Yeelight Bedside Lamp - TP Link Deco2

Hi guys,

Device: Yeelight Bedside Lamp
Modem: TP Link Deco M4

When i setup the light the first time i can get it connected and working, but after a few minutes it goes “offline” - The device is no longer discoverable in the application.

If i reset the lamp and follow the instructions i can get it working again, but after a few minutes its back to where it is.

Is there anything that i can do to fix this?
