Had PiAware running reliably for around 6+ months on a Zero with wifi. As a safeguard a small script runs every 5 minutes, checks connection and, if down, reconnects.
Last couple of days suffered disconnects with no reconnection - as it is headless difficult to narrow down but syslog file suggests system still running.
Switched card to different Pi, connected fine on different IP, aircraft map showed activity then dropped.
Any suggestions as to what log file to check to see what problem might be?
Appreciate any comments,
