WiFi once lost never reconnects



  • Is it considered normal behavior with current firmware that once WiFi is lost it will never reconnect? Such as if the router is rebooted. I find the only way I can communicate with Duet after it loses the wireless connection is to reboot the board. It never attempts to reconnect.



  • @3dmntbighker Duet will retry twice (in short succession) and then give up. @dc42 is considering to change this (or make configurable) in the next/a future version of the firmware.



  • Thanks, I hope it gets changed. A lot of people have enough issues with ISP's and such that router reboots are all too frequent.



  • @dc42 until you implement a more complex solution, can't you simply reboot the wifi module on connection lost (if the printer is configured as STA)?

    WiFi Router reboot is not the only use case. I often experience losing one browser connection (Android tablet) and keeping another (Chrome on Win10) during long prints. I'd hate to risk them both. Therefore, perhaps some form of individual connection retry/reset would be better.

    By the way...

    Evidence points to the "hang up" being in the Duet. No amount of browser reset, cache reset, reboot, etc, etc, etc. on the tablet has ever allowed the Tablet-to-Duet session to reconnect. Once the print finishes, a Duet M999 or power cycle always allows a (re-) connect from the tablet.

Looks like your connection to Duet3D was lost, please wait while we try to reconnect.
