Logs from wpa_supplicant ( sudo wpa_supplicant -i wlo1 -P wpa_md5.pid -c wpa_md5.conf ) wlo1: CTRL-EVENT-EAP-STARTED EAP authentication started wlo1: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0 wlo1: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=4 wlo1: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 4 (MD5) selected wlo1: CTRL-EVENT-EAP-SUCCESS EAP au
