Help connecting RH Linux 9.0

Hi everyone,
I was just wondering if someone knows how to connect Red Hat Linux 9.0 to the internet using Optimum Online which is my cable ISP. I have both, XP and RH, and I want to make my external modem connected through ethernet to my computer work for RH just as it does with XP.
Several weeks ago I installed SuSe and it worked wonderfully, but I don't understand why it doesn't work with RH. I already tried the Internet Connection Wizard, but it doesn't seem to recognize my "Broadcom 440X 10/100 Integrated Controller" Network adapter.
Any suggestions??

Thank you very much...
