So I'm trying to connect to my school's wireless network and it's a no-go. I can see the network on my list and the signal strength is great, but when I attempt to connect to it, it fails. Xubuntu's way of showing the process is an icon that has two lights with a light that swirls through both of them. The first one that lights up is my wireless nic I imagine with the second being their router or whatever. The second one doesn't light up

So how do I find out what's wrong?
My wireless NIC works perfectly fine with other networks, btw.
