Best Frontier [FiOS] Approved & Compatible Modems

In this article, you will find the best-approved modems for Frontier DSL and the best router for Frontier FiOS.

Frontier Approved Modems

As a Network Engineer, I have researched and talked with Frontier to conclude which modem is best for their internet. 

And I have deduced that the Netgear D6400-100NAS is the best modem for most Frontier customers. 

That said, it will not work for everyone since it doesn’t work with bonded DSL. Because when you buy a modem for Frontier, the modem needs to support your type of DSL.

To determine your DSL type, either ask Frontier or look at your plan.

Top 3 Frontier Approved Modems

Here are the 3 best frontier-approved modems.

  2. Actiontec C3000A (Best Performer)

3 Best Frontier Compatible Modems 

Here are short overviews of the top 3 Frontier compatible modems (for Frontier DSL). 

#1 Netgear D6400-100NAS (Editor’s Choice)

  • Type: Modem/Router Combo
  • Modem Technology: ADSL/ADSL2+, VDSL/VDSL2 & Fiber
  • Recommended for speed: 940 Mbps or below
  • Wi-Fi Technology: 802.11 ac
  • Warranty: 1 year 
  • Chosen as: Best Overall

The Netgear D6400 will work with any type of ADSL and VDSL that are not bonded. So, not for most of the fastest DSL plans.

The router supports 802.11 ac which means that the router can give a max speed of 1300 Mbps on the 5GHz channel and 300 on the 2.4GHz. [1]

Even if the real-world speed will be slower, the device is still compatible with Frontier FiOS if you would upgrade. 

The router is also more than enough for any DSL plan. 

The biggest con with this device is that it doesn’t support bonded ADSL or VDSL. So if you get it, make sure you don’t have either. 




#2 Actiontec C3000A (Best Performer)

  • Type: Modem/Router Combo
  • Modem Technology: ADSL/ADSL2+ (bonded), VDSL/VDSL2 (bonded) & Fiber
  • Recommended for speed: 940 Mbps or below
  • Wi-Fi Technology: 802.11 ac
  • Warranty: 90 days
  • Chosen as: Best Performer

If you don’t know what type of DSL you have and don’t want to ask Frontier, get the C3000A. 

This modem is compatible with nearly every DSL technology, from ADSL to bonded VDSL2. 

You might also have noticed that the modem is made for CenturyLink internet. But don’t worry, it will still work for Frontier.

The reason I recommend a CenturyLink modem is because there are few bonded DSL modems on the market. And of those few, the best ones are CenturyLink modems.

The router also supports Wi-Fi 5, or the 802.11 ac as it’s also called. This enables two types of networks, the 2.4GHz, and the 5GHz network. [2]

This is good because 2.4GHz has a better range while 5GHz is faster. Therefore, the router is compatible with Frontier FiOS (fiber). 

I should, however, note that the modem is a bit of an overkill if you have one of the slower Frontier DSL plans. That is if you don’t want to future-proof your Frontier compatible modem. 




#3 Arris NVG443B (Budget-Friendly)

  • Type: Modem/Router Combo
  • Modem Technology: ADSL/ADSL2+ (bonded), VDSL/VDSL2 (bonded)
  • Recommended for speed: 940 Mbps or below
  • Wi-Fi Technology: 802.11 ac
  • Warranty: 30 days
  • Chosen as: Budget-Friendly

The Arris NVG443B is a modem that Frontier usually rents, and thus, it works with basically any DSL internet.

This compatible modem might as well have been the value option since you get a lot of the money in this one.

The router supports Wi-Fi 5 or 802.11 ac, as it’s also called. This makes it dual-banded, which gives it a 2.4GHz and a 5GHz network. 

And like already said, the 2.4GHz network has a better range while the 5GHz network is faster.

This modem is the best option if you plan to bridge it and use a separate modem and router. 

Just note that this modem doesn’t have voice support, even though the Amazon page claims it does.

It’s the NV448B that has voice support, a modem which otherwise is the same as this one. [3]




What to Consider Before Buying a Frontier [FiOS] Approved Modem

Here is what you specifically should consider before buying a Frontier-approved modem for your internet. For a more general guide, check out the modem buying guide

Compatible with Frontier 

Buying a modem for your Frontier internet is not as easy as for cable providers. This is because DSL comes in many flavors with different technologies and speeds. 

And different modems are compatible with varying types of DSL. [4]

Therefore, you should contact Frontier before buying a modem and ask them what type of DSL your home has. That is if you don’t already know. 

You can consequently pick a modem from the list above that supports your type of DSL. 

If you don’t want to ask them, you can also guess based on your internet speed or get a modem that supports most DSL technologies. 

I should also note that you don’t need a modem if you have Frontier FiOS, but only a router. 

TypeMax Speed
ADSL8 Mbps
ADSL+20 Mbps
ADSL2+25 Mbps
Bonded ADSL2+40 Mbps
VDSL50 Mbps
VDSL2100 Mbps
Bonded VDSL2150 Mbps
Fiber940 Mbps

Modem/Router Combo or Separate

When buying a Frontier approved modem, you can either buy a modem/router combo (gateway) or separate devices. 

Modem/router combo being a modem and a router as one device while separate has them as two. 

But when you buy DSL modems, you will find that there are nearly only modem/router combos. 

The reason for this is that since DSL is slower, you don’t need that good of a router. 

This, however, doesn’t make it impossible to use a separate modem and router. 

Because you can put a gateway in something called bridge mode, which turns out the router in the device, allowing you to connect another router to it.

Although with Frontier DSL, I think a combo device will be enough for most. Even though I usually think that separate is better.

This is as long as you don’t have a large home that needs good coverage or need a specific feature on your router.

If you can’t decide, check out gateway vs. separate. There you can read about this topic in more depth.

Frontier FiOS (Fiber)

If you have Frontier FiOS, you don’t need a modem. Instead, Frontier provides you with an ONT for free that translates the fiber optic signals into digital signals. [5]

You will still need a router with Frontier FiOS. Which you can rent from Frontier for $10 a month or buy from a third-party source. 

You can also use the two first modem/router combos I have reviewed if you want, but I would not recommend it. Since you will pay for both a modem and a router but only use the router. 

I will write an article on what router is best for Frontier FiOS in the future. But for today, I recommend the TP-Link AX6000 for Frontier fiber.

Tp-Link AX6000 – Best Router For Frontier FiOS (Fiber)

Best For Fiber

  • Type: Wi-Fi Router
  • Max Speed: 5952 Mbps
  • Wi-Fi Technology: 802.11 ax
  • Warranty:  1 year

Rent Vs. Buying Frontier Equipment

Frontier charges $10 a month for you renting their equipment. This becomes $120 per year, which is more than enough to buy a new modem or router. 

Therefore, I’m a strong proponent of buying a third-party device. Not only is it cheaper in the long run, but it also enables enhanced performance. 

You should, however, take my opinions with a grain of salt because I do make a commission if you buy a modem.

FAQ

Here are some common question regarding Frontier and their internet equipment.

How do you install a Modem with Frontier?

  1. Pick a location with good airflow. So the device doesn’t overheat. 
  2. Connect the modem to the wall and the power cord. Additionally, connect the router with an ethernet cable if you are bridging the modem.
  3. The rest differs from modem to modem but follows the manual that comes with it. If you have more problems, you can always find more info on the manufacturer’s website. Also, you might need to contact Frontier to activate the modem. [6

Where do I ask Frontier about my DSL type?

You can either do it from their website, mail them at support@frontier.com, or call them at 855-981-4544

My Verdict

Buying a DSL modem is always a bit tricky. But I hope that with this article, you will choose one that will work for your internet. 

If you don’t have bonded DSL, I recommend the Netgear D6400-100NAS.

Because it’s a suitable value modem that will provide your home with a reliable internet connection.
