What I find more interesting is that you have collisions on both your LAN
and DMZ interfaces on the wrap board.

First thing I would try doing is changing the switch port your LAN interface
is plugged into and see if that makes any difference.

If it doesn't, try swapping the LAN and DMZ ports around. So reassign your
LAN to the DMZ interface and the DMZ to the LAN. See if the high collision
rate follows one particular port.
