Suddenlink Approved Modems – ApprovedModemList.com

Several devices appear on the Suddenlink approved modems list. You will find the best approved modems based on WiFi, DOCSIS 3.1, and value below. Suddenlink no longer maintains a official approved modems list. Suddenlink states as long as you use a DOCSIS 3.0 or DOCSIS 3.1 modem (no voice modems), it should work with their network.

As of February 5, 2021, Suddenlink now supports DOCSIS 3.1 modems. You may be in a region that currently does not offer DOCSIS 3.1 service. You may still use a DOCSIS 3.1 modem; it will operate in DOCSIS 3.0 mode until DOCSIS 3.1 is supported locally.

Suddenlink does not support voice modems. If you require telephone service, you must use a Suddenlink eMTA (cable modem and telephone adapter). You can still use your own cable modem for internet service.

Read the Cable Modem Buying Guide to help you choose a modem. Do not forget to purchase your modem accessories.

Internet providers have begun removing some DOCSIS 3.0 modems from their networks. To maximize the years of use from a modem, it is strongly recommended to purchase a DOCSIS 3.1 device (the latest standard).
