at the end i've known that windows 7 have limitition for mac address
now i want to know a way to break this limitition or method to change it
The only reason you might have to change a mac address is if the router to which you are connecting is operating mac address filtering. Is the router to which you are connecting under your control? If so has it got mac adderess filtering enabled?
If you don't control the router, we can not help you further. It seems you're trying to gain access to service not intended for you. If I am wrong, please take it up with the Administrator of the router. He or she can add your current mac address to the whitelist. We do not offer help with spoofs, cracking or hacking here. Thanks.
If you need any further help with this problem you need to tell us exactly what the situation is - who the router belongs to, what sort of access you have and especially whether or not your access is with the full knowledge and permission of whoever owns it. This is necessary not only because it enables us to give accurate advice but also to ensure that we are not supporting some illegal or hacking activity. (I'm not suggesting that you are but the circumstances you describe do sound a little strange).
