ORBI AC3000: Satelitte looses connection but does not reconnect

Router and Satelites run with Firmware V2.7.2.102

> What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
I can't proivde this info currently. The installation/buliding is 3 h travel away, that's my problem that I have troubles in this remote location 

> What is the size of your home? Sq Ft? What is the distance between the router and 📡 satellite(s)? 
It's a large multistory home (wood/concrete):

- Router on base floor

- Sat.1 on the first floor, about 10..12 m (32..35 ft)  "bee line" distance (Signal Fair  79 dBm)
- Sat 2 on the third floor, about 11 m (32 ft) "bee line" from Sat 1 ( (Signal Fair  79 dBm, sometimes I see "poor")£

The question remains:

1. Why doesn't a satellite connect automatically when it loses connectivity?
2. Why do I have to manually restart the router and then it works again for some time?
3. Do I have to install a timer on a satellite so that I can be sure that if the connection is lost, the system will restart at least 1x a day? Can such a function not be implanted in the firmware to provide a stable system?

We chose Orbi Pro because we want to have a stable system on sites.I'm grateful for any help/tip.
