Jiaoyue cannot connect to Wireless

Yeelight Jiaoyue YLXD05YL 480
TP-Link Archer C50 AC1200 (V3) Router

  1. Which lamp should I chose in Yeelight Android app? (There is no Jiaoyue to pick)

  2. I cannot connect my lamp to my wireless router. I once was able to and then someone hit the light switch and since then I cannot reconnect my lamp to the wireless network. I reset the lamp several times and the app finds a lamp but it cannot connect to wireless. It stops at 99%. Lamp and router are in the same room. I am in Germany and the yeelight server i use is also in Germany.

Please help me.

Could you have a try with changing your router’s DNS server to instead of using automatically allocation?
