thanks, I updated to 1.19, sent M588 S"*" and yes, it forgot my network settings. Then go back to 1.18 due to poor wifi signal in 1.19 and constant conection loses but again it is necessary to go to DuetWifi with my mobile and set it up for my network every time i reboot the board 😞
Even I pressed the erase button and do Fallback procedure #3 but no luck.
Thanks for your help
