      I'm not sure if this is the appropriate category, or not, I can start a new thread elsewhere if its not.

      I have a fairly new Duet 3 Mini 5+ (about a month old), and when I reset or power off the board I have to reboot it 3-4 times before I can get access to DWC. The board shows up as connected to my network, but going to the IP address returns an "unable to connect" message.

      I am running RepRapFirmware 3.2.2 (2021-02-11), and Duet Wifi Server 1.25beta0 (if there is an updated wifi server ver I have not been able to find it easily)

      Once things do get connected, the web interface works great, as does the printer generally.

      Any ideas where to begin troubleshooting this? I don't even know if the issue is software, hardware, or my network.

        The next time it's doing this would you be able to connect via USB terminal and send M122 and see what it says about the SD card? Also send M21 to see if it can reach the SD card.

            Just to be clear those results are from when you were having trouble loading DWC?

              @phaedrux That is correct, those were done while the board would not connect to wifi. Down near the bottom you can see the the wifi IP address is 255.255.255.255.

              Here is the output once it does connect:

              It doesn't make any sense, all I do is reboot another two times, and it just connects no problem.

                @patrickwjoyce said in DWC is requiring multiple restarts to connect:

                WiFi firmware version 1.25beta0

                When you are connected can you please try uploading this zip file to the system tab in DWC? This should reflash the firmwares. Check M122 again after to see if the wifi firmware is 1.25 without the beta0.

                  I had a simmilar behavior which seemed to be fixed by making sure to include the SSID within the M552 command.

                    @phaedrux The non-beta version of the wifi server appears to have solved the problem of requiring multiple reboots to connect to wifi. Thank you very much.

                    I will note that I spent a good amount of time, last month, searching for a non-beta wifi server firmware, but had no success finding it. I am fairly familar with Github, so I don't know why it was such a challenge to find that particular item. What is the best way to find specific wifi server updates?

                      I do have the SSID entered via the M552 command, but oddly enough, only one of my SSIDs would actually connect properly. Over the course of my trouble shooting I tried my 3 different SSIDs but the only one that would connect was my super isolated IOT subnet. I'm wondering if the new wifi server version might fix that issue as well.
