I am trying to change my MAC address via

in linux mint 18. I use :

ifconfig wlp3s0 down     //must use, to avoid error "interface up"
macchanger -rb wlp3s0
ifconfig wlp3s0 up

The MAC address change successfully, but I have no internet after changing it, if I choose to connect to the same network from the panel (reconnect to the network), it reconnect and I have the internet back, but the MAC return to the default address. anyone faced this problem or know a fix ?
