After researching 88 cable modems this yr, the Arris SURFboard SB6141 DOCSIS three.zero stays the cable modem we advocate for most individuals. It is suitable with seven of the 9 largest ISPs—together with Comcast, Time Warner Cable, Cox, and Constitution—and it helps the Web speeds out there to the overwhelming majority of People. Our decide is well-liked and dependable, and it provides you probably the most flexibility for switching suppliers should you transfer some place else (or in the event you’re fortunate sufficient to have a number of ISPs to select from).

Who ought to (and should not) purchase this

In the event you’re paying a charge to lease a cable modem out of your ISP, you should purchase a cable modem. For instance, Comcast and Time Warner Cable cost between $eight and $10 per 30 days to lease a modem, so should you purchase a $70 cable modem, you will begin saving cash inside one yr. (Although some ISPs, like Constitution, combine the modem rental payment into their costs, so you will not save any cash when you purchase your personal.)

You also needs to get a brand new modem if yours does not help DOCSIS three.zero, the present iteration of the Knowledge Over Cable Service Interface Specification that governs how cable operators ship excessive-velocity Web. Should you’ve had your modem for a number of years, give the mannequin identify a fast Google search; you may nonetheless be utilizing a modem that helps solely DOCSIS 2.zero.

Do not buy our cable modem picks when you’re utilizing DSL or fiber, which use completely totally different requirements from DOCSIS. Additionally, do not buy it for those who use your cable supplier for phone service: The fashions we cowl right here do not have telephone ports. Lastly, in case your Web plan has obtain speeds of one hundred fifty Mbps or larger, you will want a better-finish modem just like the Arris SURFBoard SB6183.

How we picked

All DOCSIS three.zero modems help no less than 4 downstream channels and 4 upstream channels. Downstream channels are extra essential as a result of they influence streaming and obtain speeds—and your new cable modem ought to help a minimum of eight.

An eight&occasions;four cable modem—with eight downstream channels and 4 upstream—provides most individuals loads of overhead to improve to quicker service later. It additionally does a greater job of dealing with your ISP’s community congestion than a four&occasions;four cable modem, as a result of every channel is nearly like a separate connection: If one channel is congested, one other channel might have capability. Though Comcast recommends individuals purchase a sixteen&occasions;four modem, and Cox prefers a 24&occasions;eight mannequin, these are each overkill for many Web plans slower than one hundred fifty Mbps.

We began our analysis by going by way of all the DOCSIS three.zero modems that work with the nation’s eight largest ISPs—Comcast, Time Warner Cable, Constitution, Cablevision, Suddenlink, Mediacom, WideOpenWest, and Cable One—in addition to Cox. We did not embrace (and do not advocate) modems that double as wi-fi routers.

No one actually evaluations cable modems—it is troublesome to do as a result of you possibly can’t know whether or not it is the modem or your ISP that is accountable for slower speeds, so the few evaluations that exist aren’t very scientific. We additionally do not have the power to check a number of modems on a number of ISPs ourselves. We seemed on the Amazon critiques of those modems to ensure that individuals who owned them did not have any points with the units or their producers’ buyer help.
