@sunzi,

This is not the intended behavior of the nodes. IF a node were to disconnect, it should automatically reconnect with the same settings, oftentimes not even requiring a reboot and should not require a reset.

What firmware version are you running? The M9 Plus has recently received a few firmware updates for stability and bugs, so please make sure you have checked for any available firmware updates.

I would also recommend making sure that the Decos are setup as a Mesh and that they were not accidentally configured as their own network for each node.

Is there a pattern to when the nodes disconnect? How are the nodes connected to each other? How is the main deco connected to your modem?

Does bringing the satellite node into the same room as the main node allow it to automatically reconnect and communicate with the network?
