Re: [Connectivity] MAC Address Scam? My real question here is how is a gateway from motorola that is doc 3 get blacklisted? So blacklisted seems like it may be a bad term. It is possible, this was someones personal modem they sold, and in doing so never removed from an account they had with comcast. It is also possible that account went over bandwidth limits repeatedly and got some sort of banning. But this should all be clearable at a local office with ID if that's the case. Save for one issue. This creates a conflict in the equitpment system as the same modem cannot be on 2 accounts even if one is terminated. If that is the CASE, have the seller get the modem removed from his comcast account he should just have to call in to do it [I agree its BS, I fight this every day on installs and it pisses me off to no end how stupid it is, but its the way it is and no matter how much we have bitched no one has ever taken the initiative to fix it, generally I am dealing with one person who moved across state lines taking their modem with them but it never works out as easily as it should.]. If you are paying for service, and are live, hook the modem up, you should get a provisioning page once it locks in and firmware updates are done. Enter your account number, and phone number associated with the account [they can even give you this over the phone if you do not have it on a bill]and go through the provisioning setup, worst that can happen is nothing. Best is you get the bug I see ever so often and get the modem provisioned and working and they keep a place holder on your account instead of the modem mac. Good luck.
PS the paper work has nothing to do with what the children claiming to hack modems were saying you do not need it technically to provision a modem it is related to what the government would do when they found out you did it as its against laws. but.. That's a moot point right now.
I am making a couple of assumptions 1 is this modem is brand new to you, and you have not had it online for a few months and been blacklisted for excessive bandwidth usage. 2 is the modem is not stolen from someone who has Comcast working with them to recover them. 3 is that the MAC banning will be done through the local cmts only and not on a regional or national level. try to provision it with the walled garden site and see.
