Orbi disconnecting continously

Hello,

So I have been trying to solve the same issue for days now. My current setup involves an ethernet connected from my Fios ONT box into their Fios router. This router has the wireless disabled but is acting as the router. There is ethernet from the Fios router into a Cujo box (more on that later). Then from the Cujo to the Orbi. The Cujo was in bridge mode. I have my Orbi set as an AP. I have my main Orbi in my living room, and the second upstaires in my office. I am terrible at measuring distance, but they aren't that far apart. Also I am upgraded to the latest firmware on both Orbis.

When I first got the unit it was working great. I would say this lasted for roughly a month or two. As of last week (or around there) we started to notice a lot more issues with our internet slowing down and frequent disconnects. We have 150 up/down so the speed from the ISP isn't the issue. Also, when I say slow down I am referring not really to file download speeds but rather to web pages loading, iPhone app's loading info (for example BestBuy loading their products or perform a search, Instagram loading pictures), and streaming tv/movie frequent buffering.

The other issue we were/are having (at the same time) is with our Dropcam. Frequently we would get the notification that our camera was offline and then would return backonline very shortly after. After reading more on the forums here we took the advice and turned off Beamforming and MIMO and it solved that issue, but also took away functionality...

Now, for the long troubleshooting tests we have taken. We have tried almost every Orbi software configuration we could think of. We also tried, and still have, removing the Cujo from the setup to rule that out. When we removed it the issues were still there and exactly the same. We have left it removed to keep it out of the trouble equation. We have tried with beamforming and MIMO on, turning one off and the leaving the other on, to leaving them both off. Also we would reboot both the Orbi and Fios router inbetween each setting change. Next I tried disabling the 2.4ghz radio and pushing everything onto the 5ghz thinking maybe there was a problem with the Orbi assigning bands, but the problem presisted. I reenabled the 2.4 ghz and unplugged our satellite Orbi. This happened later last night and as of so far it seemed stable, granted I am not home yet to get a true feeling for it.

So by my wonky troubleshooting methods it would seem that there is a problem with the backhaul betwee the two Orbis. If there is beta software available I would LOVE to try it out and test out whoever possible. If anyone has any other solutions please please let me know. The only other thing I really haven't tried is removing the Fios router from the equation, but that is only because my ONT is outside and I would have to fish cable through and terminate ends as an RJ45 won't fit through the hole.
