Ps4 w lan connection breaks off irregularly?

My girlfriend's ps4 slim often breaks the wireless connection. We have 2 Playstation 4, one pro and one slim in the same room. The router is one room ahead. While my PS4 Pro does not have any problems with the Wi-Fi network, your connection problems are such that your ps4 simply turns off while playing games, and also flies out of spoken parties.

Maybe someone knows that problem and can help.

Had synonymous the same problem, depends on when you play, worried you a wireless amplifier, has worked for me again.

Play at irregular times,

but would be worth a try m thanks
