Now, I cannot relate as I don't own a PS4, but since I have a Xbox One and they're about a wash, perhaps I could provide some information. Restart your router. This should always be the first step before doing any of the following. 1: The New Gen consoles all have a built-in Wi-Fi receiver, if you are experiencing issues, it could be defective. 2: This could be a ISP issue regarding wiring on your telephone line. Contact them and ask if there are any issues. Potential solutions and checks: 1: Plug your PS4 directly into the router using an Ethernet cable. Test the connection. If it works normally, it is likely the wifi receiver that is the issue. 2: Look in the manual provided by your ISP on how to configure your router for things like online games. I'm not an expert, but I hope some of this helps.
