Re: How can I clone a mac address on wlan0?

The way I'd debug this (without being a developer) is:

* get another laptop with say an ath card;
* put that interface into monitor mode;
* tcpdump -vveni wlan0 -y IEEE802_11_RADIO | grep -v Beacon

Then try associating to the access point and see what station MAC it's
sending in its packets.
