That CAT5e(nhanced) stuff has a bandwidth of 100Mbps though, so my poor results are not from using a dog of a cable. I'll try pulling the file back as you suggest, for hellery. >To your credit, your file was large enough to be a good test.

Well, I should then be grateful for the transfer rate that I am getting. What a hell of drop you got. As suggested, I'm going to try setting the media (in one NIC anyway) and both to full-duplex if my Compaq NIC can do it.
