The PS3 Man (wii rocks too, and xbox 360)

Lately, I have been attempting to connect my Playstation 3 online. I have a buffalo router which allows me to have 4 LAN connections. Whenever I try connect to the Ps3 network, it successfully obtains my IP but fails in finding the connection, error (80710102) something to do the DNS. So if anyone is using a wired connection could u please help me, or if u know comment me on my page. Ur help will be highly appreciated.

PS3 Rocks
