Best Cable Modem for 300 Mbps

Best Cable Modem for 300 Mbps – Knowing which device is perfect for you and your preferences is essential if you want a seamless internet service.

First you need to decide if you prefer a separate Cable modem and WiFi router (two boxes) or a combo modem/router on one box. The first option is more flexible (and has better performance) while the second option is for people who want simplicity and less management overheads (and less wires in the home).


1.NETGEAR Cable Modem CM500

While we don’t expect your modem to function as a piece of art, many people are still concerned that it will be an eyesore. This particular model has a sleek and sophisticated look, though the shiny exterior can easily smudge. It also doesn’t have the best ventilation, so you will want to keep it in a cool, open area to prevent overheating. Overall, however, reviewers at Top Ten Reviews found that despite the CM500’s low price, it’s competitive with top-tier modems.

“ Netgear CM500 performed extremely well on a network stressed by running four simultaneous bandwidth-hogging applications, including three large game file downloads on a PC, XBox One, and PS4 Pro and 4K Netflix streaming,” they wrote. While it’s best running at only 300 Mbps or lower, they tested up to 400 Mbps and didn’t have issues.

2.Motorola MB8600 DOCSIS

When buying a modem, it’s imperative that you make sure it will work with either your current router or the router you plan to purchase. The Motorola MB8600 relieves you of that stress—it’s capable of connecting to any Wi-Fi router and, on top of that, has a two-year warranty.

The design is functional, if not particularly attractive, and it has good ventilation to prevent it from overheating. There’s also built-in protection against service attacks and power surges. Reviewers noted that the MB8600 was easy to set up and connect, and confirmed that it worked well with multiple ISPs.

3.ARRIS Surfboard SB6183-RB

The Arris Surfboard SB6183 was once our pick for the best cable modem thanks to its solid performance that will satisfy most home internet customers who don’t pay for high-speed service, though this older modem is harder to find these days. (As of this writing, Best Buy is selling the SB6183.) If you can track down the SB6183 at a competitive price, its two-year warranty also is a big plus.

At 5.2 x 5 x 2.1 inches, the all-white SB6183 can be tucked unobtrusively next to a router, cable box and whatever other hardware you have on hand. The coaxial-cable connector is a little too close to the power connector for my taste, but you’re likely to have to deal with that only when setting up the modem.

4.ARRIS SURFboard SB8200

The Arris SURFboard SB8200 is among the very first modems to allow users to quickly download by supporting both the new and older version of the DOCSIS system. When the SURFboard was first introduced, it seemed way ahead of its time since it supported the DOCSIS standard, which had not yet been spread among users. Most internet providers prefer using the Arris cable modems and the Arris SURFboard is a future proof modem.

The next-gen cable modem is under less risk of overheating compared to other modems. It has been completely covered with a cut-out that facilitates better airflow. The modem is very lightweight and can be easily moved from one place to another. It is also pretty small with a compact design that enables it to be tucked away in tight spaces.

5.Netgear Nighthawk

Netgear’s Nighthawk CM2000 is a high-performance cable modem with a sleek design that looks the part. It can keep up with the fastest internet plans available today—and well into the future—thanks to its support for the latest DOCSIS 3.1 standards. With two upstream and two downstream OFDM channels, you can achieve download speeds of up to 2.5Gbps and upload speeds reaching 800Mbps.

Don’t worry if your ISP doesn’t support DOCSIS 3.1 yet, though, as the CM2000 is fully backward compatible with the more common DOCSIS 3.0 technology, featuring 32×8 channel support so it can handle the fastest sub-gigabit plans too. Around the back you’ll find a 2.5Gbps Ethernet port so you can connect a compatible router like Netgear’s RAX120 or Orbi AX6000 and get the maximum possible speeds for your home network with only a single Cat 6 Ethernet cable.

6.Actiontec Verizon

Solve network connectivity issues with the Actiontec GT784WNV 300 Mbps four-port wireless router. Effortlessly compatible with all major DSL providers, this modem also provides 24 Mbps of downstream to support IPTV, and is also compatible with ADSL2+, which routinely allows you to triple the bandwidth. With 902.11n built-in Wi-Fi, you can enjoy streamlined speeds with added backwards compatibility, ensuring that older devices are always supported.

Security features on this modem include a fully customizable firewall with Stateful Packet Inspection, in addition to denial-of-service protection, intrusion detection, encryption, and content filtering. Feel secure and safe with a reliable, fast connection when you use this efficient combination DSL and ADSL2+ modem.

7.Linksys CM3024

The Linksys CM3024 is a 24 x 8 DOCSIS 3.0 cable modem with max downstream speeds up to 960 Mbps and upstream speeds of up to 122 Mbps with channel-bonding technology to maximize data-transfer efficiency. We tested it on Comcast Xfinity’s 400 Mbps speed tier, and it worked without issue while we simultaneously streamed and downloaded multiple large files.

Its performance was typical for our tests, as all the modems we tested handled the same setup with very little variation. Still, if you’re subscribed to internet speeds above 300 Mbps, the CM3024’s extra channels give it an advantage over 16 x 4 modems like the Asus CM-16.


Best Cable Modem for 300 Mbps –  As a Network Engineer, I have bought a bunch of modems and tested them against each other.

And out of these, I have concluded that the best cable modem is the Motorola MB8600, which proved itself as a reliable, high-performing modem for a good price.
