Unreliable network connection on ODROID N2+

I bought the HA bundle on Ameridroid which was delivered to me in Feb 2023… I was running HA previously on my Synology NAS in a Docker container, and simply backed it up and moved it to the odroid when it arrived… Everything transferred flawlessly and I was able to stop the docker instance and just plugged in the odroid to the network.

Last night, the network connection on the odroid just became unreliable. I have Zigbee2MQTT running on a separate Raspberry Pi, and it was just suddenly connecting/disconnecting randomly multiple times, resulting in light switches turning on/off with no reason… I first thought it was the Raspberry Pi, but after re-installing everything on the Pi, and still seeing the same problem, I took a closer look at the HA install and realised that my Philips Hue integration was also unreliable…

To confirm it was the odroid, I took it off line, and booted up my docker instance of HA, and everything instantly came back reliably…

What I’ve done on the odroid so far…

  1. Restored my last HA backup to see if it was something in the setup that went bad…
  2. Updated HAOS to the latest version…

None of the above steps made any difference, and I’m thinking this is probably going to be a hardware problem rather than a software issue…

Any other suggestions on what I should do?
