Orbi RBR40

I purchased my unit with two satellites around 5 years ago.  It is now beginning to have problems staying connected to my modem.  The only thing that works is to completely disconnect the wires and reconnect.  It retains is connections for a few days before losing it again.  What do I need to do to keep my connection.  Is my system end of life?

Yes, this product is officially "End of Life"

Nevertheless, this is not causing the router to lose connection to the modem.  Assuming "nothing has changed" recently, the problem may be difficult to diagnose.

What specific modem is the router connected to?

Does anything appear in the router log file when this happens?
