I am having a strange problem with an R450G: from time to time all lights turn off, User Led (green one above the Blue for Power On) lights up, no messages on log but “router was rebooted without proper shutdown”. Most of the times it reboots normally just after unplugging/replugging power cord, but sometimes User Led turns on again before the first beep.
As I found the case something hotter than usual on top, I took it off and did some tests: with nothing connected but a notebook with WinBox, System Health showed 39 to 44oC. Blowing hot air temperature increased to 51oC and… it happened!
But, if instead of blowing hot hair I increase processing to 100%, temperature goes to 58oC and stabilizes.
So my questions are:
- does this test assure the “freezing” is caused by overheating? Or is there something else I am not taking into account?
- once I’ve readen in other forums devices working with 60 - 70oC, is there any hardcoded upper-temperature limit I can change?
Many thanks for your help!
