Internet Connection Troubles?

[Matthew DB]

As the title suggest my home Internet connection is in trouble in that its saying my computer is connected, meanwhile my various programs (more than just the browser) are unable to connect to the intarweb. After checking the connection (the cables), turning off the firewall, and attempting to "repair" the connection, my computer still remains incapable to connect!!

What I'm overlooking and what can I do to fix the situation?

If any additional information is needed I'll add, and again thanks in advance for the answers!
Edit1: I believe I have a DSL connection (unsure w/ the computer lingo), and as previously mentioned it is a wired connection (not wireless) thx for the responses : )
