Suddenlink Approved Modems

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).
