* Actual speeds will vary, and are often less than the maximum possible. Data transmission speed is approximate and depends on the configuration and capacity of your network, as well as the amount of traffic on the network.
** Actual data throughput will be less due to physical layer overhead (error correction coding, burst preamble, and guard interval). Certain features may not be activated by your service provider, and/or their network settings may limit the feature’s functionality. Additionally, certain features may require a subscription. Contact your service provider for details. All features, functionality, and other product specifications are subject to change without notice or obligation. DOCSIS 3.0 modem capabilities are dependant on the services available through the CMTS. Please verify with your CMTS vendor their specific DOCSIS 3.0 implementation roadmap.

“Motorola SURFboard SB6141 DOCSIS 3.0 Cable Modem: Overview & Unboxing by TechHarvest”

“Easy install, fast speeds, and no issues so far! :
Swapped out my Comcast rental modem, was up and running in just a few minutes, and now I don’t have to pay the $7 modem rental fee to Comcast. I’m provisioned for the 105/20 Mbps package and typically get 120/20.5 Mbps.

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. — J. Cameron”

“1 1/2 – year, still very happy! :
Tired of paying my ISP to rent one of their modems.

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! — Les L.”

“have comcast? use the auto-activation. don’t call those morons. :
hey, amazonians! i got this because i read the other reviews that it works with comcast. unfortunately, comcast doesn’t know that it works with comcast – are you surprised? i called and was on the phone for more than an hour while the tech tried to enter in all the information over the phone. they said i needed to bring it into a comcast location to get it manually entered – shut the front door. i asked for a supervisor who also knew nothing. i heard munching on popcorn in the background. whatevs.

i disconnected my old modem and plugged this one in. i waited until i saw all the pretty lights and then went back to my computer and tried to open a website. the browser automatically directs you to the comcast activation page. log in and follow all the simple instructions. the page will auto-detect your modem and then activate it. you just press the easy button and wait a few minutes. you never have to talk to a meatbag attached to a phone line. set it and forget it. in a few minutes it’s done and you’re connected.

sorry i had to learn this the difficult way. hopefully this process will be easy for you.
nice shiny modem with flashy lights. nice internet connection.

sb6141 – 5 stars for ease of use and sweet lights.
comcast – 0 starts because you always get 0 stars. — J. Do”
