Orbi RBR50 router randomly disconnects/blocks internet for the whole network.

Ha.......appreciate the inquiry. But have seen all of this before.   I can summarize.  I have tried about 4 or 5 different firmwares, moving back and forth.......on router and stellite.  Factory resets  before and after each re-load.    I have used debug config to disable upgrade, and collect logs.  I have tried every iteration of every setting there is on every menu, and nothing has worked.  without fail, I drop internet on all connections (wired and wifi) several times a day, and it lasts anywhere from 10 seconds to a couple minutes.   It's very strange. 

I collected those timestamps and contacted my ISP provide (Spectrum Cable), and asked them to view my cable modem status and logging.  They ssaid there were no interuptions to my signal and no ISP issues during these times of disconnect.  I can confirm also that I connected directly to modem with a laptop for a couple hours and did not experience and discos either. 

As of last night, I did a final factory reset, and allowed Orbi to just use the default SSID and password, and I left a work VPN connected all night.......as of this morning I see no reconnect messages for last 8 hours.  

If this ends up being the resolution.....I am truly mystified.  A $200 wifi setup that can't handle a name/password change?   Ridiculous.  

I can live with this being the resolution, but I can't believe all the time and effort wasted on config and firmware upgrades, that this is still an issue with the system.  

I would have to think that there is some internal setting that tries to reset itself or reference the factory default wifi setting, and that causes a hiccup every so often?   If so, come on Netgear, this should be fixable.........
