So yes, you can reuse the cable modem, as long as the Cable ISP supports it.
Thanks. I remember some people said not to buy used cable modems from eBay and stuff for being blacklisted.
Those are most likely modems that didn't get returned. People move, cancel their cable, "forget" to return equipment, end up in some other state they can't be tracked down by the creditors, and end up selling the cable modem on eBay.
If the provider is DIFFERENT, you may be able to get away with such a modem, as e.g. Comcast does not know what modems TWC used, etc.... if the provider is the SAME, the modem hardware address will come up as stolen, and you will have a problem.
