I have my BE16000 nodes running in AP mode. They are all connected to a 2.5Gbps switch, on the same subnet, and "seem" to be functioning normally according to the Deco app. However, I have been noticing some high latency and intermittent connection drops in devices connected to the child nodes. After some digging I have discovered that despite being connected via ethernet, the child nodes appear to be relying on 6Ghz channel backhaul instead of wired. Upon initially being plugged in, the nodes will rely on ethernet, but it seems that after 30 seconds or so, once the 6Ghz connection to the main node is established, it relies on that for backhaul 90% or more of the time.

This is incredibly frustrating and causing issues with my network including increased latency for locally hosted applications used over the network and STP confilcts that are disconnecting nodes (and all connected devices) from my network when the child node switches between ethernet and wirless backhaul. This even happens between devices that are hardwired to the nodes directly (and thus should not be relying on wireless at all).

This mesh system was far too expensive for me to be experiencing these types of issues. For some of my use cases it is borderline unusable as the system's inexplicable fallback to wireless backhaul causes unacceptable latency. 

As far as I can tell there is nothing I can do to turn off wireless backhaul manually, so I'm just at the whims of however the devices decide to route my traffic. What can I do to fix this problem short of throwing the BE16000s in the garbage and going with a different brand of mesh system?
