I want to be able to use the parental controls on my netgear router

What model Orbi system do you have? 

You can see the SPC tile in the Orbi app if the following conditions are met:

You are in a country where SPC is available https://kb.netgear.com/000063796/
Your NETGEAR single sign-on (SSO) account is registered to a country where SPC is available in your MyNETGEAR account profile settings
The NETGEAR SSO account that you use to log in to the Orbi app is the same account that your router is registered to
Your router isn’t in AP (access point) mode
If any of the preceding conditions aren’t met, the SPC tile doesn’t display and the Circle tile remains visible instead.

Make contact with NG support for additional help and information.

Good Luck.
