Smart Lights Keep Disconnecting [Solved]

Updated on / dernière mise à jour : 12/09/2023



So you just bought new smart lights for your home or you may already have installed them since many months or years but, for some reason, they keep disconnecting and you are not able to open or close the lights anymore through your Google Nest or Amazon Echo.

To solve this problem, you may want to make sure that your smart lights are connected to your router's 2.4 GHz frequency. Moreover, if your router has a dual mode enabled (2.4 GHz and 5 GHz) then the frequencies must use different names. If both modes share the same name, then the lights may disconnect if they connect erroneously to the 5 GHz mode. This is notably the case with LIFX bulbs. On this page, LIFX states clearly that 5 GHz and Wi-Fi channels 12, 13 and 14 are not supported, that UDP and TCP port 56700 must be open, that only WPA/WPA2 or OPEN are supported and that the 2.4 GHz channel should be set to 20 MHz bandwidth… so many things to think about when installing and using such smart lights.

The best thing to do is definitely  to read the bulbs' connectivity checklist prior to installing them (companies may have different settings for their own products). It is also important to read on how to access your router to properly modify the settings (and at the same time make sure your router is secured with the use of a complex username and password; most importantly, avoid keeping the router's default username [admin] and password [password] to log in later). PCMag proposes an excellent article published online in regard to accessing the Wi-Fi router's settings.

And remember, as Leonard Cohen said, "there is a crack in everything. That's how the light gets in"!
