thanks for your answer. Yes, i definitely had network, and FOTA is enabled. It worked fine in the past, keeping the config after updating.
Now i updated using a file upload, and i lost all configuration!!! :-(((((((( I can't restore backup (since the FW version changed), and if i load a restore point i'll go back to the previous version again....
This last thing is what i did now, and worked perfectly, but i don't want to reconfigure everything just for a (minor) FW update... in that case i'd go for version 7.x.x, having product code RUT950V02XXX version 7 should be supported right?
Thanks and greetings,
