[Wlug] RedHat 9 Network Problem

I just replaced Windows XP with RedHat 9 on one of my machines at home. My problem is that I can't connect to the network. If I specify DHCP and then try to connect I don't get any responses from my DHCP server and 'eth0' won't activate. If I specify a static IP address (i.e. 192.168.1.2) then 'eth0' will activate but I still can't get out on the network, event to ping. My network configuration consists of a Netgear 10/100 Wireless Router connected to a Cable Modem, with a Linksys Router/Switch to the Netgear Router to expand my ports. I've been running fine from all my XP Desktops through this configuration using DHCP. Any ideas would be appreciated.
