PS3 LAN COD5 BLACK OPS?

This is the THIRD time I have asked about this...does anyone really know how to do this?? I have a router...two ps3's, two TV's, two copies of the game, so please no dumb answers like that. I know the gist of setting this up. The ps3's recognize they are on an active network. I DO NOT HAVE INTERNET SO DON'T REPLY WITH ANYTHING REGARDING IT!!!!!!! Both ps3's have firmware version 3.60. Our games will not appear on the LAN screen after we create them. WTF do we do to get this going??
