No login wireless in Playstation 4 Network with standaard settings in ORBI RBK53, PLEASE HELP SIMPLY

The playstation 4 can't login with WIFI, no NAT it says. The standard settings : I have noting changed in setting. RBK53 installed with Phone. Was fine! Everything worked ALSO the playstation! And now it's not oke. When I put a cable in the ORBI router it works good! But with wifi.... NO. The PS4 gets indeed the IP adres but no NAT. 

Ziggo (dutch provider) modem in Bridge, Router RBK53, Iphone, iPad, NAS, Hue etc works fine. I'm a little affraid if I ruin the other setting. So it must be a setting in the Netgear RBK53 router? Or perhaps an update from PS4 that could be changed something...? Can you give me an advice? I read a lot of things but what is the best I can do? It looks like that there is a kind of port closed…? Thanks for the repsonse….! And I hope you have a solution :)

I'm sorry but I dont know what you mean with: "What FW is currently loaded? What is the Mfr and model# of the ISP modem the NG router is connected too? Is this question answered…?
