Just as a suggestion, be sure your hub (especially) and switch ports are forced to half-duplex. While hubs should never negotiate full-duplex, I've seen it happen, and frankly I'm unaware of any successful full-duplex connections. It may actually work, but I've never seen it. Duplex mismatches can cause many errors, and impact performance dramatically. A very common symptom is failures under heavy network load. Very hard to diagnose.
