What Modems Are Compatible With Atlantic Broadband? 

Are you going to save money if you buy a third-party modem compatible with Atlantic Broadband? Will you get better performance? What modem to buy and what to look for? This article will give you answers to all those questions. We will analyze the costs and potential savings, discuss the advantages and disadvantages of using your own Atlantic Broadband approved modem, list the most important characteristics to look for, and give you some suggestions. Let’s start with some basic info about Atlantic Broadband. 

Short Overview of Atlantic Broadband Internet Service

Atlantic Broadband is a small internet provider that operates across the East Coast.

Like other small internet providers (RCN, for example), Atlantic Broadband has its advantages over large ISPs. The two most important ones are more affordable prices and unlimited data plans. 

Internet coverage

Atlantic Broadband is a cable internet provider. It’s available in 11 states and has the best coverage in Florida, Pennsylvania, and Mississippi. Atlantic Broadband has more than 450,000 customers. Atlantic Broadband internet, cable TV, and digital phone services are available to almost 2 million people.

Atlantic Broadband has a fiber network, too. However, their fiber internet is available to businesses (not residential subscribers).

Internet plans and prices

Atlantic Broadband offers very competitive internet plans and promotional prices. Their internet plans range from 50 Mbps (Basic Internet) to 1 Gbps (Unlimited GigaFast).

The above-mentioned prices apply only to those who opt for paperless billing and Autopay. If you don’t want to allow the Autopay option, you will have to pay an additional $10/month. 

One thing you should always have in mind when choosing your ISP is that promotional prices don’t last forever. In most cases, you will get a one-year promotion. It’s only 6 months with Atlantic Broadband. After the promotional period, the prices will be increased. The Basic plan will cost you $60/month, while the GigaFast plan will cost you $110/month. 

PlanPromotional pricesPrices after 6 months
Basic – 50 Mbps / 2 Mbps$34.99$59.99
Fast – 100 Mbps / 10 Mbps$39.99$74.99
UltraFast – 400 Mbps / 10 Mbps$39.99$89.99
GigaFast 1 Gig / 50 Mbps$59.99$109.99

Contract details

While you can get some additional discount if you sign a contract, you don’t have to sign it and you can pay your bills on a month-to-month basis. This is pretty much standard practice these days – most ISPs offer internet plans without a contract. The most important advantage of this practice is that you don’t have to pay early termination fees if you have to cancel your service. Those fees can be pretty high so, unless you are absolutely certain that you’re not going to move anywhere in the next year or two, it’s smarter not to sign a long-term agreement.  

Data caps

For heavy internet users, data caps are the biggest nightmare. Many major ISPs have already imposed data caps (AT&T, Xfinity, CenturyLink, Cox, Suddenlink). Others have imposed data caps for some (but not all) internet plans. Some providers will allow you to pay extra for the unlimited plan. Others don’t even offer unlimited plans and will charge you overage fees if you exceed the limit (usually $10 per 50 GB). 

One thing small ISPs are known and praised for is the lack of data caps (at least for now). All Atlantic Broadband internet plans come without data caps. So, you can relax and forget about overage fees. 

Note: It is worth mentioning that Atlantic Broadband tried to experiment with data caps a few months ago. They imposed a 200 GB data cap on their Basic Internet plan (50 Mbps), while the other plans were unlimited. It’s pretty obvious that Atlantic Broadband didn’t impose this cap because of some kind of congestion or whatever, but to push customers to choose more expensive plans. Luckily, Atlantic Broadband quickly gave up on this experiment.

Modem rental policy

Some things all internet providers, large and small, have in common are modem rental fees. Almost all providers charge $10-$15/month for the modem/gateway. Atlantic Broadband charges an $11 monthly fee for its gateway. 

To put things in perspective, the cumulated fee you will pay in 12 months is $132. As you probably know, ISPs don’t upgrade their equipment every year (unless you decide to upgrade your internet plan). They usually renew modems/gateways every 3-5 years. In three years, you will spend $396 (or $660 in 5 years) just on the modem fees. And you will still have to return the modem if you decide to cancel your plan. 

Additional services

Internet providers often offer some additional equipment (like gaming routers or mesh extenders) for an additional fee. Atlantic Broadband has its ‘wi-fi your way’ service. This service includes two SuperPods powered by Plume. These pods use cloud-based AI technology to extend your wi-fi coverage. The SuperPods come with the wi-fi your way app. You can use this app to install SuperPods, but also to monitor your network, adjust parental settings, grant or restrict access to your wi-fi. The Pods also come with cyber security and ad-blocking software. 

wi-fi your way

If you decide to rent the modem from Atlantic Broadband, you will get two SuperPods for free (included in the modem fee). Every additional SuperPod will cost you $5/month. 

Most people won’t need more than two Pods, but if you live in a large home (like 2,500 ft2 or larger), you may need additional Pods. One SuperPod will cover up to 1,500 ft2.

Customer satisfaction

The majority of Atlantic Broadband internet subscribers are quite happy with the service. The internet is reliable, the speeds are consistent, and the outages are rare (and even when they happen, the internet is usually back within an hour). Also, the equipment that Atlantic Broadband leases to its customers is pretty good and delivers reliable performance. 

The prices are pretty much on par with other internet providers, so we can’t say that they are much better than other ISPs.

Atlantic Broadband customer service has pretty bad reviews. Most customers complained about waiting times (in some areas, it takes more than an hour for a representative to pick up). Some customers have also stated that the representatives were rude and ‘not willing to help’. We were not surprised by these customer reviews since many other internet providers (Frontier, Suddenlink, Optimum) have a similar reputation. We are not trying to say that having bad customer service is normal or acceptable – we are just saying that it’s common. We can’t say that Atlantic Broadband is significantly worse (or better) than others. 

Am I Allowed to Use My Own Modem with Atlantic Broadband?

Yes, you are. Since the introduction of the Television Viewer Protection Act in 2019, internet service providers are not allowed to force you to rent their equipment. Instead, you can buy your own. Atlantic Broadband publishes a list (or rather lists) of approved modems for its internet service. We’ve been able to find two different lists of Atlantic Broadband approved modems and gateways on the ABB website – one with older models (DOCSIS 2.0 and DOCSIS 3.0 modems) and the other, shorter list, with newer DOCSIS 3.0 and DOCSIS 3.1 approved modems and gateways.

Still, the good news is that you can buy your own modem and that you don’t have to pay $11 every month. 

If you want better coverage and you like those SuperPods that come with Atlantic Broadband modem, you can buy them directly from Plume. The price for Pods that come with the ABB modem is $100 per pod, but you can also buy more capable SuperPods with WiFi6 ($159 per pod). Or you can try some other mesh system like NETGEAR Orbi, Google Nest, Amazon eero, Linksys Velop, etc. 

Should I Use My Own Atlantic Broadband Approved Modem? What Are the Benefits?

There are two major advantages of buying your own Atlantic Broadband approved modem –money savings and performance improvement. 

The math is simple – if we assume that your ISP upgrades your modem every three years (which is rarely the case), then you can save a lot of money if you buy the equipment on your own. 

In those three years, you would have to spend $396 just on modem rental fees. If you are subscribed to Basic Internet or Unlimited Fast (or even UltraFast), you can get a very good DOCSIS 3.0 modem for $100-$150 and a nice WiFi5 router for $150 or less. If you’re living in a small apartment or a moderately large house (1,500-2,000 ft2), you won’t even need additional extenders. So, you can get everything you need for $300 or less and save $100. 

The best thing is – you don’t have to use the equipment for just three years. Modems, routers, and gateways can last more than that, even more than 5 years. So, unless you have to buy new equipment that supports higher speeds, you can keep using the old one until it breaks and make huge savings. Spending $300 on a modem (and a router) compatible with Atlantic Broadband and using them for 5 years, will save you $364. When you put everything on paper, it becomes obvious that using third-party equipment is a more cost-efficient option than renting. 

The other advantage that has to be mentioned is improved performance. Regardless of how good the equipment provided by your ISP is, it’s rarely top-of-the-line equipment. It can be modern and up-to-date, but it’s not the best money can buy. If you need that kind of performance (if you need minimal lag for online gaming or perfect wi-fi coverage in every corner of your home), the best way to get it is using your own modem and router. 

Am I Going to Lose Some Privileges or Services if I Decide to Use My Own Atlantic Broadband Approved Modem?

The most important thing to be aware of is that you can’t send your complaints to your ISP if there’s a modem-related issue. If the modem breaks or if there’s some kind of malfunction, you can only ask the seller or the manufacturer to replace your unit. If you’re renting and something happens to your modem (excluding physical damage), you will get a new one from your ISP for free. 

One more thing that you should be aware of is that buying a modem on your own is a viable option if you’re subscribed to internet only. If you’re also subscribed to a digital phone service, there’s no guarantee that it will work, even if you buy a voice gateway (or EMTA VoIP modem).  

What to Look for When Buying an Atlantic Broadband Approved Modem?

The most important thing is to look for a cable modem because Atlantic Broadband is a cable internet provider. The next thing you should be aware of is the difference between DOCSIS 3.0 and DOCSIS 3.1 modems. DOCSIS 3.1 is more capable, supports higher speeds (only DOCSIS 3.1 supports Gig plans), but it’s also pricier. If you have enough money, go for a DOCSIS 3.1 modem. 

DOCSIS 3.0 modems will support speeds up to 600 Mbps (or up to 800 Mbps). However, this doesn’t apply to all DOCSIS 3.0 modems. That’s why you also have to pay attention to channel bonding if you’re buying a DOCSIS 3.0 modem. You have to check how many downlink and uplink channels the modem has. DOCSIS 3.0 modems with more channels will support higher speeds. The best options when it comes to DOCSIS 3.0 modems are those that feature 32×8 and 24×8 channel bonding. 

Cheaper plans (like Basic Internet and Unlimited Fast) may not require 24 or 32 downlink channels, but we still recommend getting a 24×8 or 32×8 DOCSIS 3.0 modem. Internet providers will, from time to time, upgrade your speeds, and your modem may not be able to support those speeds if you buy the cheapest 16×4 DOCSIS 3.0 modem.

If there are some unanswered questions, you can always leave us a message in the comment section below and we will answer promptly. 


Q: Can I use any modem and router with Atlantic Broadband?

A: The answer is no. You will have to look for the modem and router that support your speeds. DOCSIS 3.0 modem is simply unable to deliver Gig speeds – for that, you need a DOCSIS 3.1 modem. Theoretically, any wi-fi router will create a wi-fi network, and you’ll be able to connect to your wi-fi and surf the internet, but you won’t get speeds that you are paying for if the router doesn’t support your internet plan.

Q: Is NETGEAR CM1000 compatible with Atlantic Broadband?

A: NETGEAR CM1000 is approved by Atlantic Broadband and is compatible with their cable internet service. Besides CM1000, you have a few more Atlantic Broadband approved modems made by NETGEAR – CM1200, C7800, CAX80, CM2000.

Q: Can any modem work with any router?

A: Theoretically, it can. You will get some kind of wi-fi, you will be able to connect to the network, and you’ll be able to surf the internet. But you may not get the speeds you paid for. That’s why it’s important to properly match your modem and your router (and to match them both with your internet plan).

Q: Do I have to use the Atlantic Broadband modem?

A: No, you don’t. You have two options – rent the modem from ABB ($11/month) or buy your own modem (and router) compatible with Atlantic Broadband.

Q: Is Atlantic Broadband cable or satellite?

A: ABB is mostly a cable internet provider. It also has a fiber network, but ABB fiber internet is reserved for businesses.

Q: Can I use a router without a modem?

A: If you don’t need wi-fi, you can. But if you want to connect your wireless devices (phones, tablets, laptops) to your home network, then you definitely need a router, not just a modem. Or you can get a two-in-one device – a modem with a built-in router (aka gateway). 

Q: What is the best Atlantic Broadband approved router?

A: Our top three choices when it comes to modems/gateway compatible with Atlantic Broadband are Motorola MB8600 (best DOCSIS 3.1 modem under $150), ARRIS SBG8300 (best DOCSIS 3.1 gateway under $300), and NETGEAR CAX80 (best overall).
