I forgot to mention this in my first post. Do not bring a router to rez!
There are many places for wireless internet around campus, so there's no need for one. They're against the rules for a good reason. They screw up the internet connection within the residence and then you'll get in trouble. In my first year, a person on my floor used his own router, and caused the entire internet connection to shut down causing a wide spread panic!
It was fixed fast, but they were told to not use it anymore. Trust me, they're not needed.
And if you were thinking that perhaps the residence has a router already there for you to use, they don't. Internet is a wired connection into the wall, and some residences have wireless internet, but not many.
