Signing up for Comcast’s Xfinity internet service presents you with two options: either rent a router for Xfinity or purchase your own. At first, it might seem smarter to go with the path of least resistance and get the Xfinity router; it’s going to work and is presented as pretty affordable per month. However, after doing a cost-benefit analysis, buying your own modem and router will be cheaper, especially if you’re going to be an Xfinity customer for many years. Router shopping can be costly and nerve-wracking, especially if you purchase the incorrect router and there’s a strict no-return policy. Leave the frantic searching to us: we’ve come up with this list of the best routers for Xfinity.

How we chose the best routers for Xfinity

First, you need to identify what kind of router you want. Then, you need to verify that the router works with Xfinity. To come up with this list, we researched the wide diversity of manufacturer claims, model specs, peer experiences, and user impressions. We then made our top five picks.

And, it meets DOCSIS 3.1 specifications. It’s worth noting that it will take some time to see a return on your investment with the Nighthawk, but multiple reviews note that owners’ internet speed and performance were improved after setup, making the purchase worth it. There’s a reason Netgear routers are consistently among our favorites.

What to consider when buying the best routers for Xfinity

Reviews, meeting at least the minimum requirements, and crowd-sourced reports can tell you a lot about the overall functioning of a router. Then smaller factors can help you pick once you’ve narrowed it down to a few choices.

Should I get a modem-router combo?

A modem connects you to the internet that Xfinity provides. A router lets your devices access the internet from around your house. A router serves little to no purpose without a modem. If you get a router but don’t have a modem, you will be stuck with a box offering you access, but access that’s the equivalent of opening a door and finding a brick wall.

This is why some reach for a modem-router combo: you get everything you need in a single piece of equipment. To avoid disappointment, be sure to check for compatibility, either from the manufacturer or from Xfinity’s website.


Routers are rated on the max speed they can deliver. Find the perfect internet speed for you, then buy a router that has a max speed above but not too above that speed (why pay for something you’re not using, after all). 

The next thing you’ll need to consider is DOCSIS, or “Data Over Cable Services Interface Specification.” This factor affects your speed by determining how well the internet can travel from the modem part of the combo to the router part.

There are two varieties of DOCSIS you’ll have to worry about: DOCSIS 3.0 and DOCSIS 3.1. DOCSIS 3.0 is capable of 200 Mbps upload speeds and up to 1 Gbps download speeds. DOCSIS 3.1 has 2 Gbps upload and 10 Gbps download speeds. 

WiFi standard

There are three WiFi standards you are likely to hear about while router shopping. From most to least common, they are WiFi 5, WiFi 6, and WiFi 6E. 

WiFi 5: This standard appears on most routers, and supports speeds up to 3.5 Gbps. It was first introduced around 2011.  

WiFi 6: We’ve written extensively about WiFi 6, but to sum up: WiFi 6 began in 2019 and can handle multi-gigabit internet speeds. It can also handle a much larger number of network devices at once, including smart light switches and smart speakers. WiFi 6 routers also have next-gen. security protocols, like WPA3, and an extended range.

WiFi 6E: WiFi 6E is newer than WiFi 6, with the E standing for “Enhanced.” Understanding WiFi 6E is important for future-proofing devices. If you want something to last for years, one of our picks for the best WiFi 6 routers should be more than enough.


WiFi range is determined by the kind of router you’re using, the wireless protocol the router follows, and the space you’re in. 2.4 GHz WiFi routers can reach up to 150 feet indoors and 300 feet outdoors and should be used if you’re looking for long-distance WiFi. Routers running on 5 GHz bands can reach around one-third of these distances since it uses narrower wavelengths—because of this, you should choose a 5 GHz router for speed, but only if your devices can be located nearer to your internet access point. Newer routers operate on both 2.4 GHz and 5 GHz bands to reach greater distances and achieve maximum throughput for devices in closer proximity. 

Walls, electronic devices, and certain other materials in between your device and the router can weaken the signal (which is why we’ve put together a handy guide to WiFi extenders). 


Q: How much does a router cost?

It depends on what kind of router you purchase. Router-modem combos can cost between $100-$300. A router by itself can cost as low as $50, depending on which one you purchase. And extra capabilities—like MU-MIMO, QoS, and VPN points—can up the price of a router. 

Q: What’s the difference between router and modem?

We’ve used this example before and we’re happy to use it again: The modem is the entire pie that Xfinity has baked, connecting you to all the internet that the company provides. Well, at least the slice of Xfinity’s pie you pay for. Your plan determines how large your slice is. The only way you can access that slice of pie is through a modem. Connecting a router to the modem lets you give bites of the pie you’ve bought to your phone, laptop, gaming console, and/or smart devices. A router will not serve many purposes without a modem.

Q: How long do routers last?

Between advances and technology and overall lifecycles, a router will last about five years. Some even say you should replace it every three to four years. Of course, routers that include newer WiFi protocols will tend to lean on the five-year mark since they’re built to be future-proof. If you notice that your WiFi range, speed, and connection are getting worse, it might be time for an upgrade. 

Final thoughts on the best routers for Xfinity

The best routers for Xfinity should accommodate your current internet plan but leave room to level up for faster internet speeds. VPN capabilities, Alexa compatibility, and app customization are a few add-ons that help you integrate other technologies into one device. At the end of the day, the best Xfinity router should make your life easier and worry-free from spotty internet.

Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now.

Our writers and editors have combined decades of experience covering and reviewing consumer electronics. We each have our own obsessive specialties—from high-end audio to video games to cameras and beyond—but when we’re reviewing devices outside of our immediate wheelhouses, we do our best to seek out trustworthy voices and opinions to help guide people to the very best recommendations. We know we don’t know everything, but we’re excited to live through the analysis paralysis that internet shopping can spur so readers don’t have to.
