Why you should trust us

Who this is for
You should purchase a cable modem if you're currently paying a fee to hire one from your ISP. About ISPs charge $x a month to hire a modem—that'southward $120 a yr, every year, on summit of what yous're already paying for internet access. (Altice and Spectrum include the modem-rental cost in their current internet plans, but if you lot haven't changed your program in a few years, you may still be paying a rental fee; give Altice or Spectrum a telephone call to see what your current options are.) Unless you lot have gigabit-speed cyberspace, you lot can await to pay around $60 to $90 for a modem, which means you'll salvage money in less than a twelvemonth.
Many ISPs rent out modems that double as wireless routers, which means that if you supersede your rental modem with one y'all bought, you may also demand to buy a wireless router if yous want Wi-Fi in your house (if you're not sure what the difference is between a router and a cable modem, we have a guide for that.) Our favorite Wi-Fi router currently sells for less than $150, but you lot tin can find a decent one for around $100. That puts your total up-front cost equally low as $160, which means it pays for itself in a year and a half. Your modem and router should last you at to the lowest degree a few years if non more, so even if you become for the more expensive pick, yous'll withal come out on superlative. ISP-supplied modem-router combos tend to have blank-minimum feature lists and poor Wi-Fi range, while standalone routers accept added antennas for better coverage, more parental command settings, and other nice-to-take features similar invitee networks and VPN servers.
| ISP | Monthly modem-rental fees (equally of March 2021) |
| Comcast Xfinity | $fourteen |
| Spectrum | $v or no charge |
| Cox | $10 or no charge |
| Altice/Suddenlink | $10 or $twenty |
| WOW | $10 or $14 |
| RCN | $2 to $thirteen, depending on your location |
| Sparklight/Cable One | $10.50 |
| Mediacom | $12 |
(Legacy plans from Optimum, Time Warner Cable, or Charter may include a modem-rental fee depending on who your ISP was before the merger. Most current Spectrum plans exercise not have a split fee. Fees current as of March 24, 2021.)
Don't buy a cablevision modem if you're on DSL or fiber; those technologies employ different standards and connectors. Verizon Fios lets you lot purchase your own modem-router philharmonic, but you take only a single choice, and it's identical to the equipment they rent to you.
Also don't buy one if you use your cable provider for telephone service: The models we encompass here don't accept phone ports. If you need i that does, check to see which "telephony" or eMTA modems your Internet service provider supports, and if the company allows you to buy your own. Comcast Xfinity's webpage has a checkbox and so you tin make up one's mind which canonical modems are voice/telephone enabled, and Cox has a list of canonical modems that are compatible with their voice services. Cable One notes that information technology simply supports a scattering of Arris modems (including the one it leases to y'all) for voice service on its support site, while WOW just supports its leased WOW! Avant-garde Modem for vocalization. The telephony modems you can purchase are also more than expensive than regular cable modems.
When to supersede your sometime modem
Y'all should get a new modem if yours doesn't support DOCSIS three.0, the most widespread iteration of the Information Over Cable Service Interface Specification, which governs how cable operators evangelize high-speed cablevision cyberspace. If you've had your modem for four or five years, give the model name a quick Google search; you might still be using a modem that supports simply DOCSIS 2.0, in which case it'southward time to upgrade. Just if y'all already ain a DOCSIS 3.0 cable modem that supports your internet plan's top rates, don't buy a more powerful (and more than expensive) cable modem for the sake of future-proofing.
The first two versions of DOCSIS used merely ane downstream channel (for downloading data) and one upstream channel (for uploading data). DOCSIS 3.0 allows modems to bond multiple channels into a single data stream, giving y'all 38 Mbps per channel. Since those channels can combine, you can theoretically get up to 606 Mbps with a 16-channel modem and up to 1.2 gigabit per 2d with a 32-channel modem.
A modem's maximum speed, as the manufacturer lists it, doesn't mean all that much. Most ISPs limit 16×4 modems to around 300 Mbps fifty-fifty though in theory they can striking 600-plus Mbps. Most currently available 24×8 or 32×8 modems max out at 600 Mbps or 1 Gbps, respectively. If you buy a 1 Gbps modem only pay for only 300 Mbps service, your download speeds are still limited to 300 Mbps. Unless you're on a very congested network with constant slowdowns, y'all likely won't notice a huge difference from added channels on slower speed tiers.
How nosotros picked
Nobody actually reviews cable modems—it'south difficult, because you tin can't know whether it'due south the modem or the Internet access provider that'southward to blame for slower speeds—so the few reviews that exist aren't very scientific. We likewise don't have the capability to test multiple modems on multiple ISPs ourselves. But generally speaking, modems either work or don't.
Instead, we started our research by because all the DOCSIS 3.0 and DOCSIS iii.1 modems that work on the nation'southward biggest ISPs—Comcast Xfinity, Spectrum, Cox, Optimum and Suddenlink (both owned by Altice), Sparklight/Cable One, RCN, and WOW—and and so narrowed the field to modems uniform with the most popular plans on those ISPs. (Altice and RCN don't publish a list of approved modems, though, and with few exceptions wouldn't verify whether whatsoever of our picks would piece of work with their services.)
- Compatibility: Internet access provider compatibility is the main factor in choosing a cablevision modem. A modem either works with your ISP or doesn't. The kickoff affair to do is to check your Isp's canonical-modem listing—here'due south where to bank check for Comcast, Spectrum, Cox, Sparklight/Cable Ane, Mediacom (PDF), and WOW (PDF). If yous're lucky enough to live in an surface area where you can choose from multiple ISPs, the capability to bring your modem from one provider to some other is a dainty bonus.
- Channels: Channel bonding refers to the number of downstream (for downloading) and upstream (for uploading) channels your modem can access. Modem channels appear on the box as a number, such as 16×iv, 24x8, or 32×8. With DOCSIS 3.0, the more channels your modem has, the faster the speed, provided your ISP supports those channels. This means that if the ISP offers only 16 downstream channels in your area, using a 24×eight modem won't improve performance. The right cable modem is the ane with the right number of channels for your service tier. The boilerplate net speed in the The states is around 180 Mbps, and the fastest cable tier well-nigh major ISPs offering is between 100 and one,000 Mbps (aka gigabit). If y'all accept service ranging from 100 to 300 Mbps, a 16×4 modem volition be enough. If your internet plan is over 300 Mbps, you need a 24×8 modem or amend. Our top picks will work for any programme up to 600 Mbps. We don't recommend 8×4 or 4×4 modems, because ISPs are phasing out back up for those older models, even on lower-speed plans.
- Warranty: Most modems come with a one- or two-year express warranty that covers whatsoever catastrophic failure. A warranty is useful, because a company volition typically supersede a modem if it stops working due to defects. Malfunctions are not a common occurrence with modems, merely since purchasing your own ways you don't get a warranty through your cable provider anymore, the warranty is adept to take in case anything goes wrong.
- Price: We establish that you should expect to pay $lx to $80 for a DOCSIS 3.0 modem that works with most plans and has the features you demand to get the highest speeds available to you lot. Modems capable of full gigabit speeds are significantly pricier at $150 to $250.
- Oestrus: Read the owner reviews for almost any modem, and someone volition mention that the modem gets hot. Most manufacturers list the operating temperature on modems as upwardly to 104 degrees Fahrenheit, which is pretty hot for any electronic device. To go on your modem from overheating, make sure the vents aren't covered up and it's in an open infinite. Modems might exist a flake ugly, only that doesn't mean you should hibernate yours away in a drawer. We'll keep an eye out for reports of excessive rut-related issues with cable modems, and we will update our picks every bit needed.
Afterwards researching all the modems currently bachelor, we landed on four contenders for 24×8 modems: the Motorola MB7621, Netgear CM600, Linksys CM3024, and TP-Link TC-7650. We also considered two popular DOCSIS 3.0 16×4 modems that were our previous pinnacle choice and runner-up, respectively, the Netgear CM500 and TP-Link TC-7620, too as DOCSIS three.1 models: the Arris SURFboard SB8200, Arris S33, Motorola MB8600, Motorola MB8611, Netgear CM1100, CM1200, CM2000, and Netgear CM1000.
Our choice: Motorola MB7621
Our pick
The Motorola MB7621 is a reliable 24×8 DOCSIS 3.0 cablevision modem that works with all the major ISPs at the time of this writing. It is compatible with the nearly usually offered speed plans from Comcast Xfinity (up to 600 Mbps), Spectrum (upwards to 400 Mbps), Cox (Ultimate Classic), Suddenlink (up to 500 Mbps), and Sparklight/Cable Ane (upwardly to 600 Mbps), too as with WOW'due south 600 Mbps plan. It'due south less expensive than comparable modems like Netgear'southward CM600 and it has a two-year warranty, so y'all can salvage a bit more coin and take your hardware covered for longer.
The MB7621 is a DOCSIS 3.0 modem with 24 downstream channels and 8 upstream channels. This is enough for most cyberspace plans upward to 600 Mbps, and many ISPs crave a 24×8 modem for their top non-gigabit plans, such equally Spectrum'south 400 Mbps plan or Cox's Internet Ultimate programme. Even though DOCSIS 3.one has begun rolling out, that standard is backward compatible, then all DOCSIS three.0 modems volition piece of work with DOCSIS three.1 service.
Although the MB7621 has solid support from every major ISP correct now, double-checking your ISP's compatibility folio before you purchase the modem is all the same a good idea. ISPs update their modem-compatibility lists often, and they occasionally drop support for a modem with little to no warning.
Our feel over the past few years has been trouble-free. "The best things I tin say about a cable modem are that information technology's fast and I never demand to retrieve near it," said editor Ben Keough. "This one checks both of those boxes."
Runner-upwardly: Netgear CM600
Runner-up
Netgear CM600
Same speeds, shorter warranty
The CM600 supports the same speeds as the MB7621, just it's slightly more than expensive and has a shorter, one-yr warranty.
Buying Options
*At the fourth dimension of publishing, the price was $120 .
The Netgear CM600, another highly regarded 24×8 DOCSIS 3.0 cable modem, promises the same performance levels on the same speed tiers equally the MB7621—it merely costs a bit more and has a shorter, one-year warranty. The Netgear CM600's user manual (PDF) also claims compatibility with Optimum, only if y'all have Optimum service, you should call your local Optimum client support number to check before y'all buy any modem. Owners like it; Amazon reviews are consistently positive.
Our long-term testing reinforces the modem's positive reviews: "The set with Optimum was pretty quick and easy" and "It's working just fine… I haven't had whatever bug" says Makula Dunbar, Wirecutter's Associate Partnerships Manager.
While reviews suggest that the CM600 is a reliable modem, Netgear's included one-year warranty isn't slap-up because that virtually other modems (including the Motorola MB7621) come with a two-year warranty. Modems tend to run pretty hot—the maximum operating temperature for the CM600 is 104 degrees Fahrenheit (PDF)—and then in that location's always a possibility of something going wrong if, for example, yous don't place yours in a well-ventilated area.
Even though the CM600 has solid back up from every major Internet access provider correct at present, double-checking your Internet access provider'due south compatibility page before yous purchase the modem is however a good idea. ISPs update their modem-compatibility lists often, and they occasionally drop support for a modem with little to no warning.
Upkeep selection: Netgear CM500
Budget pick
Netgear CM500
For plans upward to 300 Mbps
Our old top pick is still a adept choice if saving money is important to yous, and as long as y'all haven't upgraded to a service plan faster than 300 Mbps.
A former peak option, the Netgear CM500 is still a adept choice for the budget-minded cyberspace user. It shares many of the same features every bit our height choice, including broad Isp approval, at a lower buy price. The merchandise-off is that ISP back up for the CM500 usually tops off at about 300 Mbps instead of the 600 Mbps the MB7621 and CM600 are capable of. Information technology is compatible with Comcast Xfinity (upwards to 250 Mbps), Spectrum (up to 300 Mbps), Cox (Ultimate programme), Suddenlink (up to 500 Mbps), and Sparklight/Cable One (upward to 300 Mbps), also equally with WOW'southward 500 Mbps plan. On the plus side, you volition exist fine for a while, because DOCSIS 3.i is backward-compatible with DOCSIS three.0 modems. It'due south a great pick if yous don't need your cable visitor'southward fastest plans, or if they are unavailable where y'all alive.
Upgrade pick: Motorola MB8600
Upgrade choice
Motorola MB8600
For gigabit cyberspace plans
The Motorola MB8600 is our selection if you already have gigabit internet services: It's the to the lowest degree expensive DOCSIS iii.1 gigabit modem, has a 2-year warranty, and has a skillful design.
If you already take a gigabit-speed cable internet programme, or know your ISP offers 1 and lets you bring your own cable modem, the Motorola MB8600 is your all-time option. It's usually less expensive than its competition, information technology has certifications from Sparklight/Cable One, Cox, and Xfinity, and it has a ii-year warranty. Considering it's DOCSIS three.1 certified and supports 32×8 DOCSIS iii.0 channels, it should work with other cablevision companies that have enabled Gigabit Ethernet on their networks, but as usual you should check with your individual provider. For example, RCN'southward website goes out of its way to say that the company isn't currently supporting the MB8600, just it likewise doesn't specify an approved alternative.
You shouldn't become the MB8600, or any other gigabit modem, unless you know your Isp supports information technology today. Until your ISP offers gigabit service in your area, you won't know if it'll roll out DOCSIS iii.0, DOCSIS 3.one, or cobweb to your home. The MB8600 should work for the first two situations, but it will be useless if they install fiber. For more, bank check out our section about DOCSIS 3.1 and gigabit net.
The MB8600 has 4 Gigabit Ethernet ports on its back console, which aren't, as you'd expect, connected to a born router or switch—they tin can't be used to connect wired Ethernet devices. The ports are hidden behind a yellow sticker to prevent confusion, but it's easy to pull it off for access. The iv ports are a bit of future-proofing, equally they can be turned on by your Isp for link/port aggregation if and when your Internet access provider decides to support information technology. The ports can likewise be used to support two (or more) separate IP addresses from your Internet service provider. However, this feature is simply applicable if y'all need split accounts in your home for business concern and personal or family use, coming in on the same concrete coaxial cable. For example, if you already have two or more cable modems in your home, each servicing divide accounts. The MB8600 could consolidate these into a single box, just you'd still need separate routers for each network.
DOCSIS 3.ane modems cost around twice as much as our main picks, which means they will take over a yr to pay off bold a modem rental fee of $10 a month. Don't buy one just for the sake of future-proofing, or if you use a slower programme—DOCSIS three.1 networks will be compatible with our DOCSIS three.0 picks, which ways that older DOCSIS 3.0 modems will keep to piece of work but fine, albeit at lower speeds, on newer DOCSIS 3.1 networks.
Setup and activation
Regardless of which modem you lot choose, you lot'll need to activate it once yous get information technology. Each Internet access provider has a different activation process, only you'll need to either call the company or visit a URL to activate your modem. Hither's how to activate your new modem on Comcast, Spectrum, Cox, Suddenlink, and Sparklight/Cable One. You'll need to phone call WOW's customer service line to activate your modem with that ISP.

1 Suddenlink told the states that all DOCSIS three.0 modems will work with the company's service, but y'all should call Suddenlink to verify compatibility before purchasing.
The contest
We considered the Linksys CM3024, merely this 24×8 modem has a few strikes against information technology. It only has a one-yr warranty and isn't explicitly included on many cable companies' canonical modem lists. However, its most glaring drawback is that information technology uses the Intel Puma 6 chipset. We hesitate to recommend modems using this chipset, which The Register reports can cause latency issues (especially with online gaming). As of this writing Linksys has not released a firmware fix for the modem.
The Netgear CM1000 is a gigabit DOCSIS 3.1 modem that is a contender for our upgrade option. Information technology is at times more expensive and has a shorter warranty than the Motorola MB8200, only the CM1000 is a worthy culling if the latter is unavailable. The CM1000 has only one Gigabit Ethernet port in the back, and then you won't be able to use link/port assemblage on this modem in the future.
The Arris SB8200 is another widely available DOCSIS 3.ane modem with similar specs to the Netgear CM1000 and Motorola MB8600, and is worth because if it has a similar price every bit the MB8600. It has a long 2-year warranty, and two Ethernet ports in the back to support connecting 2 routers/computers with two divide IP addresses, or for link aggregation (you'll still need a uniform router).
The Arris SURFboard SB6190 and Netgear CM700 are the most widely supported options for plans that are faster than 300 Mbps but non DOCSIS 3.i. These 32×viii modems are significantly more expensive than the 16×iv modems and are overkill if you lot have a 600 Mbps or slower information plan. If yous're already on a gigabit data tier, we'd recommend that you just go alee and buy a DOCSIS 3.1 modem. They are compatible with 32×8 DOCSIS three.0 networks, and you lot'll be all set if or when your ISP adopts DOCSIS 3.1. These particular modems too employ the problematic Intel Puma 6 chipset, which can cause latency bug. While the modem makers have distributed updated firmware fixes to the ISPs, information technology is ultimately up to your cable company to support the modem.
The Netgear CM1100 and CM1200 modems are DOCSIS three.1, and like the Motorola MB8600, both are rated for multi-gigabit internet plans. The CM1100 features ii Ethernet ports, the same every bit the MB8600, while the business organization-oriented CM1200 has 4. Multiple Ethernet ports are needed to connect multi-gig 802.11ax/Wi-Fi six routers that support link aggregation (multiple Ethernet cables connect the modem and router to back up multi-gigabit speeds, but we don't think most people will be using this feature anytime soon). Like the other Netgear modems, they have a ane-twelvemonth warranty. The CM1100 costs nearly the same amount equally MB6800, while the CM1200 is about $50 more expensive. We'd dismiss the latter outright, as information technology's made mainly for businesses, but the CM1100 could be an culling to our upgrade pick, if it goes on sale and y'all don't heed that it has a shorter one-year warranty.
The Arris S33, Motorola MB8611, and Netgear CM2000 all take two.v GbE (gigabit Ethernet) ports, which can connect to Wi-Fi 6 routers that support the 2.v GbE standard. While we considered the future-proofing each modem provides, 2.five GbE (or faster) routers and 2-gigabit internet plans are still besides scarce for Wirecutter to recommend these modems. The MB8611 has a relatively small price premium of virtually $20 over the MB8600, but the CM2000 and S33 are $l-80 more expensive than the MB8600 at this time. We'll reevaluate the modems when more routers can support ii.v GbE.
In the chart above, we listing which of our cable modem contenders work with which ISPs based on information from each ISP. (Optimum/Altice and Suddenlink don't provide a listing of compatible modems.) Where applicative, we also include the maximum speeds that each Isp supports. Nosotros didn't include modem-router combos, considering nosotros don't recommend them.
What nigh DOCSIS 3.1 and gigabit internet?
DOCSIS 3.i, which our upgrade choice supports, is the adjacent standard for internet cable modems and ISPs. It promises speeds of upward to 10 Gbps, increased download efficiency, and better queue management for large downloads. The people behind DOCSIS say that the improved engineering science of the iii.i standard will lead to better stability even at slower speeds.
We spoke with Belal Hamzeh, vice president of wireless technologies at CableLabs, the company that came upwardly with DOCSIS, and he pointed out that a big strength of DOCSIS three.one lies in the upgrade process: To introduce DOCSIS 3.ane, an Isp doesn't need to upgrade its cablevision lines—only the hardware in its facilities. This means that more cable operators will be able to offer gigabit speeds over the next few years, and many already practise.
Yous'll need a DOCSIS 3.ane modem like our upgrade pick simply if y'all're in 1 of those covered areas and y'all have a gigabit-speed cyberspace plan—they're expensive right now, and you won't encounter faster speeds unless you pay for ane of those gigabit plans. If you are in ane of those areas and desire to subscribe to one of the proposed gigabit internet plans, wait to purchase a modem until you accept the plan and then that you know it's compatible. DOCSIS 3.1 is backward-compatible, so if you lot have a DOCSIS 3.0 modem and don't program on upgrading to gigabit speeds, the DOCSIS 3.0 modem will go along to piece of work with your ISP.
Right now, gigabit speed is possible on 32×8 DOCSIS iii.0 modems, just we don't recommend buying them since they use the problematic Intel Puma half-dozen chipset, and information technology's difficult to tell whether your ISP has rolled out the prepare for the chipset'southward latency problems. Our DOCSIS iii.1 modem selection is 32×8 DOCSIS 3.0–compliant past specification, so get a DOCSIS 3.1 modem if yous desire truthful gigabit speeds on any cablevision network. Sparklight/Cable One, parts of Suddenlink'due south coverage area, and some regional carriers support gigabit speeds over DOCSIS 3.0, only it'due south not common.
Note that some DOCSIS iii.ane modems advertise "upwards to x Gbps" speeds. This is the theoretical limit of the DOCSIS 3.1 standard, and they are currently unreachable. In lodge to practice so, you lot would demand a router with WAN port assemblage or a 2.5 Gbps Ethernet port to enable speeds above 1 Gbps, and for now, most ISPs listing one Gbps as their top speed tier for residential customers. ii Gbps plans exist, simply coverage is limited, and the few plans we've seen are expensive.
Gigabit cobweb cyberspace plans are growing more popular, too. Fiber is generally faster than cable, especially in upload speeds, merely it involves added cost for companies because it requires new cables and network architecture. That installation price is at least partially why Google Cobweb dialed back plans for its broadband rollout. Non to worry though—other providers, including AT&T Fiber, CenturyLink, Borderland, Verizon, and Windstream, are expanding their networks. Those who are looking to cut wires entirely out of the equation are starting to go excited almost 5G wireless internet to the home and for mobile apply. 5G uses fiber as its backbone, but uses wireless technology to evangelize the service to homes and businesses.
As mentioned above, you shouldn't buy a DOCSIS 3.i modem correct now if DOCSIS 3.1 service isn't available in your area. Hereafter-proofing is good in theory but hard in practice. It might sound smart to buy the all-time modem bachelor, merely the interplay between the technology, your location, and the Internet service provider ways your chances of wasting coin on a device that might non work in the future are higher with modems than with other types of electronics. Net providers tend to be coy with their engineering science and service rollouts, so it's difficult to tell when—or if—you'll come across a bump in the speeds they offer. For example, just considering some parts of Denver take admission to gigabit speeds doesn't mean the surrounding suburbs will.
What to expect frontward to
We surmise new modems will feature a two.5-gigabit Ethernet port, supporting faster speeds for Wi-Fi 6 routers and mesh networks. As stated higher up, this is more of a futurity-proofing move, as virtually Internet access provider plans elevation out at one-gigabit internet. Nosotros'll evaluate them as they get readily available.
