NetworkManager changes WiFi MAC address

If your WiFi is managed by NetworkManager and it has random MAC address after reboot, you can disable it in /etc/NetworkManager/NetworkManager.conf:

[device]
wifi.scan-rand-mac-address=no

[connection]
# ethernet.cloned-mac-address=permanent
wifi.cloned-mac-address=permanent

[connection] section shouldn’t be necessary nor ethernet line (it is commented).
