Before you change anything, you need to know the internal name of your wireless card, and its current MAC address. The good news, however, is that you can achieve the same thing with a bit of extra effort by using inbuilt terminal commands. Now you can reconnect to that wireless network, all set for another quick burst of internet access. Your network connection will restart, and a box will pop up to tell you the MAC address has been changed. This used to be quite a complicated process, but not anymore.
