Internet Connection Problem

There seems to be a problem connecting to my wireless internet, it connects to the internet but then does not load any web pages or allow msn messenger to connect. When I hit troubleshoot in messenger it says there is a problems with DNS and key ports... I have not changed anyrthing on my computer so i don't know what the problem could be. Could it be a problem with my ISP and not my computer/router?

 

short answer? definately.
long answer:
Make sure, AND MAKE SURE you actually have internet connection. just because your IE is loading, it does not mean you have the internet connection. You can disable all your networking and IE will still load.
Call your isp and check first.
