Hi, strange question but is it possible to disable my home internet connection for a few hours each day?
just take cable out of phone socket or turn router off - not rocommended on a regular basis as it will have bad effect on your broadband - stable conenction 24/7 is best
Rather than turning off, to preserve your profile I think you have the ability via Windows Defender to stop internet traffic totally.
If you are just wanting to stop a device from accessing the Internet at certain times you can use the Homehub's built in access control.
See link how to do that.
It is easily over ridden so may not be suitable if for instance it is to stop a tech savy child from accessing the Internet when they should be in bed.
