When I return to school in September, I plan on using my linksys wireless internet instead of ethernet. The problem is, the university doesn't want anyone else leaching off of the wireless, so they prohibit the use of wireless routers. To police this, they send around some kind of "spike" that will check to see if your computers MAC address is different from your routers MAC address, and if it is, they shut your internet off. A kid I know did a work around and got his PC and his router's MAC addresses to match, and the spike won't notice it. Is there anyway to do this on a Mac, or is this just a Windows thing? Help would be very much appriciated. Thanks!!!
