• You can open it on terminal with the command sudo leafpad /etc/wpa_supplicant/wpa_supplicant.conf

• Or you go to the folder /etc/wpa_supplicant/, right click on wpa_supplicant.conf and choose Open With. Change the tab from Installed Applications to Custom Command Line and write sudo leafpad:

  

• Then you will find the reference to the eduroam network and change it to : * network={ identity="ab1234" password="myUOBpassword" ca_cert="/etc/ssl/certs/Deutsche_Telekom_Root_CA_2.pem" eap=PEAP TTLS anonymous_identity="@" phase1="peaplabel=0" phase2="auth=MSCHAPV2" priority=999 disabled=0 ssid="eduroam" scan_ssid=0 mode=0 auth_alg=OPEN proto=WPA RSN pairwise=CCMP TKIP key_mgmt=WPA-EAP proactive_key_caching=1 }

• Change your identity and password and save the file.

• After, run sudo wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B

• Your connection should work!
