Authorized Devices on the Spectrum Network/ Customer Owned Equipment

About Authorized Modems

Updated 9/03/2019


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.


Modems listed here can be used on the Spectrum network. However, only Spectrum-provided equipment is supported by our technicians. View the current list of Spectrum-provided equipment.

Minimally Qualified Modems

You may also choose to buy a modem that has passed minimal testing to confirm that it won't cause harm to our network. Though permitted for use on our network, we recommend against using Minimally Qualified Modems because they haven't been tested to confirm their ability to deliver your purchased internet service speed.

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

Below are the Minimally Qualified Modems that have passed the limited no-harms certification testing.

Note: Some modems that were issued years ago have become outdated. If you have a modem that was issued by us and hasn’t been swapped in the last six years, it might need to be replaced. 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.
