Has anyone had Netgear Orbi RBK753S-100NAS (firmware v4.6.3.16_2.0.51) rebooted by itself?

Hello.

It just happened about 20 minutes ago while I was away from my computers that were connected with network cables directly to the router. I wished its logs were longer to see what happened! Although, my 12 years old Debian Jessie v8 PC's dmesg -T showed disconnections and reconnections:

I had firmware v4.6.3.16_2.0.51 for over a month (last checked in the router a few nights ago) or so too so it can't be a background firmware upgrade.

Thank you for reading and hopefully answering. :)
