Hi, I have intel eeupdate.exe which has worked for me perfectly in getting my onboard wired intel 82566MM 10/100/1000 lan adaptor a new mac address. What is the method / utility of doing the same to an Intel 4965AGN which is the other network card (the wireless one) on my laptop. Really keen for an answer on this have been searching for days. Regards, Matthew PS it is a hardware eeprom flash / update utility that I'm looking for. NOT A WINDOWS override spoofing fix - as I already know about this and it just isn't what I'm looking for.
