I think this problem could possibly be because of some type of "class" conflict. I have absolutely no clue though, just a guess.2.
Now, I wan't to change my mac address to 01:00:5E:00:00:01.
By the same command and i get the same error message.
But if I change it to 00:00:00:00:00:01 --> than is their no problem.
So if anyone can help me by this questions, plz let me know.
