Is "/dev/tty.usbmodemFA131" the same as "Duet?"

If you unplug the Duet does that device dissapear?

@phaedrux “Duet” never showed up. “Communication Device” did, however. Still, after two days of misery, I couldn’t get the wifi to work. I never saw DWC no matter what I tried. My house is 5G. There’s no place for a 2.4G system here. Thanks for replying.

@fcwilt There's a modem in the house, and an extender. Overall, we are 5G everywhere. Getting a 2.4G system to work in this environment proved to be impossible. Duets instructions are overwhelming. The info on backing up the card that came with the board is overwhelming. For what I paid for this board, it should have installed itself. Duet is years behind. Thanks for replying.

Why was 2.4G a problem? It has better range than 5G.

@fcwilt I was using a MacBook to power the board. I was also sending the MacBook’s screen to a 27” monitor. So I could see the instructions, and Serialtools. I had a ferrite ring on the usb cable to the board. From the moment I first powered the board the far left led was constantly blinking. I was trying to install my ssid and password to a 2.4G network coming from an extender model six feet away. I was having a heck of a time typing in the codes for some reason. This went on for a couple of hours. Then I realized that my MacBook was overheating, which was messing with the keyboard. That’s when I moved everything to a mac pro. But that machine is connected to the 5G network. Serialtools would not show me the board, only the Mac’s gear. So I couldn’t do anything because both of my computers were down.

@corlissmedia duet boards don't support 5GHz. 2.4GHz only!

@jay_s_uk I know. I read that in the instructions.

@phaedrux I did use that method to see what would remain. There is a bit of a Sherlock in me, but only a bit.

@corlissmedia The 2.4G vs 5G really shouldn't be a problem. Almost every router made can (and by default does) treat them as a single network when supplying a local network address via DHCP.

What you are describing is identifying the USB data stream - which on different hardware (i.e. macos) will have different names, and that is what serialtools is talking to. You only need that USB data stream to use serialtools and set the SSID and password up and then the wifi will connect to your local network which should then work as documented by Duet3d.

Whether computers are connected to 2.4G or 5G they should find the Duet's wifi.

@corlissmedia SerialTools is a bit finicky about input; you have to get the command right, without pressing delete or cursor keys. I think it sends each character to the Duet as you type them, rather than when you press return. If you navigate away from SerialTools to another application, and then back, in the middle of writing the command, it won't work. You should get an 'ok' when a command goes through correctly.

Also, make sure you're using straight quotes, eg " rather than curly quotes, eg ”

@corlissmedia In response to your first question, yes, "/dev/tty.usbmodemFA131" is probably your Duet. Only Windows will show "Duet", and only when the drivers have been installed. See the macOS tab of https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#install-drivers

@markz Thank you, that was helpful. Maybe the instructions, when one is using the MacOS window could reflect that (the picture didn't).

How do I delete an incorrect SSID?

Or is that accomplished if I add another address?

@droftarts thanks for the clarification. very helpful.
