I am having very similar problems as the guy in this thread
need help with setting up playstation network
My router is a d-link dir-655, signal strength is 100% i know how to get to router settings, but im having trouble with the whole DHCP, set up of a custom IP address just for the PS3 stuff. I (like nbventerprises, although not to put him down or anything) really dont know about all this ip, mac adress, subnet mask stuff so help would be very much appreciated. Thanks.
