CAX30 Drops Internet Connection
CAX30 modem/router with firmware 2.2.2.2 My CAX30 had been solid for about the past 2 1/2 months after a tech came out to install a splitter to reduce power levels. Before installing the splitter...
Power levels should follow that NG puts forth for there modems:

Looks like you found something that got the power with in those specs.
Come back and let us know if it works fully after a few days.
I've been monitoring upstream and downstream power levels after installing the downstream attenuator and they've remained within specs. I was hoping to get a solid week of use before marking this solved. Unfortunately, we had a power outage after 5 days and then Optimum had an unplanned outage today after 4 days of uptime. Each time I've rebooted the router, I get a Dynamic Range Window Violation warning, but that doesn't seem to affect the connection.
I did notice that the cable firmware version is 1.04.09 while Netgear has released 1.04.10. This might also be the source of this warning. Unfortunately, Optimum has to update the firmware and I'm not sure how far I would get trying to have them do the update despite the fact that Netgear claims to provide firmware updates to providers.
So rather than drag this out, I guess installing the downstream attentuator fixed the problem and I will mark this as solved (maybe).
Something to contact the ISP about to see if they can update the modem side FW if they have approved of the modem side FW.
Router side FW, NG has this for users to update too:
