Orbi AX4200 Router/Modem Combi keeps disconnecting daily

I've been researching this for weeks and still can't seem to find a solution. We bought this router/modem at Best Buy and it worked for about 10 days until we started having daily disconnects. We had to restart the Orbi in order to get it back. Of course we missed the Best Buy 2 week return date and they wouldn't budge on it or even give us store credit on the 21st day. Very frustrating and will probably cost them my future business. 

Netgear don't even get me started they are ABSOLUTLEY the worst I hate em. We go through the same troubleshooting over and over again and they won't send us a new unit or refund our money. We have called them at least a half dozen times. Nobody cares about the customer anymore [Edited: "Inflammatory/Language"]

We spent $500 on this unit and when it was on and working its fantastic but it keeps disconnecting. Does anyone know of a solution that works?

Thank you
