How To Fix Xfinity Phone Not Working After New Modem?

To resolve an issue with your Xfinity phone not working after a new modem installation, ensure the modem is properly installed and activated. Restart the modem and check all connections.

If the issue persists, contact Xfinity Support for troubleshooting or possible modem replacement.

In case you have just bought a new modem and installed it but now it is not working then you have to contact Customer Support and talk with them to resolve the issue.

What happens is that in many cases the new modem does not know that the phone is already activated as this information was stored in the old modem.

On the other hand, this information needs to be put inside the new model by a phone activation signal that has to be given by the phone activation representatives.

The Xfinity team is probably aware of this situation and is working to fix it however after you contact the Support Team of Xfinity it will probably be helpful if you talk to them regarding this when you contact them.

A few users have also said that replacing the 2 wire telephone cable from the modem to the wall jack with a 4 wired one has helped them in solving this issue so you can also try that out and see if that helps.
