This is almost certainly wrong for your hub. The speed problem is likely because you have a dual speed repeater. The 595 speed autosensing must be done by the driver. In order to not screw up 10baseT repeaters with 100baseTx link beat the driver first sets the speed to 10baseT and checks for link beat. If it finds 10baseT link beat it never tries 100baseTx. The solution is to set the speed to 100baseTx using a driver option. Read http://www.scyld.com/network/vortex.html The 3c595 is a very old card. You will get better performance from any modern card.
