Got a Pi 3 which will always use ethernet, so trying to figure out how to disable the WiFi such that it does not even turn on after a reboot.
If I do an
ifconfig I see the
wlan0 device. I can do
ifconfig wlan0 down but it will come back up again after a reboot.
I tried commenting out anything about
/etc/network/interfaces but that has not made a difference.
eth0 is not commented out so it can be used.
