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 Xnity, download the Xnity app from the App store or from
Google Play™. If you already have the Xnity app, make sure you have
updated to 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.

Install using the modem router web interface
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 to the modem router and plug the
power adapter into an electrical outlet.
4. Wait for the Online LED to light solid green for at least one minute.
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 green, verify that the cable outlet is
working, or call your ISP to make sure you have a connection.

not connect to a WiFi network).
