Ich habe immer wieder Schwierigkeiten mit meinen WLA-Zugang zum Raspi, wenn der Raspi weiter weg von der Fritzbox steht.
Meine Vermutung ist, dass sich das WLAN nach einiger Zeit abschaltet.
$ iw wlan0 get power_save
Power save: onIn der crontab für jedes reboot powersave ausschalten
$ sudo crontab -e
@reboot /usr/sbin/iw wlan0 set power_save off > /home/wnf/power_save_log.txt 2>&1$ iw wlan0 get power_save
Power save: offMake "iw wlan0 set power_save off" permanent
Leider hat das nicht geholfen, nach zwei Tagen wurde die WLAN-Verbindung wieder getrennt:
