function is obvious for a gamer router, and for all other routers !!!  QOS is not working very well, I tried almost everything without success.  If the Xbox update a game, everybody in the house will have issues with their access, on YouTube or whatever, and the only way this router allow is to prioritize all computer but not the Xbox ???? That's crazy.  Also, the famous bug that the router need to be restarted once a day to improve overall download bandwidth, ridiculous.  Sorry to post this kind of message, but It's been years since this router have been released, no more excuse !
