I have been having a problem with my network which is made up of 2 S7 units adn 2 M4R units.  Everything has been fine and stable for 6 months until the last two or three weeks when it keeps dropping the network.  The only thing that I can think of that has changed is that I updated the Firmware on the two M4R units to 1.5.8 20230619 Rel.48552

I currently have one of the S7 units as the Main unit.  Sometimes the main unit drops, but often it is the satellite units that drop out.

Is there a log of this behaviour?  I don't know if it is the internet providers problem or the Mesh.  SHould I take the system apart and redo the network?

Any help would be appreciated.
