I wanted a second cable modem in the house to run off of our Charter ISP. Basically, long story short is that my parents say I use the internet too much at night blah blah blah so they disconnect it at night. So I just bought a Motorola Surfboard cable modem and I want to clone the MAC address from my downstairs cable modem so that when my parents pull the plug on the downstairs modem, I can just plug in mine upstairs and connect to the internet. (I have a cable plug and whatnot upstairs to connect to my modem so that is not an issue) Please help me!!!
