update your firmware, follow the belkin procedure...
but if you tested your speed directly to the moden (without the router you can see this si not a belkin problem.
DNS: of course

I am talking about the dns from your rooter to the internet.
192.168.2.1 is not your real DNS.
Belkin router access is 192.168.2.1 (as far as I remenber) you have all information there.
But
What is your sat provider?
What is your plan?
When did you install your satellite system?
Thank you to give me the feeling I am a geek !
