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?
1. Best Overall: Motorola MB7420
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.
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.

While testing the TP-Link N300, we used a number of Internet service providers (ISP) like Cox, Spectrum, Comcast, etc. and realized that it is compatible with almost all major ISPs. It supports Docsis 3.0 technology and is reliable.

The router has 8 download channels and 4 upload channels and the download and upload speeds can reach up to 343Mbps and 131Mbps respectively. We were quite happy with the fact that anyone can easily figure out how to use the device.
Buying a modem-router combo is a wise choice in our opinion as this cancels out the monthly rental fees and hence profits the user.

11. Best for Entertainment: Arris SurfBoard SB6121
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.
- Comes with 4 Ethernet ports
- Easy setup
- Truly incredible speed
- 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
12. Cheapest Option: Netgear CMD31T
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.
- Definite easy installation process
- Small, compact model
- Price is decent
- Disconnects from time to time
- Doesn’t have a wifi or router option
- Manual isn’t helpful

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.
The Netgear CMD31T is simple but packs a punch. This modem is priced well below $50 but allows smooth 150Mbps downloads.

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).

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.

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.
