Windows 7: DNS server isn't responding, tried multiple things!

We have a linksys wireless internet connection at the house and everyones laptop is working except mine. Mine is connected but it says no internet access. I have tried switching the DNS server to public ones like Google, Norton, and a couple others but it keeps saying "dns server isnt responding". I have compared the settings on my laptop and another laptop that has internet under our linksys connection, to every detail and it's all basically the same.. What can I do?

If you can post a screen shot of your ipconfig/all it will give me a better idea of what might be causing this problem.

Hmm weird thing happened. Alright so now I have internet, other laptops are connected to linksys 3 and mine says linksys 20. But this has happened before where all of a sudden I lose the internet connection again. I am worried this won't last and I'll have the same problem again. How can I maintain this connection? I know the router is fine since all other laptops have internet, I just feel like I have to tweek something in the settings..
