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 cable modem into the same outlet.
2. Use a coaxial cable to connect the cable port on the cable modem to a cable
wall outlet.
Make sure that the cable is tightly connected. We recommend that you
connect your cable modem directly to a 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 cable modem 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.

into an electrical outlet.

provider.
