Reset netgear R7800

Hello all,

I've a Netgear R7800 with an 8GB USB stick, completely configured with ext root, AdGuardHome, Wireguard and several other personal settings.
Every few months it looses most of the settings and the USB stick is not available anymore. (I do not know if this is the cause)
I have to configure all the settings from scratch.
Ofcourse this happens when you do not want it.
Am I the only one with this problem and is there a solution or workaround to resolve it quickly?
A backup won't work because most of the configuration is on the USB stick.

Thank you very much

Tom

auto-save the system log file to USB drive, maybe you could find something.
