Help

Hello. I need help activating my customer-owned modem.

I have a Hitron CODA57 DOCSIS 3.1 modem.

The Xfinity app activation fails and keeps looping to the Welcome screen.

Please remove my old modem, manually provision this modem using the CM MAC address, and push a fresh provisioning signal.

App activation does not work for this modem. Thank you.

Good morning @user_gwczvd our team would be happy to assist in activating your modem. 

Please send us a DM with your full name and address to Xfinity Support.

To send a direct message:

Click "Sign In" if necessary

Click the "Direct Message" icon or  https://forums.xfinity.com/direct-messaging

Click the "New message" (pencil and paper) icon

The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there.

As you are typing a drop-down list appears. Select "Xfinity Support" from that list.

An "Xfinity Support" graphic replaces the "To:" line.

Type your message in the text area near the bottom of the window

Press Enter to send it
