And the college hacking continues!
I've decided I'll probably set up a VPN/seedbox for torrenting, and use TOR for anything questionable, but before all that I want to speed up my internet. The wifi here isn't terribly slow, but if a lot of people are on it can lag a good amount, and if I'm already running TOR it's a pain in the ass. Luckily there are ethernet ports in all the dorm rooms, which are pretty fast. I could just plug into ethernet but that's too easy.
I grabbed an old router from home, plugged it into the ethernet port, and logged onto my laptop via my new wifi network. Everything ran really fast (as should be expected) for about 3 minutes until a notice popped up saying "you have accessed the internet from an unauthorized router. please disconnect immediately and your internet account will be re-instated."
Question 1) HOW DID THEY KNOW?!?!?!

Question 2) What can I do to set up my own wifi from the substantially faster campus ethernet?
