This review is also for anybody who gets confused or intimidated when shopping for a modem. We’ll go over what you need to know and which details really matter. By the end of this review, you’ll have a better idea of what cable modem is right for you.

What To Look For

There are only a few specs that you need to pay attention to when shopping for the best cable modem. We’ll go over the key specs here so you can make sense of them and shop prepared.

Modem Type - There are three different types of modem that support different standards. These standards are called “data over cable service interface specification” or DOCSIS. You have DOCSIS 1.x, DOCSIS 2.0, and DOCSIS 3.0. All of the modems on our list are DOCSIS 3.0. At this point, DOCSIS 1.x is obsolete because of the low standard for upload speeds. Uploading is when you’re putting something from your computer to the Internet. As opposed to downloading which does the opposite. The big differences between 2.0 and 3.0 is 3.0 supports multiple channels and 2.0 can only support a single channel. Speaking of channels…

Channels - Channels are different avenues within a modem. Each channel allows for uploading and downloading to and from the Internet. If you have simultaneous uploads or downloads at high speeds, you'll want multiple channels. DOCSIS 3.0 modems have four channels for uploads, and four or even eight or more channels for downloads. If you have a fast, powerful Internet plan, you could benefit from finding the best DOCSIS 3.0 modem for you.

Speed per Channel - Speed per channel is an irrelevant spec for DOCSIS 1.x and 2.0 because they’re single channel. For the best DOCSIS 3.0 modems, however, speed per channel can multiply your cap Internet speed. The speed per channel is the same as 2.0 which is 43Mbps download / 31 Mbps upload. Since 3.0 has multiple channels, it multiplies the cap speed. That makes the advantage of 3.0 clear, especially when you start doing some serious multi device tasks on it. If you’re not sure about the speed of your connection, log into your Internet provider’s website. Most of them offer a free speed test.

Zoom 5341J Quick Review

You’ve never heard of Zoom? Zoom Telephonics isn’t the best-known maker of communication devices, but they are among them. This modem in particular is another no-nonsense value proposition that’s up there with the best modems. It’s plenty quick with eight download channels and four upload channels. Comcast, Time Warner Cable, Cox Communications, Bright House Networks, Cable One, and more certify it. It even comes with a two-year warranty. The downside is that it’s kind of ugly. It has words in white print and a bright red “Z” logo in the corner. If that doesn’t bother you and you need something cheap and fast, it’s worth checking out.

Some of the Zoom's key features include:

  • Fast Internet! Up to 343 Mbps downstream and 123 Mbps upstream. Fast Ethernet port! 10/100/1000 Mbps Ethernet port connects to your Windows or Macintosh computer, router, wireless access point, HomePlug adapter, or other Ethernet-enabled device.

Price Comparison

Netgear CM500 Quick Review

This is the big brother to the Netgear CM400 we talked about earlier. The big difference is this one has sixteen channels for downloads rather than eight channels. Like the other Netgear, it has four channels for uploading. This is intended for really high performance usage. If you’re a serious gamer or run a business this could be the best Internet modem for you. It’s comparable to the outstanding Arris Motorola SB6183. But it’s worth noting that this one has a sleek black design as opposed to the bright white design of the SB6183. The two are so close in speed and quality that you could just go with whichever aesthetic you prefer.

  • Up to 680 Mbps download and upload 4k streaming speed for streaming HD videos, faster downloads, and high-speed online gaming.
  • Ideal for XFINITY Internet Blast and Extreme Customers & Time Warner Maxx customers (up to Ultimate 300 plans).

Editor's Rating:

- Type: Ethernet Cable Modem
- Download/Upload Speeds: 340 / 120 Mbps
- Channels: 8 Upload / 4 Download

Price Comparison

Linksys DPC3008 Quick Review

This Linksys DPC3008 is a moderately powered modem at a moderate price. It will be able to keep up with most high-speed Internet plans, but isn’t as powerful as the sixteen channel modems. Comcast certifies it, and it claims to be compatible with most major cable providers. While it’s an excellent modem, its simplicity is what stood out to us. It doesn’t have a ton of features that make it stand out from the crowd. It’s just a solid, honest cable modem from a reputable brand that will get the job done well. It’s a great pick if you have Comcast and want to get rid of that monthly rental charge.

Key features:

  • Eliminate monthly rental fees
  • 4x faster than DOCSIS 2.0
  • Delivers download speeds of up to 340 Mbps; upload speeds of up to 120 Mbps*
  • Gigabit Ethernet port

#6. Best Upload/Download Speed: D-Link DCM-301

This D-Link offers a lot of bang for the buck. It has eight channels for downloads and four channels for uploads making performance pretty respectable. It comes with a list of certifications from Cox Communications, Comcast, Time Warner Cable, Bright House Networks, and more. The unit has a lot of ventilation on top, keeping it running nice and cool. In classic D-Link fashion, it’s user friendly and easy to set up. It’s also an excellent value. If you want a great modem at a good price, and one that comes with multiple certifications, this is one of the best DOCSIS 3.0 modems for you.

Key specs:

  • High-Speed Internet – 8 times faster than DOCSIS 2.0.
  • Gigabit Port – 10/100/1000Mbps BaseT Ethernet port.
  • Certified and Compatible – DOCSIS CableLabs Certified®, ensuring compatibility with most major U.S. cable companies.

#7. Best Budget: Arris Motorola SB6141

Price Comparison

Arris Motorola SB6141 Quick Review

This modem is the little brother to the SB6183 we touched on earlier. The biggest difference between the two is that this one has eight download channels rather than sixteen. To the untrained eye, this unit looks exactly the same as the other Arris Motorola on our list. It has a lot of the same features like wide compatibility with internet providers. While this is a great modem, it’s fairly close in cost to the SB6183 which is one of the best cable modems on the market. The majority of us have no need for sixteen download channels over eight channels. It's cheaper and offers nearly identical specs otherwise. But, if you're looking for the more powerful unit and are willing to pay the extra 20$, you might as well get the more powerful router. Otherwise, this is another great option.

  • 8X Faster than DOCSIS 2.0
  • Download speeds up to 343 Mbps
  • DOCSIS 3.0 Cable Modem
  • 8 download and 4 upload channels
  • Supports IPv4 and IPv6 – the latest Internet standard
  • Compatible with major U.S. Cable Providers

If you're looking for a rockstar internet setup, consider combining one of our Best Cable Modems with one of our Best Wireless Routers. You won't be disappointed. Or, if you're a gamer, we've also compiled a list of the Best Gaming Routers that are tailored for the needs of the extreme gamer!
