Sorry for re-post, my prior one from end of August seems to have been removed?

UPDATE 10/6/2022: It took some time (which is why I didn't respond to an admin's reply), but today I noticed yet again the deco unit ethernet connection slowed down from 330 to 9. I had to unplug it and leave it to cool off for a bit in order to get back to 330. If this is a heat issue, the weather is back to warmer today so perhaps that's what's going on.

ORIGINAL FORUM POST THAT APPEARS REMOVED

I have multiple installations of Deco M9 plus using Ethernet backbone/backhaul. All of the installations after about 7-10 days have individual nodes disconnect from the Ethernet and switch to using the wireless backbone/backhaul. A reboot of the node does not re-enable the Ethernet backhaul connection, you have to physically unplug the node from electricity in order for the Ethernet backhaul to re-enable (and even this takes multiple unplugs).
