Should you get a cable modem and router combo?
With cable internet, a modem is your connection to the network, and a router makes that connection wireless (or Wi-Fi). If you get these devices separately, staying on top of the newest technology is easier. But there’s a lot less clutter to deal with when you get them in one device.
Many ISPs will offer you the convenience of a cable modem and router combo for a monthly fee. But if you want to save money (and space), buying your own device will pay off in the long run.

Top cable modem and routers
Pros
- Future-proofed for longevity
- Backward compatible to work with old technology
Cons
- A pricy splurge
When you’re on the prowl for the sleekest modem/router combo out there, check out this fine piece of plastic-encased technology. Featuring a red racing stripe and four antennas, NETGEAR did its best to show that this router is as fast and advanced as possible.
But with the high price tag, don’t go for this one unless you have gigabit internet or plan to have it soon. As far as we can tell, it’s the only router and modem combo out there that has DOCSIS 3.1 technology, so choose this one if you want the newest tech in a neat package to go with your blazing internet.
Pros
- Affordable high speed
- 3 years of included McAfee protection
Cons
- Not future-proof
This ARRIS SURFboard doesn’t have fancy DOCSIS 3.1 technology like the NETGEAR Nighthawk C7800, but it will still support most cable internet speed—and at half the cost. ARRIS sweetens the deal with McAfee Secure Whole Home Internet so you don’t have to stress about viruses.
Just because you’re shelling out for fast internet doesn’t mean you have to empty your pockets for a modem/router too. Think of this as a cheaper gig solution that might not be relevant forever but will certainly last long enough to save you from leasing a device from your ISP.
Pros
- Parental controls
- Cool style for a sleek desktop look
Cons
- Less likely to get Amazon Prime discounts
Like most NETGEAR Nighthawks, the C7000 is a slick piece of machinery. Thanks to its 24 download channels, it runs smooth and fast for all your streaming and gaming needs. And that textured grate on the exterior adds an extra bit of panache.
Grab this combo box to get up to 400 Mbps of unhindered internet access—and look cool while doing it.
Pros
- Affordable high speed
- McAfee Secure Whole Home Internet
Cons
- Not future proof
This Motorola model is an excellent choice for speeds up to 300 Mbps. Unless there’s a major sale going on, it’s usually more affordable than the other options above. The only drawback is that it doesn’t have a USB port, which is a bummer if you need to connect a printer or add extra storage.
Go for this modem if you have the matching speed with your internet plan and don’t have a ton of devices running at once. While sixteen download channels should be enough for most households, you may want to go for something stronger if you’re trying to run an entire smart home on it.
Pros
- Good for covering the basics
- A killer deal for what you get
Cons
- Old technology that might require replacement in a few years
If you want to get some incredible savings on the best cable modem and router combos versus your provider’s lease option, the MOTOROLA MG7315 is the way to go. It supports only lower cable speeds and the technology is a little behind the times, but it’s still kicking.
This device is the best choice for someone who wants to save, doesn’t have many devices, and has an internet plan with download speeds lower than 145 Mbps. And since this baby pays for itself in less than a year, it’s a good option when you’re just trying out owning your own modem/router.
What to look for in a cable modem and router combo
If you’re looking for the best cable modem router combo, it’s probably because you like to simplify. You don’t want two devices when one will do the job. So, why complicate the process with tons of garbled numbers and letters?
We get you. It’s time to demystify all the tech specs.
Supported internet speeds
When you sign up for internet with your provider, you’ll choose a plan with download speeds that fit your usage style. Buy a cable modem and router combo that can support those speeds, or you won’t be able to enjoy all the speeds you’re paying for.
Not sure how much speed you need? Our buddies over at HighSpeedInternet.com have a tool to help you calculate your ideal internet speed. It takes only a couple of minutes, so we recommend giving it a try.
Pro Tip: Sending internet over Wi-Fi can degrade your connection. If you want to enjoy smooth wireless streaming and gaming, it’s safest to go for an internet plan that has higher speeds than you think you need.
Channel bonding on modems
More modem channels mean faster internet. Think of them as lanes on a highway. More lanes mean you can move more cars through an area at the same time. Channels are lanes for information to travel into and out of your home.
The naming convention lists download channels first, then upload. For instance, 16×4 means you have sixteen channels dedicated to downloading and four to uploading. With that setup, you can easily reach download speeds of 300 Mbps.
Pro Tip: More channels equal more speed, but it can’t help you access more speed than you’re already paying for with your ISP. You don’t want to pay for more modem than you need. Follow our recommendations by speed above for your best fit.

Wi-Fi performance
Specs on Wi-Fi performance are one part useful information and one part marketing gibberish.
The useful part
The letters matter: they represent what generation of wireless technology the router uses. The ones in this article were “AC” from “802.11ac,” and “N” from “802.11n.” These standards were popularized in 2012 and 2009 respectively.
Both of these types are dual-band, which means they support Wi-Fi connections on 2.4 GHz and 5.0 GHz frequencies. Yeah, more numbers—sorry.
Long story short, routers used to work only on a 2.4 GHz frequency, which can slip through the walls of your home and work from a long distance. The problem is that it has just 11 channels, and the connection isn’t as strong.
Then 5.0 GHz came along. It has 23 channels, which gives it a superfast connection. Initially, it didn’t have the same range as 2.4 GHz, but 802.11ac tech amplifies the reach of both to about 820 feet. With an 802.11n router, 2.4 GHz will still reach 820 feet, but 5.0 GHz reaches just 460 feet.
You can take advantage of this newfound knowledge by connecting your internet-ready devices to the frequency that will best support them.
| Devices suited to 2.4 GHz | Devices suited to 5.0 GHz |
|---|---|
●Security equipment ●Devices separated from the router by many walls ●Devices in distant parts of your home | ●Smart TVs ●Computers ●Gaming consoles ●Tablets and smartphones |
When you’re connecting your devices, both frequencies will have your router name, but the 5.0 GHz network will usually have 5G as part of the title.
The marketing gibberish
While the letters in Wi-Fi performance show off the technology your router uses, the numbers are there to be big and make you think one router is better than another. They represent theoretically how much data your router could transfer per second if it were using its max number of channels.
For example, an AC1900 router’s maximum bandwidth would be 1,900 Mbps. But it won’t ever reach those speeds outside an optimized laboratory.
Out in the real world, there’s no notable difference in performance between AC1750 and AC1900. A router with AC1000 and below has only single-band technology (one 2.4 GHz frequency, no 5.0), so it probably won’t keep up with a high-tech home. Otherwise, don’t worry about these big ole numbers.
Final take
Choosing a router and modem combo is super easy once you know what to look for. Support the speeds you need, follow the good reviews, and select a style you like. That’s it. It’s a clear-cut process perfectly matched to this simplified, two-in-one device.
Cable modem/router Frequently Asked Questions
Is there a modem and router in one?
There are many models of modems and routers combined in one device. You might see this called a modem router or a gateway. Be sure to get one that can support the speed of your internet plan.
Are there any disadvantages to getting a modem and router combo?
While it’s nice to have two devices in one, having a separate modem and router makes it easier to keep up with leaps in technology because you can upgrade them individually. For example, smart routers are making waves right now, but they’re not available in a combo yet. And the newest modem tech, DOCSIS 3.1, isn’t widely available in combos either.
Do I need a special modem for fiber-optic internet?
Unlike cable, fiber internet doesn’t use modems—it uses optical network terminals (ONTs). The technology is different, but it serves the same purpose. Unfortunately, it’s hard to find a third-party ONT, so you’ll most likely have to lease the one your fiber ISP (Internet Service Provider) offers.
