Internet Issues

[Dbrine757]

So to sum up why I'm in this situation, my mom and dad got into an argument last night and my dad controls the internet whenever he's mad. Before he left he did something to the internet on everyone in the houses computer we are wired. It shows it is "Connected" and shows connected everywhere. Yet whenever you try to connect to any website or do anything that requires internet it won't connect. My mom has tasked me with fixing this because she things I'm knowledgeable with this type of thing. We cant get to the router or switch because my dad has locked it up in the boiler room. We don't know when he is gonna come back because when they right he disappears for weeks on end sometimes. I need to find out how to bypass whatever he has set to block the connections of our computers, I don't know how to tell what he is blocking about the computer.
