I've setup a RaspberryPi 3 using a minimum OS like raspberrypi-ua-netinst (preset:server) but also would like to enjoy the onboard wifi-adapter. Unfortunately I can't enter the credentials in the installer-config.txt but would like to add them later. The point is, that the folder:
/etc/wpa_supplicant/
and the config wpa_supplicant.conf doesn't exist in any case.
Does anybody know how to set up wifi, to get wifi working using the common way via the config to enter the credentials?
I don't think you have wpa_supplicant installed yet. Is it included in the minimal image? Try to update your repositories and install wpa_supplicant:
sudo apt-get update
sudo apt-get install wpasupplicant
Next, edit the wpa_supplicant file which should now be present:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
Add your network details at the end of that file:
network={
ssid="yourwifiname"
psk="yourwifipass"
}
Save the file using CTRL+x (confirm with y) and restart the wpa interface:
sudo wpa_cli reconfigure
Then check if you are connected to your network:
ifconfig wlan0
It's possible to specify the credentials since raspberrypi-ua-netinst v1.2.1.
Just add this to an installer-config.txt on the SD card:
ifname=wlan0
wlan_ssid=changeme
wlan_psk=changeme
All that information is in the README.md of the repository and shown on GitHub.
Otherwise, you can create the directory and the file by yourself.
