I have made some tests with a cable between a Intel Pro 100Mbit card and the Rhine II card:
100Mbit Full-duplex = No errors,speed ok.
100Mbit half-duplex = No errors,speed ok.
10Mbit Full-duplex = No errors,speed terrible around 50Kbyte/s
10Mbit half-duplex = No errors,speed ok.

So probably is the Rhine II card very sensitive to cheap Hubs and switches?
