I am trying to setup a time restriction on my router. I have tried shading the desired times in green and saving them; this doesn't work. I then reversed this and tried again only to find this doesn't work either! Basically I am a carer and I need to ensure the internet totally switches off at 21:00 and then back on at 08:00. They have a tablet which I can remove at bedtime but they have a games console and Smart TV which cannot be removed each night.

I have tried most of the settings but simply must be missing something

Any advice would be welcomed
