I have a WRAP 2c board with 5.4 loaded and it keeps rebooting every night around midnight-4am, it seems to do it just once every night. In the log I just get router was rebooted without proper shutdown. I have turned off watchdog timer and it still does it. Is there a way to tell if it is a hardware failure or if its losing power somehow?

I know I have read about making a supout file as soon as it happens, but I am asleep every time it happens. Is making one 4 hours later too late?

Not too late, depending on the configuration an use.. What is logged in the board, etc.

Make the supout and send to support@

You can see the exact hour of reboot with the uptime. Look this and tell us if there is always the same time.

Just thought I would let you know I downgraded to 4.17 from 5.4 and I haven't had any reboots since (2 days now) so we will see if it holds. In mean time I will send supout file and see if they can find anything.

Well downgrading didn't help. I have sent another supout to support, I haven't heard anything back yet.
