Greetings!

I bought this product for advanced home network solution, because this type has those features I prefer. I've previosuly checked the feautres in tp-link simulator so could easily decide to buy this type for my home network as primary device. I use it without the OMADA features, as a standalone VPN router.
I've succesfully updated to the latest firmware by following update instructions in the download center related to it's hardware version and region. Until few weeks earlier I recognised that, the router randomly reboot itself. Tried to hard reset, then reconfigure it from zero by using different parameters, but after a while the random reboot still persist.
The question is why?
I've hard reseted many times, have not set reboot schedule and the random reboot is not repeat itself in a unique time period, it is full randomly occur. Soemtimes very often, sometimes after few days repeats. In the system log there are no related informations appear.

Thanks in advance for help!
