@DustinRH,

Sorry to hear about the behavior, hopefully I can help provide some insight into what may be causing it.

How are your nodes wired together? Do they pass their traffic through a switch? What Model switch?

When passing through a switch, it is important that the switch supports specific features regarding mesh backhauls. It is also possible, depending on the features of the switch that a network loop is being created when the nodes try to switch to a wired backahul - which then blocks the port at the switch.

If the satellite nodes are wired to the network through a switch, try wiring the nodes directly to each other and seeing if the behavior follows. This will help determine where in the line the communication is breaking.

The Decos will recheck their backhauls in a few situations when a new "active" ethernet connection is found (can trigger with swapping ports) or when a node is rebooted. This is also when the Decos will automatically optimize their wireless connections. If possible, you should also consider checking your ethernet cables for a fault. A fault could introduce a behavior like this, so you may try wiring the nodes directly to each other with a new cable to see if the nodes disconnect.

  @DustinRH,

To troubleshoot, you are going to want to first verify that the switch is the culprit by connecting one of the satellite decos directly to a port on the main deco node. 

If the culprit is found to be the switch, I would then turn your attention toward the loopback detection and spanning tree features of your switch. When the backhaul method switches between wired and wireless, a short network loop is technically created(~5s). Any loopback detection features of your switch may be taking effect and blocking the port. 

Disabling the loopback detection features for the ports should help, especially in re-establishing their backhauls. This feature is dependent on the switch's features but is likely present.

When the backhaul method changes or needs to reconfigure itself due to a change in environment, IP address, wiring, or any number of factors - a short loop may be seen by the switch. If they are happening at the same time, you may try and find a setting that is causing the nodes to want to reconfigure or refresh their wired backhauls.
