After doing the latest update, it has been difficult to log into WiFi. I get a prompt to input the password and when I do WiFi fails to connect. It only connects when I press the power button for 9 seconds. Sometimes the WiFi band remains at 2.4 GHz and sometimes 5.8 GHz. Before the update the Spark always used the 5.8 WiFi bandwidth. I use an Ipad mini 2 and do not have an RC. I do not like the idea of pressing the power button to log into WiFi every time I need to fly. Any ideas?
