Hi. I just purchased Yeelight white and it works great. It can connect to wifi and I can control it. But, because i have spotty internet connection, i sometimes have to restart my router. Upon restarting, the light bulb is offline with refresh button shown and i can't control it anymore.Pressed the refresh button a few times but it's still offline. I have to switch the light on and off so it can reconnect to my wifi . Is there any solution to this ?
