Yes, I'm talking about datagram collisions. Regardless of how my machines acquire their IP addresses (manually or DHCP), the problem G3s still have data transfer problems. They'll play nice with a router for Internet access or my LaserWriter 630, but as soon as I try to do a file transfer from a 100bT machine to the 10bT G3, nothing but collisions. The files download eventually, but it takes forever because the same packets keep having to be sent over and over again on account of the collisions.
