In my experience, autonegotiation works great for speed, but for duplex it depends on what the other device is set to. If both devices are set to AUTO then it works If both devices are set to a fixed duplex then it works If one device is set to a fixed speed/duplex and the other is set to AUTO then the speed is negotiated properly, but the duplex is negotiated to half and if the fixed end is set to FULL then you have problems. -Brian

I heard 2 arguments and both seem valid. I find it a pain to have to go back in and set NIC speed on the switch and server/PC. Over wire builds suck (WDS) for speed etc. 1. Was that in old days the NIC chips had hard time negotiating and it is no longer needed, except that it would be good practice for servers which rarely change. 2. The other was that the auto-negotiate packets are 30% of the broadcast packets and by removing all doubt, they lessen the traffic. What exactly is the real story? I never had to set this before on the pc side of the LAN. TIA Luke L.
