The modem-router combos offer the most effective way of streamlining your home internet access through the use of one and not two clunky devices.

It’s worth noting that in as much as your rental modem might seem to work well, you will always incur high rental fees, and having two devices for internet access might not offer the best experience, which is why we recommend the modem-router combos. The combo unit allows you to maximize the power and the performance of your devices, and in some cases, you’d enjoy an expanded wireless coverage at high internet speeds.

The only catch is that choosing to buy the combo modem and router would make it a little more difficult for you to stay on top of the newest technologies, and upgrades would call for replacement of the entire unit. Other than this, you get to deal with a lot less clutter, great performance, and the best part is that buying one of the best modem-router combos means that you will have the best internet setup for your home.

So, which are the best modem-router combos on the market today?

Buying Guide for the Best Modem-Router Combos

Before you buy a modem-router combo, there are certain considerations that you need to keep in mind. These are features and functions that would affect the overall performance of the device you choose, and it will also set apart some of the modem-router combos from the others on the market. Some of the considerations that you need to keep in mind include:

  • The Supported Internet Speeds

One of the main considerations that you need to keep in mind in your search for the best modem-router combos is the speeds offered. First, you need to consider the plans offered by your service provider and the plans that you’d like to sign up for – this will be guided by your needs and lifestyle. With the ISP plans in mind, you can now begin your quest for the best modem-router combo, specifically, the one that will support the desired internet speeds.

Note that the speeds quoted for the router bit of the device are theoretical numbers, but the plan you subscribe to will determine whether you enjoy speeds close to what the router and the modem can support or not.

The highest internet speeds you get to enjoy will also be determined by your needs. For example, if you are a heavy gamer or if you stream HD content often, you might want to look out for the modem-router combo that supports the highest internet speeds for smooth, lag-free, and buffering-free gaming/ streaming experience.

  • Channel Bonding

For modems, one of the most important considerations that you need to keep in mind during your search is the modem’s channel bonding setup. Channel bonding is the feature that determines the speeds and the overall performance of the modem, and a modem with more bonded channels is one that offers the fastest internet speeds.

To understand how the channels influence the speed of the modem, you need to think of the channels as the total number of lanes on the highway. With more lanes, the highway is naturally able to move more cars through a specific area at the same time. In the case of the modems, the channels refer to the lanes through which digital information travels, in and out of your home.

To determine if the modem part of the router you are considering is fast or not, you need to look at the numbers for channel bonding. There always are two numbers, the downstream or download channels, which come fast, and the upload channels. In this case, you’d have a 32×8 modem, which translates to 32 download channels and 8 upload channels. These setups guide the speeds of the modem, and the example above offers the highest download and upload speeds.

Thanks to channel bonding, there is an aggregation of several downstream or upstream channels, hence the delivery of high speeds for your downloads and uploads.


DOCSIS or Data Over Cable Service Interface Specification refers to the international standard and a common feature in modems that allow for the easy addition of high-bandwidth data transfer systems to your existing coaxial cable TV system, hence the delivery of high internet speeds, with no need to replace the coaxial cable network. Keep in mind that in the ideal world, we’d all have access to Fiber home services, but the reality of this possibility is that it’s just too expensive, which means the need for a more practical solution.

DOCSIS is the practical solution here, as it allows users to choose their preferred DOCSIS standard, and consequently, the speed and performance of their cable internet connections.

The modem you choose today will be based on the DOCSIS 3.0 or DOCSIS 3.1 standard, and these numbers show the advancement levels in DOCSIS protocols and the fact that you now get to enjoy very high internet speeds compared to the people who used modems running on the older DOCSIS protocols.

That said, it’s worth noting that DOCSIS works via its two main components – the MAC Layer for media access control, and the PHY layer, which denotes the physical layer that has everything to do with cable and wire routing, and also the data transmission frequency, hence fast speeds inferring better or the best performance. The MAC layer constitutes the design of the DOCSIS system for the modem but in relation to the intelligent setup of the equipment and, in consequence, the ability of this system to handle massive amounts of information processed at any given time, with a few ‘traffic jams’ as possible. By working together, these two layers of DOCSIS ensure high-speed connectivity and the best performance of your modem.

Now that you know what DOCSIS is, you’ll be happy to note that the DOCSIS 3.1 modems are faster and more robust than the DOCSIS 3.0, but even the DOCSIS 3.0 modems still offer the best performance.

  • WiFi Performance

The other thing that you should be looking at as you look for the best modem-router combo is that WiFi performance of the device. The good news is that you can tell more about the wireless performance of the modem-router combo by looking at the specifications of the device, specifically, the wireless protocol and the number of radio bands. The best modem-router combos have routers set on the high-performance 802.11ac standard, which offers high internet speeds, and they often dual-band units with reliable 2.4GHz and 5GHz bands.

The difference between the 2.4GHz band and the 5GHz band is that while the 2.4GHz band offers a long-range coverage, it offers slow internet speeds, even as the 5GHz band offers a shorter range, but at higher speeds. There also are differences in the number of channels for the two bands – there are11 channels for the 2.4GHz band and 23 channels for the 5GHz bands.

Note that the 802.11ac protocol also amplifies the range and the coverage of the radio bands.

  • Ports

You also need to look out for the modem-router combos that feature a good number of Ethernet ports for easy connection to your devices, allowing you to enjoy fast internet connection. Also, look for a device with USB ports.

  • Coverage and Range

The other important consideration to keep in mind is the coverage of the device, and whether the range it offers is adequate for your needs. Besides the stated specifications, you also need to look out for features like additional external antennas with support for beamforming and MU-MIMO, among other technological features.


Is there a reason why I shouldn’t buy the modem-router combo?

Although the combo setup saves you some money and you won’t have to deal with a big wiring mess, the combo unit makes it harder for upgrades because you’d have to upgrade each unit individually, and this costs more.

Which is the right modem for fiber optic internet?

Unlike your cable modem, the fiber optic internet systems do not use modems, but they use the optical network terminals (ONTs) instead. The technology used by the ONTs is different, even though it works much like the cable systems. The other thing to keep in mind is that there are limited third-party ONTs, and you’d have to lease it from your ISP.

Is WiFi speed affected by the modem-router combo setup?

Yes. The modem affects the overall WiFi speeds for your device, and this often happens because of the splitting of channels/ signals from your modem to the router, and there is also further splitting from the use of the network signals by multiple devices.


The best modem-router combo units are compatible with most ISPs, and they come with features that allow you to meet most of your basic internet needs by only investing in one device and also saving money otherwise spent on modem rental. These combo units mean that you wouldn’t have to worry about the configuration complexities that come from having two separate devices, and with everything in one place, you can enjoy seamless connectivity. The modem-router combos reviewed here are some of the best options on the market today, and you can get any of them depending on your needs.
