======Connectiong via wpa_supplicant======

If you are not using Network Manager, so edit your /etc/wpa_supplicant.conf and make sure you start wpa_supplicant when connected according to the used Linux distribution.

  network={
          ssid="kolejnet"
          key_mgmt=IEEE8021X
          eap=PEAP
          phase2="auth=MSCHAPV2"
          identity="p007"
          password="password_for_eduroam"
          ca_cert="/etc/ssl/cert/AddTrust_External_Root.pem"
  }

=====Something is wrong=====
Run wpa_supplicant in debug mode:

  wpa_supplicant -Dwired -ieth0 -c/etc/wpa_supplicant.conf -d
  
If login is successful, you should find the following:

  EAP: EAP entering state RECEIVED
  EAP: Received EAP-Success
  EAP: EAP entering state SUCCESS
  CTRL-EVENT-EAP-SUCCESS EAP authentication completed successfully
  EAPOL: SUPP_BE entering state RECEIVE
  EAPOL: SUPP_BE entering state SUCCESS
  EAPOL: SUPP_BE entering state IDLE

Be sure to get an address from a DHCP server:

  dhclient eth0
