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. -- Keith Mitchell Email: kmitch@guru.org PGP key available upon request
