Changing your hardware address can be a pain in the Microsoft world. Because of some wireless testing purposes I needed to change my built in hardware address or MAC (media access control) address in my Windows 7 distribution.
I will not go into what is the MAC address (you should be familiar with this term if you are reading something like this), I presume your first thought about this is: “He has to change his MAC address because he is doing something baaad:) Well, there could be a number of legitimate reasons why would you change your built in hardware address. Maybe your computer died which was connected directly to the ISP and that address was needed to authenticate or identify you or maybe you are worried about your privacy. If you were connected to the internet in a public web cafe, then you could be easily targeted by a hacker.
It’s pretty simple to change the MAC address in Linux, but in Windows (especially Win7) it’s a little tricky. You could change it in the registry, use different applications to change it, use different drivers and so on…
After looking around, I have found an application that worked for my Intel 5100 AGN wireless adapter in combination with the MS Win7. App is called Etherchange and you can find it on ntsecurity.nu website or HERE!
After downloading the app, put it in the root partition of your Win7 distribution (in my case it’s the C drive).
First thing you should do is see which is your current MAC address of the wifi card. In command promp (Win Run+type cmd and enter) type: ipconfig /all and find your mac. My ends in 10, and the plan is that it ends in 11 after the transformation:)
Then type etherchange.exe and press enter. From here you will be guided to change the MAC address.
As said, after entering the new address disable and re-enable the network adapter for the change to take place. Then again type ipconfig /all to see if you network adapter has the new MAC address.
You can use this app for any network adapter, but my mission here was the wifi adapter:)
Hope it helped!
