Orbi RBR850 and RBS850 Frequently Disconnects/Disappears

I am experiencing the same issues.  I too have frequent disconnects from my devices, wired and wireless. I have to power cycle modem (CM1000), then ORBI router multiple times per day, which is usually just a temporary fix.  Devices will show I am connected to ORBI, along with a strong signal, but I am unable to access the internet.  The last tech told me I needed to do factory reset.  Luckily I found that MANY people, including yourself, are experiencing the same issues.  I work from home and don't have time to BETA test their very $$ router.  Will be returning unit.  Hope you have better luck than I do with this...ugh.
