Google Nest Community

I got Google Wifi in the house and until recently the pause fumction had worked just fine, but now when I pause items they are still online, my kids has a laptop, iPad and a desktop which I have set schedule for, not working, our Samsung tv still run...

I'm trying to setup my outdoor Meross plug and it ask me in the setup procedure to add to 2.4hz, but I have no idea how to choose between the two, it's easy on my router, there is typically two different logins, how do I set that up for Google wifi?
