I.P.: I noticed that the Motorola SB6120 is one of the modems recommended by Time Warner. In light of the talk at the above mentioned link about IPv6, what is your recommendation?
Here is the link for Time Warner

Well, you'll note that TWC also appears to have the SB5101/SB5101U on the list (which does support IPv6), and only mandates the purchase of a DOCSIS 3.0 modem for certain speed tiers (though it appears they are specifically supporting the $125 SB6141,
not the $80 SB6120 on the link provided). This to me speaks of confidence on their part of the recommended DOCSIS 2.0 modems being able to handle the IPv6 transition without support issues. Given what I say about speed requirements and them apparently drawing a line on DOCSIS requirements between the Standard and Turbo packages (which are 7-10Mbps with 15Mbps burst and 10-20Mbps with 25Mbps burst respectively), I would say you could safely get away with saving $30 (or more) over the SB6120/SB6141 and buying a DOCSIS 2.0 Motorola modem from the list, but that's just
my thinking. If you can make the argument in your own budget and usage patterns to
ever potentially support paying the price for the Turbo through Ultimate service tiers even in you can't currently or just want to play it safe with future compatibility, then perhaps spend the extra bit on a DOCSIS 3.0 modem... otherwise don't buy what you don't need.
I'd also like to point out that modems and routers are two separate items best not confused as it appears there might be a little confusion with a couple people.
Modems hook up to the bare wire bringing the service into your home.
Routers split the resultant ethernet connection out of the modem to multiple devices through either more ethernet cables or wireless networking.
And a gentile reminder for those who might have missed it in the thread and posts, you
might be able to save some cash going through
Earthlink instead of TWC directly if your area's set to support it.
