Why Your Smart Lights Keep Disconnecting (And How to Fix It)

"Alexa, turn on the living room lights." ... "Sorry, the living room is not responding." If this happens to you, you aren't alone. It is the single most frustrating experience in the smart home world.

Installer's Take: 99% of the time, your smart bulb isn't broken. The problem is that you are using the free router that your Internet Service Provider gave you. Those routers are designed to handle 10-15 devices. Once you add 30 smart bulbs to your house, the router panics and starts kicking devices off the network to save memory.

The Solution: Upgrade Your Network

If you want a smart home that actually works, you have to invest in the foundation: your Wi-Fi network. You need a "Mesh" router system. Mesh systems use multiple access points spread around your house to blanket the area in strong Wi-Fi, and they are designed to handle 100+ simultaneous smart device connections without breaking a sweat.

Alternative Fix: Switch Protocols

If you don't want to buy a new router, stop buying Wi-Fi smart bulbs. Instead, buy bulbs that use Zigbee or Thread. These protocols create their own invisible "mesh" networks separate from your Wi-Fi. Philips Hue is the king of this, which is why they are so reliable.
