Wifi Connections Without Passwords
-
I couldn't connect to a wifi connection that did not have a password. It would see and even remember the wifi connection name but it wouldn't actually connect. I tried (p"") and even just network name without (p). It never output an IP address. This is what I ran into when I took my 3d printer to teach that lithophane class. Luckily I had a paneldue. So the actual class went fine.

Thanks for the report. I can test this, however most WiFi networks without a password require some a login after connection, which would be a problem.
Your other option in these situations is to run the Duet in access point mode, then you can connect to it from a laptop, tablet etc.. This is implemented in the 1.20 beta firmware.
