Heyho leude It is about the following I have a ps4 slim and have internet problems every evening, yes every evening in a period from 7 / 8pm to about 11 / midnight, I tried everything that can be used as a tip and trick, the DNS changed etc. And immediately.
I even switched to LAN and there's still the problem every evening, every time everyone gambles, except for me
If several gamble, then the WLAN becomes slower.
Unfortunately you have to have a good Wi-Fi to play in peace. Btw Ps4 is for couple games like (Fortnite) broke.
I have a 100k line, it shouldn't fail and I don't gamble over WLAN, but LAN and still it doesn't work
