You might just need to do a > "ifconfig fxp0 mediaopt full-duplex" Note that full-duplex can also SLOW your network down. I don't understand this, and am too looking for answers. However, I switched a 100+ to full-duplex and went from 10Mbps -> 10bps transfer rates to a sparc/sol2.5 box on 10baseT LAN (though connections off the LAN were normal). Clearly some care needs to be taken in how to configure this card. -- Steve Farrell To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
