My Simulink model fails at the build stage when set up to run in external mode with communication over WiFi. I get an error stating that a .c file is missing from the WiFi101 library.
I did some digging and found that the library was restructured and the expected .c (socket_buffer.c) file has been removed. I tried to install the most recent version of the library that still had the file but ran into another error. The model builds, but I get an error that an IP address could not be assigned. The suggested cause of this is an outdated WiFi101 library...
Seems like a Catch 22. Anybody managed to get this working?

Simulink support package requires the WiFi 101 library to be a specific version - 0.14.3 . Type winopen(arduinoio.IDERoot) if you are in Windows and open the Arduino IDE. If not, move to the location and open Arduino IDE.
From the IDE itself, update the WiFi library to that specific version and this error will be gone.

It seems like the communication between MATLAB and Arduino was interrupted. I would recommend not moving the physical USB cable that connects Arduino to PC. Retry after putting the board into bootloader mode.
You can do this by double pressing the reset button. To confirm that the board is in bootloader mode, open Device Manager and check Ports, here you should see Arduino MKR1000 bootloader mode.
HTH,
