I have really tried hard and long to update my scale to FW 3.11 to fix the WiFi issue, but to no avail. I have tried adding a new network to my router (Asus Zen Wifi) that only broadcasts at 2.4GHz, even tried a network without a password. It didn't work, although all my other devices connected without problems. I have also tried using the hotspot on my iPhone 13 with 'Maximize compatibility' turned on, but it doesn't work either. I follow the procedures scattered around the Garmin support site to the letter, but my scale just doesn't enter update mode -- I do not see any progress bars. A lot of gear icons, wifi icons, blinking or not blinking, but there doesn't seem to be any updating. Sometimes I turn on the scale and it displays the waiting icon (hour glass) and gear icon, but most of the times, it just takes a measurement, but can't connect to WiFi, as it is still on FW 3.00.
Does anyone have step-by-step instructions that have proved to be succesful? I am a former software developer -- long time ago -- so it is not that I don't know what I'm supposed to do. It just doesn't work.
