A:Answer Nest Wifi works with most modems and internet service providers, including Xfinity. You can connect Nest Wifi directly to your modem with the Ethernet cable to set it up and broadcast your Wi-Fi network. If your modem 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.
