I had been extremely frustrated for over a week trying to get my A19 bulbs to complete setup. after about 15 attempts somehow i was able to get one light to complete, but the other two would not. i tried everything the troubleshooting site suggested including using the latest beta app. no luck
With ZERO support in sight from LIFX after sending 2 support tickets for my $59 each lights and no response, i tried to narrow down the issue myself. i took my bulbs to a neighbors house to test setup there on his phone. immediately completed setup. i reset the bulb, retried on my phone. and boom, it completed setup on his wifi. i determined it must be my router.
That helped me narrow my google search for help on the issue. and I found there are some older 2016 posts about this issue in this forum which resolved my issue immediately.
I am reposting this now ASKING LIFX DEVELOPERS AND SUPPORT to update their website’s troubleshooting section to list this simple fix so other customers can fix this quickly and hopefully avoid the weeks long frustration and potential product returns which i was just about to do. How i stuck it out this long i dont know but glad its working now.
The FIX - login to your Asus router (im guessing any model should work). Go to the advanced wireless settings > Professional tab > scroll down to “airtime fairness”. > Disable, and apply. I reset the light and immediately the bulbs completed their setup process and are working.
