Need help w/Samsung tv and router hook up.

Just bought a Samsung LCD TV. It has limited internet capability. Its connecting to the net through a usb plugged on its side and talking to my Dlink wireless router. I had to put info into the tv such as dns server, ip address and the likes. I had no idea where to get those numbers but remembered my Xbox 360 has those numbers stored which is the ones i used. Where these the correct numbers to use? The tv did the network check and got as far a gateway ping and stopped. I assume i have to open up my router's config and open ports or change firewall settings. Thats as far as i can get! I don't know what ports to open let alone how to do it. My netbook is hooking up to the router just fine so i know it works. I ran the software for the usb (its new) on my desk top which is plugged directly into the dlink router. Where do i go from here? Thanks!
