My ASUS router has a devices list per mesh node. I can drill into each device (connected or offline) and select Bind to anchor that device to a particular mesh node. I had to do this because somehow by default all devices love to connect to my wired node (the one all the way at one side of the house, behind a brick fireplace).
The router doesn’t power-cycle anything, but it’s able to somehow refresh the connection with offline devices.
When I noticed my OG and plug went offline, I found them under the offline list, then unbind/bind it back to the mesh node. I also was able to just click on optimize and it would refresh the connection and come back online.
I tried running optimize before and didn’t notice any difference in signal strength. I suppose it might have done something but I couldn’t tell what…
