Orbi router solid magenta (not the satellite)

Thanks for your thoughts and the information.  I am still having some drops in hand-off and can't  accept that.  The only (verizon) cell tower available is across a river in an adjoining State.  Considering that, it does pretty well - but not good enough.  I have had drops with the Orbi but  since they're occasional I keep thinking I just have to move that Satellite two inches....  I'm using the router and two satellites (router in the middle) in access mode connected to Fios router. 

I've noticed my phone reporting it's on 2.4 and at another time it's on 5 which supports your comment about the bands stepping on each other.  I'm going to disable MuMimo and Beamforming in the hopes of having that stop the occasional drops.  But I feel really uneasy about Netgear's commitment.

I can return the whole thing to Amazon.  Given the expense and questionable performance of the router and two satellites, spending a bit more doesn't seem like the most important issue.  I need something that will get through thick walls AND will not drop wifi cell calls as I move around the space.  Plume?  Eero?  or  any other suggestions?
