slow ftp transfers -->Re FTP problemThe 10Mbit is basically a data stream at that rate, while the 100Mbit uses encoding similar to the multi-bit per baud we first saw in old analog modems. The 100Mbit carried freqency is about 33MHz and we get 3 bits on each change of state. So you can see that in itself - a on/off carrier or constant carrier makes auto-sensing easier. It's the auto negotiating that seems to be the problem.

it can cache. This is a common misconception.
