My rpi3B loses connection with the local area network quite often. At the same time the internet connectivity to flightaware work perfectly. I manually turned off the power-save with “sudo iw wlan0 set power_save off” and this apparently has kept the LAN connectivity for hours now.
The question where do I put this command (or others) to make this change permanent. I do not see it in the piaware-config file.
