Sorry but this feature is not supported on 12.x and later. The 5100 is only supported on 12.x and later drivers. You can find more information at http://www.intel.com/support/wireless/wlan/sb/CS-031081.htm,
hi ilenet thanks for reply
i knew that information before so i asked for earlier driver
i have the old driver it worked in toshiba with intel wireless 5100 agn before but didn't work in my current laptop (acer with same wireless card) i didn't know why
so i'm looking for old driver that may work with me
Laptop manufacturers often make changes to the wireless software and drivers. This could explain why Toshiba works and the Acer does not. There are also differences in how the manufacturer integrates the wireless adapter into the laptop. As I said before Intel does not support changing the MAC address on the wireless card. Why do you need to change the MAC address? Perhaps there is a workaround to your issue.
