Option 1: install using the Nighthawk app

1. Make sure that your mobile device is using an LTE Internet connection (do not connect to a WiFi network).
2. Open the Nighthawk app.
3. Follow the steps in the app to connect your modem router.
4. You must activate your modem router with Xfinity. See Set up and activate your modem router.

Option 2: install using the modem router web interface

1. Turn off and disconnect existing modems and routers.
   If you are replacing a modem that is currently connected to your home, unplug the modem and plug the new modem router into the same outlet.

2. Use a coaxial cable to connect the cable port on the modem router to a cable wall outlet.
   Make sure that the cable is tightly connected.
   We recommend connecting directly to the cable wall outlet.
   If you must share the connection, use a 3.5dB (1 to 2) splitter.

3. If you have Xfinity Voice, connect your phone to the Tel 1 port on the modem router with the phone cable.
   If you subscribed to two phone lines, connect the other phone to the Tel 2 port.
   Note: The Tel 2 port only works for a two-phone line subscription.

4. Connect the power cord to the modem router and plug the power cord into a power outlet.
   The modem router might reset multiple times when it is powered on.
   

5. Wait for the Online LED to light solid white.
   This process might take up to 10 minutes.
   Note: If after 10 minutes, the LED is still not solid white, verify that the cable outlet is working, or contact Xfinity to make sure you have a connection.

6. You must activate your modem router with Xfinity. See Set up and activate your modem router.
