Parental Controls, Genie, and

I discovered that my Parental Controls, which had previously been set and were working just fine, had somehow become disabled. So I fired up Netgear Genie on my Mac and hit the Parental Controls Tab. Genie has to "check the router firmware", which it tries for minutes on end before finally telling me "You don't appear to be connected to the Internet. Please connect to the Interrnet through you NETGEAR router and try again.", which is totally false—I'm connected right now! Would love to get ideas on:

1.) Why the PC's were disabled in the first place?

2.) Why the R8000 (running Firmware 1.0.3.46) tells me I'm not connected to the Internet both in Genie and when I log into 192.168.1.1?

3.) How to fix this and get my PC's re-established

And finally, I've owned Netgear routers for years and have been using Genie for years now. I've NEVER been able to just Quit the app on my Mac. Selecting Quit freezes the application—I always have to Force Quit it to get out of it (which is why I only use it as a last resort, preferring to log in through my browser).
