Hi Lemming_ ,
I suggest you to use systemd for creating and managing the services (Instead of init.d)
Try by running the following commands:
root@galileo:~# systemctl kill wpa_supplicant.service root@galileo:~# systemctl mask wpa_supplicant.service
systemctl kill / stop / disable wpa_supplicant.service
in the shell; or adding it to the startscript did not work for me.
Masking the service did it! I runned your second command once only. And this annoying wpa_supplicant was gone after system start. Thank you CMata_Intel !!!
My interfaces are up and running. Like a lighthouse when the the sun goes down, my wlan-stick starts to send his beacons with flaring rim on system boot
By habit it stored the startupScript in the init.d folder.
