However, it is quite possible that it is infact 'downgrading' me to 10BaseT without me knowing it, although the LEDs would *seem* to indicate otherwise. The swithcing HUB is an Addtron. Perhaps when the budget permits, we will invest in a better one with monitoring capabilities, but for now I am stuck with it :-( The odd thing about the cable though is that once I reboot the FreeBSD box with the second cable, I am back to my good fast throughput without any interface errors on 200Mbytes of transfer. Then, again when I pull the cable out and plug back in the other, I am back to the same problem of slower throughput. The more I think about it, the more it feels like its the HUB trying to 'compensate', but alas, I cannot control that variable :( Is there anyway to get more stats out of the interface on the FreeBSD end of things that you or anyone knows of ? ---Mike ********************************************************************** Mike Tancsa (mike@sentex.net) * To do is to be -- Nietzsche Sentex Communications Corp, * To be is to do -- Sartre Cambridge, Ontario * Do be do be do -- Sinatra (http://www.sentex.net/~mdtancsa) * To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
