As a lot of people will report, time warner is now charging a cable modem fee for all new customers or customers who change plans (like I have). Its only $2.50/month in my case ($4 in nyc I hear) but its enough that it made me start researching cable modems. I'm posting this here because i've read in multiple places that getting a DOCSIS 3.0 modems can (not necessarily will, but can) decrease latency and also allow you to exceed network speed limitations set by your cable company (in my case time warner cable) versus the standard cable company's free/leased DOCSIS 2.0 modems. My plan with time warner is Turbo which here in Austin, TX is 20Mbit / 2Mbit with a Cisco e3000 running DD-WRT. I've never had any serious issues with my current DOCSIS 2.0 modem, a Cisco DCP2100, and (knock on wood) TWC has been a great ISP for me over the years. Network latency seems fine (22ms or so to google) and when I go to work where my internet connection is 300Mbit / 300Mbit+ (in a datacenter) the latency is slightly less than at home but I don't feel a difference when playing TF2, for example. So my questions are: 1) Is it really possible to exceed time warner limits with a docsis 3.0 modem? See here: http://www.amazon.com/review/R29HRUMIR7OMVI http://www.dslreports.com/forum/r23953208-Docsis-3-modem-for-lower-tier-useful 2) Will DOCSIS 3.0 modem reduce latency on my turbo level service? 3) My cable modem choices are pretty limited to only an approved list from time warner as follows: Motorola SB6121 $80 @ newegg (4 channel bonding, DOCSIS 3.0) Motorola SB5101U $20 used on ebay/cl or $55 new (DOCSIS 2.0) Cisco SPC2100 for $2.50/month (DOCSIS 2.0) Which modem would you pick?
