      @zBeeble said in Duet2 wifi stuck repeating Wifi Error.:

      as generating a line every so often ... printer on or not.

      But the machine is connected to the home server ... which is always on. I'm using minicom ... which is set to log all traffic

      Reply

      Those "already 4 conns" should be normal, especially when there are multiple clients with the web interface open.

        So... been printing OK... for awhile. Just started acting up today again. Oddly, the serial output is "chunky" .... and incomplete. One recent query:

          Notably, on one output not shown, "slowest loop" was around 146ms.

            I've turned on the debugging for 14 and 1 (wifi and network). Lots of chatter, but the printer is definitely acting up. The serial is no longer chunky, but at one point, I disconnected the serial ... which would reset the driver on the server.... and probably the duet, too.

            m111 and chatter look like:

              Have you tried updating to 3.5.2 yet? Or the 3.6 alpha release? I think the beta is upcoming as well.

                The printer was idle, so I shut off the constant network chatter. wifi debug was still on (as it's fairly quiet). During the idle day, it said this:

                Now.... 2 computers look at the web server and the web server is on an RFC 1918 address behind NAT ... so not general internet exposed.

                  I'm a little bit upgrade adverse ... you can convince me, but equally, I don't believe this is upgrade related.

                    OOB ... looking at your debug message ... you could probably significantly cut binary size by cutting /home/renz/Projects from the path of all debug messages --- ie: cut to the root of the project.

                      OK. Now it's full-on inaccessible.

                      Lots of these lines scrolling on the console.

                        And just to be clear, two local computers are pointing at it and no network traffic (as expected) is coming from the router for it.

                          This is the log from the first few glitches above (posted here) through starting a new print and then it glitching hard:
