Your modem is assigned to another

Thanks as always @EG for bringing this to our attention, we were able to figure things out pretty quickly. =] Often times, especially with modems from other accounts, we have to contact our inventory team to move the modems information in the system. In this case, we were able to register the device super easy and help get @Customer777 up and online within 10-minutes.

Thanks again for taking the time to work with us! Have a great rest of your evening, and an even better start to your week.

Thread now being closed. For any new concerns, please create a thread in the appropriate forum.

Concern moved here to the Customer Service help section for greater exposure to actual Comcast employees for assistance.

EG, thanks for volunteering! 

Thanks for moving my thread to a more appropriate place, my issue is still unresolved.

Greetings, @Customer777! Thanks so much for taking a moment out of your busy day to leave a post on our community forum. I'm sorry to hear you're having issues with your modems, but you have definitely come to the right place for assistance.

Under usual circumstances, we tend to see this sort of message when a customer buys a used modem from a previous customer, or when a customer transfers their service to a new address or a new location. The other account being referenced may just be your own. Have you recently moved or had an address change, by any chance?

No, no move or address change. Just closed and opened a new account at the same address. Both these modems were actively being used on the one account, one from the beginning and the other till I closed the account yesterday, 11/27/21.

Xfinity Support fixed it!

Thank you!!
