Mac/PC wireless router problem

At home, I have a Mac G3 desktop computer
connected to a cable modem. I just purchased
a Sony Vaio notebook for work, and want to
use it wirelessly at home to share the modem
connection. I got a NetGear WGR614 v5
wireless router, followed the installation
guide, but within 5 seconds of finishing
startup, the Mac freezes up. The NetGear
Resource CD doesn’t work properly, either.
When I plug the modem cable directly into the
Sony notebook, it connects instantly with the
Internet. Any help greatly appreciated!!!
