was having an issue connected my PS4 to my new HUBtwo. We tried resetting both console and router, also put it on a ethernet cable and tried a master reset on the router as well.
Then I did a little further reading and come to the conclusion that the [voucher code removed] Buddy was blocking the TCP and UDP services.
Once I disconnected the buddy my ps4 instantly connected to the internet.
Thought i would share this incase anyone else is having that issue.
