A:Answer Google Home should work even if you're using your Xfinity modem/router combo. We recommend contacting our support team to check on your Google Home to know why it's not working. You can reach out to us here: https://support.google.com/googlenest/gethelp
Also, if you purchase Nest Wifi, since your modem from Xfinity is a modem/router combo, we recommend disabling the Wi-Fi functionality of the combo or putting it in Bridge mode to avoid Double NAT as it may cause connectivity issues. And, the Nest Wifi points have a speaker with the Google Assistant, so you can play music, manage your Wi-Fi network, find answers, control your connected devices, and more using just your voice.
