Ps4 pro disconnects from the network?

I've bought a Ps4 pro, but it always disconnects from the network so that the games and uptades are interrupted and it is reported as a DNS error, when I then in the settings the Internet connection Teste it runs again for a short time, in Sleep mode, it works fine

With the router everything fits 100%, because with the old ps4 everything runs, the signal strength amounts to 80%, I already tried everything, (dns changed, mtu changed, rout from switched on, ps4 to factory setting reset.

What else should I try?

Look if it is not maybe on the internet and not on the router or the console, lubricates with us lately in the village often times from the internet, because the console separates so synonymous of the network and usually it is directly afterwards synonymous again

As I said with the old ps4 everything works, so I think it's up to the pro

Using a LAN cable instead of Wi-Fi should resolve these issues.

Which router do you have?

Fritzbox 7430, must eig. Without cables fold, because it works well with the old ps4
