I keep getting notices from FlightAware that my site is down (RPIi 3B, active cooling, Flightaware Pro Stick Plus, 5db antenna) and is not sending data. I checked the config.txt file and the SSID for my wifi network had been changed, to MyWifiNetwork and a seemingly random password. I re-imaged the SD card with a fresh Piaware image and edited the config.txt to connect to Wifi. All was fine for a few days, and the Piaware site is down again-and the config.txt file has been changed back to MyWifiNetwork.
If I connect the RPi to Ethernet it works immediately, but I do not have ethernet anywhere near where the Piaware unit is installed.
I am suspecting SD card corruption, but is there any other likely culprit? The SD Card is a Sandisk Extreme 32GB.
