I met the problem when connecting smart led bulb bought on Post Australia. I am using iphone, when in Yeelight app, I have tried all the led bulb(color) the only works one is led bulb 2 (color) , As I don’t have a router at home, I open a hotspot using my laptop
Although I have tried reset the bulb many times, the connection process will stuck at 25% and fail. I also have tried Mi home app and it shows Device connected, Message sent to device but finally fail at Connecting device to network. And the problem is timed out.
