- About a week ago the watch suddenly lost the ability to scan for nearby wireless signals after working fine since the time I purchased it in May 2020. It also apparently thought the two previously saved networks (home network and phone hotspot are both 2.4Ghz) that both worked the day before were not valid, and didn't seem to even try to connect to them anymore. The message from the watch after 1-2 seconds is always "No Wi-Fi Networks Found", when both networks are still present in My Networks on the watch.
- Doing a soft reset later that night didn't improve the situation.
- I then tried creating a new 2.4Ghz guest network (with no security protocol or password) using our router's web interface and while I could see and connect to it from my Pixelbook, the watch still couldn't see it, or any other networks. Nor could it connect to this guest network when added manually.
- After dusting off our old vivoactive 3 music, I found it was still working with the same home WiFi network referenced above.
- I later purchased a new Forerunner 245 music from Amazon and received it Friday. This watch also can see and connect to our home WiFi network. My podcast app, Runcasts, is able to get new content without issues with both this watch and the vivoactive 3 using WiFi.
- Another interesting comparison is the behavior of the problematic 6X Pro vs. the FR245 when attempting to add a WiFi connection via the Garmin Connect mobile app and Garmin Express (I tested with both). In the case of the 6X Pro, no networks were returned from the device to the app, only a manual add of a connection was possible. Even then, the same error message mentioned above was returned when trying to connect. The FR245 did return the expected list of connections, and worked perfectly.
- Downloaded Garmin WebUpdater, connected 6X Pro, and chose to reinstall the same version of software. Afterwards, the same error message was presented when trying to connect to WiFi. Later, I tried the "add a network" option and the watch still couldn't see any networks.
- Today I finally did a hard reset. After this, the watch still couldn't see any WiFi networks when I attempted to add one. Same result after restarting and trying again. I tried the "Sync via Wi-Fi?" option from Garmin Express for Windoze (GE). Not only did this not work, but it also caused GE to lose connection with the watch entirely (I did this twice to see if it was reproducible). After this, I reconnected and tried the "Find Networks" option in Utilities and while the FR245 found multiple WiFi networks, and I was able to add one, the resulting message from GE immediately afterwards for the 6X was "Your device did not find any networks."
