Hi Jouni, My earlier logs were big in size. So not delivered. So I recaptured and attaching only required logs. AP-Problem.log I switched off the router around the time 1456401394.205710: dbus: flush_object_timeout_handler: Timeout - sending changed properties of object /fi/w1/wpa_supplicant1/Interfaces/1 Around the time 1456401598.821077: wlan0: Setting scan request: 1.000000 sec I gave the scan command. The dbus sequence I follow is, AddNetwork SelectNetwork Then I wait for "completed" signal from dbus udhcpc -iwlan0 to get IP once connected. When there is problem connecting ie at the time of reconnect, SelectNetwork with the object obtained as part of AddNetwork Then I wait for "completed" signal from dbus udhcpc -iwlan0 if connected. I could see from the log, 1456401549.760162: Fast associate: Old scan results After this there is continous scan requests ignored. How to handle this case? Regards, Johncy.
