      I tried "no preference" and it works fine too.  Just the auto-negotiate that seems to give it fits.

      Thanks for the details.

        Yes, thanks for coming back. A couple of things confuse me here though. This seemed like a speed/duplex negotiation problem from the beginning which is why I suggested:
        @stephenw10:

        One thing you can try is forcing the speed on the pfSense NIC: http://doc.pfsense.org/index.php/Forcing_Interface_Speed_or_Duplex_Settings

        That should stop it trying to re-negotiate the connection continually.

        I was forgetting that there is a gui option for this in 2.1 at that point.  ::)

        However you then reported:
        @markn62:

        I tried "ifconfig em0 media 10baseT/UTP mediaopt full-duplex" at the command line, the message on my laptop said 10mbps for a couple seconds, then onto the ping-pong.

        It seems like that should have worked. Maybe an ifconfig down/up was required.  :-\

        Anyway glad you got it sorted, just trying to get a better idea of what happened.  :)

          Ya Steve, I didn't try long forcing 10m.  It may have needed an ifconfig down/up.  Though I was looking for a solution that didn't require anything manual after connection.  When I have to cold swap to/from current/backup router I don't want any issues adding to customer downtime.

          One more tidbit about how "no preference" would behave if I plugged into a 1G adapter.  Today I finally got brave enough to take the 2.0.3 box out of production and…cringe...swap in the 2.1 box.  I forgot my cablemodem has a 1G adapter.  Appears PfSense had no problem negotiating a link.  The swap-over took <5 seconds and no connections were lost.

          Happy days again...  8)
