I am trying to change the MAC address of my wlan0 device, I tried with ifconfig wlan0 hw ether. I tried also macchanger, but after I changed it WiFi won't establish a connection. It sees the WiFi networks and prompts for the password, but it won't connect.
if i turn wlan0 in hotspot mode with nmcli dev wifi hotspot and then killall wpa_supplicant something reloads the WPA_SUPPLICANT and WiFi gets working.
is there a way to change MAC on boot time before loading the WPA_SUP.... ???
I apply part from dmesg with connection attempt:
