My suggestions, in relevant order.

1: use the debug command in ifconfig and see if you get any error
messages.
2: manually set the duplex on the interface(s) to half-duplex and see if
that doesn't fix the problem.  If it does, then either the port on the
switch/hub isn't set to or doesn't support full duplex.  Actually, before
you change the duplex, check hub/switch ports for excessive collisions.
3: check the physical layer and replace the cables.
