Full duplex is 'ifconfig ed0 media 100baseTX mediaopt full-duplex'. If you still want to experiment with speed: 'ifconfig ed0 media 10baseT/UTP' (assuming UTP wiring rather than coax). -Warren Block * Rapid City, South Dakota USA To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
