Yeelight Color Light Bulb YLDP06YL - Connection timeout after upgrade

Hi all,

I upgrade my color Yeelight Light Bulb with the firmware 2.0.6_0065
I have the same problem with firmware 2.0.6_0051.

My leds can’t connect t my wifi network, they don’t have IP from DHCP.
Everything was working correctly with firmware 1.4.2_0035.
I also used LAN Control.

Is there a way to downgrade the firmware ?
How can I reetablish the conection.
I did a reset of the LED 3 times that was working but it doesn’t solve the connection timeout.
Is it better with YLDP13YL ?

Regards
Luc

Could you find another router or just use your phone as hotspot to test?
