Are you in search of a modem or modem/router combo compatible with Atlantic broadband? You surely don’t want an overpowered device as you won’t be able to use it to its fullest potential and you also don’t need an underpowered device, because that could cause throttling or even make your internet slow. Here’s a list of best-rated cable modems that are highly approved by Atlantic.

The Internet download speeds have continued to climb as we consume more rich media in the form of movies over the internet. The modems that could at most support 20 Mbps downloads are no longer good enough. If you have a UHD television and also run a gaming device, you are probably going to need a connection that has a stable download of 100 Mbps and much more.

Besides, the modem/router equipment you’ve received from Atlantic Cable for your subscription is just not good enough. Supplying poor quality hardware to customer premise has long been a gripe about ISPs, and it won’t be going away soon. Why not buy your own from our curated list that we prepared after thorough testing?

1. Best Overall: NETGEAR Cable Modem CM1000

We tested it extensively with Atlantic broadband in some areas and noticed download speeds upto 1 Gbps and an identical upload speed making the download and uploading of files smooth.

Setting up this modem is easy and hassle-free. Its strong, stable signal through 32 x 8 channels ensure fast streaming without any lag. Also, using Wi-Fi, you can handle streaming for multiple devices without any problem.

Look-wise, it may not be so appealing but in terms of performance, it beats others hands down. The device is well-ventilated, so it’s barely warm to touch. But, if you put it in a confined space, it will heat up as there are no internal fans that could dissipate heat.

Sometimes, the modem gets on re-setting mode on its own and will correct after some time. Users also complain that the device starts degrading very early, for some, just after 2-3 months use. The drawback of this modem is that the internet slows down after a few hours and you will need to reboot it to restore the speed.

Poor and unresponsive customer care support is another problem with NetGear. You may solicit help but it may take days to register/resolve your problem. However, most of their devices including this one doesn’t face much issue, so you don’t have to worry a lot!

An ethernet cable is also part of the package. The device uses the Docsis 3.0 platform and provides you with 8 x 4 channel bonding.

For Comcast users, the unfortunate news is the Cisco modem isn’t compatible with it. However, it seems to be most in tandem with Cox communications. It gets generally good speed from the service provider. We found it to be able to deliver 343 Mbps download and 120 Mbps upload speeds easily.

The set up is the easiest part of the entire ordeal. It’s a matter of plugging it in and connecting it. After that, simply call your cable provider and ask them to set it up on their end. On your part, you need to visit a website and simply enter the activation code and account number.

9. NETGEAR N600 WiFi Modem Router (C3700)

  • DOCSIS 3.0
  • Downstream/Upstream: 8/4
  • Download/Upload Speed: 340Mbps / 122Mbps
  • Modem/Router Combo: Yes

Netgear N600 is a modem-router based on Docsis 3.0 technology. The modem has what we call a dual-band network. It means the user will get the option for two separate networks while trying to sign in to a wireless network. There are the 2.4 GHz band and 5 GHz band signal. The 2.4 GHz is significantly slower and congested as your neighbors are probably on this network. However, the range is better for this one.

The 5 GHz has a shorter range but the speed is really fast as the traffic is low on this one. The speed actually doubles on this one so while we would call the usual speed of the modem not as fast as promised, the 5 GHz signal one is definitely satisfying. To use the 5 GHz signal, you will need a wireless card capable of connecting 5 GHz on the device too.

The best thing about the modem-router combo might be how reliable it is with 8 x 4 channel bonding. Anyone that has used modern modem and routers can attest to how easily the connection is lost. That certainly seems to not be the case with this one. With super fast downloads at 340 Mbps and uploads at 122 Mbps during our lab tests, it proved its worth.

There’s a website where you can setup SSD, wifi password and see net packets, which is quite helpful.

  • Setup is incredibly easy
  • Separate guest network
  • Intuitive menu
  • Wifi isn’t that fast
  • Only has 2 ports
  • Good range

10. Arris SurfBoard AC1750 SBG6782

  • Docsis Tech: 3.0
  • Downstream/Upstream: 8/4
  • Download/Upload Speed: 343 Mbps/  131 Mbps
  • Modem/Router Combo: Yes

We will start with the good parts of the modem-router. For one, the speed is actually really good. In testing, it reached 343 Mbps download and 131 Mbps upload speed without any hassle. In fact, we have tried testing it by downloading and uploading several videos and files at the same time. While it’s not an instant download, it does work well.

Streaming movies or series on Netflix happens quite smoothly due to 8 x 4 channel bonding on Arris SurfBoard AC1750 SBG6782. The use of Docsis 3.0 technology in this modem-router makes it fast and reliable.

Now, what disappointed us is the connection stability. The connection is lost quite frequently for anyone to shrug it off easily. While resetting it immediately works, it is pretty much a hassle to reset it every single time.

This when dual-band comes into the picture. As Arris lets you set up your channel when connecting it, we noticed ours has defaulted to the one used by a lot of our neighbors in the area. We scanned the channels and chose the one that has low traffic and the connectivity issue has subsided significantly since then.

The website allows us to look through internet packets and run diagnose too, which is a nice addition. A proper user manual would have been appreciated. 

  • Dual-band
  • Speed is excellent
  • Compatible with major cable networks
  • Doesn’t come with a user manual
  • Seems to have some heating problem
  • Wifi connection is lost frequently


Which DOCSIS 3.1 modem will last years?

The Arris Touchstone CM8200A looks like a brick and is as tough as one. It won’t be winning any prizes for great looks, but the circuitry inside is impressive. The modem works on DOCSIS 3.1 platform and, in our tests, was able to give a steady throughput of 1.5 Gbps at all times.

Which modem has the best build quality?

The Netgear CM500 is sleek, but let that not fool you. It is well built and can provide downloads of 300 Mbps for days. We tested it for a week downloading Linux distros over and over again, and the modem never blinked. It is easy to plug in a router and convert your home to a Wifi zone with this router.

Which Wifi router do you recommend?

The ARRIS SURFboard SBG6782 is quite satisfactory. It checked all the boxes and was able to perform well though we strained it to the maximum limit. The AC1750 router works well, and even though it has no external antennas could send signals across 150 ft with no drop in quality of service.

Which is the most affordable cable router?

The Netgear C3700 is an impressive device. Not only does the router have a USB port but also two Ethernet ports that allow you to connect a desktop or server if needed. We found it to be an ideal low-cost solution for streaming high definition video, gaming, using Facetime with no delay or lag.

Which is the best overall performer?

The ARRIS SURFboard SBG6900AC is stylish and also a great performer. It works with both IPv4 and IPv6 and offers beamforming. This is a new tech that focuses the Wifi signal in one direction, that of the device, instead of spreading it 360°. The front has a USB port connector making it easy to hook up an external hard drive and share content across multiple computers.


We found the Netgear Nighthawk C7000 to be the best modem and router in our test. It is capable of AC1900, and that is enough to stream 4K movies to a dozen televisions at the same time. With 16 x 4 channel bonding, it provides a secure connection.

The second place went to the unassuming but excellent Cisco DPC3010 modem. Cisco has long been known as a manufacturer of top-end telecom equipment, and this device is no different. It was capable of always-on 343 Mbps downloads without disconnecting even once from the ISP.  Of course, it comes without a router, but the price is heavily discounted.
