Disconnection plague

Game mode:Co-op
Type of issue: Crash
SErver type: PVE
Region: North America
Hardware: Ps4

Bug Description:
None stop disconnection form a single player co-op server with a friend. They host and I join, I disconnect every 5-15 mins. Internet connection has no problems, they sit right next to me with the same internet.
Will this be fixed soon? Like I get bugs and this being a once in a blue moon thing but this has been a three day long problem.

Would be great if this stopped happening. Would be wonderful truly.
