And if anyone knows the right questions to ask or number to call for lower level tech support from Cox who can answer these types of questions.
There is no way to squeeze water from a stone. Cox Tier 1 read and work with a script now and are not technically trained or minded. You could ask for Tier 2 or Customer Advocacy Group(CAG) who might be able to see your firmware but updating is tricky. Not only must there be a updated and tested firmware available but there may also be procedural limitations of what Cox is allowed to do. Pick the wrong file and they could brick your modem.
I would start by bypassing your router and connecting direct to the modem and seeing if the issue occurs.
I just got some feedback from someone who tried to ask for Tier 2. Seems they are pushing Cox Complete Care(CCC) pretty hard for Tier 2/CAG escalations of non Cox hardware.
