I had this problem when I got a new ps4 pro. I learned that you have to manually select a broadband width on the ps4. Or it might automatically switch between broadband widths in between games. 5.0 ghz to 2.4. So go into network settings select set up connection. Select your connection type. Then before selecting your WiFi. Press the options button and select either 5.0 ghz or 2.4 ghz. And the. Set up your WiFi normally after that. I’d recommend trying out both connection types. To see which is better.
