DOCSIS 3.0 Cable Modems

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-channel bonding downstream to maximize speed. These are the ARRIS/Motorola SB6141, SB6183, SBG6580, SBG6700, SBG6900, Netgear C3000, CG3000Dv2, C6300 and C3700. Ultimate subscribers should buy a modem with 16-channel bonding downstream. These are the ARRIS/Motorola SB6183, SB6190, SBG6900 or Netgear C6300.

Cox business customers should buy either the ARRIS/Motorola SB6141 or the SB6183 which are listed here on the Cox Compatible Business Modem List.

All of these modems are high quality and have pretty much the same features, except for number of download 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.

There are a few that Cox says will work, but as of today, they are hard to find.

Instead 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 any of the above modems 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.
