How can I make my xbox 360 lag from a computer on purpose?

My brother is being a you know what and won't give me the game back. I want to make him lag a sh!t ton so he will get off and not know it is me, because I'll get in trouble if I just take it from him.

The desktop is hooked up to the same router as the wireless xbox is. How can I simply make the router lag and his connection go red?How can I make my xbox 360 lag from a computer on purpose?
Well, you could reset the router from your browser. It'd cause the internet to drop for a few minutes.
Open the Network and Sharing Center on your computer,
from there go to Adapter Settings, and then right click on the adapter
your computer is using to connect to the internet. Choose, "Status."
From there, click "Details" and look at the number listed as the "Default Gateway."
Type this number into your browser, as if it were a url.
It should look something like this: 192.168.2.1 or whatever.
From there you'll have access to your router (unless there is a password.)
Every router is different, so I can't help you beyond this point.

I used to live with an annoying little sister who often wouldn't get offline to do her hw.
Either I told her she couldn't be online and she threw a fit, or I'd block her mac address via the router settings and the problem would mysteriously be solved.

btw, I think this is more reliable than trying to use up your bandwidth. If you're going to do that, the easiest way would be to download a really popular and current movie with lots of seeders. It wouldn't take long to download though, but it'd probably download at max speed. No guarantees it's mess anything up for him though.How can I make my xbox 360 lag from a computer on purpose?
