How to self-install Spectrum internet

Before you begin, make sure you received the installation equipment you’ll need from Spectrum:

  • Modem
  • Two coaxial cables
  • Ethernet cable
  • Coaxial cable splitter
  • Instructions

Spectrum should provide you with a perfectly good modem, but if you think you need something fancier for work, gaming, or just general use, then check out our line up of the best Spectrum modems.

Once you have this equipment handy, follow these three simple steps to self-install your Spectrum internet.

1. Connect your modem

Choose the coaxial cable that’s the best length for reaching your modem location. Connect one end of the cable to the cable outlet and the other to your Spectrum modem. Plug the modem into the power outlet using the provided cord. Wait for the online status light on the modem to turn a solid blue.

If you’ve signed up for a Spectrum TV/Internet bundle, then you’ll need to use the coaxial cable splitter to connect to both the modem and cable box.

2. Set up Ethernet cable

Connect one end of the provided Ethernet cable to the modem and the other end to your computer or other device. If you’re setting up a Wi-Fi network with a Spectrum router, then connect the ethernet cable to the router instead.

3. Activate your Spectrum modem

Go to on your smartphone (or other internet-enabled device). Click on Get Started. You’ll need to sign in to your Spectrum account. Just follow the instructions on this site to activate your service.

Once you’ve activated your Spectrum internet service, you can create a username and password to manage your equipment and service.

1. Connect your Spectrum cable box

Screw one end of the provided coaxial cable to the outlet on your wall. Connect the other side to your Spectrum cable box (also called a receiver). Plug in the cable box using the power cord. If you’ve signed up for a Spectrum internet/TV bundle, then you may need to use the coaxial cable splitter to connect both your modem and receiver to the wall.

2. Turn on the Spectrum cable box

Press the power button on your Spectrum remote to turn on the receiver or cable box.
