7 Best Routers For Comcast Xfinity

Below you can see overviews of the best routers for Xfinity. 

#1 TP-Link Archer AX50 – Editors Choice (Wi-Fi 6 Router)

  • Type: Wi-Fi 6 Router
  • Tested Max Speed: 690.52 Mbps
  • Recommended for: Blast! Pro or below (400Mbps)
  • Wireless Standard: Wi-Fi 6 (802.11ax)
  • Warranty: 2-years
  • Chosen as: Best Overall

The TP-Link Archer AX50 AX3000 is the router I recommend for you with the Blast! Pro plan (400 Mbps) or below. 

During testing, the router reached a speed of 690.52 Mbps from 5 feet on the 5GHz network. 

Other speeds I measured were 371.87 Mbps from 25 feet and 155.54 Mbps from 50 feet. Both on the 5Ghz network.

These speeds are excellent for the price and make for a perfect router for the Blast! Pro plan or below. You could even use it for the Extreme Pro plan (800 Mbps) if you find the slight loss in speed okay.

Range-wise, the router performed quite average, reaching around 90-100 feet. This is enough for a normal-sized home. 

The router also has good parental controls, which allow you to restrict what your kids can do on the internet and when they can use it. 

It also comes with a guest network and advanced QoS. Which allows priorities activities on your internet. 

The biggest con with the TP-Link AX50 is that it tends to overheat in warm climates. So, if your house often gets hot during summer, then I recommend another router.

If you have the Extreme Performance plan and want a traditional router. Then I consider the TP-Link AX6000 instead. 




#2 Netgear Orbi RBK852 – Best Performer (Mesh Wi-Fi)

  • Type: Mesh Wi-Fi
  • Tested Max Speed: 851.86 Mbps
  • Recommended for: Any Xfinity Plan
  • Wireless Standard: Wi-Fi 6 (802.11ax)
  • Warranty: 1-year
  • Chosen as: Best Performer (Mesh)

The Netgear Orbi RBR852 is a premium mesh system that I recommend for you with a large home that needs good coverage. 

During testing, the router reached 851.86 Mbps from 5 feet and 540.76 Mbps from 25 feet. 

These are two impressive results that are more than enough to watch multiple 4k movies.

What differentiates the Netgear Orbi RBR852 from most other mesh networks is its satellite. It’s nearly as fast as the router. 

With each satellite reaching 85-90% of the main router from each distance. This makes it enough for any Xfinity plan.

Overall the biggest drawback with the Netgear Orbi RBR852 is that it doesn’t support parental control or any QoS. 

So you can’t restrict your kid’s internet activities or priorities actives on the internet. 

Other than that, it’s by far the best for you looking for coverage and speed.




#3 TP-Link Deca M4 – Best Value (Mesh Wi-Fi)

  • Type: Mesh Wi-Fi
  • Tested Max Speed: 317.27 Mbps
  • Recommended for: Blast! Pro or Below (400 Mbps)
  • Wireless Standard: Wi-Fi 5 (802.11ac)
  • Warranty: 2 years
  • Chosen as: Best Value (Mesh)

If you need coverage and don’t want to pay a fortune, then the TP-Link Deca M4 is the perfect option for you. 

During testing, it managed to reach 317.27 Mbps on the 5GHz network from 5 feet. And 169.59 Mbps from 25 feet. 

This makes the router possible to use with the Blast! Pro plan. But in all honestly, it’s a better fit for the Performance Pro plan or below. 

The Deca M4 also supports both parental controls and advanced QoS. Making it possible for you to restrict your children’s actives on the internet and priorities data.

Its biggest drawback is how much speed the satellites lose, with a fallout of around 60-70% of the router’s speed. This makes the mesh network a bit slower than other alternatives. 

But as long as you don’t have a too-fast internet plan, the Deca M4 offers excellent coverage for a fair price.




#4 TP-Link Archer A7 – Budget-Friendly (Wi-Fi Router)

  • Type: Wi-Fi 5 Router
  • Tested Max Speed: 438.39 Mbps
  • Recommended for: Performance Select or below (100 Mbps)
  • Wireless Standard: Wi-Fi 5 (802.11ac)
  • Warranty: 2 years
  • Chosen as: Budget-Friendly

The TP-Link Archer A7 is the router I recommend for the Performance Select plan (100 Mbps) or below.

In the testing, the router reached 438.39 Mbps from 5 feet, 123.53 Mbps from 25 feet, and 57.31 Mbps from 50 feet on the 5GHz network.

And from 75 feet, using the 2.4GHz network, it reached 14.90 Mbps. 

This makes the router enough for the Performer Select plan and maybe even the Performance Pro plan. Depending on how much loss you accept. 

From a range perspective, the Archer A7 signal reached around 80-90 feet. This makes it enough for good coverage in a normal-sized home. 

The router also has parental controls, guest network, and QoS. Even though I found the QoS very underwhelming. As it only allowed to restrict bandwidth for particular devices and not for network actives. 

Overall, the TP-Link Archer A7 is one of the best budget routers I have tested.

Modem

Need a Xfinity Approved Modem?

If you don’t buy a modem/router combo, then you need a approved modem for your Xfinity router. Luckily we got you covered in the our article on the best modems for Xfinity.

#5 Motorola MG8702 – Best Value (Modem/Router Combo)

  • Type: Modem/Router Combo (Only for Cable internet)
  • Tested Max Speed: 518.51 Mbps
  • Recommended for: Blast! Pro or bellow (400 Mbps)
  • Wireless Standard: Wi-Fi 5 (802.11ac)
  • Warranty: 2 years
  • Chosen as: Best Value (Modem/Router Combo)

The Motorola MG8702 a the best modem/router combo for the Xfinity Blast! Pro plan (400 Mbps).

During testing, it reached 518.51 Mbps from 5 feet and 272.03 Mbps from 25 feet, both using the 5GHz network. 

You could even use it with the Extreme Pro plan. But then, you will not get a Wi-Fi speed of the 800 Mbps you pay for. 

The MG8702 also had a pretty good range, reaching about 80-90 feet. This should be enough for a normal-sized home as long as you place the device somewhere closer to the middle of the house. 

The cable modem is also DOCSIS 3.1, which is good since it will be compatible with Comcast Xfinity for a longer time.

Because Comcast is going to change out their DOCSIS 3.0 internet in the future. 

The biggest con with the device is its features. Both parental controls and QoS are somewhat lacking. 

With parental control, you can only block devices at certain times and not specific content online. 

And the QoS lacks the advanced controls which allow you to pick an activity to prioritize.

Other than that, it’s a solid option. 




#6 Netgear CAX80 – Premium Option (Modem/Router Combo)

  • Type: Modem/Router Combo (Only for Cable internet)
  • Tested Max Speed: 800+ Mbps
  • Recommended for: Any Xfinity Cable Plan
  • Wireless Standard: Wi-Fi 6 (802.11ax)
  • Warranty: 1 year
  • Chosen as: Premium Option (Modem/Router Combo)

The Netgear CAX80 is a suitable modem/router combo for any Comcast Xfinity Cable internet plan. 

Unfortunately, I wasn’t able to find its max speed. Since the house, I test the cable modems only have an 800 Mbps plan. 

But the router did max it out and managed to reach 800 Mbps from 5 feet. It also measured 583.15 Mbps from 25 feet and 298.47 Mbps from 50 feet. 

More than any other modem/router combo I have ever tried. 

The cable modem is also DOCSIS 3.1, and as already mentioned, this makes it future-proof.

The biggest drawback with the CAX80 is its lack of parental controls and advanced QoS. 

This makes it very hard to restrict your kid’s activities on the internet and prioritize data on your network. 




#7 Motorola MG7540 – Budget-Friendly (Modem/Router Combo)

  • Type: Modem/Router Combo (Only for Cable)
  • Tested Max Speed: 301.85 Mbps
  • Recommended for: Performance Pro or below (200 Mbps)
  • Wireless Standard: Wi-Fi 5 
  • Warranty: 2 years
  • Chosen as: Budget-Friendly (Modem/Router Combo)

The Motorola MG7540 is the best modem/router combo for the Performance Pro (200 Mbps) plan or below.

In the testing, it reached 301.85 Mbps from 5 feet and 102.38 Mbps from 25 feet. Both from the 5GHz network. 

Like many other, you can use this one for a better plan than I recommended. But you will lose some speed and not get all you pay for.

The cable modem is DOCSIS 3.0 with 16×4 channels. This means that the modem will work for now, but when Comcast Xfinity changes to DOCSIS 3.1 (we don’t know when), it will stop working. 

A drawback with this MG7540 is its limited range. During testing, it only had a range of about 70 feet.

Thus, I would avoid this device if you have a larger home with more than two floors. It fits best for average apartments. 

Another con is that the router, like the MG8702, is lacking in parental controls and QoS. 

This is a common thing on modem/router combos and is one of the reasons I recommend having separate devices. 




Things to Consider When Buying a Router for Comcast Xfinity

Here are some things you should specifically consider before buying a router for Comcast Xfinity. 

Device Speed

When you buy a router for Comcast Xfinity, one of the most important things is that the router’s real-world speed is as fast as your internet plan. 

Otherwise, the router will bottleneck your internet speed, and you won’t get the internet speed you are paying for. 

There are a couple of things that decide the device’s speed. Below you can learn more about them. 

Wi-Fi Standard

There is a lot to say about wireless standards and their respective speed. But I will go over the most important things here. 

As for now, there are two wireless standards in use. These are the IEEE 802.11ac (Wi-Fi 5) and IEEE 802.11ax (Wi-Fi 6).

The speeds of each standard depend on the router, its specs, and your distance from the router.

But below, you see the approximate max speed and real-world speed of each one. [1, 2]

Wi-Fi StandardMax SpeedMax Real-World SpeedRecommended With Xfinity Plan
Wi-Fi 5 (802.11ac)800-1800 Mbps100-600 MbpsUp to Performance Pro
Wi-Fi 6 (802.11ax)2000-10000 Mbps400-2000 MbpsUp to Gigabit Pro

As you see, it differs a lot from router to router. So how are you supposed to know?

Well, it’s here the router naming convention comes in. It’s a topic that deserves its article, but to explain it shortly: 

The best way to understand the naming convention is to look at an example. 

Let’s look at the budget option, the TP-Link Archer A7 AC1750. 

You see that the router name ends with AC1750. This is the router’s speed and wireless standard. 

AC, standing for Wi-Fi 5 and 1750 for the max speed of the bands combined with each other. 

This doesn’t mean that the router ever could reach 1750 Mbps, but rather that the 2.4GHz band has a max speed of 450 and the 5GHz band has a max speed of 1300 Mbps. These together add up to 1750 Mbps. [3]

But it doesn’t end here. Because the max speed is not the real-world speed.

In the example of the Archer A7, the max speed I reached during testing was 438.39 Mbps on the 5GHz network and 79.07 Mbps on the 2.4GHz network. 

Far from what the advertised max speed is.

The thing is that every router manufacturer does this. This is how they name the routers. 

Admittedly, a higher number will generally mean that the router is faster. But sometimes, a somewhat lower-numbered router will be faster than a higher number router. 

An example of this is the previously mentioned TP-Link Archer A7 AC1750 which beat the Netgear R7000 AC1900. 

Reaching 438.39 Mbps and 79.07 Mbps, compared to the R7000, which measured 254.63 Mbps and 54.59 Mbps. 

DOCSIS & Channels

If you buy a modem/router combo, you also must consider what DOCSIS version you need. 

For DOCSIS, you have two options, either DOCSIS 3.0 or 3.1. The difference is that 3.1 is newer and faster but more expensive, while 3.0 is slower but cheaper. 

For Xfinity, I recommend getting DOCSIS 3.1. Because even though 3.0 is enough for all cable internet plans for now. It won’t be in the future. 

DOCSIS 3.1 Benefits
  • Faster
  • Lower Latency
  • Future-proof
DOCSIS 3.0 Benefit
  • Cheaper

If you want to save some money, you can get a DOCSIS 3.0 device. Just be ready that you might have to upgrade it in a couple of years. 

You can learn more about the pros and cons of DOCSIS 3.1 and 3.0 here.

Bonding channels is something you need to consider if you decide to get a DOCSIS 3.0 cable modem. 

Channels look like Z×Y (16×4 as an example). And these determine the speed a DOCSIS 3.0 modem has. 

Below you can find a table with what channel bonding and DOCSIS version is compatible with what Xfinity internet Plan. [4]

Xfinity Internet PlanSpeed Connection TypeWi-Fi StandardDOCSIS Channel Bonding

Modem/Router Combo Vs. Separate Devices

If you have Xfinity cable internet, you can decide if you want a modem/router combo (gateway) or separate devices. 

With a gateway being a modem and a router as one device. While Separate has them as two.

Both options have their merits, but as a Network Engineer, I recommend separate devices. 

The reason for this is with separate devices, you can change one device if it breaks or needs an upgrade, rather than both. It also enables better performance and more customization. 

This is not to say that gateways are bad. They do often have a lower up-front cost and are generally easier to set up. 

Just don’t get a gateway if you have Xfinity fiber. Because fiber doesn’t use modems. It only needs a router. 

What about Mesh?

If you’re planning on getting a router, you have two options. Either a traditional router or what’s called a Mesh network. 

The difference between the two is that a Mesh network is a group of devices that creates a single Wi-Fi network.

And because it uses multiple devices, the network has better coverage than a single router. 

Mesh Benefit
  • Better coverage
Standard Router Benefits
  • Generally cheaper
  • Easier setup

In short, a Mesh system is suitable if you have a large home because of its good coverage. While a traditional router is enough for most other situations.

Compatible With Xfinity

For routers, compatibility with Xfinity is simple. Just make sure it’s a Wi-Fi router with a WAN port. 

For gateways (modem/router combos), it’s a bit harder. Because a modem needs to be Comcast Xfinity approved. To make sure the model works with your internet. 

Therefore, you can either pick any of the gateways recommended in this article. Or check out our article on Xfinity compatible modems

There you will find the best modem for Xfinity, a complete list of all Xfinity approved modems, and what to consider before buying a cable modem for Comcast. 

Extra Features

Here are some extra features you might want to have. 

QoS

QoS allows you to prioritize bandwidth between applications. This, for example, makes it possible for you to download a file and watch movies at the same time.

Because if you prioritize the movie, you can make sure it won’t stutter. 

Even though the file download will take a bit longer. 

Just note that you want an advanced QoS. This means that it does a lot of prioritization by itself or makes it very easy for you to use it. 

Parental controls

Parental controls allow you to control how much time and what your kids do on the internet. Having the ability to block objectionable material and URLs with the router.

As well as placing time constraints on you allow your kids to use the internet. 

Guest Network

Guest networks allow you to give visitors access to the internet without giving them access to all the other devices on your network. 

This increases your network’s security. Because your friends’ devices might have spyware or other viruses that otherwise can enter your network through their device unbeknownst to them.

Rent Vs. Buy Comcast Xfinity Router

Comcast’s equipment fee is $15 each month. This means that you need to pay $180 per year. [5]

If you do some math, you realize that buying your own devices will be much cheaper in the long run.

And it’s probably because of this you are reading this article. 

Many, however, still rent due to worrying about the setup and other problems. 

But you don’t have to worry. Modern network devices are generally easy to set up. 

And I have picked devices with extra simple setups that have good reputations for having few problems. 

Therefore, I advise everyone, stop renting equipment from Comcast and buy a third-party option. 

Even though I should note that I’m a bit biased. I do make a small commission if you buy a router.

Comcast Xfinity Internet Plans

Here are all Comcast Xfinity internet plans and what router, mesh network, and gateway works well with each internet plan.

Note, Gigabit and Gigabit Pro are fiber connections and thus don’t need a modem. Therefore, there is no gateway for them. 

FAQ

Here are some common questions about Comcast Xfinity and its equipment. 

What if I change ISP after purchasing a router & modem?

If you have a router, it’s usually nothing to worry about. Since most routers are compatible with most ISPs. 

For a modem, however, it’s a bit harder. Because you need to check if your current modem is on your new ISP’s approved modems list.

If it’s not, you need a new modem. If it is, you don’t.   

What’s the difference between router and modem?

A modem modulates the analog signal into a digital signal that your router and other devices can understand.

It also takes a digital signal from your router and changes it back into an analog signal that gets sent back to your ISP. 

The router is the device that gives your home Wi-Fi and creates your home network.

My Verdict

After countless hours of testing and researching, I have concluded that the TP-Link AX50 AX3000 is the best compatible router for Xfinity. 

Because it provides fast Wi-Fi 6 internet for a fair price with many useful features. Such as parenting controls and advanced QoS. 

That is unless you have the Extreme Pro plan or above. 

Then I recommend either the Netgear Orbi or the TP-Link AX6000
