Hello everybody,
i try with my best school english from 20 years ago. 
I decided to change from DDWRT to OWRT because of the newer linux kernel and maybe a working VLAN Configuration. But after the installation i found out that "Overide Mac Adress" for my Wan Port doesnt work, so i asked the internet an found this page.
I tryed to change the wan mac adress like in this descripion an if i used just the terminal its works, but it doesnt work with the script. Maybe you have an idea ...

If i enter the commands by hand it works fine.

I copied the script and make ist executable by typing chmod +x /etc/init.d/clonemac and enabled ist like in the description. but it doesnt change my wan mac adress, and i cannot connect to the internet.
Under system Startup i see the script, but it is disabled and when i try to start by /etc/init.d/clonemac start it doesnt work.
Only when i copy the commands to terminal the wan mac adress is changed.
you may have an idea ?
thank you very much,
david
