How to force quit an application.

I am having trouble getting the airport extreme working.  It keeps telling me I have a self assigned ip address and can't connect.  Do I need to set up a phone session to fix?

It sounds like your modem is not providing a connection to the router so the router is making it's own IP address up.  Anytime you see an IP address starting with 169.254.... that means you aren't getting a connection to the internet.
