Hi @Gary_Calega ----- Thank you for touching base with me and my sincerest apologies for the slow response here.
Continuing forward, based on your feedback it sounds like you are using a managed switch between your modem and the Nucleus. If this is indeed the case,
and you are making use of a managed switch, I would recommend enabling flow control on the device as we have seen a few issues crop up with these class of switches in the past ( Example: #1, #2, #3).
