Cable Modem Buying Tips and FAQ's

All Cox Internet Service subscribers who are buying a modem, must purchase a DOCSIS 3.0 modem. Preferred 100 subscribers should pick a modem with at least 8 downstream channels to maximize speed. Ultimate subscribers should buy a modem with 16 downstream channels. Gigablast subscribers should buy a DOCSIS 3.1, which are shown below (from the selection "Show All Modems with Downstream Channels of", pick "32 or more" and look for modems with DOCSIS 3.1 in their titles.) Essential subscribers can buy any of these modems.

Cox business customers should buy either the ARRIS/Motorola SB8200 or the SB6183 which are listed here on the Cox Compatible Business Modem List.

Cox Telephone/Voice customers: Call Cox and have them provision your current modem for telephone only, no internet data. When you do that, Cox won't charge you for renting it. Then buy one of the modems below and hook it up for internet only. You'll now have 2 modems (1 for phone and 1 for internet) and Cox won't charge you for either.

All of these modems are high quality and have pretty much the same features, except for number of downstream channels and those with routers built in. So don't worry too much about deciding which one to buy. Price should be a main factor in your buying decision.

You can click on any column header to sort that column. Also, you can narrow down your search by typing in the search box. For example, if you want to see only modems with Wifi-AC routers, type "ac" in the search box. Clicking on any price takes you to the retailer.
