I am reformatting an old indigo iMac G3 for a friend (so she can use the WWW). However, when I connect the iMac to mine (G4) via a network cable, I can't connect to the net to perform software updates or using IE. It seems to be picking up my IP address in Network settings.. and the light on my modem is flickering above the port it's connected to.. any ideas? could it be a network card issue? your advice is appreciated!
