Netgear CM500 T3 or T4 Timeouts

I'm new to the forums here. I originally had the 200 Mbps Down/10 Mbps Up internet plan, but got upgraded to the 400 Mbps Down tier last October. Since my Netgear CM500 modem can only handle up to 300 Mbps, I downgraded back to the plan I had before. Speeds are consistently around 238 Mbps down/12 Mbps up, occasionally crossing above 240 Mbps. Lately, I seem to be having some issues, though. With random dropouts, disconnects, having to frequently reboot, the MyAccount app stating it can't connect to or send a signal to the router, etc. I recently disconnected the modem, unplugging all the cables (coax, ethernet, power), and reconnected them again as a result of these ongoing issues. 

Regarding my personal set up, I have the modem directly connected via coax cable to the wall outlet. There are no splitters between the wall and the modem. I also have a TP-Link AC2300 wifi router connected to the modem. Btw, the modem has the latest firmware: V1.01.14 as well as the router, too. When I accessed the Netgear gateway for the modem, I saw some "critical" errors and such in the log:

From a quick search on the forums, it seems others had similar issues with this router. Is there anything I can do on my end, or should I just go ahead and give tech support a call, possibly to set up an appointment for a technician to come out? Lastly, there were quite a few outages in our subdivision community lately as I noted a presence of Xfinity trucks out and about. Not sure if they were upgrading or repairing the current infrastructure. 

Thanks!
