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

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

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.

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