On my schools WI-FI network I want to make one laptop look like another, as I want to use my Thinkpad instead of the issued Dells. I know I need to clone the MAC address of the issued one so the Thinkpad looks like the other. How do I go about doing that and what else would I need to do to make sure that its not easily seen on the network? (I'm not adding it to the domain, I just want internet access) Thanks
