Replying to IP Ban? +k for help

So my school banned me from the university's wireless internet about 4 months ago.  No warning or notification or anything--just one day I couldn't get on.  I've tried a bunch of different things no luck. 

Now today they just banned me from accessing a ton of websites using the ethernet port in my room (since I can't get on wireless).  I can't use google, can't check my email, can't use youtube, etc.  Thank god I can still get on NS though.  I've tried using proxy avoidance, that didn't work.  I think they have my IP address banned.  Is there any way to get around this?

I think its from downloading torrents (which I don't even do that much) but since they never notified me of anything I have no way to know for sure.
