Internet crashes on the PS4?

Approx. Every 20 to 30 minutes the Internet breaks on the PS4 and then I have to go to the network settings, test the Internet connection and then it works again.

I don't want to keep doing that while I'm in a round at a game.

Strangely, that's only the case with my PS4. It works great with all other devices and my Wi-Fi is not that slow at all.

Do you have any idea why this could be and what you can do about it?

Do you have anything on the playsi? Or is there a lot of stuff around it? If there's something metallic, it can interfere with reception.

Change the frequency to 5 GHz, it is less prone to interference.

Nothing at all.
