First of all this is my first HOWTO and it details how I got connected to Lehigh University's wireless network with wpa_supplicant. I decided to post this as I was having trouble finding info on this subject [of connecting to a University 802.1x network] and figured this might serve as a springboard to help others connect to their own 802.1x University networks.

**I recommend backing up all config files before editing them and take no responsibility for any damage this may cause**

Ok, that said let's get started, first make sure you have the wpa_supplicant installed.
Code:
sudo apt-get install wpasupplicant
Now create the wpa_supplicant configuration file
Code:
sudo gedit /etc/wpa_supplicant/wpa_supplicant.conf
then paste the following, edit as needed and save.
Code:
# for lehigh university
network={
        ssid="lu"
        scan_ssid=1
        key_mgmt=IEEE8021X
        eap=PEAP
        phase2="auth=MSCHAPV2"
        identity="your university login name"
        password="your password"
}
Now edit /etc/network/interfaces with
Code:
sudo gedit /etc/network/interfaces
adding
Code:
wpa-driver wext
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
under your wireless interface.

Restart networking
Code:
sudo /etc/init.d/networking restart
and enjoy!

Hope this helps somebody
