Un-routed

I bought a new wireless router today. It still doesn’t work. I can get online only on the main computer, and only when the cable modem is connected directly to the computer.

I’m still hopeful I can figure this out, but the Linksys website isn’t much help, and their forums are an overload of information that might be of us, if only I could find and decipher it.

If anyone could steer me in the right direction… It’s a Linksys Wireless-G broadband router, WRT54G. When I run the set-up, I get either “new router not detected” or “no internet connection detected.”
