      Hi there,

      I happen to find some strange entries in my logs. I’m not sure, if they are MM2 related, but perhaps someone can Point me in the right direction.
      I’m running MM2 (latest) on a raspberry Pi 3 model B (Hardware BCM2835, Revision a02082) and seemingly the WiFi disconnects on a regular base (sometimes around an hour, sometimes 20min) and at times won’t reconnect:

        @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!

          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.

              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?

                Have you?

                Disable WiFi Power Save

                Disable power saving

                For Raspberry Pi 3
                Edit /etc/network/interfaces

                sudo nano /etc/network/interfaces
                Add the following line under the wlan0 section

                wireless-power off
                Reboot your PI

                sudo reboot

                Create a working config
                How to add modules

                  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.
