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.

Connect a coaxial cable. Use a coaxial cable to connect the cable port on the modem router to a cable wall outlet. Make sure that the cable is tightly connected. We recommend that you connect your cable modem directly to a USB Reset Cable cable wall outlet. If you must share the connection, use a 3.5dB (1 to 2) splitter.

After 10 minutes, if the Online LED doesn’t light solid, make sure that the cable outlet is working, or call your Internet service provider (ISP) to make sure you have service.
Note: When the Online LED lights solid, your modem router is not connected to the Internet yet. You must connect a router or computer to your cable modem, and then activate your cable modem with your cable Internet provider. -
