DOCSIS 3.0 Cable Modems

Cable Modem Buying Tips and FAQ's

All Charter Spectrum Internet Service subscribers, buy any of these DOCSIS 3.0 modems. If you subscribe to service over 60 Mbs, choose a modem with 8-channel download bonding to maximize your speed. They are the ARRIS/Motorola SBG6580, SB6141, SB6183 and SB6190. If you have telephone service with Charter too, you'll need a telephony or EMTA modem. The only readily available DOCSIS 3.0 model is the ARRIS TM822G. Here's a link to it at Amazon: ARRIS TM822G at Amazon.

All of these modems are high quality and have pretty much the same features, except of course 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. Buy one now and start saving those rental fees!

If I understand this correctly. If you buy one that is not supported by Charter, it won't work. You need to buy one that is supported by Charter.
