Updating over Wi-Fi can sometimes be problematic when there are quick drops in internet connection. You may think the internet connection is solid, because you can use internet applications and other devices do not have issues. You can still have minor drops in connection that are not noticeable when performing other activities such as streaming.
Our software download process requires a consistent internet connection throughout the entire download process, one small drop and it will cause the update to fail and prompt you to retry. Sometimes you can try multiple times and eventually have it completely download the update but sometimes you will need to update the software using another method. Please see the alternative methods listed below.
