Network connection, but no connection to the Internet

I have had this problems for over a week. I have connected my xbox 360 Elite to my router by wire, it coonects to the router but it can not get any internet access. I can log on to my Xbox Live account but there is no internet access. I have resett my router
settings and xbox settings, i have tried wireless, but it just gives me the error message: 80151909

My mac adress is listed as allowed on the router, and NAT is open. The router works with phones and PC wired and wireless.

The last router update was 2 weeks before it stoped working, so it should not be the problem.

Problem connecting via a computer and ICS...

I got a connection to the network, but no connection to the internet.... I checked out the troubleshooting stuff in the guide... still no success.

thoughts??

 

How to get pc to recognize 360 for xbox live.

Ah, yes. I am familiar with internet connection sharing and network bridging. But my pc won't actually recognize my 360 as a network. I open my network connections and there is no port or connection for the game system. I have the internet source recognized,
but not the other half of the issue.
