My friend needs to connect to the wifi in our school, which uses a Protected EAP (PEAP) Authentification.

He installed the Gnome GUI by the way.

When he tries to connect to the wifi however, after putting the login and password, a window pops up warning that he didn't select a CA certificate (which is not needed), and he can't interact with that window. Meaning that he can't select ignore and then connect.

Is there a way to connect to this network by using the terminal?

Edit: My question was identified as similar to another, but the answers there doesn't help us. The network we are trying to connect to is one that needs username and password [Protected EAP (PEAP)]. The question/answers from the other thread only talk about the usual wifi where we only need to input the wifi's password.


In the words of kemtnbkr on the Ubuntu forums:

Make sure wpasupplicant is installed

  1. Remove network manager from startup apps; log out and log back in

  2. change your /etc/network/interfaces to: Code:

    auto lo
    iface lo inet loopback
    auto wlan0
    iface wlan0 inet dhcp
    wireless-mode Managed
    wpa-ssid **censored**
    wpa-ap-scan 1
    wpa-proto RSN WPA
    wpa-pairwise CCMP TKIP
    wpa-group CCMP TKIP
    wpa-key-mgmt WPA-EAP
    wpa-eap PEAP
    wpa-identity **censored**
    wpa-password **censored**
    wpa-phase1 fast_provisioning=1
    wpa-pac-file /home/kyle/Downloads/chain2.cer
  3. With terminal: Code:

    sudo ifconfig wlan0 down
    sudo ifconfig wlan0 up
    sudo dhclient wlan0 -v
  4. You are Connected.
