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 see my modem has 2 ethernet ports - does Cox allow me to connect both of them and get different MAC addresses? Thinking I could connect my 1 computer directly to modem and rest of system through router to the other port. Then I can see if issue happens on that one computer anymore to resolve if it's modem or Cox issue vs router issue. I did update my router firmware though.

No. The two ethernet connections are for setting up LAG for faster then 1Gbps speed. See here for more info. In order to use each connection to a separate device you would need Cox Business for more then 1 public IP address. Good idea though.
There was a time when residential customer could get 2 IP addresses, the second port would allow for a second router. Also business customers CAN get 2 IP addresses, and can use both ports.
Wasn't it called Multiple Computer Access(MCA) or something? My memory is a little hazy. It cost extra money right?
