Using the logs tool I can see this 11:16:20 wpa_supplicant: dbus: fill_dict_with_properties dbus_interface=fi.w1.wpa_supplicant1.Interface dbus_property=Stations getter failed 11:16:16 gdm-x-session: dbus-update-activation-environment: setting WINDOWPATH=2 11:16:02 wpa_supplicant: dbus: fill_dict_with_properties dbus_interface=fi.w1.wpa_supplicant1.Interface dbus_property=Stations getter failed 11:16:02 wpa_supplicant: dbus: fill_dict_with_properties dbus_interface=fi.w1.wpa_supplicant1.Interface dbus_property=Stations getter failed 11:15:58 wpa_supplicant: wlp3s0: CTRL-EVENT-SUBNET-STATUS-UPDATE status=0 11:15:58 wpa_supplicant: wlp3s0: CTRL-EVENT-CONNECTED - Connection to 00:26:f2:29:d4:ac completed [id=0 id_str=] 11:15:58 wpa_supplicant: wlp3s0: Associated with 00:26:f2:29:d4:ac 11:15:58 wpa_supplicant: wlp3s0: Trying to associate with 00:26:f2:29:d4:ac (SSID='NETGEAR' freq=2447 MHz) 11:15:58 wpa_supplicant: wlp3s0: SME: Trying to authenticate with 00:26:f2:29:d4:ac (SSID='NETGEAR' freq=2447 MHz) 11:15:55 wpa_supplicant: dbus: fill_dict_with_properties dbus_interface=fi.w1.wpa_supplicant1.Interface dbus_property=Stations getter failed 11:15:55 wpa_supplicant: dbus: Failed to construct signal 11:15:55 wpa_supplicant: dbus: wpa_dbus_get_object_properties: failed to get object properties: (none) none 11:15:55 wpa_supplicant: dbus: fill_dict_with_properties dbus_interface=fi.w1.wpa_supplicant1.Interface dbus_property=Stations getter failed 11:15:55 NetworkManager: <info> [1531304155.3344] supplicant: wpa_supplicant running 11:15:53 systemd: Started WPA supplicant. 11:15:52 wpa_supplicant: Successfully initialized wpa_supplicant I am assuming that wifi is failing at boot but succeding after login.
