Got the new BT smarthub 2, and well, once again it doesn't offer QoS for it (why?!!) and basically anytime my lass wants to watch her vampire shite on NOW TV etc. the d/l speed and latency on my wired PS4 takes a massive hit. Basically instead of buying a whole independent router is there such a thing that solely does the QoS thing that I can somehow connect to the BT Hub? If not is there anyway to sort of replicate QoS on it?
