My dormitory has a wifi. And it seems that Yeelight bulb cannot connect.
When I try to connect, I saw the message “Public Wifi cannot connect”. In my room, I can use the internet when I put my id and password in the browser, similar way of authentication of Starbucks wifi.
If my room can access the router like this, I cannot use the yeelight bulb color? I did not know this fact when I purchased the item.
