noob confused with wireless

[heb1039]

I was able to get wireless when i was back at school, no problem. However, my computer can tell me that, yes, indeed, I have a wireless network, but that, no, I cannot connect. My modem is a westell versa link 327W, if that helps at all.

Help!

What you trying to tell?

I guess I'm not sure. My computer is not letting me hook up to my wireless at my house, but I could hook up to it at school (I'm in college). I'm trying to figure out what my problem is.
