ath0 mac address wrong


Hi all, when I boot my computer my wifi card has the correct mac address:

ifconfig | grep -a HW
ath0 Link encap:Ethernet HWaddr 00:15:AF:67:96:24
wifi0 Link encap:UNSPEC HWaddr 00-15-AF-67-96-24-00-00-00-00-00-00-00-00-00-00

Now if I destroy and put ath0 in monitor mode the following happens:

ifconfig ath0 down
wlanconfig ath0 destroy
wlanconfig ath0 create wlandev wifi0 wlanmode monitor
ifconfig | grep -a HW
ath0 Link encap:UNSPEC HWaddr 06-15-AF-67-96-24-40-E2-00-00-00-00-00-00-00-00
wifi0 Link encap:UNSPEC HWaddr 00-15-AF-67-96-24-00-00-00-00-00-00-00-00-00-00

In managed mode it shows this:
ath0 Link encap:Ethernet HWaddr 06:15:AF:67:96:24
wifi0 Link encap:UNSPEC HWaddr 00-15-AF-67-96-24-00-00-00-00-00-00-00-00-00-00

Notice the weird unholyness, basically it works at boot time and the addy is correct then when I make a change, the mac address is entirely different!

Any ideas on fixing this? I've tried macchanger (works until I reboot) and ifconfig ath0 hw ether blah, also works till I reboot. It's a real pain as I can't connect to anything.

Got it...

It needed the -bssid flag at the end of wlanconfig, weird. I'm certain I havent always had to put that :S.
