"network not responding"spam Connection issues with solo play but fine when playing coop

[(PSN)aim342743]

I am having issues with this since last week ever since i downloaded the war within i can't play solo or i will get this network not responding spam and it messes up my psn also two other guys i talked with said that they have the same issue. Solo play is less demanding yet it gives connection issues yet coop is more demanding and i have played with a full lobby with no issues.Is this something to do with the games servers seems like it I need help with this.If DE is reading please fix this.FYI I am able to download games overnight so this isnt my internet because when i play solo it immediately gives me network not reponding.
