Connect your modem router
1. Attach the antennas on the threaded
antenna posts of the modem router.
2. 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.
3. Connect a coaxial cable.
Install using the modem router web interface
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.
4. Connect the power adapter to the modem router and plug the power
adapter into an electrical outlet.
The startup procedure takes about one minute. When it is complete, the
Power LED lights solid green. If the Power LED does not light, make sure that
the Power On/Off switch on the back panel is in the On position.
5. Wait for the Online LED to light solid green.
This process might take up to 10 minutes. When the cable modem comes
online, the Online LED stops blinking and lights solid green for at least a
minute.
