      Was there a bug in 1.19 that is fixed in 1.20 ?

      i read the thread about 1.20 some are also reporting connection problems,

            i see my wifi strength is not great -69dBm, but i dont think this has anything to do with it.
            For example if i upload file it just works fine even with really big ones,

              i missed the number of AJAX retries setting, it was set to 1, changed to 5 and it is a bit better,
              But i still get disconnects.
              Maybe i set it to a really high number.
              But it doesnt really fix the problem i think it just makes it workable

                oke with AJAX retries set to 50 i was connected for 5 minutes. but then i get the AJAx error
                and i could not reconnect again it looks like web server is just down . My browser gives me this error : ERR_CONNECTION_RESET

                When i send ping to the Duet it does reply so it does have a wifi connection.

                  is there a special procedure to go back to the old firmware ?
                  i think the last working version (for me) was :

                  • DuetWifiFirmware-1.17e
                  • Duetwebcontrol-1.14a
                  • DuetWifiServer-1.03-ch

                    Have you tried both versions 1.20 and 1.20+1 of DuetWiFiFirmware?

                      i download this version : https://github.com/dc42/RepRapFirmware/releases/
                      thats 1.20
                      Where can i get the 1.20+1 ?

                      I prefer to go for the latest version that didnt have the disconnect problems .

                      i see on this board users who have this 1.20+1 version and the are also reporting disconnects.

                      I dont have a panel due connected so my only option to print is with the webinterface.

                          i installed the old firmware, and untill now i didnt see any Ajax erros .

                          it looks like there is a bug in the 1.19 and later firmware. or my board is broken.

                          would be nice if this is fixed so i can also enjoy the new features.
