Windows 7 Can't connect to my school's wireless network

[JSO]

My laptop can connect to my wireless network at home but when I bring it to school it can't connect. My computer recognizes multiple available networks but wont connect to any of them. I have the correct username and password and the signal strength is excellent. In the connection status I am sending packets but I'm not receiving any. I've tried turning off my firewall and anything else that may be affecting it but nothing seems to work. I was able to connect last semester but I'm not sure if this was before I upgraded to windows 7.

My OS is 64-bit Win 7 premium and I have a Dell wireless 1515 Wireless-N adapter.

I had forgotten I had setup a static IP address at home and needed to change my IPv4 settings to obtain one automatically. As soon as I did that everything worked fine.
