    We have just started receiving Dell's new Optiplex 755 model at work which comes with a new Intel NIC, the 82566DM-2. In Speed and Duplex settings, we now have to "Auto" options, Auto-Negotiate and Auto-Detect.

    Before we used to set NIC speed to "Auto" on older NICs such as Broadcom NetXtreme, and the Intel Pro 100 or 1000 NIC which was being shipped but now we have this new one, does anyone know the difference between Auto-Negotiate and Auto-Detect, and which one will be the same settings as "Auto" on the older NICs.

    Any help would be much appreciated.

    Regards,
    Alex

    auto negotiate is for speed settings (10/100/1000)
    auto detect usually refers to the ability of the NIC to detect and adapt to the cable type (no need to worry about straight thru or crossover cables)

    cheers for your help.

    We use the auto setting for speed issues, and to match port speeds, as cabling doesn't come into it. So I guess its the auto-negotiate that we need to use as the speed and duplex setting on the new NICs

    thanks again
