I have a cable internet connection going into a cable modem. The modem connects to a _hub_ with an ethernet cable. Out of the hub, I have two ethernet cables going into two different iMacs. I am trying to share via "built-in ethernet." The primary computer connects without a problem. The seconday computer doesn't seem to recognize the local network and tries to connect directly through the cable modem. I also can't get it to recognize the printer that the other computer is sharing.
Does anyone know what I'm doing wrong? Do you have to have firewire or AirPort to set up a shared connection? I thought the hub would be enough.
Please treat me like an idiot and go slow ;-).
I sincerely appreciate your help.
