Good evening. i recently installed a XER10 to my fiber internet. I am receiving internet but in my app it show that i am offline. I have been on the phone with service and they still show the CM MAC of the old modem on my account, and when they try to add the Device MAC from the XER10 they are getting an error.

Chutzell76 Thanks for reaching out to us here for help with the new modem concern. I would be happy to help in any way I can. 

Can you send us a direct message with your full name, name of account holder (if different), and service address please?

To send a "Direct Message" to Xfinity Support:

Click "Sign In" If necessary

Click the "Direct Messaging" icon (speech bubble)

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
