Raspberry PI Zero W WiFi activation and configuration

Two possibilities to activate the Wifi Raspberry Pi Zero W :

1. Without screen :

1.1. Install the OS, once done, do not put the Micro SD card in the Raspberry Pi Zero W yet.

1.2. Via a File Explorer, go to your Micro SD card and create a file named wpa_supplicant.conf containing the following code :

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

ssid=”Your network SSID”
psk=”Your WPA/WPA2 security key”

The data entered in this file are the ones you use to connect to your home Wifi network. Depending on the security implemented in your wireless network, the key_mgmt can be: WPA_PSK or WPA2-PSK (these are the two most common) or WPA-EAP (often in business).

Save this file and close it.

1.3. Do the same to enable SSH by following this tutorial .

1.4. Insert your Micro SD card into the Raspberry Pi Zero W and start it.

If all went well, your Raspberry Pi Zero W will connect to your home Wifi network.

All you have to do is find his IP and  connect to it with SSH .

2. With a screen and keyboard connected to your Raspberry Pi Zero W, proceed as follows :

2.1. Find his IP and  connect to it with SSH.

2.2. Type the following command : sudo nano /etc/network/interfaces

2.3. Go to the end of this file and add the following code :

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

To save tap ctrl+o and ENTER, then leave the editor type ctrl+x.

2.4. Optional : To scan all visible and available Wifi networks use the following command : sudo iwlist wlan0 scan

2.5. Type the following command : sudo nano /etc/wpa_supplicant/wpa_supplicant.conf.

Go to the end of this file and add the following code:


Adapt the “country” parameter according to your region: FR = France, BE = Belgium etc. Or use the commandsudo raspi-config (see below*)

To save type ctrl+o and ENTER, then leave the editor type ctrl+x

* To adapt automatically the “country” parameter according to your region, type the command sudo raspi-config , select “Localisation Options” press , tape ENTER, then select “Change Wi-fi Country” and select your country.

Once your country is selected, type ENTER, again ENTER, TAB twice to select Finish, and ENTER one last time.
