myQ Setup and Programming - Chamberlain, LiftMaster, Craftsman, Raynor Garage Door Openers 

This video takes you through the process of setting up your myQ garage door opener from 2011-current to work with your phone, both for the current Wi-Fi Openers and for the older openers that don't have WiFi.
NOTE: Chamberlain will tell you that the internet gateway will not work with openers manufactured from 2011-2021, however it IS COMPATIBLE with those openers. It's just one of their several schemes to get you to buy a new opener.
Sorry the video was a bit choppy in the middle, I don't know why it is.
