We could suspect the cameras... but what of?

I don't think so. This never happened with the laptop. Also IIRC (not 100% sure, but 99.9...) the lamps on the plugs on the switch where the cameras are connected were blinking fast as usual.

Apart of the hardware the other difference is that the laptop runs OS 15.3 and the mini-pc 15.5.

- Could there be a setting somewhere to shut down eth0 from time to time?
- Could such a thing exist in the hardware? BIOS?

It is strange that it always happens Saturday nights, but maybe its coincidence.

Hi Daniel,

I have no idea if this is related, but I've got a couple of Reolink PoE cameras now,
and they automatically reboot themselves every every Sunday morning by default.
I think they do this to make sure that any malware collected during the week is
completely removed. It probably improves overall reliability too. The timing of the
reboot can be changed, and it can be turned off. Does your system have
such a feature? Could it be related somehow to your problem?

Regards,
Lew
