Let me re-word my question; looking it over, I realized that it made no sense:

As you know, I have an iMac G3. I keep it upstairs. Downstairs, I have a Windows PC. And (as I failed to mention before) it has a 2-wire router connected to it. But the iMac doesn't.

What is the most effective way for me to connect the iMac to the Internet, with what I have listed above?

If that isn't sufficient, what else do I need?

Thanks,
