Internet connection

You're going to need to explain the problem in a bit more detail. To start with:

1. Is your PS4 connected through ethernet (wired) or wireless?
2. When are you getting kicked off? Is it always at the same point?
3. Is it just one game or all?
4. Which game(s)?
5. When did the problem start?
6. Are any other devices in your home affected? (PC, cells, tablets, Optik tv, etc.)
