C7800 Netgear Firmware Version V3.01.40

I've replaced my equipment in December and have had intermittent connectivity issues since. Netgear shows the recommended Firmware revision for this devices on the COX network is 3.01.38. I am running 3.01.40 and am receiving no help on the discrepancy during any of the many chat sessions I've worked during outages. They just say they are pushed down periodically and basically, there is nothing I can do. Netgear support provides the same answers and I feel really tossed around between two companies.

I would like a straight answer on why I'm not matching the recommended version as shown on the updated document from 2/17/21 (link below). I've also attached the signal and connection information I've seen requested on similar posts.
