[PROBLEM] wpa_suplicant not started automatically

[luisrosety]

Hi all,
I have been struggling setting up Moode 6.4 on my Raspberry Zero W
The problem is that WiFi is not connected and I have tried creating a wpa_supplicant.conf but it does not fix it.
I tried to configure with

Code:

$ sudo raspi-config

But when trying to access the wireless configuration it throws an error message "Could not communicate with wpa_supplicant"
Then I tried

Code:

$ wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0

And then it connects to wireless!
There is something avoiding wpa_supplicant to start on boot but it does work when manually launching it.
Any help?
Thanks
Luis
