No access to PSN via the new router

I decided to update the router, the choice fell on ASUS RT-AC750. Plugged in, configured everything as it should, but now my PS4 refuses to connect to the Playstation Network. Tried via cable and via Wi-Fi, anyway. Service PSN checked, write works fine. Decided to make sure and distributed Wi-Fi from your phone, Sonya joy joined the service, then the problem is in the router. What you can do and where to dig?

PS Tried to put the latest firmware - the same result
