Install using the modem router web interface

Before you begin:

  • Collect your cable Internet service provider (ISP) account information, such as your account mobile phone number, user name, password, and account number, and the modem router’s MAC address (on the modem router label).
  • If you use Xfinity, download the Xfinity app from the App Store or from Google Play™. If you already have the Xfinity app,  make sure you have the latest version.

Connect your modem router

  1. Turn off and disconnect existing modems and routers. If you are replacing a modem that is currently connected in your  home, unplug the modem and plug the new modem router into the same outlet.
  2. Connect a coaxial cable. Use a coaxial cable to connect the coaxial cable connector on the modem router to the cable wall  outlet. Make sure 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. Connect the power adapter.Connect the power adapter to the modem router and plug the power adapter into an electrical outlet.
  4. Wait for the Online LED to light solid white for at least one minute.Note: This process might take up to 10 minutes and the modem router might reset several times.Note: When the Online LED lights, your modem router is still not connected to the Internet. You must activate your modem router with your ISP.If after 10 minutes the LED is still not solid white, verify that the cable outlet is working or call your ISP to make sure you have a connection.
