I've been having problems since July last year, when everything that used to work no longer works.
My nat used to register as open on every game I had. Now it's always moderate or strict without my changing anything, even though in the internet connection settings it says Nat type 2.
I have UPNP enabled, my ps3 is set on DMZ.
I'm using a Motorola Surfboard Wifi Modem that acts as a modem/router in one. I've had this since January of last year so I know it's not the modem.
I'm also using a Wired connection. And there are no other devices on the network while I'm trying to connect.
Can anyone help me fix this so I can play my games online again without constant DC's and interruptions?
