NETGEAR - Nighthawk CAX30 AX2700 Connection issues

I’ve owned a NetGear Nighthawk CAX-30 Modem/Router for 6 months. It’s been pretty much trouble-free during this time with only the occasional need to reboot because of video call freezing. Recently, I began to experience more significant problems with both wired (Smart TV) and wireless (iPad, iPhone) devices losing internet connection or having very long response times even after rebooting the modem/router. 

At this point, this will be my 4th return of this same Router, luckily I have a backup Router with the same config,  at one point I thought it might be a power surge, but I have a UPS on it so this can't be the issue, it seems to happen every six months or so

I have ring cameras and smart hubs. the cameras are via wifi, and the Ring Alarm base station and smart hubs are ethernets to the back of the Router, my Ring Alarm base station and hubs have lost connection, and other wifi devices are spotty, after several reboots, some of the ethernet devices, are connecting but intermittent, this is really weird because I have at least 3 Network switches in 3 rooms that are connected to the back of the Router and they are back up, but not the hub, and Ring Alarm base station, connected to the back of the Router also.

My backup Netgear Router is in place and all is normal, but this will suffer the same fate in six months, have a new Router replacement on the way.
