    First step i would do, is a replacement with another power supply.
    Does it have enough power. At least 2.5A is recommened i guess!?

    I guess it is not related to the MM itself, its a Pi problem.

      @barnosch hmmm… Thanks! I just replaced the 1,5A with a 2A one as I lack a 2,5A one. I’ll Keep that in mind, though!

        the only “original” RaspPi3 powersupply they sell has 5V/2.5A
        But i guess a 2A is good to go.
        If the old one has some problems or drops the voltage from time to time, the issues you have can happen easily.
        Just try with the other one?
        You are using the internal Wifi or with a external USB-Wlan Dongle?

          For Raspberry Pi 3
          Edit /etc/network/interfaces

          Add the following line under the wlan0 section

          wireless-power off
          Reboot your PI

            Honestly I think this happens when you update the Pi…I don’t believe it’s MM doing this.

              Just a short information, after changing the powersupply to 5V/2A instead 5V/1,5A it now seems stable. I now only get a rekeying-message every 10mins in the syslog, which I suppose is my FritzBox. :)

              I’m using the internal WiFi - apparently withou power saving off. But seems OK.

                @binderth I found that 2A isn’t enough for the pi3, when under heavy load it would fail. The raspberry 2,5A power unit is highly recommended.
