read ac68u log to find out why router restarted?

[apollo18]

hello i have a ac68u and i just noticed that the uptime is 12 hours meaning it restarted 12 hours ago but i havent touched it for the past 3 days, what do i look for in the system log to find out the reason it restarted or what happened/? or will the log not show this

thx

 

[K-2SO]

Look where the log records change to an older date. This is when the router restarted. Check what happened just before.

[apollo18]

i dont really notice anything, seems to be random right? kinda like it randomly lost power?

 

[K-2SO]

I see it restarted at 3AM, but no obvious reason in logs. Monitor it in next few days.

 

[ColinTaylor]

Are you still using that 12v power supply instead of the correct 19v one?

i dont really notice anything, seems to be random right? kinda like it randomly lost power?

Something happening at exactly 03:00 doesn't sound random to me. It sounds more like a scheduled event.

 

[K-2SO]

Are you still using that 12v power supply instead of the correct 19v one?

Haha, this is what I was about to ask. Was looking for the thread.

 

[apollo18]

no no! this is my main router original power adaptor and everything the other is the access point

 

[L&LD]

What firmware version? What options/features and/or scripts is it running? Are the NVRAM and JFFS partitions full?

 

[apollo18]

found the issue! it was a slightly power outage i just noticed a bunch of my other electornics are missing time and are reset!!
thx for the help
