cg3000dv2 router/modem

What is the current firmware version for this Netgear router/modem? The Netgear site says the latest approved version for Cox is V3.01.16. That is not what I have. I have been having constant intermittent disconnects between the modem and the internet. At some point the original firmware was replaced by Cox (I don't know when, I was not informed) and was not experiencing this problem as far as I know. As I said, I don't know when the new Netgear Genie firmware was pushed down. No equipment or cabling changes have been made since before or after the condition appeared. This is very annoying. Netgear type N450 CG3000dv2 all in one router/modem.
