In our college , the students have to register with their laptop's MAC address with the administrator to use the wi-fi access to the system. otherwise, Even though is signal is available, we cant use the wi-fi services. Can you computer experts, provide me a way to use the wi-fi without registering the MAC address ..

Why? They do this for good reasons. What is your good reason for wanting to violate their policies? – EBGreen Nov 6 '12 at 18:14
Because possibly they are blocking all google services like google books, maps, youtube,etc. And there may be a chance of hacking my laptop using MAC address – AGNI Nov 6 '12 at 18:19
If they are blocking something on their network, that is certainly their right. Again, they would be doing it for good reason. – EBGreen Nov 6 '12 at 18:20
The administrator is just finished schooling – AGNI Nov 6 '12 at 18:22

There's no easy way to do that due to the network architecture. Also, you probably shouldn't try to bypass network policy set by admins, as this is against the law in many countries and also against the terms of service of SuperUser.

MAC address is operating at Layer 2 of the network stack (data link) which is very low level and not really possible to bypass. If it were possible to bypass these restrictions then the security model of layer 2 would be broken. That's why it's not possible, short of some unforeseen vulnerability.

It's definitely possible, I went to a school with a similar policy and toyed to find them. However, I am obviously not going to list ways here due to the TOS and the fact that it is not documented information anyway (I was working with my school to fix those holes). – nerdwaller Nov 6 '12 at 18:39
Right, it may be possible, but anything that makes it possible is essentially breaking the security model of Layer 2 of the OSI model, which constitutes cracking / malicious hacking and is against the ToS. – allquixotic Nov 6 '12 at 18:43
@nerdwaller I wouldn't say it's so much a ToS issue as it is a bad idea issue. Obviously you could spoof a known good MAC address, but then you're going to cause a conflict on the network that will get you caught really fast, not to mention potentially break something very important to the college's IT department depending on the MAC address you clone. ToS or not, what you'd have to do to circumvent this security isn't something you want to just take a stab at and hope for the best. – Tanner Faulkner Nov 6 '12 at 18:45
