Hi,


How can you tell that it has no effect?


See `man nm-settings`, or

$ nmcli connection edit $WIFI_CONNECTION
> describe wifi.mac-address-randomization



Verify the setting with
$ nmcli connection show $WIFI_CONNECTION



Setting default values in /etc/NetworkManager/NetworkManager.conf would
work, for that you need to leave the per-connection value at "default".
After editing the connection, you must always reload with `killall
-SIGHUP NetworkManager`.



mac-address-randomization requires support by Hardware and wpa-
supplicant. On Fedora23 I get a failure and the logfile reads:

  device (wlp3s0): Activation: (wifi) couldn't build wireless configuration: 
802-11-wireless: cannot enable mac-randomization due to missing supplicant 
support
