I have tested 2 different hubs with the GE system and they both allow pinging from my Vista laptop to the GE backplane and proxy network.
The crossover cable is a last ditch effort to simplify my testing of why the Mac nic will not communicate with ANY device. A friend who does IT work suggests looking at the firewall. I found a firewall page but don't see anything turned on.
Does anyone know firewall locations in this beige mac G3? Could this be blocking my ping testing?
