We have a RUT240 4G Router that seems to be continuously rebooting. Plugged in to mains power, lights come on, but then enter a loop of LAN/WAN switching off, then signal strength lights switch off, then all back on and repeat. I can't see any WIFI network being offered and it gets very hot.
We did plug in 48v PoE by accident, but I feel like if that was the culprit then the device wouldn't power on at all via mains power? Can anyone confirm this?
