I started seeing issues playing on my ps4 a few months back, sometime in december. I can't say for sure which firmware it was but i think starting from 380.64 and forward i was getting major lag on any game on the ps4. I've see this issue once before back when i upgraded to a new firmware back in black ops 3 last year probably towards the end of the games life. I switched back to a previous firmware and everything was back to normal. i also recently went from the N66U to the AC68U and nothing had changed in regards to the connection on the ps4.
So i think the issue started for me back on 380.64 and every firmware since. I've done all the factory default changes, etc. I am currently back on 380.63_2 and it is working perfect again. I enjoy these firmwares and this doesn't change my mind in any way on how great these are. I just wanted to mention it on here. And if anyone is having any issues gaming you could give it a try
