    Hello when ever i try to run my mac_changer code it gives me this error

    wlan0: ERROR while getting interface flags: No such device

    SIOCSIFHWADDR: No such device

    wlan0: ERROR while getting interface flags: No such device

    here is my code
    import subprocess

    subprocess.call(“ifconfig wlan0 down”, shell=True)
    subprocess.call(“ifconfig wlan0 hw ether 00:11:22:33:44:66”, shell=True)
    subprocess.call(“ifconfig wlan0 up”, shell=True)

    No I don’t
    Actually when I also type ifconfig there is no wlan showing ( it was showing but when I did the code it disappeared)

    Hi!
    Well, if you don’t have a wireless adapter then there won’t be any wlan0 interface. In such case you can try the code with the eth0 interface but it will lose internet connection after changing the mac address, that’s normal because it’s a virtual interface but if the code works then you cna move on.

    Greetings!

    Hi!

    No, it looks you have some typos in your code, actually you are missing some blank spaces. Can you share your code please?

    Thanks!
    Diego
