Introduction
Raspberry Pi PLC Â devices has Wi-Fi wireless connectivity by default.Â
It uses the two most common frequencies: 2.4GHz and 5GHz. It also uses the IEEE 802.11.b/g/n/ac bands. And, to connect them to the Wi-Fi network, you have to follow some specific steps.Â
Requirements
The key points to consider are as follows:Â
- Raspberry Pi PLC
- PLC access: shh. A tutorial on how to access the device via Linux or Windows can be found in the Raspberry PLC User Guide.

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
