@dc42 said in Cannot get WIFI to work on a new Duet3D WIFI:

I am surprised that adding those commands makes any difference, because the M552 commands get deferred until config.g has completed. Or at least, that's what is supposed to happen. Are you sure it still doesn't work with just M552 S1 in config.g?

I removed the commands and just have M552 S1 now and it does still connect. I guess the M552 S-1 followed by M552 S0 was only needed after the firmware upgrade.

Thank you.
