@droftarts I am sending it via USB from SerialTools on MacOS, so that definitely makes sense! I hadn't thought of that.
Thank you!

Hi! I have configured/set-up about 10 different Duet2wifi boards in the last year or so and occasionally I get a board that when I try to set up a network name and password using the M589 command, I type the line and hit enter and nothing happens, no error, no OK message. I then have to retype it numerous times until it just finally works. Because I am running through the same process on each board and this only happens from time to time I am not sure what the issue is or how to resolve it. Has anyone else run into this issue?

Thanks!
