How Do I Set Up Charter Internet?

You’ve obtained your Charter cable modem, and now it’s time to get it all hooked up so that you can get online. Setting up your Charter modem involves connecting its included cables and then authorizing your service through the Web browser on your computer. If you also picked up a Charter Wi-Fi router, it's easiest to set that up now as well.

Step

Connect the provided coaxial cable between the cable outlet in your home and the coaxial input on the back of the Charter modem.

Step

Connect the modem’s power cord to an available electrical outlet.

Step

Connect an Ethernet cable from the "Ethernet" or "WAN" port on the back of the Charter modem to an Ethernet port on your computer. Most Charter modems come with an Ethernet cable.

Step

If you also have a Charter Wi-Fi router to pair with the modem, connect the Ethernet cable to the yellow “Internet” port on the wireless router instead of the Ethernet port on your computer. When this cable is connected, plug in the router’s power cable and wait for the power light to turn green and for the Wi-Fi indicator lights to light up.

Step

Open a new Web browser window on your computer. If Charter’s Identify Your Account page does not appear automatically, visit the Identify Your Account page manually (link in Resources).

Step

Select “Install New Service” under the I Am Here To heading and then enter your primary account phone number, account number and ZIP code in the provided fields. Press “Next” when you are finished.
