This issue has gotten worse and worse over the past month or so. All the computers, Windows and Mac, Xbox live, Steam, and all other devices on the network have NO issues!! The PS4, however, almost 90% of the sessions established through PSN ends with a pop up message that states, your Multiplayer game session has disconnected. Before anyone tells me that I need to make sure that I'm forwarding the correct ports on my router, my PS4 is set up within a DMZ.. SONY should be ashamed for charging people money for this kind of service- PS+. It would be nice if someone over at Sony could explain to me why and how to fix it.
And I'm connected directly to the router, NOT WIFI
