I have an Intel 1000 BGN Wi-Fi card and I tried to set its MAC address to 00:00:de:ad:be:ef, but this didn't work:

[root@localhost .]# ifconfig wlan0 hw ether 00:00:de:ad:be:ef
SIOCSIFHWADDR: Cannot assign requested address

But setting it to 00:26:de:ad:be:ef worked. Do you know where the problem is?

On Windows I wasn't able even to change the MAC address; it just didn't change when I changed registry entries, etc.

What is the original mac address of the adapter? –  ott-- Jul 14 '12 at 21:08
    
00:26:03:xx:xx:xx <-- in every Intel Wifi card it starts with 00:26... –  djmati11 Jul 15 '12 at 7:35
    
Also, I've read about that you cannot change to MAC that doesn't start with 00:26, but I thought it is on Windows. –  djmati11 Jul 15 '12 at 7:35

Every "normal" LAN or WLAN driver can change the whole src-address, this looks like a restriction. You should be able to find the location of the 00 26 with a hex editor. Make a copy of the driver and change it. –  ott-- Jul 15 '12 at 12:09
