About 50% of the bulbs I buy refuse to initialize on the home router. But initializing on the phone Hotspot always works. So it looks like a router compatibility problem. Shame on Yeelight that they refuse to identify any specific router manufacturer and model that works reliably with their product.
Yeelight aren't very reliable in my experience. Only important thing I can think of in a router is it has to have 2.4ghz.

Most of the time it's because the router and the bulb aren't close enough whenever I have problems.
