I would first eliminate the hard disk as a potential problem -- boot
into knoppix and try to transfer the large knoppix file from the CD to
another system.

I believe you'll still have the problem.  If so, start looking at NICs. 
Some older network cards, notably RealTek (RTL-8129 and family) were
real garbage.  They've gotten a lot better.

Personally, I suspect a network card.  If you have a known good system,
try a crossover cable directly to it.
