My broadband co. has started charging $5/mo. to rent my cable modem. THey provide the option to buy your own, which I'm thinking of doing. But, they want $50 to come install my modem. Come on. I can screw the coax into a new modem and plug the ethernet into the new modem. Do cable cos. (mine is RCN/Starpower) specify a given MAC address for the cable modem for each address, so they need to check the new one and put it into the system? If so, any workarounds? Should I just berate them so that they let me call in the MAC address?
