Help w/PS3 Internet set up

[BORICUACIVICR]

Ok here is the deal:

I bought a wireless N router (D-Link), hooked up to my comcast internet cable. Router is working perfect, 100% signal detected by the PS3.

But when trying set up and trying to connect this is what I get,

Obtain IP address: Succeeded
Internet Connection: Failed

An error occored during communication with server.
This is a DNS error.
(80710102)

Has this happened to any of you? What does it mean? How can I fix it?

I would be very greatful if anybody here can give me a hand with this.

thanks.

Thanks.
