Mine was up for months, then suddenly the on premise security camera wigged out, and users started calling about wifi. I logged in remotely, there was nothing of interest in the logs. I turned off wifi and on again in the GUI and all was good again. Running the latest firmware that supports DFS sort of.
The unit connects via Ethernet to a fiber gateway, which was obviously up. Everything is at default settings other than the WiFi configuration. Very basic.
The unit is in a crawl type space, not hot not cold not wet, sitting on a plastic box with nothing around it.
I have contacted support.
