From my experience, with two different 650’s in the last month and a half, and quoting a Traeger tech it should take 6-24 hours to update. And at some point in the process the update can burn out the controller. With Traeger on the phone and telling me what to do step by step we have determined that the controller in my second grill has done the same thing that the first one did. That is the update caused the controller to burn out. So I now have two grills that are DOA. From my research this is a known problem, so you have to ask yourself why keep shipping grills with known issues. Solve the problem. If I knew what I know now with the Wi-Fi problem and the controller problem I would have never invested my money in a Traeger. If you are thinking of buying, do your do diligence before you buy.
