My friend has the misfortune of his MAC adress (the computer's not the WLAN card's) regestered in his parent's computer (hooked up to the router), so his Mom allows only 2 hours of internet time a day! Can he somehow change his MAC adress or mask it, so he can still use the valuble resourse that is the internet for more than 2 hours? Or is there a simpler way that doesn't require changing any hardware or buying anything?
