we have noticed strange situation where we lost connection for 12 hours with router.
At first I've suspected that is power issue but energy operator did not confirm any issue in station location.
During the communication gap I've tried to reboot via sms management but without success.
After 12h router obtained mobile connection again with information in logs:
> 23:03:55 - Mobile data connected, IP: X.X.X.X Orange PL
> 23:03:46 - Digital OC output off
> 23:03:27 - LAN plugged in / Wired WAN connection non optional
Which looks like regular boot sequence (there was autoreboot on - but there was nothing in logs that autoreboot did anything) but according to our energy operator there was no gaps in power delivery.
The same situation is for mobile operator - there is nothing in logs about disconnections from network and operator claimed that they did nothing.
Last suspicious things are SMS that were delivered to router. There are messages from our national warning system (ALERT RCB) both in logs and in router storage but messages sent by me are not in logs.
There are saved in storage with proper timestamp (sending time) but there is nothing in logs.
Is it proper behavior? Does messages are stored with the sending timestamp not receiving?
Could router receive messages after connection gap and use sending timestamp in SMS Messages ?
Or router had connection with operatora, was able to receive messages but did not work properly?
(did not reboot via sms utility, did not allow to remote connection)
