Hi Adrian,

Maybe I don't understand you, but this summarizes what I think I understood:
Changing the wireless NIC's MAC is not possible. Only in some cases, but
those cases are exceptions and shouldn't exist.

I don't understand how this is pushing me further to solve my problem. As I
mentioned I'm now changing the MAC of the wired NIC to that one of the
wireless NIC. So your remarks don't apply to this situation, I think.
Am I right?

By the way: Do you think the configuration examples (in handbook and manpage)
I provided earlier in this thread are misleading and should be changed?
