Cable Modem Buying Tips and FAQ's

Time Warner, Road Runner, Brighthouse or Insight customers who subscribe to Lite, Basic or Standard Internet Service (typically less than $60 a month), buy any of these DOCSIS 2.0 modems. If you think you'll be upgrading to faster internet service in the future, buy a DOCSIS 3.0 modem at the top.

I work for TWC, Tier 3 will put any verifiable docsis 2 (standard and below) or docsis 3 (turbo on up) modem on your acct as long as it's not a voice capable as well, the list is to keep people from calling in with a docsis 1 modem and expecting ultimate to work on it. Arris CM820A, DG860A, Ubee DDW3611, DDW365, DDM3515 are all in use by TWC and accepted as customer owned modems.

And yes, buy a Docsis 3 modem if you can afford it regardless of your current speed package, because when TWC flips the switch in your area to where 300/20 is the top tier, Lite and Basic will be the only speeds that can be put on docsis 2.
