RBK750 Smart Parental Controls Stopped Working (Paid Service)

That looks correct! You do the soft factory reset on the same page that you do the backup. When logged in you go to the Advanced Tab. Under Administration there is a link for Backup Settings. This is where you save a copy of current settings assuming you have made modifications and this is also where you Revert to Factory Default settings for the soft reset. I am attaching a picture of what the screen looks like. Good luck and let me know if it works for you! If it does I will likely switch my configuration around to make the 750 my primary router and the RBR50 as an access point. When I first bought the RBK753 there were no parental controls on it.
