My recent experience might not help here, but might help others in similar situations, so here's what I discovered: I had just 1 or 2K bytes/sec on an "rl" NIC using 4.0, 'ifconfig -a' reported the rl0 was in "autoselect" mode, I guessed the NIC was maybe switching modes & losing traffic, so I added "media 10baseT/UTP" to ifconfig_rl0 in /etc/rc.conf, and now get normal performance on 10 Mb/s twisted ethernet. BTW the slow performance of "autoselect" was seen on several (though I did not try all 4 combinations) of { a 4 wire cable with no screen : a screened [maybe 8wire] } & { to a hub : direct via crossover adapter to another FreeBSD 4.0-RELEASE "ep" running on a pcmcia 3com 3c589c }. Maybe your chipset supports media selection ? maybe as well as AUI/BNC settings, you might also have a 3rd auto detect option selected ? that's running slow ? if so try changing it explicitly to AUI using the 3 com software, or try aprox "ifconfig ep0 media 10base5/AUI" Long shots, agreed, maybe worth the try though. You might also ask your friends if they know anyone with an ethernet analysis box. Good Luck.
