Orbi V2.0.0.74 - iPhones constantly losing Internet connectivity (but not WiFi connectivity)

I actually decided to set up my google wifi 3 pack again, and allow it to run for a few days.    While it is not nearly as fast, it is STABLE and fast enough for all of my devices and normal usage.   I can now use all my devices and not worry about disconnects (wifi calls, netflix, skype, etc).    It bothers me that I am not reaching the full potential of my broadband capability but i am happy with stability over performance after the last few months with Orbi (first few months were great).     I am well past any return policy but will stick with google for the stability.    Maybe someday Orbi will have a stable firmware but not counting on it.
