JLQ:

nightcat did give the right advice, it sounds like. Of course, we won't know until you try it and reply, but yes, while with some devices and configurations you could use your ISP dns servers hard coded, it is possible this will cause problems with your router not liking to NAT a service that it thinks it should be providing. there are a LOT of variables listed here, and IknowNot summed it up pretty nicely...try to reply to specific points or queries we've made in trying to assist you, and try to provide as much info as possible. Otherwise we get a very disjointed conversation...as we've started out with.

I would suggest that you try to use the Static DHCP option of your router, since you now are abble to access internet resources. This is a much more elegant solution, and means your system will be ready to go for most other locations, if you take the laptop out of the house (do you use any public hotspots? They are almost ALL set for DHCP.)

Let us know how it goes.
