Also, some modems that have been purchased from a second hand vendor (online auctions, garage sales, pawn shops) may not work on the Cox High Speed Internet service.

Cox offers Gateway devices (combining a modem and wireless router in one convenient device) for rent or purchase. These devices are recommended for all packages of Cox High Speed Internet service.

 
Additional Cox Recommended Devices

The DOCSIS 3.0 devices listed below meet our service and performance requirements.
 

Note: DOCSIS 3.0 devices are required for all new Preferred, Premier, Premier Plus (where available), and Ultimate tier customers. Current Cox customers on those tiers should ensure they have a DOCSIS 3.0 device in order to consistently receive optimal speeds.
 

 
Legacy DOCSIS 2.0 devices (no longer recommended)

Cox recommends all customers use a DOCSIS 3.0 device from the list above.

There are a limited number of DOCSIS 2.0 devices that will continue to work on the Cox network, but if you are on Preferred, Premier, Premier Plus (where available) or the Ultimate tier, Cox strongly recommends that you upgrade to a DOCSIS 3.0 device for the best consistent speed experience. Future speed increases may not be achievable with these devices.
