      Edit: second disconnection, same print, reconnected after 2nd press of connect without having to cycle wifi module. Router showed it as not connect prior to using connect button.
      After it reconnected, a M122 showed Reconnections 1 (first time I've ever seen reconnections not be 0)

        @dc42:

        Thanks for that report. Net time it happens, please log on to your router and see whether it still shows the Duet as a connected client, and post the relevant bits of the M122 report again. The M122 says that the Duet is connected to the router, but I want to know whether the router agrees.

        Are you using a static IP address, or DHCP?

        This is a bit odd.

        Currently I can't load DWC.
        Pronterface shows connected to my network
        Router shows connected but access type is "wired"

        Edit:
        After running M552 S-1 and then M552 S1, the router now shows the Duet access type as "2.4G", as expected.

        I will keep an eye on this to see if it always changes to "wired" when the issues happen.

          I just upgraded to 1.19.2 and I see the same issues as described in callil's comment above.

          Does it help if I do Airtraces with my Mac? If yes, should I do this with 1.19.2 or should I upgrade to 1.20 beta?

          The interesting thing I am seeing is that the duett is still associated to the AP but it is not answering to pings.

            The next DuetWiFiServer release I do will be designed to work with 1.20beta1, or possibly a later 1.20 beta release.

              I upgraded anyway, it took a little longer until I was unable to use the connection.

              Fun thing is that I still see packet exchange between AP and duet:

              RSSI: -40 dBm
              TXPacketCount
              176423
              RXPacketCount
              20352

              a little later:

              TXPacketCount
              176799
              RXPacketCount
              20744

              I can also still access station stats of the duet:

              Are you able to turn of Powersave on the esp? I see in the stats that PS flag is set, I have seen numerous errors with Powersave on WiFi

                And this is tonight's error….

                This was loading DWC about 1 min after a fresh power up of the printer:
                Error reason: SyntaxError: JSON Parse error: Unterminated string

                Then after hitting refresh for the web browser I got a different error that I wasn't able to copy before it disappeared, but I think it ended in "invalid digits."

                after M552 S-1 and S1, this is the new error:
                Error reason: SyntaxError: JSON Parse error: Expected '}'

                EDIT:

                updated to all the latest firmwares from the edge GitHub, disconnects continue. That was expected, but just as an FYI for those following along.

                  Hey David,

                  Just checking in on the new firmware. I continue to have disconnects, but haven't done much or posted any further on them in the past few days.

                    I recall that some of you report that the WiFi is reliable when the printer is idle, but it disconnects a little while after printing starts, even though you are not using high microstepping. It occurs to me that this could be temperature-related. The WiFi module gets warm in normal use, and when the stepper drivers are generating heat as well it could be getting too hot to function properly. So please try the following:

                    • Monitor the CPU temperature in DWC until the point at which it disconnects. Is there a significant rise in temperature?
                    • Try cooling the Duet with a fan, if you don't already.

                      David,

                      Where in DWC can I see the board temp?

                      Thanks

                        on any page if you check the Temp area top left you will see an Extras label click it and the MCU temp will appears which you can add to the Line chart if you wish.

                          My Board is mounted above my delta, so bed heat has no effect. The board temp is low to mid 30's when no fan is used. (calibrated just yesterday its about 3 degrees below the PT100 temp)
                          Mine also disconnects while idle.

                              Over a couple different hour long prints the MCU temp stayed right around 34 C.

                                Please can those of you who are experiencing disconnect errors and are running DuetWiFiFirmware 1.20beta1 try changing the wifi firmware to version 1.20alpha1+1, which is available here: https://www.dropbox.com/s/u7vpp2wg4rlqs8l/DuetWiFiServer.bin?dl=1. Then let me know if you think it is better or worse.

                                            David, I juste realized that my WiFi signal strength is really low: -68dBm! I think I'm lucky it's working so well, despite such poor signal!

                                            I think I will order the new ESP module, with antenna.
