We just upgraded two days ago and as soon as we upgraded, the voice chat feature on the PS4 refuses to work (NAT type error). It worked on the lower grade plan we had when we were using our own router, but does not work with the new one.
We've tried opening ports, UPNP, and DMZ with no luck either on their own or in any combination. Why isn't it working and what can we do? The most we've gotten from tech support (e-mail) is to use our own router in conjunction with their equipment, but no info on how to set it up.
This is very frustrating as we upgraded to get a slightly better gaming experience and now we have essentially no gaming anymore.
