This modem can utilize up to 8 channels of downstream for a theoretical max speed of 343 Mbps whereas the Motorola SB6121 and other earlier/cheaper DOCSIS 3 modems can only utilize 4 channels maxing your download speeds out at 172 Mbps. Just something to think about if you plan on using this modem for a few years as speeds offered will inevitably increase.
Also, it *does* support IPv6 even though Comcast's page doesn't list it as certified yet. Motorola's data sheet specifically lists the SB6141 as IPv6 ready and tests with an Apple AirPort Extreme (v7.6.4) and MacBook Pro running 10.9 confirm this.
Update 2/4/13: Still working great without issue.
Update 3/25/13: Still not even a single reboot required.
Update 8/28/13: Still working great...
Update 7/8/14: First issue... had an outage for 15 min. Reset the modem and it didn't resolve the issue. Called Comcast, they reset something on their end and I was up and running again. First issue since I bought it.
Update 4/5/2015: Comcast recently upgraded my speed tier and I'm consistently getting speeds up to 180/25 Mbps.
The modem (as are all modems) was extremely easy to install. Plug in, call ISP and you are good. The speeds are fantastically fast and this modem was well worth the price.
****I purchased this white SB6141 over the black SB6141 for one main reason. If you do your research you will notice that the Black SB6141 are only issued to ISP's from Motorola. Meaning, if you purchase a black model from Amazon (or any store), you are purchasing a used or refurbished product (they also ship in ordinary brown cardboard boxes). The only consumer model of the SB6141 is the white model which ships in traditional packaging. The white model is THE ONLY model that comes with a warranty from Motorola. I know this because I called Motorola twice and spoke to two (2) different reps who said the same thing; "Black boxes are for ISP's and do not have a warranty while the white boxes are for consumers and come with a warranty". Further complicating matters is that the black SB6141's usually have old firmware on them because they were generally made a few years ago. White SB6141 have newer or the newest firmware because they are shipping directly from the manufacturer. Your ISP may or may not flash customer owned modems to the newest firmware. If you purchase the Black model, you might be purchasing a 3 year old modem with no chance of upgrading it (also remember that you cannot flash your own modem's firmware).
Do yourself a favor and research this white consumer model over the black ISP model before you pull the trigger.Read more ›
Lots of research and this one just kept coming up on top for me; reliable manufacturer, good reviews by others, ease of setup, built for the future with 8-up 4-down bonding. Works just like promised with never a hitch. My only complaint is, as others have mentioned, the lights are irritatingly bright; this I solved by mounting under my desk where it is out of sight.
TIP 1: Make sure you purchase this "Retail Packaging - White". Don't try to save the few bucks buying the black version; all my research shows they are refurbished rentals from ISP providers and the common complaint is that they stop working about the time the warranty expires.
TIP 2: Make sure your ISP supports the firmware. My cable company does not specifically show this model but it supports the same model two generations back - close enough. All I did was a Google search " modems supported by mediacom des moines" (my ISP, my city). Take the time to do your research. I did and I'm VERY happy (except for the irritating lights).
TIP 3: One mis-notion: Just because this modem is "state-of-the-art" for home use, don't expect speed increases just by swapping modems. (Though my wife and I swear our pages load faster even though speed tests show the same up/down rates as before.) You have to up your internet package (dollars) to do this.
One month update - as pleased today as the day I set it up. Never a bump or a glitch.
Eight months and I'm as happy as the day I set it up!
A year and a half - I'm still as happy as the day I set it up!
