The CRS125 is restarting by itself and losing configuration. I don't know exactly when it loses the configuration, when I see the ip went back to 192.168.88.1. I've updated the firmware of routerboard, but it didn't help. It started after upgrading from a very old version to current versions. Before it worked normally.
What I have to do to resolve it?

try directly netinstall, if not solve, the nand is out....
