How We Did the Test?
Judging modems for their capability is quite difficult, since we can’t test them without having to subscribe to each subscription plan of Suddenlink. Therefore, we began the test by picking the highest-rated modems from the market. And then tested them with their compatible speed plans.
During the test, we considered the following factors to come up with the top eight best Suddenlink approved modems for your home and office networks.
Also Read: Best Comcast XFINITY Approved Modems
Technology:
Almost all the major ISPs now demand a modem with at least DOCSIS 3.0 technology that supports internet speed plans of up to 1 GB. And because Suddenlink’s compatibility condition is that the modem must support DOCSIS 3.0 and DOCSIS 3.1 technology.
We’ve ensured that our picks must offer the DOCSIS 3.0 or DOCSIS 3.1 technology for better and faster performance for your favorite Suddenlink internet plans.
5 Best DOCSIS 3.1 Powered Modems
Channels:
Due to the fact that Suddenlink no longer supports the 4×4 and 8×4 channels, we made sure that the modems we chose, support at least a 16×4 channel bonding. This can reach speeds of 600Mbps.
Warranty:
Since you are purchasing a modem of your own, you won’t get a warranty from the ISP anymore. The warranty from the manufacturer becomes necessary here. And so we’ve picked the options with at least one or two years of warranty to bear you any loss in case of the device failure.
Price:
As you finally have a look at the price tag after liking a product at the shop, we did the same. We made sure you get the highest speed, reliability, and durability for the best price.
After noticing that the product satisfies all the above-stated requirements. We checked the customer reviews for the products. And made sure that the past consumers of our picks are satisfied with their performance.
It is to be noted that none of our reviews are in any way influenced by any manufacturer or brand. And All the reviews are unbiased.

Things to Consider When Buying a Modem?
Now that you know how we carried out the test. How are you going to judge a modem to be best for your networking needs? These are certain things for you to keep in mind before we head to the list.
Compatibility:
The foremost thing to check is if the modem you’re going to buy is compatible with Suddenlink? And how would you know that? Unlike many other ISPs, Suddenlink doesn’t publish a modem compatibility list on its website.
Instead, Suddenlink has the simple conditions for the third-party modems to be compatible. And that is, it must be a DOCSIS 3.0 or DOCSIS 3.1 modem. So now the job is simple. When you go shopping, you’ll only have to look for modems with these DOCSIS versions, rather than carrying a list with you.
DOCSIS:
Which DOCSIS version will you opt for? Well, it all depends on what internet plan you’ve subscribed to. The DOCSIS 3.0 modem is best for internet plans of up to 1000Mbps. While with the DOCSIS 3.1, you can yield higher speed internet plans of up to 2Gbps.
But if you’re shopping for an internet plan of say 900Mbps, we’ll still recommend getting your hands on a DOCSIS 3.1 modem for the long run. Because of its backward compatibility with the DOCSIS 3.0 supported plans.
Also, keep in mind that DOCSIS has nothing to do with increasing your networking speed. That still depends on what internet plan you’re subscribed to.
Difference Between DSL Modem And Cable Modem – Which One Is Best?
Type:
Cable Modem or a Modem-Router Combo? This is yet another important thing to be cleared before you make your purchase. You can buy a standalone cable modem that will require a separate Wi-Fi router to complete your internet connection. Or you can buy a combo of a modem and Wi-Fi router to get dual functionality in one device.
What matters here is the performance. And we recommend a standalone cable modem for the best of it.
Channels:
Channels actually indicate the speed of your modem. Your modem’s channels should match your internet plan. Since Suddenlink has internet plans only suitable for 16×4 downstream and upstream channels, that’s the least you should look for.

Product Review
Let the list begin with our editor’s choice and the consumer’s favorite, the ARRIS Surfboard SB8200. You may have never experienced great speed, stability, and reliability all at once. But here’s what will give you a taste.
In its white-colored, light-weight plastic case, the SB8200 is differentiated from the other cable modems with the hardware change of a more reliable and effective Broadcom BCM3390 chipset instead of the Intel Puma Chipset which was used in its predecessor S6190.
The modem features the latest DOCSIS 3.1 technology with the channel bonding of 32 x 8 downstream and upstream channels. That enables you to access an internet speed of up to 2 Gbps which isn’t yet supported by Suddenlink. Upon testing, we found that the ultra HD 4K streaming and smooth gaming weren’t any tough for our top pick.
Also, configuring this robust modem was a breeze. Even if you’re not into technical stuff, you can quickly set it up and connect to the online world using the user guide and user manual included in the box. However, if you want a full-on experience of uninterrupted streaming and gaming, the SB8200 is a must-have.

Product Review
Did you know, you can get yourself a modem for half of what you’re paying as yearly rent to your ISP? Especially the ones subscribed to internet plans of up to 500Mbps. But, what modem is this cheap?
Meet the NETGEAR CM500, a budget-friendly option that performs the same as other premium options on the market. And that too, for a great price value. The CM500 is packed with the DOCSIS 3.0 and channel bonding of 16 x 4 downstream and upstream channels.
However, it is recommended with the internet plans of 300Mbps for better speeds and performance. But, Suddenlink still approves it for use with its 500Mbps plan. And for sure, it can bear that, since it worked admirably when we tested it under high traffic conditions.
Apart from that, setting up this sleek, black device is relatively simple, and it didn’t take any longer. Therefore, it’s a brilliant device for the ones using lower-speed plans and doesn’t look up to an upgrade soon.

Product Review
Another quality and speed, combined with a well-pricing modem, seeks your attention. And this time it’s a Motorola release. Rated really well by each consumer, the Motorola MB7621is a mid-range modem that pays for itself in only eight months, if you opt to buy it rather than rent.
This not-so-attractive but well-ventilated build features the DOCSIS 3.0 with channel bonding of 24 x 8 downstream and upstream channels to yield your internet plans of 300Mbps up to 600Mbps as advertised. However, in actuality, modems don’t perform the same, and you can expect it to work even better.
Because in our carried out test, where we tested it on a stressed network of high-capacity downloads and 4K streaming, the MB7621 stood out flawlessly. Other than that, in case of failure, Motorola offers two years of warranty to have you covered. That guarantees the device’s durability and is a good enough reason to make an investment.
Best Blue Ridge Approved Modems for Faster and Reliable Internet Connection
Plus Point: Unlike other modems, that require you to unplug the wire to turn it off. The MB7621 has a small power button to easily turn it on and off, making it more convenient than other modems.
| PROS | CONS |
| Comes with two years of warranty. | This one isn’t that compact. |
| Great in terms of price. | |
| Has an easy-to-use power button. | |
| Performs well, even in conditions of high usage. |

Product Review
After putting out a budget option as MB7621, Motorola seemed to have worked for the best possible performance and reliability combo, to handle the latest gig-level internet connections. And here is the result in the shape of Motorola MB8611.
Supporting the latest DOCSIS 3.1 with channel bonding of 32 x 8 downstream and upstream channels, this beast of a modem can fly you at the height of 2500 Mbps speed plans, even higher speeds than our top pick ARRIS SURFboard SB8200. This speed package is not yet available on Suddenlink’s network, and that makes it future-proof.
When we tested it with Suddenlink’s 1 GIG internet package, we observed it fetch maximum speeds and create a solid connection that didn’t drop even when we ran some large-scale downloads on several devices.
However, even if you aren’t on a 2500Mbps subscription. Because it’s backward compatible with DOCSIS 3.0 technology, you may use this lightning-fast modem with lower-speed plans. The advantage is that you won’t have to worry about it becoming obsolete anytime soon.
Setting this future-proof modem was also straightforward and easy. You just need to find the instructions that come along with it and follow them. And about its price, that isn’t so cheap. Neither would we call it expensive when we think about the features it offers. So, this one is definitely a go-for option if you want to invest once and forget about it.

But same as the MB8611, you can get the most out of this modem, even if you’re using lower internet plans because of its backward compatibility.

Product Review
Since most of you are still pondering speed plans ranging from 300Mbps to 600Mbps. And there’s nothing wrong with that as long as it’s fast enough. So we included another basic yet fast one to serve you better with such service plans, which is the ARRIS Surfboard SB6183.
ARRIS didn’t disappoint yet again by designing a modem that can compete with the best while remaining the most affordable. In terms of looks, SB6183 has a more modern appearance than the NETGEAR CM500, which is similarly priced. It is equipped with DOCSIS 3.0 with 16 x 4 downstream and upstream channel bonding.

Product Review
Enough basic cable modems. Where are the modem-router combos? We know some of you’re searching for a combo to get both aspects covered in one piece.
That’s why we haven’t forgotten to add combos for you on the list. And here is the first one: NETGEAR Nighthawk C7000. A Cable Modem Wi-Fi router with dual-band property, intended for high internet speeds.
With the AC1900 wireless router technology combined with DOCSIS 3.0 and 24 x 8 Channel Bonding, the Nighthawk C7000 can deliver up to 600 Mbps and 1300 Mbps on the 2.4 GHz and 5 GHz bands. This means that, even with high-speed plans, the modem is well-equipped to give the best possible service.
However, since the all-in-one modem doesn’t work as good as the standalone modems. We expected the C7000 to suffer on either side, too. But even with the jam-packed network, the performance of the NETGEAR Nighthawk C7000 passed all the tests.
The NETGEAR Nighthawk C7000 is a superbly built modem with outstanding features. You may have to make a huge initial investment, but later on, in the future, this purchase will prove to be a worthy investment for you.

Product Review
Coming to the last product on the list, we find another modem-router combo. But this time a Motorola build, the blazing-fast MG7700. Aimed to be compact and simple, but with the most potential, it has gained a spot in the market for the best-designed modem.
The incredible option features the DOCSIS 3.0 with 24 x 8 downstream and upstream channel bonding, enabling it to possibly reach a download speed of 1Gbps. However, if you expect a compromising experience from this low-cost alternative, you should rethink. Because the MG7700 quickly and reliably connected our dozens of wireless devices to a fast, steady connection that didn’t stutter even when traffic was heavy.
The router is an AC1900 model. Where the ‘AC’ denotes its dual-band capability, which allows it to transmit wireless communications at two frequencies: 2.4GHz and 5GHz. And provide help in minimizing the network traffic and signal interference.
Motorola MG7700 makes the most of every feature and pricing. In addition, when compared to the best-performing gateway, the NETGEAR Nighthawk C7000, the Motorola MG7700 is far less expensive and has far more advanced features for a better network. However, it works well to boost any wireless signal. With the MG7700, even the largest spaces can get covered. So, It only takes a few simple cable connections to set it up and have a super-fast home system running.
GCI Approved Modems for Fast Internet Connections
Plus Point: Motorola’s MG770 also has user-friendly features like advanced firewall protection and built-in parental control to offer an extra degree of security to your family’s networking.
| PROS | CONS |
| Supports AnyBeam Beamforming technology to extend wireless range. | Not ideal for large spaces. |
| Simple and easy installation. | |
| Has an advanced security protocol. |
Conclusion
That concludes the list. Now that we’ve detailed all the significant specifications of each Suddenlink approved modem, we hope you’ll be able to quickly choose one and say goodbye to rental expenses. However, if you’re still confused. Let’s make it easier for you and divide these eight picks into three categories.
If you’re thinking about paying at once for a future-proof modem, then the DOCSIS 3.1 supported ARRIS Surfboard SB8200, Motorola MB8611, and NETGEAR CM1000 modems are the way to go.
Or if you have a limited budget and are a subscriber to lower internet plans then NETGEAR CM500, Motorola MB7621, and ARRIS Surfboard SB6183 are the best options.
While for the ones looking for an all-in-one, modem-router combo, both the NETGEAR Nighthawk C7000 and Motorola MG7700 are worth checking out.
