Network card -- not found

[Joshua Foster]

I cannot get my ethernet card working.  During installation, I was asked for my IP address, netmask, and gateway, which I thought meant that my card was recognized.  But I can't ping anyone but myself.  I looked in the configuration file and the only two devices configured are "lo" and "sit0".  Do I need a specific driver for the card?  It's a Linksys Network Everywhere NC100 v2.1.  Where do I find a driver?   Thanks,   Josh
