So long story short 1.) I live on campus at a University 2.) The University will shut down your ethernet restricting you to wifi (1mb/s compared to the 80mb/s ethernet) if you use it too much 3.) To use ethernet you must register your computers MAC address, like anything else say a 360 that uses the wire 4.) I always get shut down because I Skype and play games online How can I change my MAC address // navigate around the schools blocks? My roommates computer still works fine on ethernet and the only way I can think that they identify me is MAC address. What can I do?
