Over the past month approximately the disconnects have become increasingly frequent

It's been a little over a week. The setup seemed to be stable for a number of days. Then, brief and intermittent loss of wireless connection again started to occur a few times per day. This morning, the satellite currently in operation (only one is connected currently) would not connect even after multiple reboots, hard resets. Since the last post of Nov 9, there have been no changes to the system and no new devices added.

As above, there is a good wireless signal in proximity to the RBR and the issue seems to be with the broadcast to the satellites. I eventually switched the operational satellite, disconnecting the one that was operational and turning on the one that had been switched off. After a firmware update on the second satellite, it started working.
