cisco 851 - DNS problem

[736xl]

Anyone can shade some light? I Can see the cox network fine but no DNS. name-server is correct. What am I missing? I noticed that cox box receives a 192.168.100.1 temporary Ip. After about 20 sec, it turns into a different ip address i.e. 72.204.234.166. Any help would be greatly appreciated.

Thanks

Not sure why but I think the setup was correct. I just needed to wait a bit longer. I am able to get to the internet. However, my last problem is it is really slow and not sure why. I have a linksys router and it flies.

Perhaps I can still get some answers why and how the broadband should be configured.

Again, help would be greatly appreciated.

So the problem was trying to get out to the internet, and NOT the wrong DNS server???
