RBR750 mesh system constantly dropping Wifi

I don't see a recent response to this - hoping this means that things have settled down for you are are now working.

In case they are not, I see that you responded that you have a "Spectrum D3.1 eMTA, DOCSIS 3.1 Advanced Voice Modem. ".   That's a pretty generic description, but I believe I used to get the same description when I looked - and I actually had something like a Hitron E31T2V1 or E31U2V1 or something in that E31x2V1 model line.

Are you receiving your phone service through the same modem?  While not everyone who gets this modem from Spectrum also gets voice service - some do.   If you are - whenever you lose your internet/wifi -   pick up the phone and see if you have phone service or if you have NO dial tone.    If you have no dial tone at the same time, then it's your MODEM silently rebooting/resetting, not the Orbi.    

I mention this because I lived through this for months with Spectrum and that modem.   When I called - they always said that there is no issue - although there was.   It took a while before I was finally able to figure it out - when no dial tone - the modem was rebooting - although all of the lights didn't go out like a normal reboot.  It started happening about a year after that modem was put into place.

If you find this is happening - go to the Spectrum store and get a new modem.    I went from the E31U2V1  (Ubee manufactured) to the E31T2V1 (Techniciolor manufactured) - and have been rock solid ever since.  Hoping the "T" version doesn't crap out after a year like the "U" version did.
