How can I disable wlan by default in the network manager?

  • 772

I use Ubuntu Mate 16.04. I do not use wlan usually, but if I need it, I want wlan to be available. To disable wlan, I deselect “Enable Wi-Fi” in the network manager's applet. This seems to succesfully turn of wlan, but doesn't survive a reboot. How can I permanently deselect the “Enable Wi-Fi” option such that (a) that configuration survives a reboot and (b) I can enable wlan through the network manager applet if needed?

  1. It is strange that disabled wifi doesn't survive reboots. It does here.

    You could use the rfkill, which is a "tool for enabling and disabling wireless devices". (see man rfkill for more info)

    To disable wifi, run sudo rfkill block wifi.

    To re-enable, run sudo rfkill unblock wifi.

    If all works as expected, just add rfkill block wifi to /etc/rc.local
