Exactly Bob, and this was why Andrew, I suggested using the DOS utility to force half-duplex, full duplex with testing performed each time.
And as far as the networking terms go, errors = bad. Pretty simple. As you can see with your test, every one of those errors are overruns. 3: eth0: <BROADCAST,MULTICAST,NOTRAILERS,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:20:af:17:57:b2 brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 741077003 1773743 18161 0 18161 0 TX: bytes packets errors dropped carrier collsns 438580149 852431 0 0 219 2150 4: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:20:af:3f:53:d4 brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped overrun mcast 440479032 855735 4271 0 4271 0 TX: bytes packets errors dropped carrier collsns 680103683 783492 0 0 0 4193 Andrew, you've spent this much time with this, what's another 20 minutes with the DOS utility (which was designed for that card) to change the settings?
