Internet connection problem

Hi!

It has been quite a long time since my last post… The internet connection I have @home is now having mysterious problem. I can get the signal and it’s excellent. When I try to open a web site, my browser says no active connection. The same thing happens when I try to sign-in (using Yahoo Messenger and Trillian), and accessing Music Store (using iTunes). I try to use other connection (wireless internet @ campus) and it works well… The problem occurs when I’m using the internet connection @ home…

Strange… I don’t know how to fix it. Any idea?
