RBS350 is always pulsing white and not connecting to the router

[Starani]

I tried all syncing syncing options like reset, firmware update and pressign sync button for 2 minutes.

My RBS 350 is not syncing with RBS350 router and always pulsing white.

I am starting to give up. Network map is not showing the satellite at all.

Please help!!

many thanks

What Firmware version is currently loaded on the RBR and RBS?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

How many RBS are deployed? 
What is the size of your home? Sq Ft?
What is the distance between the router 📡 and satellite(s)🛰️? 30 feet or more is recommended in between RBR 📡 and RBS 🛰️ to begin with depending upon building materials when wired or wirelessly connected.

Ethernet connect the RBS to the back of the RBR get any IP address for the RBS?
