I updated my FR945 last saturday with the GPS 2.90 software (I think it was) and today after completing an activity and synchronising via Wifi (not ) I got the old " Wifi 0500 error code" again. This one was solved a few months ago and worked fine the last months. Nothing on my side (wifi, network etc.) has changed so I suspect it is the FR945 software. I believe it was something like wifi networks with a WPA2 key?
