Getting a Self-Install Kit

To have a Spectrum Internet and WiFi Self-Install Kit shipped directly to you, contact us. The kit will generally arrive within three days.


Spectrum Internet and In-home WiFi service and equipment must be available in your area. You'll also need the following:
  1. A computer capable of connecting to the internet
  2. A current subscription to at least Expanded Basic TV service
    Note: Basic TV service does not qualify for self-installation of Spectrum Internet Services.
  3. An active cable outlet within 6 feet of the modem
Note: Please make sure you understand and agree with the self-installation terms and conditions. If you fail to self-install for any other reason other than Spectrum-issued equipment failure, you'll require a professional installation that will result in a service charge.

Installation Instructions

Follow the steps below to install Spectrum Internet and In-home WiFi. Or use the instructions included in your self-install kit.

Download the installation guide for your modem and router in English or in Spanish.

  1. Connect one end of the long coax cable to the outlet in the wall and the other end to the modem.
  2. Connect the power cord to the modem and plug in the modem. Wait approximately two minutes until your modem turns on.
  3. Attach the stand to the router.
  4. Connect one end of the Ethernet cable to your modem and the other end to the yellow internet port on your router.



  1. Connect the power cord to the router, then plug it into an outlet. The router is ready to use when the power light changes from amber to green. At that time, the lights for 2.4 GHz and 5 GHz indicate which WiFi bands are available. If none of the lights turn on, make sure the Power On/Off button is in the ON position (pushed in).
  2. Connect a wireless device to your router.
    1. Open the program or application that manages the WiFi connections on your device.
    2. Look for your unique Network Name (SSID) beginning with "MyCharterWiFi" or "MySpectrumWiFi." It's printed on your router and on the stickers provided. If you see the name ending in "5G," your device is 5 GHz-capable. Connecting to the "5G" network may provide a better experience.
    3. Enter your unique pre-set password, also found printed on your router and on the stickers provided.
    4. Follow steps a-c to connect other devices.
    5. You may also use another Ethernet cable (not provided) to establish a wired connection from the router (using ports 1-4) to a device such as a laptop or desktop computer.
  3. Open your browser to confirm that you're connected to the internet.

Activate the Modem

  1. Open an internet browser and go to the self-activation site and select Install New Service to activate the modem.
  2. Follow the prompts to complete activation.

Wireless Name/Password

Your router has a unique preset WiFi Network Name (SSID) and Network Key (Password). The default SSID and Network Key are uniquely generated for every device to maximize your wireless security. This information is printed on your router.

Note:We recommend that you don't change the preset WiFi Network Name and Network Key. If you change the settings, the information printed on the router will no longer apply.

Failed Self-Installation

You can request the services of a technician if you fail to complete a self-installation.

You'll incur a service charge at the professional installation rate if the technician determines the failure is directly related to:

  • Your equipment (TV, entertainment system, etc.)
  • Your inability or unwillingness to complete the self-installation process
  • Mistakes you made during the self-installation process

If the technician determines that the failure is directly related to Spectrum-issued equipment or our wiring infrastructure, no installation or service charges will be applied.

Note: If you attempt to install your own device from our authorized modems list that doesn't meet the speed tier you ordered, you'll get a message that notifies you of this and you'll be asked to acknowledge this before you proceed.
