How do I reimage the Pi?
I have been working with my own setup and with FlightRadar24 on this problem. Please read their response to me this morningâŚ

I believe that I have traced the problem to the following from the system log of my modem / router: âStarted Unicast Maintenance Ranging - No Response received - T3 time-outâ
That command and activity out of the modem / router (which occurs periodically) causes the Pi to lose internet connectivity to the FR24 part of the software. It doesnât totally bonk FA from continuing to report aircraft activity however it does affect FA from continuing to report and update PiAware SkyAware. A Google of the Unicast Maintenance Ranging activity indicates
many people experience the same issue. At this point I am not sure what causes the lack of response or what to do about it. I have calls in to Spectrum techâŚ
The following is from my modem / router. Note the time stamps:

To get things to return to normal I have to reboot Pi.
This implies that dump1090-fa is no longer running. Perhaps you have a problem with the receiver dongle.
