====== wpa-supplicant and WPA Enterprise ======
<p>This has been a challenge to get working, but I finally found the way. Hopefully this will make sense and work for most Linux distros (I set it up on Eeebuntu).</p>
  - Verify wireless drivers are working and the interface is up -- this should show an interface such as wlan0 and some configuration information
<file>
sudo iwconfig
sudo ifconfig wlan0 up
</file>
  - Make sure wpa-supplicant and wpa-gui are installed
<file>
sudo apt-get update
sudo apt-get install wpasupplicant wpagui
</file>
  - Remove !NetworkManager
<file>
sudo apt-get remove network-manager
</file>
  - Create/edit your /etc/wpa_supplicant.conf file (Sample):
<file>
ctrl_interface''/var/run/wpa_supplicant

network''{
	ssid''"your_ssid"
	scan_ssid''1
	proto''WPA
	key_mgmt''WPA-EAP
	pairwise''TKIP
	eap''PEAP
	phase2''"auth''MSCHAPV2"
}
</file>
  - Edit /etc/network/interfaces:
<file>
sudo nano /etc/network/interfaces
</file>
<file>
sudo nano /etc/network/interfaces
</file>
  - Run wpa-supplicant and wpa-gui
<file>
sudo wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
sudo wpa_gui
</file>
The GUI should open and prompt you for an Identity (username) and then a password. It should automatically get an IP address and you should be authenticated. You may need to run the following command to get an IP address.
<file>
sudo dhclient wlan0
</file>
===== Making it run on login =====
  - Go back to the terminal window and type:
<file>
sudo nano /etc/network/interfaces
</file>
  - Add the following lines in the part regarding your wireless card, as in the example below:
<file>
pre-up wpa_supplicant -Bw -Dwext -iwlan0 -c/etc/wpa_supplicant.conf
post-down killall -q wpa_supplicant
</file>
  - Go to**System->Preferences->Sessions**
  - Click the**Add** button and add this command
<file>
gksudo wpa_gui
</file>
It will prompt for your Linux login password again to run wpagui as root. Then wpagui will prompt for an identity and password for the wireless network.
