As of September 1, 2010, Suddenlink will only support new-customer modems that are DOCSIS 3.0 or higher. This decision will enhance the Internet experience for all of our customers because older modems can affect download and upload speeds. If you wish to continue using your own modem, you will need to purchase one that is DOCSIS 3.0 or higher. You can purchase DOCSIS 3.0 or higher modems either from Suddenlink or from a store that sells such modems. If you prefer, you can also lease a modem from Suddenlink.


Note: New internet customers who subscribe to 15Mb or higher speeds and existing customers who subscribe to anything higher than 15Mb speed must have a DOCSIS 3.0 modem.  This means existing 15Mb customers can keep the DOCSIS 2.0 modem they have in place.

 

If you are purchasing a modem from a retailer other than Suddenlink, please make sure the modem you are purchasing is on this list of compliant modems:

 

The following modems are ones that are installed if leased or bought from Suddenlink.  While many modems will work and are listed below, these are the preferred modems.
