Playstaion 3 and buffalo Nfiniti wireless-N-router model WHR-G300N

I’m having trouble setting up my PS3 wirelessy to my buffalo router. I succeeded in getting my sony viavo fw550f to run wirelessy. I called tech support at buffalo and sony but no luck still. All the info seems to be showing up O.K. on ps3s screen. The only thing I haven’t tried is to enable the AOSS sync button on the buffalo,the buffalo tech said I don’t need it. But it seems odd that the ps3s screen says to push that button on the buffalo. Ps3s problem is it" can’t connect to the server", and then gives me an error #. Can anybody please help!?.:sad:
