Our home router is located in my room, but my mom wants to control my siblings' access to the Internet because they won't sleep even if it's getting late. I can't just unplug the line because when I'm not there, they'll just go into my room and plug the cable back in. My question is: where can I configure the settings to control their access to the Internet? I don't need a time limit or anything. I just need to be able to turn the settings on to stop them from accessing the Internet.
