7 Best Suddenlink Compatible Modems in 2022 [For All Plans]

In search of a Suddenlink compatible modem?

It doesn’t matter whether you’ve subscribed to the fastest Suddenlink 1 Gig or are on the mid-end Suddenlink Internet 400 or even the slow Internet 200 plan, you’ll be able to find the best modem for Suddenlink for all use-cases in the below list.

You must be knowing that you can rent a modem for a $10/month equipment lease (it also gets you a free modem upgrade, but you don’t really need an upgrade for the next 3-4 years, unless you switch to a faster service pack.) Besides, you can get a gigabit modem for 2 years of the rental fee. Also, I’ve done calculations and have come to a conclusion that buying your own modem is better than renting one.

To make sure that the list is accurate, I’ve checked with the Suddenlink’s technical team and made sure that the listed modems are certified for Suddenlink. However, you should make sure that the device you get is suitable for your subscribed internet pack. For instance, you can’t use a cheap modem on a gigabit plan.

7 Best Suddenlink Compatible Modems in 2022

It doesn’t matter which service package you’ve subscribed to, what your requirements in a modem are, whether you need gigabit-speed support or want a standalone cable modem or are looking for a modem/router combo. I’ve made this list in such a way that you’ll surely find a suitable device for your needs.

1. Best for Suddenlink 1Gb: Motorola MB8600

Are you subscribed to Suddenlink Internet 1 Gig service pack? The Motorola MB8600 is a future-ready DOCSIS 3.1 modem that’s compatible with Suddenlink. It can handle gigabit download and upload speeds without any trouble.

Suddenlink, as a cable internet service provider, offers a wide range of internet plans for its highly diversified clientele. However, if you are on Suddenlink and planning to get the 1Gbps home or office internet connection, the Motorola MB8600 is the best modem to invest in.

I even considered comparing this modem with the less powerful MB7621 and identified the MB8600 to be a much better option, owing to the additional 8 downstream channels and higher theoretical throughput.

Which Suddenlink plan is best managed by this device?

If you want to purchase the MB8600, getting on the Gig internet plan is the best possible option. As it is a powerful device with a competitive price tag, only a 1000Mbps plan or something higher would justify its inclusion.

The modem is also compatible with: Xfinity, Spectrum, Cox, WOW! Internet, and other ISPs.

Speed & Channel Bonding

The MB8600 allows you to reach maximum download speeds of up to 950 Mbps, provided you are on a gigabit internet plan. Contributing largely to the higher speed cap are the DOCSIS 3.1 network standard and the 32×8 channel bonding support.

Since, Suddenlink doesn’t offer DOCSIS 3.1 at all places, the extra amount for that technology can seem a little pricey. But then, being one of the best DOCSIS 3.1 modems, it is a reliable future-proof networking equipment for most individuals or businesses.

Note: It’s backward compatible with DOCSIS 3.0

Hardware & Performance

If you are interested in the hardware setup pertaining to the MB8600, it is the ARM chipset that calls the shots. The impact on modem-specific performances is quite obvious as I experienced minimal latency for MOBA and FPS games.

The Broadcom processor also makes room for the AQM enhancement, which is good enough for prioritizing demand-specific tasks, like video conferencing, twitch streaming, and more.

Design & Build

Coming to the aesthetics, the MB8600 from Motorola looks great and assumes a vertical layout that measures 9.65 x 8.8 x 2.55 inches. Plus, the product comes in black and weighs close to 1.2 pounds. Not to mention the inclusion of 10 LEDs and one Gig-speed Ethernet port for helping you set up wired or router-specific connections.

Why is it good for Suddenlink?

According to my analysis and testing results, I believe that the Motorola MB8600 is the best modem for Suddenlink 1 Gig Internet plan, owing to the DOCSIS 3.1 support.

Also, the topmost place is justified as compared to some of the other products on the market, courtesy of the ever-reliable processor and the Active Queue Management functionality for cutting through congestion.

2. Best From Arris: Arris Surfboard SB6190

For those interested in a mid-range modem, the Arris SB6190 is one of the better options to consider especially in 2022. I like this modem over others as it doesn’t invest in the DOCSIS 3.1 technology to try and make this a future-proof device and instead focuses on offering 32 downstream channels for covering most speed-specific loopholes.

Which Suddenlink plan is best managed by this device?

I would clearly recommend this product for the Gigabit and 400Mbps internet plans from Suddenlink. However, you need to understand that as the speeds are capped at 600Mbps, you wouldn’t be getting more for the Gigabit internet plan, unless you set up wired connections.

Also, I would like you to consider this Suddenlink certified modem even for Comcast Xfinity, Spectrum, and a handful of other cable ISPs.

Speed & Channel Bonding

The SB6190 from Arris allows you to reach 390Mbps of download speeds, when on the Suddenlink 40Mbps plan. However, for the modem to promise such speeds, you would need to pair it with a standard, mid-range router.

Also, the DOCSIS 3.0 standard is of immense help as it allows the modem to exhibit 32×8 channel bonding support. The availability of 8 upstream channels also allows this modem to promise upload speeds of up to 20Mbps for the 5GHz band when connected to a router.

Hardware & Performance

The SB6190 is more like a standard modem with an ARM chipset driving the proceedings. The performance, on the other hand, is top-shelf as the product ensures minimal online gaming latency and even supports 4K streaming without any kind of lag.

Design & Build

The aesthetics are pretty streamlined with  SB6190 making way for a 0.75-pound heavy chassis and overall product dimensions reaching out to 6.4 x 2 x 8.7 inches. However, I was most impressed with the matte black, plastic-clad chassis that exhibits a heat-dissipating design and even makes way for 4, accurate LEDs.

Plus, there is one Ethernet port to work with, provided you want to set up a router or rely on wired connections for getting Gig-level speeds on your PC.

Why is it good for Suddenlink?

I feel the Arris SB6190 strikes a great balance between the number of channels and networking technology driving the performance. This makes it good enough for almost every Suddenlink internet plan, regardless of the rated throughput.

Also, the cost-to-ownership ratio makes it a better choice, as compared to some of the other products on the list.

3. Best Suddenlink Modem/Router Combo: Netgear C7000

While trying this device, I even tried the Netgear CM1000 with Suddenlink 1 Gig plan and it did connect, but due to some reasons there were a few connectivity and speed issues, that’s why I decided to remove it from my previous suggestions. The C7000 on the other hand worked really well.

The Netgear C7000 might look like a mid-range modem-router combo but it certainly lives up to the expectations that you have from the mid-tier and even high-end Suddenlink internet plans. Also, I feel that for the given price, there aren’t many better combos in the market as compared to the C7000.

For those who are still using the C6900, this has to be the perfect time to upgrade, courtesy of the better throughput and an additional USB slot, as featured by the C7000.

Which Suddenlink plan is best managed by this device?

Personally, I would recommend the Netgear C7000 for the Suddenlink Internet 400 plan. However, you can also pair it with the Gigabit plan but the speeds will then be capped at 600Mbps. You can even use this product for Cox and Comcast internet plans.

Speed & Channel Bonding

As far as the speed estimates are concerned, the C7000 allows you to reach 400Mbps with ease, provided you have the compatible plan on you. Also, as it is a combo, you can even expect it to handle the higher bandwidth plans better, owing to minimal attenuation.

The DOCSIS 3.0 technology and the 24×8 channel bonding support ensure the higher speed capping for certain Suddenlink plans. Plus, the routing end of this product is capable of assuming maximum dual-band wireless speeds of up to 1900Mbps.

However, when tested with the 400 Mbps plan, I was able to churn out 395Mbps download speed on the 5GHz band, followed by 22Mbps of upload speeds. The 2.4GHz speeds were restricted to 182Mbps and 12Mbps, for downloads and uploads, respectively.

Hardware & Performance

When it comes to the hardware setup, the C7000 features a dependable chipset with a clock speed limit of up to 1.6GHz. The SoC clubbed with 256MB of RAM is good enough to boost response times and signal consistency of the wireless and wired connections.

Netgear also incorporates 128MB of flash memory, which is good enough for storing the firmware updates and device settings to make configuration easier than ever. When it comes to product-specific performances, C7000 brings Beamforming+ support into the mix followed by simultaneous and concurrent dual-band support.

Design & Build

From the aesthetic perspective, the C7000 isn’t the sleekest device in the market, as it measures 9.66x 8.31 x 1.7 inches. Also, it is on the heavier side with 1.60 pounds’ worth of heft to deal with. Next in line is the black-colored chassis followed by the availability of 4 high-speed Ethernet ports and one standard USB 2.0 port for supporting data transfer across networks.

Why is it suited for Suddenlink?

The existence of 24 downstream channels and concurrent wireless support makes it the perfect modem-router combo for the 400Mbps Suddenlink internet plan. However, I chose to place the Netgear C7000 in the third position owing to the exceptional value for money that it offers to professionals and budget users.
