Wireless ADSL Router - DSL-G604T Problems

[Louie2304]

Hi Guys, Just been given this router.

I can set it all up until it comes to checking the internet connection.

It verifies my IP address, but as soon as the internet connection is tested i get the following message;

"An error has occured during connection with the server. This is a DNS Error."

Does anyone know what this is, and what I can do to fix it.

Thanks.
