It's a weird situation example on PS4 playing any game the game disconnects "Network Error" however if I go to the dashboard then select browser I can access the internet so i'm not fully disconnected.
Anyway yes to your question I have tried everything I know of as well when wired I still get above average jitter and now down to my last resort. That is a new PS4 the second 1 I have bought along with new monitor new cables and second hub 2 engineers so only a new router to go. I feel it won't make much difference but hey ho lets see.
