Not sure if it was the Update or coincidence, but after being on this update for an hour or two, I started getting disconnects and noticed that the POE/WAN port would show disconnected for a few seconds and then come back up. First I turned off Anti Bufferbloat since that's what I was tweaking at the time and it seemed like it got better. Then the issue started to come back. Now I can't get it to stay up for more than a few seconds.
I've tried reverting back to the First DumaOS (dumaos-2.1.2.10) and then went back to R1-v-1-03-6j. Reverted back to Factory Settings. Every once and a while I'll see it come up and then go back down. I've also tried different cables, and plugged the WAN port into different ports on a Switch. Still no luck.
