Mac, vonage & Time Warner Help!!! now w/ added info!!!!

Reposting with better and more clear information.

I have a G4 laptop running System 10.3.9. I have an Airport Extreme with firmware 405.1. My cable modem is an RCA DCM425 (heres a link with a picture of it:

and my vonage box is linksys VOIP it is a broadband router with two phone ports (but i have one phone line running into it.) Here's a picture of that

Any advice on how to get my wireless to work. My cable modem is thru Time Warner it is hooked directly to my Vonage broadband router. I run my internet thru my Vonage broadband router as well. Whenever I try to plug my cable connection to my Airport Extreme that's where the trouble starts.

My computer sees my airport but whenever I try to log, I get a "page can't be found" alert. I also tried to plug in my modem directly into my cable hub and still the same thing so I don't think it's my Vonage acting up - it's my Warner box. My cable box only has one port so there is no way I can plug my internet directly into it since there won't be another port for the Vonage. I have to use my vonage box as the main hub.

Calls to the cable company offers no help so I'm hoping that I might find some answers here. Please let me know if I need to provide more information before I scrap the entire thing in a fit of disgust.
