E-terminal Networking problem

I have an E-1061 terminal from Mitsubishi. I can use it to talk to a PC and even my PLC, but not through a hub. Anyone ever encounter this before? Any recommendations?

I can use the same hub to pass info from PC to PLC, so I know the hub is good.

double check the ethernet cable

a crossover cable is used between two computers, but a straight through cable is between a computer a hub.
