You should respect your dad.  My advice: grow up.  I'm going to assume you're being punished for something.  I, as a non family member, am not going to get in the way of your dad's parenting.  Its good that he is limiting your use of electronics, helps build character.
 
With that said, for real.  Grow up and talk to your dad about it.  Let him know how you feel without throwing a fit, sit down and have a grow up conversation about it.  If you are really into computer and plan on doing more than just blowing your load on a porn site or blowing someones head off on a video game then tell him that.  Tell him that you want to be able to use your computer to learn how to do things, hell maybe even talk him into getting you a Lynda.com subscription.  Any good parent wants to help their kids grow to succeed.

Network stability prolly could be done putting your network under load?
a simple program could do this is iperf, and have few of them running from different PC or laptop so on.
