2. Check if WiFi network is configured and does not conflict with the LAN

• Click on the next tab (which can be your WiFi Access Point name)

ping   192.168.4.78

and check the result. Check another address in case no connection.

Change myCNC controller IP address if no connection. Connect myCNC controller to the Host by USB cable and run Minicom software

sudo   minicom   -D  /dev/ttyUSB0

In the minicom software run command to change IP address

#SLA  192  168  4  78

and check the reply

IP:  192.168.004.078

Exit from Minicom (CTRL-A Q), repeat the pinging step to ping the board
