We tested 41 different Suddenlink approved modems and modem/router combos from known brands in various locations. After various tests, here’s a list of 12 highly compatible models that work really well. Not only have we listed them, but we’ve also added detailed reviews of each one to help you find the perfect equipment for your networking needs. Shall we begin with the list?

  • Technology: DOCSIS 3.0
  • Downstream/Upstream Channels: 16 x 4
  • Download/Upload Speed: 686Mbps / 123Mbps
  • Modem/Router Combo: No

Despite being one of the premier Internet service providers, Suddenlink isn’t actually known for its collection of rental modems. Therefore, if you have subscribed to any of the mid-range Suddenlink internet plans, it might just be the right time to opt for the affordable and feature-packed Motorola MB7420.

Starting off, this is one of the more compact modems to feature on the list, best characterized by an excellent UI and the revolutionary color-coded panel. Moreover, for any Suddenlink internet plan amounting to 300Mbps, this is one of the best gadgets on the market. However, you can also consider getting the same for other cable ISPs like Cox, Comcast, Time Warner, BrightHouse, and more.

Before coming to the modem performances, it is the compact and upright design of the Motorola MB7420 that comes across as a standout performer. Besides, the gadget takes minimum shelf space and even boasts of excellent cooling performances, courtesy of the strategic vents in play. Furthermore, the rugged chassis is perfectly complemented by the vibrant indicator lights, which are good at helping you determine the quality of connections.

As far as the modem performances are concerned, the Motorola MB7420 is a better option in the retail space, especially when download and upload speeds are concerned. While the DOCSIS 3.0 tech is at least 16 times faster than the preceding DOCSIS 2.0, the 16 x 4 channel bonding support furthers the quality of connections.

Not just that, the modem is also suitable for high-end gaming on a laptop and even streaming your gameplay on the platforms like Twitch.

While the modem promises maximum download speeds of up to 686Mbps, we tested the same with a 300Mbps Suddenlink internet connection to reach speeds close to 250Mbps. For the given connection, the Motorola MB7420 assumes decent upload speeds of up to 70Mbps, instead of the highest potential of up to 123Mbps. Coming to the port arrangement, you get access to one Gig Ethernet LAN port followed by a coaxial connection and the aesthetically placed power input.

The modem is also easy to set up and compatible with almost every wireless router in the retail space. Therefore, if you are actually looking for a reliable modem that can be scaled for basic and mid-speed Suddenlink connections, the Motorola MB7420 is one of the better gadgets to invest in.

During our use, we were able to experience a connection that was reliable enough for movie watching and online gaming. It is capable of 400Mbps downloads and 25Mbps uploads over 24 x 8 channels of data transfer.

WiFi coverage is another impressive factor. The Docsis 3.0 platform based modem-router boasts of 1800 sq. ft. coverage with its beamforming technology and amplified antennas.

In addition to that, it supports both WPA/WPA2 as well as WEP wireless security protocols.

Cons
Cons
  • Connectivity issues
  • Less clarity over safety protocols
  • Consistent use leads to overheating
  • Technology: DOCSIS 3.0
  • Downstream/Upstream Channels: 4 x 4
  • Download/Upload Speed: 172Mbps / 132Mbps
  • Modem/Router Combo: Yes

The Arris SurfBoard SB6121 is a Docsis 3.0 based modem-router combo. The model has different options for speed and channel if you are willing to pay more but even the minimum option one has amazing speed. It easily hits the 172Mbps and 132Mbps download and upload speed limit and even surpasses it. Of course, it is still somewhat dependent on your ISP.

While we weren’t particularly bothered by the blue LED indicator lights, some users have complained about it before. We have also noticed some dissatisfaction with the signal. What we noticed is that the modem takes better to new wiring. The wifi signal is overall strong and the 4 x 4 channel bonding is stable.

The setup and installation process isn’t much of a problem. As long as you understand where to plug in what, you should be alright. The manual does a good job of explaining the initial steps as well. However, it doesn’t really go more in-depth than that. So, if you’re not a tech expert who wanted to tinker with the channel and speed a little, you will need outside help.

Pros
Pros
  • Comes with 4 Ethernet ports
  • Easy setup
  • Truly incredible speed
Cons
Cons
  • Bright LED lights that can annoy the user
  • Old wiring can mess up the signal
  • Isn’t user-friendly for people who don’t understand tech
  • Technology: DOCSIS 3.0
  • Downstream/Upstream Channels: 4 x 4
  • Download/Upload Speed: 150Mbps / 150Mbps
  • Modem/Router Combo: No

If you are looking for an affordable modem, then the Netgear CMD31T would be a likely candidate for your purchase.

The modem has a steady upload and download speed of 150Mbps. It is surprisingly fast. We have tested the speed by streaming and downloading a couple of videos and it seems to do everything without any lag.

Installing the modem isn’t much of a problem. You just have to send the numbers to your ISP so they can activate it and on your end, you have to plug it all in the right way. However, it’s impossible to decipher how easy the installation is because of how bad the instruction guide is. It doesn’t do a good job of explaining anything and whether you understand tech or not, it will get you confused.

As of now, the modem doesn’t have a built-in router. So, if you need an internet connection with wifi in your home, this one isn’t for you. The Netgear CMD31T uses Docsis 3.0 technology and has 4 x 4 channel bonding allowing fast transfer of data.

Further, we were quite happy with the price range. If we compare to the counterparts in the market, this one offers more range than the others.

Pros
Pros
  • Definite easy installation process
  • Small, compact model
  • Price is decent
Cons
Cons
  • Disconnects from time to time
  • Doesn’t have a wifi or router option
  • Manual isn’t helpful

Frequently Asked Questions

If the budget was not a concern, which would you advise?

Without any hesitation, we would ask you to buy the ASUS CM-32. It is priced at $200 but packed with the latest features and has a very powerful Wifi router. In fact, it does not cost more than a modem and a separate high-quality Wifi router.
On the other hand, you get the convenience of an all in one device that is capable of 1.3Mbps downloads and sending data uniformly through your home to every device.

Which is a no-frills device for Suddenlink that you suggest?

The Netgear CMD31T is simple but packs a punch. This modem is priced well below $50 but allows smooth 150Mbps downloads. Don’t sneer because that is enough speed to stream not one but four UHD films at the same time. We tested it for many days and found it to be an aesthetically pleasing, affordable, and capable device.

I want a not very pricey top of the line modem and Wifi combo. Which should I go for?

The Arris SURFboard SBG6580 works on the DOCSIS 3.0 platform that was capable of sustaining well over 100Mbps during our rigorous testing. It has four Ethernet ports and a dual-band Wifi that takes care of most homes with 3-5 rooms (a distance of 100 ft).

I want a stylish and capable router with no ugly looking antennas.  What do you suggest?

The Netgear C7000 Nighthawk has no external antennas and is capable of AC1900 Wifi. It is certified by the manufacturer for 400 Mbps speed, and we verified it. Powered by internal antennas, the router is capable of transmitting across a medium-sized home without any lag.

Is there a DOCSIS 3.1 modem in your line up?

The Netgear CM1000 is capable of 1000 Mbps+ downloads and is priced attractively at $124. The Genie app is brilliant and allows you complete control over your device by logging in through a browser.

Verdict 

The Arris SurfBoard SBG7400AC2 was our unanimous top choice. Priced quite low, it has McAfee anti-malware protection and looks good in matte black with pale blue LEDs. It offers beamforming that focuses the Wi-Fi signal towards a device instead of spreading it omnidirectionally. There are plenty of Ethernet ports and one USB that allows you to connect to a wired network.

The runner up was the Netgear C3000 N300 modem router. With N300 Wifi, it can support up to 300 Megabits/sec, which is more than enough for most families. The innovative AirPrint feature allows you to print directly from any iOS device and a smart home network manager with an intuitive interface.
