Edit /etc/NetworkManager/NetworkManager.conf

Add a line to the [main] section like

no-auto-default=xx:xx:xx:xx:xx (obviously replacing the x's with the
mac-address of your mesh device.)

This does not stop NM from managing your device, but does stop it from
auto-connecting the device.  You would still be able to go into NM and
manually enable the mesh network.   If you want NM to completely leave
the device alone you can go one more step.

Also in /etc/NetworkManager/NetworkManager.conf

change the plugins line to


Then add a section that looks like this.

unmanaged-devices=mac:xx:xx:xx:xx:xx:xx (Where X's are the mac address
of the device you want to ignore)

Hope that helps, let me know if you have further questions.
