Sounds like a duplex mis-match, which is especially common with unmanaged switches. The problem is that the computer and switch don't agree whether their link is full duplex or half duplex. The result is undetected collisions which must be retransmitted via TCP timeouts instead of being retransmitted right away by the NICs. I'd suggest setting the duplex on the switch ports if possible and devices to see if a combination works better, I'm not sure about the Mac but you can get a list of media options on FreeBSD using "ifconfig -m".



I have tried that but the switch seems retarded :-) I can't force the switch to do anything... If I force the computers to 100/half the switch leds indicate 100/full. And if I force the computer to 100/full the switch detects 100/half... argh. When I set the computers to autodetect then both the computers and the switch seem to agree on 100/full (based on the ifconfig info and the leds on the switch). And they seem to work unless I want the Mac and the freebsd machines to talk to each other.


But... Something is definately wrong with the switch... Out of frustration I went out and picked up another ethernet switch from a different vendor (one of the new Nway ones that supports uplink detection too) and with that switch everything works as expected.... I had thought that I ruled out the switch since I tried two different ones with the same result (one was a 5 year old linksys 16 port switch and the other is about a year old mini 5 port linksys switch). Both were linksys switches though :-( The one I bought today that seems to work great is a netgear switch.... Hopefully its not all linksys switches since I was planning on getting one of the Linksys 8 port GE switches (I can get a really good deal on it). I guess i'll just have to try and see :-(

What i'd really like would be to get a 10/100/1000 managed switch but they want way too much for them to justify one for a home network :-(

Thanks.
