RBR20 continues to shut off

[HRH60]

I am not at all techie. I have a NETGEAR cable modem and an RBR20 Orbi Wi-Fi Mesh router. My setup has worked fine for the past 1 1/2 years. For the past two weeks, the Wi-Fi has been going down once or twice every day. If I unplug the NETGEAR cable modem and Orbi Wi-Fi router and plug them back in, the system works again for another half day or full day. I feel like the problem must be in the Orbi Wi-Fi as the problem does not impact my Comcast TV signal. Does anybody have any suggestion as to how I might be able to fix this frustrating problem?  Please dumb down any answers. 

thanks.

Netgear engineers have communicated that there is a bug in the Traffic Meter feature which was triggered by Daylight Saving Time.

The "fix" is to use the Orbi web interface, Advanced Tab, Advanced Settings, Traffic Meter (toward the bottom of the menu) and clear the box "Enable Traffic Meter."
