Why Garmin 840 does not work with WPA3 WiFi protocol?

I noticed that Garmin 840 does not work with WPA3 based WiFi adapter. Is it fixable or is this a hardware issue? I have an old device that still uses WPA2 protocol and I am able to connect, but the Garmin device does not even recognize WPA3 based access points, which works fine with all my other non-Garmin devices (except some cheap Chinese phone, which also does not work with WPA3).

    Do you mean WPA3 ? I have the same problem with my Edge 840. Wifi sync says failed, though it does sync....most of the time. I think it's definitely a problem Garmin can fix. Seems ridiculous that in this day and age wifi connectivity is still an issue.

    Yes, correct. Thank you. But in my case it is different. Garmin 840 does not recognize those modern networks at all, does not show them in the list.

    Something I tried. Try creating a wifi hotspot on your phone or laptop/pc and see if your Edge will connect?

    Sure, I tried this too. The Edge does not detect my iPhone 13 access point.

    Garmin fitness devices featuring Wi-Fi do not support WPA3. You can find device compatibility requirements here:Setting Up Wi-Fi on a Fitness Device

    If the manual "Wi-Fi Sync" option is selected some time after the Edge 840 has synced (there are no new files to be synced), a "sync failed" message will be displayed.
    We are currently investigating changes to make this experience more user-friendly.

    That bogus "sync failed" message would be nice to get rid of. As a new 840 Edge owner, it confused me because when I sync using the computer Garmin Connect app interface and there is nothing left that needs syncing, it does not say "sync failed" it just completes the sync and of course nothing new is added. But at least there is no "failed" notification which leads users (me, for instance) to disconnect from WiFi and reconnect etc. because it leads one to believe that the WiFi connection was lost (why else would a "failed" message appear). So yes, this would be an improvement.

    You may need to change your router or adaptor settings. 

    Most will have a setting that allows you to choose whether to allow WPA3 device only or legacy connection.  You can also usually specify whether to allow mixed mode (allowing WPA2 and WPA3 clients to talk to each other) or WPA3-PSK (or WPA-Personal) which allows both clients to talk to the router (but not directly to each other). 

    I would usually recommend WPA3-Personal as most households will have multiple devices that only support WPA2.  This still allows WPA3 devices to talk to the router more securely. Mixed mode is generally not recommended as it lowers security for everything. 

    Garmin is a bit behind the curve here and it looks like their devices are not 'WiFi certified' and thus they haven't complied with the WiFi Alliance requirement that all devices certified since 2020 should support WPA3.
