First & foremost, what you're doing isn't working. You can insist you have ultimate authority in your house ("my house my rules"), but it's pointless because it's not working for your family. You aren't getting compliance, only tension.
What I would do is...
Tell him he can have the WiFi & mobile phone etc back when he sits down and you have worked out together what are reasonable expectations. If you don't negotiate at this age then they A) sneak behind your back to do WTF they like B) openly defy you C) don't develop skills to make good decisions. You have an opportunity here to help guide him into being a person who can make better decisions. Take it.
When you sit down, briefly Tell him why you feel those rules need to apply, and if he doesn't want those rules, ask him to give you reasons why those rules shouldn't apply,. Get him to use reason to justify his position. "Because I want to" isn't good enough, but he can say "I know I will get to bed by 10pm anyway so you don't need to take the phone off me" etc. Nudge him to reasons.
What you're trying to do is nudge him into better decision skills, based on his values.
A good strategy is to Find the common ground does he agree it's your job to protect his health and that includes his sleep (and he should not disturb your sleep with noisy games at 1am) - then how can he help you do that? Does he agree that it's nicer for everyone if he doesn't smell then how can he help make sure that he doesn't reek. Does he agree it's your responsibility to make sure he does schoolwork -- how should he help you fulfill your responsibility. etc. Help him find reasons why he wants achieve some same things as you. Then try to be very open-minded if he has any suggestions how to achieve what you have jointly agreed is a good thing to achieve.
I'm probably not explaining well. He may be so hostile that you might have to try a few times to get him to try to find common ground. But I think you can see that you just dictating to him is not working. It becomes an increasingly poor strategy as they get bigger. Give him some part of the decision making.
If he's very furious, then don't try to approach him about the rules, but look for peace-making moments. So if he's willing to talk about anything (short of him being abusive)-- you listen. Try not to tell him your opinions. Listen, and if he's not hostile to this, sometimes ask him more about his opinions. Even if it's just which type of bagels to buy or what to watch on telly. You want to become someone he likes to talk to about the random stuff in his head.
they also respond well if you say "Well I think that's a bad idea because... but I'll let you make that bad decision if you want." then they engage and work thru better decision skills what they really want, and what the real benefits or risks are in any plan of action. It can feel a little like an argument but you get thru it if you're willing to let them face consequences, and in meantime you fulfill your job to help them learn how to work thru decisions. You can't just decide what's best for him like when he was little.
