Why did my TZ250W reboot on its own this morning?

Larry

I was reading the New York Times on my iPhone at breakfast this morning when I got the prompt that the app's settings weren't enabled for Verizon's service. That was strange because I was using Wi-Fi - only that was no longer appearing in Settings.

I looked at the firewall and saw the wrench was lit orange. And, right before, my eyes, I realized the device rebooting.

As far as I know, the log gets cleared out upon reboot. Is there any other location that I can access that might provide a clue as to what happened?

Running firmware 6.5.4.8-89n for quite some time.

Thanks!

Hi @Larry

Download the TSR and check the last reboot cause.

Let support team to analyze the TSR.

@Ajishlal if you are referring to the "Watchdog reboot information" then I am now more concerned than yesterday:

I can't believe this little puppy has been rebooting EVERY Sunday morning!

Case is now open. Calling on it soonest.

Hi @Larry

Yes watchdog will give you the information.

as well as check is there any scheduled reboot configured.

If setting a schedule requires use of CLI, you have to know I certainly didn't do it (GUI is my middle name...)
