Configuring IP address and wireless network

To have a networking configuration, we need to assign an IP address to our device in order to be involved in the network.

Enter the following command:

sudo nano etc/network/interfaces

In the following configuration file, called interface, we explain what we need to add to the file so that we can connect our Raspberry Pi Zero to the Wi-Fi network for the Wlan0 connection.

We start the file configuration; it means the beginning of the file:

auto lo 

We configure the Ethernet device loopback for the local host and start up the DHCP server:

iface lo inet loopback 
iface eth0 inet dhcp 

Allow the configuration of the wlan0 for Wi-Fi connection:

allow-hotplug wlan0 
auto wlan0

We start up the DHCP server for the Wi-Fi connection and input the name of your ssid and the password. We need to type ssid and password parameters of your Wi-Fi network:

iface wlan0 inet dhcp 
        wpa-ssid "ssid" 
        wpa-psk "password"
