The Static DHCP table is where you would reserve a specific IP address for the PlayStation 3, which was one of my suggestions to you. And yes, having the IP of the router in the secondary DNS server section would not help things either.
The fix was made when you added in that bit of information the PS3 needed- sometimes the easy settings don't quite cut it for grabbing the information it needs.
Afraid I don't get much time for online play between doing this and work- at any rate i suck at the squad shooters. Just not my thing.
