      Hi Community, hab mein MagicMirror neu aufgesetzt. Unter anderem hab ich Telegram Modul drin.
      Als Betriebssystem musste ich Buster für mein Pi nehmen. Solange der Raspi am Netzwerkkabel angeschlossen ist läuft alles gut. Wenn ich aber über den Wlanadapter mit Inet verbinde hab ich verschiedene Fehler.
      Das Sagt mir mein Telegrambot.

      Ich bin aus dem Tiefschlaf aufgewacht.
      Error: EFATAL
      Description: No internet?
      

      Oder ich hatte auch

      [Warning] An error has occurred!
      Error:502
      Description:Bad Getaway
      

      Meistens aber die erste Fehlermeldung. Und der News Modul zeigt Meldung kein Internet.
      Ich glaube mein Wlanadapter geht in den Schlafmodus.
      Wenn ich iwconfig eingebe. Steht die Meldung Powermanagement off
      Das hab ich auch noch probiert

      sudo nano /etc/network/interfaces
      allow-hotplug wlan0
      iface wlan0 inet manual
      post-up iw wlan0 set power_save off
      

      Jetzt läuft der MMirror länger aber steigt trotzdem mal aus 
      Ich hab WlanAdapter von Edimax , also hab ich auch das probiert

      sudo nano /etc/modprobe.d/8192cu.conf
      options 8192cu rtw_power_mgnt=0 rtw_enusbss=0
      

      Fehler ist immer noch da. Jetzt weiss ich nicht mehr was ich machen mus :(

        Leider ist meine Deutsche nicht so gut.

        RPI’s WLAN sometimes go to sleep and never wakes automatically.
        Maybe this would be help.

        > sudo iw dev wlan0 set power_save off
        

        wlan0 might be your WLAN adapter name… It might be different by your setup.

          I understand that, but how do I make sure it doesn’t fall asleep

          
          that shows my iwconfig

                  Check your previous trial with this.

                  sudo nano /etc/modprobe.d/8192cu.conf
                  options 8192cu rtw_power_mgnt=0 rtw_enusbss=1 rtw_ips_mode=1

                      I know this site and I tried the first one.
                      But I have Buster and it says something about Jessy and Stretch, what goes with Buster
