By the way in the ordering I looked at the approved Comcast modems for my company/area etc and the Motorla SB6120 DOCSIS 3.0 is on the list/so I'm hoping it will work. And on that same page Comcast goes on to say that DOCSIS matters and that if one is subscribing to either Performance(that's me) i can use either 2.0 or 3.0, but if one goes faster meaning Blast,Ultra, or Extreme then for sure DOCSIS 3.0 is a must. So I interpret that to mean I could have gone with the Motorola SB5120 that seems to commonly get high reviews and no complaints. I'm having a few second thoughts haha. I coulda got the SB5120 for $20 less and supposedly its without the 2minute plus boot time that some folks complain they get with the SB6120-so we'll see.
