  • Patel,

    We have a long and ongoing discussion for this issue here: https://www.duet3d.com/forum/thread.php?id=2628

    I think it would be more beneficial for everyone if you joined that conversation rather than having two separate threads.

    Thanks!



  • If you haven't already, would recommend reading this:

    https://www.duet3d.com/wiki/WiFi_disconnections_and_AJAX_timeout_errors

    Your -77dBm signal strength is rather weak, and indicates something is blocking the signal from your router or the router is far from the Duet.



  • my printer near router is see -35dBm signal strength. still I getting AJAX error.



  • I am still getting error. Any one know. how about I use panel touch to the my duet wifi. I can resolve this problem. I am tried to resetting.


  • administrators

    If you get an AJAX error and you can't reconnect, try sending M552 S0 followed by M552 S1 from PanelDue. This forces a disconnect and reconnect form the access point. After a few seconds, you should get a message on the PanelDue saying whether the reconnect was successful or not. Then try reconnecting the browser again.

    If that doesn't work, try M552 S-1 followed by M552 S1 instead.

    I have a new build of DuetWiFiServer under development, which I hope will either fix these issues or at least make the cause easier to track down.



  • today morning i connect duet WIFI it works but 12.21.45pm start and 12.44.16pm disconnected, AJAX ERROR has been report
    also, you mention new build of DuetWiFiServer under development, please can you explain more detail about step to update
