Before you begin:
• Collect this cable Internet service provider (ISP) account information: your
account mobile phone number, user name, password, and account number.
• Collect this modem router information: the model number, which is C7500,
and the MAC address and serial number from 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.
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.
Install the modem router
4. Wait for the Online LED to light solid white for at least one minute.
This process might take up to ten 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 ten 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.

1. If your current modem is leased from Xnity, call Xnity support to remove
