How to put a time limit to how much kids can use the Internet?

My brother keeps playing minecraft for hours. When my mom takes the computer away he always finds a way. So my mom had asked me to find out if there's a way to just have my brother use the internet for just an amount of time?

Well if its a mac you can go into the settings app and into the parental controls pane and select th amount of time he can use the computer.

My dad has the internet in my house automatically set to turn on at 4:00 pm and turn off at 9:00 pm (though for some reason it was already on this morning)

HELL yah! If you are using a windows OS, google how to setup a "Task Scheduler Task to disconnect the internet" and I'm sure you find tutorials that will shut it down after certain amount of time. They do it in libraries all the time, too!

Yeah you can use Wi-Fi for this.put a password on Wi-Fi tell it to your brother and afters some time change it

Get into your Wi-Fi and restrict access

All these will work with Windows, but there are so many ways to play MC today that he won't have to use a Windows system to get to it.

But, if You want to set time limits on the amount of computer use You have a few ways to go about it…

Do a search for "internet cafe software", and "user acount time limit"… And Youi'll find several links that will help with the research…

There's also the option of using something like a time-based power cord adapter that would be used for things like house lights or lawn sprinklers that would come on automagically at set times of the day - they're very often used with Christmas lighting sets.
