Yo tambien lo tengo y he encontrado esto:
"well : I have done it -- it just took me 5 minutes
- pls dont mind -- But did any one of u tried to understand what i am trying to ask .Changing MAC Id is not a big thing man. u really need to do that if ur stuck thorugh a MAC Filter on Routers etc. So its nothing very BIG i was talking abt. may be u guyz have never striked a mass level Network where these Bondages exist. Plus MAC Add change is first step of Spoofing mechanisms.
secondly.. May i know what Bios r u talking abt -- ?? the Firmware of the Device
-- well kwebb ur just thinking it too Deeply -- If u dont know the Process at all -- Pls dont make discussions Worse confused. I can not Put off the MAC Filtering OFF cos its my ISP who has this Feature so i have to Live with it.
---Now the Solution ---
In my case -- i just had to goto :-
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0008
On the Right Side -- Create a String Value named "NetworkAddress" & put in the new MAC Address in running Digits eg :-000EF6178D65
& Reboot..
in a Cmd Prompt -- ipconfig /all & see if ur MAC address is changed ..
---------------------------
Well this just took me 5 minuted to Figure out. The Registry entries may be different for other Hardware. Anyways Good Luck for future people who may want this to be done "
