wireless web woes

Is anyone else having trouble with their wireless internet? Maybe most Princeton students are too diligent for YouTube, but videos load really slowly for me or not at all, at least when I'm in my dorm room.

I feel like OIT is trying to resolve this problem though: I keep getting notification of new wireless networks. I started the year on puwireless and then puwireless 2, but in a semester and a half it's progressed through puwireless 3 to Networks 4, 5, and 6. Not sure where 3-5 went, but I'm currently connected to three different wireless networks.
Does this make my internet connection faster, or just more confused?
