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 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.

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.

a. Make sure that your mobile device is using an LTE Internet connection (do
not connect to a WiFi network).

The activation process takes about 5 minutes.

e. Go to Step 5.
2. If you use another Internet service provider:
a. Connect your computer or mobile device to the modem router with WiFi
or Ethernet:
WiFi: Use the WiFi network name (SSID) and password on the modem
router label to connect.
Ethernet: Use an Ethernet cable to connect a computer to an Ethernet
port on the modem router. (Your computer must have an Ethernet port.)
b. Launch a web browser and enter routerlogin.net or 192.168.1.1 in the
address eld.

this information.
