I`m helping a friend with setting up his Profimaker3D Printer with a new Duet2 WiFi. When I configure the WiFi settings with M587 S"" P"" for my WiFi network it works fine. Now I have finished setting up the printer, and would set up the WiFi setting ready for his WiFi setting. But now the setting won't save, I can not change the WiFi settings.
Can you only configure the WiFi settings if you can connect to the WiFi?
Or is there a step for changing the WiFi settings I have over looked?

The machine is huge, I would like to be sure so I don't neet to take it back and forth I hope somebody can help
