If you are running into setup issues with your LIFX bulb, there are a number of things you can try to resolve these issues.
These are not required steps, simply troubleshooting steps if you are having issues with setup of your LIFX bulbs. We anticipate the steps in the app are sufficient for the vast majority of users to get their bulbs setup.
Power Cycle all parts of the system
This may be a simple step, but it is one that can often fix a number of issues, sometimes without explanation.
- Phone or Tablet device: To power cycle your phone, simply hold down the power button, and tap the power off button, slide to power off, or whatever the phone requires. Then, power back on, by pushing the power button, and waiting for the device to boot up
- Router: To power cycle your router, often, there is no power button. Simply unplug mains power to the device, wait about 30 seconds, and then plug back in mains power. Please check your owner's manual for the device, to be sure there is not a different method for power cycling.
- LIFX Bulb: Simply powering off the lamp, or light switch the bulb is connected to, and powering back on is all that is required here. An additional step, which can be helpful when having issues, is to Hardware Reset the LIFX bulb.
Bulb direct Wi-Fi connection issues
Turn off cellular data on your iOS or Android device, during setup, to make sure the device is connecting successfully to the bulb Wi-Fi during setup.
The latest OS versions for many devices have warnings about network security, and seek internet access for each connection. LIFX bulbs do not have an internet connection until connected to your Home Wi-Fi, which can cause issues during setup, with these newer operating system versions.
Same network name (SSID) and password for 2.4Ghz and 5Ghz networks
If your network shares a single SSID for your 5Ghz and 2.4Ghz network, and you are having issues with successfully connecting LIFX bulbs to your Wi-Fi network, you can try disabling or changing the SSID for the 5Ghz network during setup.
Depending on how the router works, it may not route the LIFX bulb to the correct band, causing failure in setup. By disabling the 5Ghz channel, or changing the SSID during setup, you allow the router to only send 2.4Ghz connection to the LIFX bulbs, which should address this issue. After setup, the network can be set back to the original shared SSID, and should work with this setup.
AP isolation (also sometimes called Client Isolation, or Guest Isolation mode) is a feature of many routers. This allows for you to provide internet to devices, without allowing them to access other devices on the network. For LIFX bulbs, this setting prevents completion of setup, and control of the bulbs on the local network. If you have this feature (or a similar, with function of preventing local networking) it will need to be turned off, in order for setup and local control to be accessed.
Many routers have Guest Networks, which do this by default. If that is the case for your router, you will not be able to use the Guest Network feature, for the connection of your LIFX bulbs. They will need to be on the main network, if you cannot disable this feature on the Guest Network for your router model.
Many routers provide auto-channel features. This means, when setup, or power cycled, it will scan the area and pick a network channel to operate on. If you are having issues with setup, changing this from Auto, to channel 1, 6, or 11 may actually improve network functionality, and allow for you to complete setup.
This is a feature strictly on BT Internet services in the UK. Smart setup can prevent correct setup of some devices, including Chromecast, and LIFX bulbs. You can follow the steps on this BT support article, to disable Smart Setup on your BT Homehub, as a step to troubleshoot, and likely address setup issues.
Firewalls and Port blocking
If you have a firewall, or port blocking enabled, in your router, or via your ISP (internet service provider), even if LIFX are able to connect to your local network, you may be prevented from setting them up with your Cloud account for external services. LIFX currently use port 56700 to connect to v2.broker.lifx.co for connectivity to your Cloud account. You will need to enable access to this port, if it would otherwise be blocked. This is not a common default setting for routers, but one that needs to be changed, if your configuration prevents access.
