About Authorized Devices

Spectrum Internet customers are required to use an authorized modem to connect to the Spectrum network.

For a monthly fee, Spectrum will provide a pre-configured WiFi router. Customers may also choose to use or purchase their own router. Learn more about In-home WiFi and routers.

Note: The information in this article applies to Spectrum Internet customers only. Spectrum Business Internet customers are required to use authorized Spectrum-issued modems. Learn more.

As a Spectrum Internet customer subscribing to a New Pricing and Packaging service tier, you're offered a compliant modem at no additional charge that has passed our full certification testing for optimal performance. In the event that we upgrade network speeds and your modem doesn't support the new speed tier, we'll notify you and give you the option to upgrade your modem.

Note: DOCSIS 1.0/1.X modems are no longer supported on our network. To get a replacement modem, contact us or visit a Spectrum store. Please recycle your old modem or bring it to a Spectrum store for proper disposal. If you do a modem swap with us, you'll receive a mail return label in your package which can be used to return your old modem.
