ARRIS SURFboard SB6141 DOCSIS 3.0 Cable Modem Review

Written by

If you’re paying for cable Internet, you’re probably paying a separate monthly fee for the privilege of renting a cable modem from your ISP. Your ISP gets free money and you get a cable modem that might not even be good enough to hit the speed you’re paying for. If you buy your own cable modem, you can get something better and recoup the cost in as little as a year—and then start saving anywhere from $6-10 each month.

Arris surfboard sb6141 remains the cable modem we’d recommend for most people. Unlike the competition, it’s compatible with almost all of the fastest Internet plans from most major Internet providers (there are others that are compatible with as many providers, but none support most of their fastest speeds). You can move almost wherever you want and be assured that this buy-once, use-for-awhile device will still work. (Or you can switch providers if there’s a better deal in your area.)

Arris sb6141 is one of the best-rated cable modems by thousands of previous purchases, and it’s more than fast enough for the Internet speeds most Americans have. Even if you’re on a basic 25Mbps-or-slower plan (like most people), the SB6141 can help you avoid network congestion that an older modem could get stuck on. You’ll be closer to the top speeds you’re paying for. And if you ever upgrade to a faster plan, the SB6141 can handle it—with very few exceptions. It’s the most popular and well-reviewed cable modem in its class.

If you’ve had your rental modem for a while, buying the SB6141 DOCSIS 3.0 modem can even improve your Internet speed. And you can immediately benefit from faster speeds if your ISP improves service in your area.

If our pick sells out for whatever reason, Netgear’s CM400-100NAS DOCSIS 3.0 cable modem is a decent alternative. It costs a little less than our pick, and it’s also an 8×4 cable modem, but it isn’t as compatible with as many ISPs. It supports the same Internet plans as our pick on the nation’s three biggest ISPs: Comcast, Time Warner Cable, and Charter. It also works with Cox, but it’s not compatible with Suddenlink, Mediacom, WideOpenWest, or Cable One.

The ARRIS SurfBoard SB6183 is the step up from the SB6141. It supports double the download speeds of the SB6141, but few Internet plans offer that much speed. You’ll need it only if you subscribe to a plan like Time Warner’s 300Mbps Ultimate tier, found in locations like Los Angeles, New York City, and Austin. It might give you slightly faster speeds on a 100Mbps+ plan from another provider, but only if your provider’s network can use its greater bandwidth. And very few people have Internet speeds that fast anyway. The SB6141 is fast enough for almost everyone else, and it’s quite a bit cheaper. By the time most people’s cable service gets anywhere near the limits of the SB6141, next-generation cable modems will be out. It doesn’t make sense to get the SB6183 now unless you know you need it.

Arris sb6141 DOCSIS 3.0 modem is the best choice for most people right now because it’s the only one that works with most of the fastest national plans on seven of the eight biggest US cable ISPs, as well as Cox. (The odd one out is Cablevision/Optimum, which recommends modems that include VOIP functionality.) Additionally, it has many thousands of glowing Amazon reviews and a history of reliability.

The SB6141 supports eight downstream channels and four upstream channels. After network overhead, that gives you a maximum bandwidth of 304 Mbps downstream and 108 Mbps upstream. That’s a lot faster than most cable-Internet plans, but that’s okay—our pick can still help you get closer to your maximum speed by reducing the effects of network congestion.

To illustrate what we mean, suppose your ISP rents you a 1×1 cable modem for your 25 Mbps plan, but your ISP actually has an 8×4 network. If there’s network congestion on your modem’s single channel, your speeds will suffer. Switching to an 8×4 modem that uses more of your ISP’s channels is like adding extra lanes to a freeway—congestion in one channel won’t affect the speeds of the others.

That said, it’s hard to predict the performance gains you might see. Some Amazon purchasers have doubled their speeds when switching from a DOCSIS 2.0 modem (1×1) to our pick. Some didn’t get any benefit at all. It depends on your service speed and your ISP’s network congestion. But even if you don’t see a benefit now, our pick gives you the flexibility to get faster service in the future, whether you pay for the upgrade or your ISP upgrades your service for free.

Our pick also makes the most sense if you’re paying for service below 300 Mbps and aren’t maxing it out—which you can check with a quick download and upload test at any number of websites. We prefer the SB6141 over our step-up pick, a 16×4 cable modem because the SB6141 is less expensive, so you’ll recoup your money faster. Plus, you’re unlikely to get much of a speed boost—if any—over our 8×4 pick with most cable Internet plans.

Arris sb6141 DOCSIS 3.0 modem is the best cable modem for most people. This 8×4 device works with a large number of ISPs and supports most of the fastest Internet plans they offer right now. It’s also popular and has a history of reliability. Even though most people don’t pay for triple-digit Internet speeds, our pick does a great job addressing network congestion to get you closer to your plan’s maximums, without being overkill or overpriced. More important, thousands of people who have previously purchased the SB6141 praise it highly.
Depending on how much your ISP charges for your cable modem rental, you’ll be able to recoup your money in just around a year with our pick. With DOCSIS 3.1 right around the corner, it’s better to start saving money sooner with a great cable modem unless you absolutely need the increased capabilities of our step-up pick—and if you do, you’re already paying a small fortune monthly for 300Mbps Internet speeds, so the step-up’s extra cost isn’t that big of a deal for you.
