      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.

                                    Ill be away from the printer for about a week, but will updated to that new version you shared David as soon as I return.

                                      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.

                                        Updated to alpha1+1 - pretty much the same story for me unfortunately.
                                        The following log is right after a disconnect when idle. I restarted the wifi module with M552 on device.

                                          I've been leery of updating beyond 1.18.2 due to the frequent reports of WiFi issues. Today I decided to take the leap. The upgrade to 1.19.2 went well. Checking M122 my RSSI varied between -53 and -58 (the access point is one floor away in a wood framed house). I stayed connected from a web browser (Google Chrome from a Mac) for approximately 4 hours. During the middle of that 4 hour window was a single 90 minute print.

                                          All seemed good. Not posting to gloat - but just wanted to add some data points. My access point is an Asus router running the third party Asus-Merlin firmware.

                                            @JohnOCFII:

                                            My access point is an Asus router running the third party Asus-Merlin firmware.

                                            My setup is similar, albeit with the issues.
                                            I have an Asus AC3100 as my main router about 3m away, and an AC66U about 12m away as an access point both with same firmware version, both Merlins.
