My university uses WPA2 Enterprise encryption for students to login their wireless. In NetworkManager I have keyed in everything that they needed

  • Security : WPA & WPA2 Enterprise
  • Authentication : Protected EAP (PEAP)
  • CA certificate is not needed
  • PEAP version : Automatic
  • Inner authentication : MSCHAPv2
  • Username and Password are correct.

Everytime I try to connect, I get a window asking me to input my password over and over again

There is a bug report here: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1104476

A workaround is to remove the line

system-ca-cert=true

from the configuration file found in /etc/NetworkManager/system-connections/

    still happening on 14.04 (current beta) – prusswan Apr 12 '14 at 7:29
  • Yep, still in 14.04. – Reece Jun 4 '14 at 20:25
  • still doesn't work without this line... – Sanjay Manohar Jul 29 '14 at 22:28
  • @SanjayManohar Try the answer below regarding the WPA supplicant issue, or just try a different wifi card if you have one--that worked for me, without modifying the config file. – Brian Z Aug 5 '14 at 16:13

Here's a work around.

  1. Open a terminal (Alt + F2) and run the following commands:

    cd /etc/NetworkManager/system-connections
sudo touch SSID #SSID is the name of the profile, e.g. eduroam
sudo nano SSID

  2. Then edit the "SSID" profile as following:

    [ipv6]
method=auto

[connection]
id=SSID #(e.g.EDUroam)
uuid=9e123fbc-0123-46e3-97b5-f3214e123456 #unique uuid will be created upon creation of this profile
type=802-11-wireless

[802-11-wireless-security]
key-mgmt=wpa-eap
auth-alg=open

[802-11-wireless]
ssid=SSID
mode=infrastructure
mac-address=0A:12:3C:DA:C1:A5
security=802-11-wireless-security

[802-1x]
eap=peap;
identity=studentid123123
phase2-auth=mschapv2
password=mypass123123

[ipv4]
method=auto

Modify the above file and it should work.

    It works! Thanks @keith! Here are the changes I had to do: (1) removed the line system-ca-cert=true and (2) replaced password-flags=1 with password=mypassword. – Marcelo Jul 24 '14 at 12:57

I had the same problem at work I followed the instructions and changed the system-ca-cert=false but I also had to go in and change the wireless driver settings once I made the changes it connected right up. check out the link where I got the info below

http://wireless.kernel.org/en/users/Documentation/wpa_supplicant

-o<driver> and -O<ctrl>

/usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service

[D-BUS Service]
Name=fi.epitest.hostap.WPASupplicant
Exec=/sbin/wpa_supplicant -u -f /var/log/wpa_supplicant.log
User=root

[D-BUS Service]
Name=fi.epitest.hostap.WPASupplicant
Exec=/sbin/wpa_supplicant -u -onl80211 -O/var/run/wpa_supplicant
User=root

  • Appending the second entry to my file worked for me, thanks! – Matthew Read Jun 16 '15 at 21:17
  • Adding -onl80211 solved for me, thanks! – Tamas Hegedus Mar 17 '16 at 11:22

You might also need to specify the Domain of your enterprise by adding it before the username like so: Domain Name\Username beside commenting/deleting the above mentioned line..

I assume that you're using self-signed certificate (you said: "CA certificate is not needed"). If so, make sure that the certificate is trusted by you when establishing the connection.

    No, by not needed I mean they do not require us to use any certificate while connecting. – Balraj McCoy Apr 10 '13 at 11:02
  • I don't understand what's the purpose of using PEAP without the certificate, but OK. Are you able to connect on any other OSes than Ubuntu? I'm having the same WiFi infrastructure in my company, so maybe I'll be able to help. – Guardian Apr 10 '13 at 11:20
  • I'm able to connect using Windows fine. There's a guide on Windows connection here : studentprojects.wordpress.com/tutorial/… which I followed on Windows and it worked fine. Tried replicating it in Ubuntu and it failed. – Balraj McCoy Apr 10 '13 at 12:14
  • @Guardian you've apparently never tried PEAP-MSCHAPv2. First you connect only with username and password, then it allows you to download certificate. I've seen in this in around 5 universities already. And I have no idea how to download certificate after I've connected to network. wicd allows to connect without certificate. – holms Jan 18 '17 at 6:55

  1. Try resetting your password (by contacting the sys admin or using an online form to send password reset link to your email address)
  2. via network manager gui, edit the wifi connection to update the password field with the new one and save.
  3. Reconnect to your wifi and it should be working now!
