I want to set the wifi to turn off at 11 pm and back on at 7 am. What is the best way of doing this?
Welcome to the community!
If you will have to use an app to do it if you are using an Android phone you can check a few of them out here and see which one works best for you.
For iPhone unfortunately I do not think there is any way to do it even from an app as far as I can see.
