Best Cable Modem You Can Buy
Posted by: BrianD1337 from: Jacksonville, FL on
If you want the best cable modem on the market with the fastest possible speed and reliability, this is the modem for you. Comcast is doubling the speed on all of their plans between March-May of 2013 and I bought this modem to take advantage of the faster speeds (DOCSIS 3.0 modems are required for speeds over 36-40Mbps).
This modem delivers as promised as I've already seen a huge increase in performance before the speed increase has even gone into effect!
Here's some technical information for those interested:
This modem not only supports DOCSIS 3.0 which is the latest standard for cable modems but also supports the highest number of simultaneous download (8) and upload (4) channels for DOCSIS 3.0 modems at this time (8x4 channel bonding). Not all DOCSIS 3.0 modems are created equal since older models only support 4x2 bonding (i.e. Motorola SB6121) !
This channel bonding feature is what enables DOCSIS 3.0 modems to attain much faster speeds than the DOCSIS 2.0/1.1 modems that only supported a single channel for download and a single channel for upload. Since a channel is capable of approx 40Mbps (36-38 in real world use), this modem is capable of downloading at speeds over 300Mbps and uploading at over 150Mbps while the old DOCSIS 2.0/1.1 modems are stuck in the 30s.
In addition to speed increases, the channel bonding will also make your modem more stable. If the modem encounters a failure to communicate on one channel, your modem won't drop offline like the old modems would since it has somewhere between 1-7 others as well (depending on your provider).
Even though Comcast's speed increase has not gone through yet, my modem connected on 8 downstream channels and 2 upstream channels and I immediately saw a 44% increase in download speed and a 25% increase in upload speed.
Your cable provider might not offer speeds over 40Mbps just yet, but with this modem you'll be prepared and your connection will likely be more stable if you're coming from a DOCSIS 2.0/1.1 modem.

I have Time Warner and this fixed my disconnects
Posted by: John44111 from: Cleveland Ohio on
I am the Network Operations and Data Center Manager for the City of Cleveland so.. My recommendation on this modem comes with a bit of weight. For some unknown reason about 2 months ago Time Warner cable was giving me disconnects on my leased (4 dollar a month) modem from Time Warner. I have had cable internet from them almost constantly since 1995. I have had probably 4 outages in that period of time. RECENTLY however I was getting disconnects every 30 minutes. I of course have network monitoring equipment and took a look at it. The numbers on my line were all good. I WAS getting good signal. For some reason the modem kept disconnecting. I checked out the cables. the splitter etc. All was fine. Anyhow. my leased modem was docsis 2. and the manufacture date was 2005. Anyhow.. on my old modem I noticed one downstream channel was made.. when it got interrupted the connection dropped. On my NEW Motorola SB6141 I see in the status page 4 downstream channels are created. When one fails the other three maintain the connection. So if you are "frugal" (cheap) like me you will resist buying a modem and just pay your 4 dollar charge. This modem I have had in for a week now. I have my connection monitoring software watching and in the past week it hasnt gone down once. so.. is 99 dollars worth it for flawless connection? I think it is.. so I bought one and am very happy. Also.. another tip. buy this modem.. dont buy the router modem combos.. if your router goes bad in a combo.. you got a dead modem. Keep the modem separate. Motorola makes good products too I have loved their surfboard products for many years. My old one died after 10 years.. I went with the leased nonsense they gave me.. but now I am back to Motorola.
oh and it did NOT make my connection any faster.. Some might be buying this thinking it will make your connection faster. I have noticed ZERO difference it just doesnt disconnect.. which is what I needed.

Great modem for Time Warner Cable users.
Posted by: sillycar from: Rock City Falls, NY on
I purchased this modem so that I could stop Time Warner Cable from charging me a monthly fee for their modem. I also purchased a Netgear Nighthawk wireless router to use with it because there is not a built in wireless router in this modem. Motorola does offer another model that has a wireless router built in, but it did not get great reviews and my family is starting to use more and more wireless devices lately, so I decided that a robust wireless router was in order. Also, this motorola modem gets fantastic reviews, while the model with the wireless router built in gets a fair amount of negative reviews. I'm not trying to discourage anyone from buying that model, I'm merely stating why I went with this model. This modem was a snap to set up and start using. I did have to call Time Warner cable and give them the MAC address of the modem so that they could set it up to work with their service, and I had heard that it could be a nightmare (half an hour to an hour on the phone people were telling me), but it only took about 15 minutes for them to get it all set for me. Combine that with the 15 minutes it took me to unpack and connect everything myself and it was up and running in about a half an hour. Once that was done, the modem has been working fantastically ever since. I have had zero issues since installing this modem. As for speed, speed tests (using Time Warners speed test and OOKLA speedtest) before and after installing the modem were about the same. I have Road Runner Turbo, and I think Time Warner has control over the speed, so I can't really say if this modem would be faster for someone who uses a different ISP than Time Warner. My speeds have never been an issue for me. I will say also that we are running more and more devices in my household, and I have not noticed any slowdown in our network using this modem. The one negative I listed in the "what's not so great" section at the beginning is one that I noticed another reviewer wrote and it was one of the only negative things that I saw anyone say, so I'm reiterating it in my review here. The lights on the modem are VERY bright (i've included a photo in the darkness to give an idea of how bright) and the bottom light does always keep blinking (I've read that this may not be the case with certain ISPs, but with mine it blinks constantly), so if you're going to use this modem in your bedroom, you may want to figure a way to put the modem in a cabinet or find some other way to block the bright lights, but for me, I have installed the modem in my basement over my tool bench and I think it's pretty cool to have the bright lights. So for me it's really not an issue, but I'm writing about it to be thorough. I think this modem is great and I have been using it for about a month and a half so far. Also, I entered that I use this in a small home.

Faster Than Other 3.0 Modems
Posted by: CLEMSON1881 from: Clemson, SC on
Using the exact same network (Apple Airport Extreme and Express) and ISP (Charter) I clocked around 60 to 75 MBPS with the previous generation Motorola 3.0 modem (6121). Now with this model I routinely clock around 120 MBPS. Uploads were increased as well. Went from 4 to 5 up to 18 to 22. These were incredible gains and all I did is upgrade the modem to this new model. Worth an upgrade.

Great overall modem
Posted by: mhljhjhl from: Orange County, CA on
I bought this to replace an old DOCSIS 2.0 modem I have. I settled on this after through searching and research. This is the top of the line modem on the market and the speeds prove it! Fast sustained speeds no hickups downloading YouTube videos like my previous modem, no waiting for things to load. The only flaw of this modem is the status LEDs, they are very bright, lighting up my office at night, which personally is not a big deal but could be if you keep your modem somewhere it could affect you, plus the connection light constantly flashes which is slightly annoying yet personally not a problem. If you are in the market for a cable modem look no further!!!!

The Maserati of Modems
Posted by: CactusDawg from: Tucson, AZ on
I have used several different modems on my high-speed internet connection and this beats them all. Don’t waste your time with any other modem!
The difference is quite apparent with Net Flix, YouTube and other video services. It handles several streams at once; you can use your computer while watching Net Flix with no slow down. Previously, Net Flix would give me a “loading” message and the movie would stop. No more!
The modem comes in white. That was the only color BB had several weeks ago. I found it funny as the technically challenged would now be able to tell the modem from the router. Tech support: “The modem is the WHITE box.”
My only gripe is that it stands vertically. I put mine horizontally with the wall mount cutouts on the bottom not to block the ventilation holes.

Great replacement for Motorola modem from TWC
Posted by: Bill from: on
This is a simple plug&play replacement for the similar Motorola model issued by Time Warner Cable. A while back they started charging $10/month to rent a modem....this was $70 to purchase and use for years without rental fees, and looks very similar and works the same. Works just as well. Doesn't have the multiple Ethernet jacks on the back, but, these days, you really only need one for your wireless router. The body is glaring hospital white, and, speaking pf glare, the operating blinking lights are very bright and distracting in a dark room. If you are with Time Warner Cable, you will need to make a free call to them to authorize this new modem, mine took about 20 minutes. As part of that set-up, you will need to make a WIRED connection to this modem from your computer, NOT using the wireless router in your house. Once the computer, modem, and the person on the phone are all connected, you can then hang-up and reconnect your wireless router to this new modem. It may take an hour or two for your wireless router to "learn" the language of this new modem but they will eventually "get along" just fine.

The cable modem to buy
Posted by: NetMan2 from: Vinings GA on
SB6141 is sold as a "new, improved" replacement for the venerable SB6120/SB6121
Comcast Atlanta fully supports the SB6141 now
Excellent DOCSIS 3.0 performance, solid up & down channel bonding
It's the one you want, particularly if you have a CATV system with MoCA data traffic (TiVo, etc)

Constant Timeouts and loss of connection till Zoom
Posted by: falconman515515 from: Fresno, CA. on
I had an issue about months ago with my Motorola SB6121 after some use ... all the sudden I would lose connection for a few minutes then it was back Over & Over & Over .... had them replace EVERYTHING in my house ... new wire from street to house from outside through the house into my office to my modem .... So I told them to just give me one of their junk modems and I was good to go for a while.
So I decided well I just had a bad one no biggie ... and now they have the brand new Motorola SB6141 that’s a bit future proof so I thought heck ya let me give that one a try since I don’t want to pay Comcast for their old one they gave me.
Bought the SB6141 and 2 days later ... Boom ... drops off for a few minutes then back up, then off for a few minutes then back up .. over and over ... and later in the night it would drop off completely for a while then come back. Weird thing the modem's lights stayed like normal and the signal lights looked like all was good but it wasn't.
So I decided to dig around and research on Comcast /Xfinity and Motorola SB6141 and 6121 modems and Low And Behold there is TONS AND TONS of issues just like mine All OVER the Internet!
And reading through a bunch of things I kept seeing this Zoom Modem being recommended and people saying my SB6141 sucked and lost connection constantly and after getting the Zoom Zero issues. So I found it locally here at BB for 70 bucks and thought before I bring more techs out I'll try it.
For Days and Days now late at night my internet was DONE ... dropping off, resetting, and losing connection all together.
Zoom 5341j has been connected all day and all night and 100% ZERO ISSUES ANYMORE!
I know it's only one night (I will be sure to come back and update) but I know Dang well that if my SB6141 was still connected my whole house would have been down again tonight.
This Zoom modem I guess works better with connections that are not perfect and may have noise and slight connection issues (not sure what you would call em' I read about what they are but don't remember) ..... Many who have no issues with the Motorola Surfboard line may have rock solid zero interruption or flawed signals .... Many do not and if you have any kind of connection issues or errors or constant reboots or restarts then BUY THIS MODEM!
So happy I decided to research and fix this issue myself by finding this new modem.
Great looking little no frills modem that just plain Works
And when I called to have this thing activated (which took about 5 mins after I got a rep ... very quick and easy) ... he made it a point to tell me that he likes these Zoom modems and knows How Well they work and how stable they are and he gets TONS of service calls for the Motorola stuff but hardly Ever Ever gets a service issue with a customer using one of these modems.
Looks like I Finally got a modem that works and works well with all kinds of connections and is Also like the SB6141 Future proof with the 8 Bonding down and IPV6 support!
If you are having issues with your cable internet connection where it loses connection many times a day for no reason then comes back like it's timing out and also loses connection all together then Buy This Modem (do some searching on SB6141 (or 6121) Timeouts (it's mostly something called a T3 Timeout seems like) ... you will see what I'm talking about ... you will save TONS of time troubleshooting with Comcast and I think overall just get a better overall cable modem.
Hope this reviewed has helped anyone who has the same issue as me ... feel free to comment and I will answer any questions you may have.
I will be back with update!

Faster and Better
Posted by: HKTL from: Denver, CO on
Simple and easy to use/install. Did a speed test with comcast using the old surfboard docsis2.0 and got terribly slow upload/download.
Installed the new modem with docsis3.0 and reran the same test and got way better speeds. Internet games and netflix run a lot smoother.
Worth the upgrade if you are subscribing to comcast blast packages that use docsis 3.0. Also make sure you upgrade the wireless router at the same time, otherwise you'll still have a bottle neck.
