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.
Coaxial

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.
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

This process might take up to ten minutes. When the cable modem comes
online, the Online LED stops blinking and lights solid green for at least a
minute.
