RBS750 Not "Meshing"

V7.2.6.31_5.0.24  I think this is the most current version.

Your suggestion worked, but not in the way I expected.  I moved the closer RBS750 about 5 feet farther from the router, which put in the same room as the further RBS750.  I unplugged the further and plugged it back in after the nearer booted up. The nearer RBS750 showed a "poor" connection to the router (in the admin app - which I have to say is handier than the Orbi app.).  But the further connected to yet another RBS750 that I didn't previously mention.  At that time I had not added it to the system.  The third RBS750 is connected to the router via wire t get it configured.  Its in the same room as the router, but about 7 feet lower.  That satellite is what the further connected to with a "good" connection.  So weird.  But there is a lot of ductwork and pipes in the basement ceiling.  I think the angle of the backhaul transmission from the further satellite to the 3rd satellite gets under the obstacles.  I have some placement experimentation to do. 

Thank you for your help.
