Fiber Optic connections don’t require a modem. They work with ONT (Optical Network Terminal). Internet providers provide the ONT device during installation, and all you need is a high-speed router that can handle fiber internet.

However, if you don’t want to invest in a high-end router, you can opt for a fiber modem/router, which is an easy-to-use gateway. Keep in mind that it won’t be as powerful as a traditional router. Anyway, which one should you choose?

Well, finding the right device can be challenging due to limited options, technical jargon, and ISP compatibility issues. To help with this, I tested 9 gateways that support fiber internet and finalized my top 5 picks for 2024.

An ideal fiber modem includes multiple networking modes, good speeds, a handful of Ethernet slots, and capable hardware. Considering these factors, this list is handpicked to suit diverse user requirements and internet providers.

Important Note:

 Check for compatibility with your service provider. The list comprises the top 5 wireless gateways that work with the likes of Verizon FiOS and CenturyLink.

1. Best Overall: Verizon FiOS CR1000A

Making its place at the top, FiOS CR1000A is one of the best gateways available. It brings WiFi 6E and Tri-Band — a solid combination for high-speed internet.

The two 10G and two 2.5 Ethernet ports, each support top-tier performance. But it’s only compatible with Verizon FiOS. Besides, compared to its predecessor, it brings multiple upgrades, and many were a surprise for me.

Speeds & Performance

The CR1000A brings the new 6 GHz band and tri-band setup in routing. Although its theoretical throughput cap isn’t revealed yet, it’s said to support Gigabit+ speeds. This is why I got the Verizon 1 Gbps plan to test it out, and here are the results:

To start with, I placed my test device, or Dell XPS laptop, stationed 20 feet away from the gateway and managed speeds of up to 861 Mbps and 664 Mbps, respectively, for downloads and uploads.

Verizon FiOS CR1000A Speed Test

Meanwhile, 40 feet away, I got respective speeds of up to 427 Mbps and 265 Mbps.

The speed drops were a bit concerning, but I could stream any movies, videos, or other content in 4K and attend HD Zoom video calls without a bit faltering in quality. 

WiFi Coverage & Devices Capacity

The FiOS CR1000A, with its highly amplified antennas, claims to cover up a space of up to 2,000 Sq Ft, which is great compared to other fiber-optic gateways available.

To put its penetration ability to a test, I installed it at my grandpa’s 100-year-old house with thick walls. And it managed to encase the entire 1,500 Sq Ft space with signals.

The antennas further work in tandem with MU-MIMO tech to handle up to 30 devices, and the numbers maxed out at 24 in my test. These are inclusive of my bandwidth-hogging devices like laptops, computers, smartphones, and others.

Ports & Design

You’ll find two 10G LAN/WANs and two 2.5 LANs alongside a MoCA 2.5G port to support multi-gig plans. I got a 2 Gbps plan, established a wired connection with the 10G port, and got a maximum download speed of 1.96 Gbps and upload speed of 1.74 Gbps.

Besides, the best part is the gaming performance it delivers, as I could play Overwatch at a faster 5ms ping and 103 FPS with video streams running in the background.

Verizon upgraded the design from G3100, as you see a clean rectangular build with dimensions of 10 x 6 x 6 inches. Less footprint means your desk has space to accommodate other things.


The manufacturer hasn’t revealed much about its processing setup but telling by the performance, it’s indeed beastly. The processor with 2GB RAM and 4GB flash memory never stops you from installing firmware or compromising your gaming performance.

The latency is appropriately low, courtesy of the interference-immune hardware.


Verizon FiOS CR1000A has everything one expects from a high-end fiber-supported modem. Its speeds are impressive, it can cover a lot of space with signals, and its multi-gig ports are there for your high-end gaming or streaming connections. But its premium cost is what makes it untouchable for many users.

  • WiFi Range: Up to 2,000 Sq Ft
  • Ports: 4 x 1G + 1 x 1G WAN + 1 x MoCA 2.5 + 1 x USB 3.0

The G3100 is yet another fiber gateway from Verizon FiOS. It brings the Wi-Fi 6 and Tri-Band for a fast and reliable wireless connection. Next is FTTP technology, which allows you to maximize internet speeds without losing packets.

And compared to the G1100, it promises almost 2x better coverage. Let’s find out if it’s worth your attention!

Speeds & Performance

The G3100 entails a tri-band Wi-Fi 6 setup for you to pair up speeds over 1 Gbps. I got the FiOS 1 Gbps plan and my MacBook Pro 16″ to record speeds at various distances.

The gateway clocked download speeds of 709 Mbps and upload speeds of 554 Mbps at 20 feet.

Verizon FiOS G3100 Speed Test

Farther away at 40 feet, the speeds are still very good, measuring 378 Mbps and 271 Mbps, respectively, for downloads and uploads.

The speeds, however, are a bit lower than my previous pick, but the performance it delivers ensures you and your family have no issues playing online games, streaming 4K content, and doing some heavy browsing.

WiFi Coverage & Devices Capacity

A big part of any router or gateway’s performance is its range, which measures how a connection is affected by distance or objects. With a stipulated range of 2,000 Sq Ft, the G3100 stays just identical to my top recommendation, which is good. The maximum distance I could access the signal was around 1,500-1,600 Sq Ft.

But, it disappoints a tad when it comes to the connection handling capacity. Despite entailing MU-MIMO, the gateway only allows 20-30 devices to connect at a time. That’s still decent for any family of four to five people residing in a mid-sized house.

Things To Consider

Now that you know which fiber optic modem or gateway to pick, here is a detailed guide to analyzing the attributes better:

Understand Your Requirements

The first question that comes to mind while picking a fiber-ready modem setup is the need for it. For instance, are you planning to pick one for your standard home use or intensive loads like gaming?

Or, are you looking to get one for the office or to establish a network in any commercial space? Depending on user requirements, you purchase the networking device.

Like if you want something for your small home, the Arris NVG468MQ might be a good bet. However, the C4000XG from Greenwave is one of the top modems for gamers, courtesy of the QoS support.

Compatibility with your ISP

ISP compatibility is the most important aspect to look at before spending your hard-earned money on modems that work with fiber connections.

Most gateway devices aren’t compatible with every ISP in the market. For instance, the powerful C4000XG works with CenturyLink, whereas the Arris NVG468MQ complements Frontier and Verizon FiOS.

Therefore, before investing, check out the ISP compatibility and pick only the one that makes sense to the area-specific service provider. And it is always better to pick one that covers most of the ISPs so you can move around and the device stays relevant.

Relevant Ports & Connectivity

If you have multiple bandwidth-hungry devices at home or office, including the Smart TV, PS4 or PS5, and more, I would recommend considering a device like the C4000XG, which offers multiple Ethernet ports, 5 to be exact.

However, if you want to pair an extender to the modem-router combo or standardize the usage, it is better to go for a device with one to two ports. That way, you can save some money as well.

Hardware & Design

A multi-core processor is a nice addition to any networking setup. Yet, you must keep your eyes open for at least 256MB of RAM. Networking devices as powerful as those used for large offices might even have a multi-core processor with 512MB of RAM.

Next, you have the design, which might be an important parameter to consider while investing in a new fiber-supported modem. If you often change your workplace, it is advisable to get something light.

However, if you plan on keeping the device fixed at home or office, you might need to prioritize heat dissipation and durable aesthetics over anything else.

Special Features

If you are into additional features and more detailed evaluations, check for QoS functionality, USB ports for sharing data over the network, antennas relevant to the modem-router setup, etc. Depending on the availability of these specifications or lack thereof, the final price of the fiber-supported gateway device is determined.

Frequently Asked Questions

Do you need a special modem for fiber internet?

You don’t need a modem for fiber internet. You need a wireless gateway, also known as a modem router combo. However, fiber optic gateways differ from the traditional router modem combos used for cable ISPs. So, you must check compatibility with your fiber provider before purchasing a device.

How do I connect my gateway to a fiber connection?

Every fiber connection setup runs down to your home or the nearest hub right into the ONT or Optical Network Terminal. The optical fiber from the hub is then fed into the PON port of the concerned modem, which is usually color-coded as blue or green.

What is the best gateway for fiber internet?

Many contenders for the best fiber optic gateway tag in the retail space exist. However, a good way to identify one is to look for price-to-value balance, ease of setting up, app-based support, and a higher number of ethernet ports.


Each of these five fiber internet gateways lets you cater to specific user requirements. And despite this being a short list, if you are still confused, here are the use-case-specific segregation to help you choose:

  • If speed and number of ports are your primary concern, FiOS CR1000A for Verizon FiOS is a perfect choice.
  • If you also want to keep doors open to DSL, the ZyXEL C3000Z is the one to choose.
  • Finally, if you want something budget-friendly but without compromising on features, the ARRIS NVG468MQ seems like the device to go for.

Yet, you can always look at some of the other picks and get the suitable device that aligns with your requirements, needs, and budget.
