Hi,
Yes the dropouts can be caused because you have a very first production firmware on the device.
Please connect your uTrack24 to a wifi router, connect your computer to the same router, and connect Android or iOS device using wifi to the same router. Start the Fing application on your mobile which will tell you the IP address of your device.
Type that IP address to your computer webbrowser (Chrome, Firefox, Safari preferred) then use the 4064 bcd file to update.
