Hello everyone.
First of all: Please, sorry about my poor English. And please, sorry if this is not the right place for this topic.

I'm doing some tests changing the mac address of wlan0, and restoring the original (permanent/hardware) mac. I have problems with this one.
If I turn on the N900 and look my mac address:

Code:

xterm
root
ifconfig wlan0

I can see a mac address like

Code:

A0:4E:04:XX:XX:XX (Nokia Corporation)

But, if I restart wl12xx module and look mac address again:

Code:

ifconfig wlan0 down
modprobe -r wl12xx
modprobe wl12xx
ifconfig wlan0 up
ifconfig wlan0

Mac address is like this:

Code:

00:1F:DF:XX:XX:XX (Nokia Danmark A/S)

So my question is:
What is happening? Is this a troubble with my N900, and only mine? Does it happen to you?
Anyway, if I changed mac address with

Code:

ifconfig wlan0 hw ether xx:xx:xx:xx:xx:xx

how could I get permanent mac address?
I can do it in my PC with

Code:

macchanger --permanent wlan0

but not in armel version, because there is not "--permanent" option.

Thank you very much!
