Setting duplex and speed only works when the PC is connected
to a switch and not to a hub. Please note that when you are using
a switch, then setting the PC's NIC to fixed values also means
setting the switchport to fixed values. Otherwise you are very
likely to get a duplex mismatch between the switchport and the
NIC.

That does strike to me like a little odd. I just ftp'd a file of
493kB and my "Segments Sent" went up from 287721 to 288171. Which
sounds about right, considering there is also other traffic on this
PC. I saw "Segments Retransmitted" increase by only 1.
What do the "IPv4 Statistics" tell you when you look at them
just before and after the FTP upload? By how much does
"Output Requests" increase?
