My daughter moved in on Tuesday (athletes move in early), and we got her Wifi connection set up and working with no problem; both computer and phone. Seems to work great. Make sure to follow the instructions here - http://computing.vassar.edu/network/encrypted.html - Note that when you download what they tell you to download (at least for Windows 8), it doesn’t all work exactly as the directions say…but it will all work and be fine.
If you find that you need an ethernet cable in your room, then do that, but assuming you want to take your computer with you, you’ll want the Wifi to be working also.
