RBE971 Router and 6 RBE970 satellites

My wi-fi covers approximately 24,000+ square feet. All on ground level. My placement of 971 Orbi Router and all 6 satellites, gives me excellent wireless coverage throughout my property without any dead spots. The issue is that I discovered when Orbi 971 router is rebooted, it does not recognize the network map and all attached devices, including the Satellites. Presently, I still have excellent coverage with 1 gigabit speeds from the router and each satellite, but 10 of my connected devices (all online) and all 6 satellites show as disconnected. This Orbi 970 setup replaced Orbi 850 with 6 satellites which worked great for several years until it failed
