Recent disconnects with my Orbi RBR50, have to unplug power to get running

Hello everyone, first time posting here. I am sure this has been mentioned in the past but I did not see any recent posts on the subject. I have a Orbi RBR50 system, router and one satellite. All connected to my cox modem Arris SBG 6787. I have the current firmware of V2.7.2.104 however since this update I have noticed my wifi has been dropping or disconnecting where my current solution has been to disconnect the router from power for over 15 seconds and then everything works back up with lights and then it is all working. I assume it is just the Orbi cause not of my wifi devices seem to want to work and I have trouble seeing the system through the app unless not through wifi (when I am having the disconnect issue). My imac is wired connected to the modem and works fine when this issue is going on. Some help or suggestions would be appreciated, this has happened over 4 times in a short span of under 2 weeks, I think. Oh when I do suffer the non working wifi there are not lights on the Orbis, I only know it is not working when my devices seem to be not connecting, but the wifi bar show up on the iphone and ipad however nothing loads. What step can I take or what further info can I provide to solve this inconvience. Thank you.
