Your correct with your understanding of our setup, I also note on our NPE-G1 that the onboard GIGE interface will auto-negotiation and I do see the flow control is not supported via the other side (Comcast) but as soon as I refresh and view the GIG# interface again I note that flow control is

A couple of questions - 1) What flavor of NPE are you using? NPE-G1 2) Is the GigE interface on the NPE-G1/G2 OR is this a PA? 3) Is the FaE ethernet interface that you appear to be connecting your laptop to, on a separate PA in chassis? Laptop connected directly to router via slot 4
