Setup Troubleshooting
- Try powering off other LIFX lights and set up one light first.

- Check your router for AP isolation (Client isolation) and make sure it is off and no VPN, Firewall, or Port blocking protocols are enabled.
If you have completed the setup of your LIFX light, but the light occasionally becomes uncontrollable / disconnected in the LIFX app, you are experiencing connectivity issues.
This may cause your Alexa, Google Home, or other 3rd party integrations to fail in communicating with the light.
If you have several LIFX lights, but only one is having this issue:
Check that the light is not used in a socket with a dimmer switch
Try switching this light with another of your working LIFX light, and see if the issue follows the bulb
If you are still experiencing connectivity issues, please submit a support ticket.
If you've recently changed your router or network name, see our guide on setting up a New Wi-Fi Network.
