I have a possibly related problem. I have never been able to get one laptop I
have to download at past 40kb/s from any of my FreeBSD machines when the
laptop card links at 100Mb/s. The NIC on the FreeBSD server can be SMC or
Intel, and in between a hub or a switch. The laptop communicated just fine at
10 or 100Mb/s speeds with any windows machine I have. The laptop runs 98se and
the FreeeBSD servers have had 4.0 to the latelst 4.3 stable. The laptop NICs
I've tried are the Intel labeled 10/100 Xircom card with dongle and I think a
3cx575? 10/100 X-Jack card. Again, the laptop only has problems with FreeBSD.
