Its FTP Performance under Win95/Linux is about 700-800KByte/sec against the ftp server connected to the same HUB. When I use this card on FreeBSD-3.1, it only performs in about 300KByte/sec for the same configuration. In addition, when I ping FreeBSD machine (allegro) on the same time pinging another machine (Sun Ultra-1), the RTTs against FreeBSD box showes larger variance (from 0.6ms upto 150ms). 'ifconfig xl0 media autoselect' produces following message.

You aren't running the latest release of FreeBSD and/or the latest xl driver, and you don't say what kind of hardware you have other than the fact that you have a 3c905B card. If you think that "Use Linux or Windows" is the proper fix for this, then go ahead and use them and leave us alone. Go try FreeBSD 3.2-RELEASE, or download the latest driver from http://www.freebsd.org/~wpaul/3Com/3.0. If you still have problems, submit another problem report because I am closing this one. -Bill >Unformatted:
