Why y'all should trust the states
Before joining Wirecutter, Joel Santo Domingo tested and has written near PCs, networking products, and personal tech at PCMag and PC Magazine for more than than 17 years. Prior to writing for a living, Joel was an IT tech and sysadmin for small, medium, and large companies.
Who this is for
You should buy a cable modem if you're currently paying a fee to rent one from your ISP. Most ISPs accuse $x a month to rent a modem—that'south $120 a year, every year, on summit of what you lot're already paying for internet access. (Altice and Spectrum include the modem-rental toll in their electric current internet plans, just if you haven't inverse your programme in a few years, you may still be paying a rental fee; give Altice or Spectrum a phone call to meet what your current options are.) Unless you lot have gigabit-speed internet, you tin expect to pay around $60 to $ninety for a modem, which means you'll relieve money in less than a year.
Many ISPs rent out modems that double as wireless routers, which means that if y'all supersede your rental modem with one you bought, you may also need to buy a wireless router if you lot want Wi-Fi in your house (if you lot're not sure what the divergence is between a router and a cable modem, nosotros accept 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-forepart price as depression equally $160, which means information technology pays for itself in a year and a one-half. Your modem and router should last you at least a few years if not more than, and so fifty-fifty if you become for the more expensive option, you'll still come out on top. ISP-supplied modem-router combos tend to have bare-minimum characteristic lists and poor Wi-Fi range, while standalone routers have added antennas for improve coverage, more than parental command settings, and other dainty-to-take features like guest networks and VPN servers.
| ISP | Monthly modem-rental fees (every bit of March 2021) |
| Comcast Xfinity | $xiv |
| Spectrum | $5 or no accuse |
| Cox | $x or no accuse |
| Altice/Suddenlink | $10 or $20 |
| WOW | $10 or $xiv |
| RCN | $2 to $xiii, depending on your location |
| Sparklight/Cable One | $10.50 |
| Mediacom | $12 |
(Legacy plans from Optimum, Time Warner Cable, or Lease may include a modem-rental fee depending on who your Internet service provider was before the merger. Most current Spectrum plans practice not take a divide fee. Fees electric current as of March 24, 2021.)
Don't buy a cablevision modem if you're on DSL or fiber; those technologies apply dissimilar standards and connectors. Verizon Fios lets you lot buy your own modem-router combo, but you lot have only a unmarried choice, and it'due south identical to the equipment they hire to you.
Also don't buy one if you apply your cable provider for telephone service: The models we cover here don't have phone ports. If you need one that does, check to meet which "telephony" or eMTA modems your ISP supports, and if the visitor allows y'all to purchase your own. Comcast Xfinity'due south webpage has a checkbox so you tin make up one's mind which approved modems are voice/telephone enabled, and Cox has a listing of approved modems that are compatible with their voice services. Cable 1 notes that it just supports a handful of Arris modems (including the ane it leases to you) for vocalisation service on its back up site, while WOW only supports its leased WOW! Advanced Modem for phonation. The telephony modems you can purchase are besides more expensive than regular cablevision modems.
When to supplant your quondam modem
You should go a new modem if yours doesn't support DOCSIS 3.0, the near widespread iteration of the Data Over Cablevision Service Interface Specification, which governs how cable operators evangelize high-speed cable cyberspace. If you lot'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 only DOCSIS ii.0, in which case information technology's time to upgrade. Only if you already own a DOCSIS 3.0 cable modem that supports your cyberspace plan'south summit rates, don't purchase a more powerful (and more expensive) cable modem for the sake of futurity-proofing.
The kickoff two versions of DOCSIS used only 1 downstream channel (for downloading data) and one upstream channel (for uploading information). DOCSIS 3.0 allows modems to bond multiple channels into a single data stream, giving yous 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.ii gigabit per 2nd with a 32-channel modem.
A modem's maximum speed, equally 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 hit 600-plus Mbps. Almost currently bachelor 24×eight or 32×viii modems max out at 600 Mbps or 1 Gbps, respectively. If you buy a i Gbps modem but pay for only 300 Mbps service, your download speeds are still limited to 300 Mbps. Unless y'all're on a very congested network with abiding slowdowns, you likely won't detect a huge difference from added channels on slower speed tiers.
How we picked
Nobody really reviews cable modems—it's hard, because you can't know whether it's the modem or the ISP that'south 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. Just more often than not speaking, modems either piece of work or don't.
Instead, we started our research past considering all the DOCSIS 3.0 and DOCSIS 3.ane modems that work on the nation's biggest ISPs—Comcast Xfinity, Spectrum, Cox, Optimum and Suddenlink (both endemic by Altice), Sparklight/Cablevision One, RCN, and WOW—and then narrowed the field to modems compatible with the most popular plans on those ISPs. (Altice and RCN don't publish a list of canonical modems, though, and with few exceptions wouldn't verify whether any of our picks would work with their services.)
- Compatibility: ISP compatibility is the main factor in choosing a cablevision modem. A modem either works with your Internet access provider or doesn't. The beginning thing to do is to bank check your ISP'south approved-modem list—hither's where to cheque for Comcast, Spectrum, Cox, Sparklight/Cable One, Mediacom (PDF), and WOW (PDF). If yous're lucky enough to live in an area where you can choose from multiple ISPs, the capability to bring your modem from ane provider to another is a prissy 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 equally a number, such every bit 16×4, 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 24×8 modem won't improve performance. The right cablevision modem is the ane with the right number of channels for your service tier. The average internet speed in the US is around 180 Mbps, and the fastest cablevision tier most major ISPs offering is between 100 and 1,000 Mbps (aka gigabit). If you have service ranging from 100 to 300 Mbps, a 16×iv modem will be plenty. If your internet program is over 300 Mbps, you demand a 24×8 modem or meliorate. Our summit picks will work for whatsoever plan upwardly to 600 Mbps. We don't recommend 8×4 or four×4 modems, because ISPs are phasing out support for those older models, even on lower-speed plans.
- Warranty: Most modems come with a one- or 2-year limited warranty that covers any catastrophic failure. A warranty is useful, because a company will typically replace a modem if information technology stops working due to defects. Malfunctions are non a mutual occurrence with modems, only since purchasing your own means you lot don't go a warranty through your cablevision provider anymore, the warranty is good to take in case annihilation goes incorrect.
- Price: We plant that you lot should expect to pay $60 to $fourscore for a DOCSIS three.0 modem that works with most plans and has the features you need to get the highest speeds available to you. Modems capable of full gigabit speeds are significantly pricier at $150 to $250.
- Oestrus: Read the owner reviews for almost any modem, and someone will mention that the modem gets hot. Most manufacturers list the operating temperature on modems as up to 104 degrees Fahrenheit, which is pretty hot for whatsoever 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 be a chip ugly, but that doesn't mean you should hide yours abroad in a drawer. We'll keep an eye out for reports of excessive rut-related problems with cable modems, and nosotros will update our picks as needed.
After researching all the modems currently available, nosotros landed on four contenders for 24×8 modems: the Motorola MB7621, Netgear CM600, Linksys CM3024, and TP-Link TC-7650. Nosotros also considered two popular DOCSIS 3.0 sixteen×four modems that were our previous top pick and runner-upwardly, respectively, the Netgear CM500 and TP-Link TC-7620, besides as DOCSIS 3.1 models: the Arris SURFboard SB8200, Arris S33, Motorola MB8600, Motorola MB8611, Netgear CM1100, CM1200, CM2000, and Netgear CM1000.
Our pick: Motorola MB7621
Our pick
The Motorola MB7621 is a reliable 24×8 DOCSIS 3.0 cable modem that works with all the major ISPs at the fourth dimension of this writing. It is compatible with the most commonly offered speed plans from Comcast Xfinity (up to 600 Mbps), Spectrum (up to 400 Mbps), Cox (Ultimate Classic), Suddenlink (upwards to 500 Mbps), and Sparklight/Cable Ane (up to 600 Mbps), every bit well as with WOW's 600 Mbps plan. Information technology's less expensive than comparable modems like Netgear'due south CM600 and information technology has a two-year warranty, so you can salve a bit more than coin and take your hardware covered for longer.
The MB7621 is a DOCSIS 3.0 modem with 24 downstream channels and viii upstream channels. This is plenty for most internet plans up to 600 Mbps, and many ISPs crave a 24×eight modem for their top non-gigabit plans, such as Spectrum'due south 400 Mbps plan or Cox's Internet Ultimate plan. Even though DOCSIS 3.1 has begun rolling out, that standard is backward compatible, so all DOCSIS 3.0 modems volition work with DOCSIS 3.1 service.
Although the MB7621 has solid support from every major Isp right now, double-checking your ISP's compatibility page before you purchase the modem is even so a good thought. ISPs update their modem-compatibility lists often, and they occasionally drop support for a modem with little to no warning.
Our experience over the past few years has been trouble-gratuitous. "The all-time things I can say about a cablevision modem are that it'southward fast and I never need to retrieve about it," said editor Ben Keough. "This one checks both of those boxes."
Runner-up: Netgear CM600
Runner-up
Netgear CM600
Same speeds, shorter warranty
The CM600 supports the aforementioned speeds as the MB7621, only it'south slightly more expensive and has a shorter, 1-year warranty.
Ownership Options
*At the fourth dimension of publishing, the cost was $120 .
The Netgear CM600, some other highly regarded 24×8 DOCSIS 3.0 cable modem, promises the aforementioned performance levels on the same speed tiers equally the MB7621—information technology only costs a chip more than and has a shorter, one-twelvemonth warranty. The Netgear CM600's user manual (PDF) too claims compatibility with Optimum, but if you lot have Optimum service, you should call your local Optimum client support number to bank check before you buy any modem. Owners like information technology; Amazon reviews are consistently positive.
Our long-term testing reinforces the modem's positive reviews: "The fix up with Optimum was pretty quick and easy" and "It'due south working merely fine… I haven't had any bug" says Makula Dunbar, Wirecutter'south Associate Partnerships Director.
While reviews suggest that the CM600 is a reliable modem, Netgear's included i-year warranty isn't neat considering that well-nigh 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)—so there's always a possibility of something going wrong if, for example, you don't place yours in a well-ventilated area.
Even though the CM600 has solid back up from every major ISP correct at present, double-checking your ISP's compatibility page earlier you purchase the modem is however a practiced idea. ISPs update their modem-compatibility lists often, and they occasionally drop support for a modem with little to no warning.
Budget pick: Netgear CM500
Budget selection
Netgear CM500
For plans upwardly to 300 Mbps
Our sometime acme pick is still a skilful choice if saving money is important to you, and equally long as yous oasis't upgraded to a service program faster than 300 Mbps.
A former top pick, the Netgear CM500 is still a skilful choice for the budget-minded internet user. It shares many of the same features as our top pick, including wide Internet access provider blessing, at a lower purchase cost. The trade-off is that ISP support for the CM500 usually tops off at virtually 300 Mbps instead of the 600 Mbps the MB7621 and CM600 are capable of. It is compatible with Comcast Xfinity (up to 250 Mbps), Spectrum (upwards to 300 Mbps), Cox (Ultimate program), Suddenlink (up to 500 Mbps), and Sparklight/Cable One (upwardly to 300 Mbps), also as with WOW's 500 Mbps plan. On the plus side, you lot will be fine for a while, considering DOCSIS 3.1 is backward-compatible with DOCSIS 3.0 modems. Information technology's a great pick if you don't demand your cable company's fastest plans, or if they are unavailable where you lot live.
Upgrade selection: Motorola MB8600
Upgrade pick
Motorola MB8600
For gigabit internet plans
The Motorola MB8600 is our pick if you already have gigabit internet services: It'southward the to the lowest degree expensive DOCSIS iii.1 gigabit modem, has a two-year warranty, and has a practiced design.
If you lot already accept a gigabit-speed cable cyberspace programme, or know your ISP offers 1 and lets you bring your own cable modem, the Motorola MB8600 is your best pick. It'south unremarkably less expensive than its competition, it has certifications from Sparklight/Cable 1, Cox, and Xfinity, and information technology has a two-year warranty. Because it's DOCSIS iii.one certified and supports 32×viii DOCSIS iii.0 channels, it should piece of work with other cablevision companies that have enabled Gigabit Ethernet on their networks, only as usual you should check with your individual provider. For example, RCN's website goes out of its way to say that the company isn't currently supporting the MB8600, but it also doesn't specify an approved alternative.
You shouldn't get the MB8600, or any other gigabit modem, unless you know your Internet access provider supports it today. Until your Internet access provider offers gigabit service in your area, you won't know if it'll roll out DOCSIS 3.0, DOCSIS iii.1, or fiber to your home. The MB8600 should work for the showtime ii situations, but it will be useless if they install fiber. For more than, bank check out our department about DOCSIS iii.1 and gigabit internet.
The MB8600 has four Gigabit Ethernet ports on its back panel, which aren't, as you lot'd wait, continued to a built-in router or switch—they tin't be used to connect wired Ethernet devices. The ports are hidden backside a xanthous sticker to prevent defoliation, but it'due south easy to pull it off for access. The four ports are a bit of future-proofing, as they can be turned on past your Internet service provider for link/port aggregation if and when your Isp decides to back up it. The ports tin can too be used to support two (or more) split IP addresses from your Internet service provider. However, this feature is only applicable if y'all need separate accounts in your dwelling house for business and personal or family use, coming in on the same physical coaxial cablevision. For instance, if y'all already have ii or more cable modems in your dwelling house, each servicing separate accounts. The MB8600 could consolidate these into a single box, but you'd still need separate routers for each network.
DOCSIS 3.i modems cost effectually twice as much as our master picks, which means they will have over a twelvemonth to pay off assuming 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 program—DOCSIS 3.1 networks will be uniform with our DOCSIS 3.0 picks, which means that older DOCSIS 3.0 modems will continue to work just fine, albeit at lower speeds, on newer DOCSIS three.1 networks.
Setup and activation
Regardless of which modem you lot choose, y'all'll need to actuate it once you go it. Each Internet service provider has a dissimilar activation process, but you'll need to either call the company or visit a URL to actuate your modem. Here's how to activate your new modem on Comcast, Spectrum, Cox, Suddenlink, and Sparklight/Cablevision One. You'll need to phone call WOW'south customer service line to activate your modem with that ISP.
Modem compatibility list, updated March 2021
| Cable modem | Comcast Xfinity | Spectrum | Cox | Sparklight/Cablevision One | WOW | Mediacom |

ane Suddenlink told us that all DOCSIS 3.0 modems will piece of work with the company's service, but y'all should call Suddenlink to verify compatibility earlier purchasing.
The competition
Nosotros considered the Linksys CM3024, but this 24×viii modem has a few strikes against it. It only has a one-year warranty and isn't explicitly included on many cable companies' approved modem lists. However, its most glaring drawback is that it uses the Intel Puma 6 chipset. Nosotros hesitate to recommend modems using this chipset, which The Annals reports can cause latency bug (particularly with online gaming). As of this writing Linksys has not released a firmware set up for the modem.
The Netgear CM1000 is a gigabit DOCSIS iii.one modem that is a contender for our upgrade pick. It is at times more expensive and has a shorter warranty than the Motorola MB8200, but the CM1000 is a worthy alternative if the latter is unavailable. The CM1000 has only one Gigabit Ethernet port in the back, so you won't be able to utilize link/port aggregation on this modem in the time to come.
The Arris SB8200 is some other widely available DOCSIS 3.1 modem with similar specs to the Netgear CM1000 and Motorola MB8600, and is worth considering if information technology has a similar cost as the MB8600. Information technology has a long two-year warranty, and two Ethernet ports in the back to back up connecting two routers/computers with 2 dissever IP addresses, or for link aggregation (you'll still need a compatible router).
The Arris SURFboard SB6190 and Netgear CM700 are the near widely supported options for plans that are faster than 300 Mbps but not DOCSIS iii.one. These 32×8 modems are significantly more expensive than the 16×4 modems and are overkill if you have a 600 Mbps or slower data plan. If yous're already on a gigabit data tier, we'd recommend that you just go alee and purchase a DOCSIS iii.1 modem. They are uniform with 32×viii DOCSIS 3.0 networks, and you'll be all set if or when your ISP adopts DOCSIS 3.one. These item modems also utilize the problematic Intel Puma 6 chipset, which tin can cause latency issues. While the modem makers have distributed updated firmware fixes to the ISPs, it is ultimately up to your cable company to back up 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 2 Ethernet ports, the same as the MB8600, while the concern-oriented CM1200 has four. Multiple Ethernet ports are needed to connect multi-gig 802.11ax/Wi-Fi vi routers that support link aggregation (multiple Ethernet cables connect the modem and router to back up multi-gigabit speeds, just we don't think most people will exist using this feature anytime soon). Like the other Netgear modems, they have a ane-twelvemonth warranty. The CM1100 costs about the same corporeality every bit MB6800, while the CM1200 is about $l more expensive. We'd dismiss the latter outright, every bit it'south made mainly for businesses, just the CM1100 could be an alternative to our upgrade pick, if information technology goes on sale and y'all don't heed that it has a shorter ane-yr warranty.
The Arris S33, Motorola MB8611, and Netgear CM2000 all have 2.five GbE (gigabit Ethernet) ports, which can connect to Wi-Fi vi routers that support the 2.5 GbE standard. While we considered the future-proofing each modem provides, two.5 GbE (or faster) routers and two-gigabit internet plans are even so likewise scarce for Wirecutter to recommend these modems. The MB8611 has a relatively pocket-sized price premium of about $twenty over the MB8600, merely the CM2000 and S33 are $50-eighty more expensive than the MB8600 at this fourth dimension. We'll reevaluate the modems when more than routers can support 2.5 GbE.
In the chart to a higher place, we list which of our cablevision modem contenders work with which ISPs based on data from each Internet access provider. (Optimum/Altice and Suddenlink don't provide a list of compatible modems.) Where applicable, we also include the maximum speeds that each ISP supports. Nosotros didn't include modem-router combos, because we don't recommend them.
What about DOCSIS 3.1 and gigabit internet?
DOCSIS 3.1, which our upgrade choice supports, is the side by side standard for net cablevision 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 technology of the 3.ane standard will lead to better stability fifty-fifty at slower speeds.
Nosotros 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 3.ane lies in the upgrade procedure: To introduce DOCSIS 3.1, an Internet access provider doesn't demand to upgrade its cable lines—only the hardware in its facilities. This means that more cable operators will be able to offer gigabit speeds over the side by side few years, and many already do.
You'll demand a DOCSIS iii.1 modem like our upgrade pick only if you're in one of those covered areas and you have a gigabit-speed cyberspace programme—they're expensive right at present, and you won't see faster speeds unless you pay for one of those gigabit plans. If you are in one of those areas and want to subscribe to 1 of the proposed gigabit internet plans, wait to purchase a modem until you take the plan and then that you know it's uniform. DOCSIS 3.1 is backward-compatible, so if y'all accept a DOCSIS iii.0 modem and don't plan on upgrading to gigabit speeds, the DOCSIS 3.0 modem will keep to work with your ISP.
Right now, gigabit speed is possible on 32×eight DOCSIS three.0 modems, but nosotros don't recommend buying them since they utilize the problematic Intel Puma half dozen chipset, and it'south hard to tell whether your ISP has rolled out the gear up for the chipset'southward latency bug. Our DOCSIS three.one modem pick is 32×eight DOCSIS 3.0–compliant by specification, then become a DOCSIS 3.1 modem if y'all want true gigabit speeds on any cablevision network. Sparklight/Cable I, parts of Suddenlink's coverage area, and some regional carriers support gigabit speeds over DOCSIS three.0, but it's not mutual.
Note that some DOCSIS 3.i modems advertise "upward to x Gbps" speeds. This is the theoretical limit of the DOCSIS 3.1 standard, and they are currently unreachable. In order to practise so, you would need a router with WAN port aggregation or a ii.v Gbps Ethernet port to enable speeds higher up 1 Gbps, and for at present, most ISPs list ane Gbps every bit their top speed tier for residential customers. 2 Gbps plans be, only coverage is limited, and the few plans we've seen are expensive.
Gigabit fiber cyberspace plans are growing more popular, too. Fiber is generally faster than cablevision, specially in upload speeds, merely it involves added cost for companies because it requires new cables and network compages. That installation cost is at to the lowest degree partially why Google Fiber dialed back plans for its broadband rollout. Not to worry though—other providers, including AT&T Cobweb, CenturyLink, Frontier, Verizon, and Windstream, are expanding their networks. Those who are looking to cut wires entirely out of the equation are starting to get excited about 5G wireless internet to the dwelling and for mobile use. 5G uses fiber as its backbone, but uses wireless engineering to deliver the service to homes and businesses.
As mentioned above, you shouldn't buy a DOCSIS 3.1 modem right now if DOCSIS 3.ane service isn't available in your area. Hereafter-proofing is good in theory just difficult in practice. It might audio smart to buy the best modem bachelor, but the interplay between the engineering science, your location, and the ISP means your chances of wasting money on a device that might not work in the future are higher with modems than with other types of electronics. Net providers tend to be coy with their technology and service rollouts, then it'south hard to tell when—or if—you'll see a bump in the speeds they offer. For instance, simply because some parts of Denver have access to gigabit speeds doesn't hateful the surrounding suburbs will.
What to look forward to
We surmise new modems will feature a 2.5-gigabit Ethernet port, supporting faster speeds for Wi-Fi 6 routers and mesh networks. Equally stated above, this is more than of a future-proofing move, as nearly Internet access provider plans summit out at 1-gigabit cyberspace. Nosotros'll evaluate them as they become readily bachelor.
