xfi say it is not compatible with my android phone. Help I can not install the modem.

I am trying to install a new modem.   I went from 600Mbp to 400Mbs and they said I had to install a new modem.   But when I try to load the xfi app on my phone it says "it is not compatible with my device"   Is there another way to install the modem?

Try calling 1-855-652-3446. That is their self-install device activation line.


If that doesn't work for you, you can call 1-800-comcast and tell a rep that you would like to have a new modem activated / provisioned for service. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.
