"This Best Selling Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem Tends to SELL OUT VERY FAST! If this is a MUST HAVE product, be sure to Order Now to avoid disappointment!"
Motorola's easy-to-use SB6141 SURFboard DOCSIS 3.0 Cable Modem unlocks the potential of offering innovative high-bandwidth data and multimedia services to customers. Utilizing the power of DOCSIS 3.0, the SB6141 enables channel bonding of up to eight downstream channels and four upstream channels, which allows an operator to offer its customers advanced multimedia services with data rates of over 300 Mbps for received data and over 100 Mbps when sending data.
I have Time Warner internet in the Raleigh/Durham area of NC. This is a DOCSIS 3.0 area.
My download speeds have been shockingly unreliable ever since I started my internet service about 6 months ago. It is supposed to be 20 mbit down. Sometimes, it is actually better than this (25+ for short times), but more often than not, it is much worse (at times < 5, usually around 10-12). It also fluctuates wildly on a minute-by-minute basis. One minute I'll have great speed, the next it crawls. Even during a single speed test, it would fluctuate between about 5-25 mbit.
TWC support was predictably unhelpful. The best I got from them was “that should not be happening.” I pointed out that their own FAQ page says that a DOCSIS 3.0 modem is required for my service tier (so-called “turbo”). They said no, the old DOCSIS 2.0 Motorola SB5101 they gave me was fine. I got the same BS from the “normal” reps as well as the so-called “level 3″.
I asked if they would give me a DOCSIS 3.0 modem, even though they claim it is not “required”. They said no, I would have to upgrade to “extreme,” which would add $10/month for the service and another $2.50/month for their DOCSIS 3.0 gateway.
So instead of doing that, I bought this modem (which is on the TWC approved device list). I called them, gave the MAC address, and I was up and running. When the modem connected, the downstream LED turned blue, which according to the manual, means that the channel is bonded. This is a very good thing.
With this modem, I get 20 mbit on the dot, 24 hours a day. Every speed test I have run confirms (including the 200 MB test on testmy.net). Last night, I downloaded about 15 GB of data with a sustained 20 mbit rate the entire time. It’s pretty amazing how effective it is.
My speed is never ABOVE 20 anymore, but it is NOT BELOW either. I believe that the channel bonding makes it easier for the ISP to enforce bandwidth caps, but it also makes the connection more reliable. I’ll take that deal any day.
I HIGHLY recommend this modem for TWC customers in DOCSIS 3.0 areas. Don’t believe the customer service reps — it absolutely is required. It sucks that TWC won’t provide the hardware we actually need to fully use their service, but that’s just the way it is.
As many of you, I am a Time Warner customer. I was disappointed with my bandwidth speed. I was paying for “Turbo” at an extra five dollars per month but was’t seeing an improvement (I tried on heavy and light usage days / periods). So I purchased this cable modem, after reviewing the compatible modems, on Time Warner’s site. Be sure to check the list of modems allowed by your provider FIRST.
I opted for the SB6141 DOCSIS because it is has the IPV6 addressing system, is backward compatible and its channel bonding technology to boost my bandwidth speed. The IPV4 addressing is used up (predicted to be end of this year) the internet community will be going to the new IPV6 addressing system.
Granted bandwidth is limited to the CAP set by your provider but your equipment plays a part. Before I bought this modem I was using one from Time Warner. My best speed test (using speedtest.net) was 5.94 Mbps download and 1.92 Mbps upload. As of this morning, my latest test, shows 34.35 Mbps download and 1.92 Mbps upload. The upload limit is obviously kept by Time Warner to discourage uploading of large files (music libraries ,etc.).
It is built on the DOCSIS 3.0 standard (Data Over Cable Service Interface Specification). This is the latest version of DOCSIS. It also means that it uses channel bonding technology to gain access to the unused bandwidth capacity available on your network, in effect, boosting your bandwidth speeds.
The modem has 8 download and 4 upload channels. This means that the provider can (doesn’t but could) offer data rates over 300 Mbps download and over 100 Mbps upload (at least not to home users). Each channel is capable of 40 Mbps, theoretically, for a maximum of 320 Mbps. But your provider “caps” the maximum at a much lower number. On a home system if you are getting 30+ Mbps you are doing extremely well.
I have 12 devices running off my home network so I am pleased with the results. I also bought a Cisco Linksys E2500 dual band router which basically places six on each band.
Just an FYI: You have to call Time Warner, go through the lengthy process of explaining that you have bought your own modem to replace their modem. You want to have it added to their network. You will have to provide MAC address and SERIAL number of your device, name of the modem including model number and then wait up to two days for them to make the switch. I know, ridiculous right?
Another FYI: The power light at top will be green, the second light blue, next two lights green and last light blinking orange (GigE-RJ45) unless you have Gigabit capability (offers up to 1 gig Mbps transfer speeds). You need a gigabit router, gigabit ethernet card to take advantage of the increased speed AND a provider that offers it. The GigE-RJ45 allows you to obtain Gigabit rates using the same 10/100/1000 ethernet Cat 5e or 6e cables instead of needing Fiber Optic cable. Its geared toward small to medium sized business owners.
Pros: offers AES enhanced AES encryption security, channel banding technology, GIGe-RJ45 port, compatible with EuroDOCSIS, has built-in filter to reduce interference from MoCa signals, easy to access menu, easy to set up and cost less than its predecessors.
I would definitely recommend this product and suggest upgrading to a dual band router.
The SB6141 is listed on TWC’s list of approved modems. No issues with install. Easy to access menu to view power levels. Fast and works as advertised. Highly recommend.
I just bought this modem and got rid of the SBG6580 due to it’s weak wireless signal, plus i already own a good dlink wireless router.
Called time warner cable, gave them the mac address and it was up and running in a less than a minute. It totally rocks!
TWC charged me 7 dollars a month for the sb6580 rental fee, i live in los angeles and i can confirm this new modem works with TWC internet.
One year later and this modem still kicking butt hehe ( Motorola SURFboard SB6141, Firmware SB_KOMODO-220.127.116.11-SCM03-NOSH )
I recently bought a new wireless router ( ASUS RT-N66U ) Amazing router, everything works perfect! no signal drop.
Excellent choice, perfect combination, easy to use.
This does work with Time Warner cable. I called, gave them the serial number and MAC address, and I was up and running pretty quickly. Actually, first there were two nice people who tried to help, and finally I got to talk with real tech support (this guy knew what he was doing). He said that someone had ALMOST gotten it right, but left it just short of finished. In any case, I was on the phone longer than I expected, but I was pleased that the TWC folks were polite, professional, and tried hard to get me online. Once I did get online, my speeds jumped from about 22Mbps downstream and about 2 Mbps upstream to about 30-32 down and a very steady 5 up (my plan is 30/5). What’s funny is that TWC themselves say that a DOCSIS 3.0 modem is necessary for their Extreme and Wideband plans, but they don’t supply it. The tech guy explained to me that the boot file in the modem I had recognized that it should be running flat out, based on my speeds, and that’s why I was close, but off what I was paying for.
He was friendly, but my question to TWC is this: If you KNOW that customers can’t get the speed they pay for on the Extreme and Wideband plans without a DOCSIS 3.0 modem, why not supply it?? TWC’s first speed test on my new modem showed me to be at 36 downstream, and my own speed tests later showed me at 30 or a little over (I wonder if they throttled it back based on that first test?).
In any case, this is a great modem. Even looks nice. Just be prepared with the MAC address and serial number (the P/N serial number) when you call Time Warner. My downstream speeds jumped by about 30%, and my upstream more than doubled. A great little modem that even has lights that turn blue to indicate when your downstream or upstream signals are “bonded”–the tech guy explained to me that that meant that it was working in sync with my TWC plan to get the highest speed I could get. Highly recommended.
