I've done a lot of searching about with no luck.
I use wireless as its impossible for me to run a cable about the house.
Anyway I've tried almost everything opening port forward for my ps4 tried DMZ and static IP address. And none of these worked, I've clicked on home network and even tried using a permanent IP and even that doesn't budge.
Any suggestions apart from a new router I want to try and get it to open if possible ?
