Explanation

To connect this PLC with your Wi-Fi network, you must modify the wpa_supplicant file inside the Raspberry:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

And you must configure the file with the configuration parameters of the Wi-Fi network (it may change depending on the specific configuration of each case):

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=GB

network={
ssid="NETWORK SSID"
psk="NETWORK PASSWORD"
key_mgmt=WPA-PSK
}

And that is all, after that you must restart the networking services to apply the changes:

sudo service networking restart

Or you can reboot the system to apply the changes:

sudo reboot
