WiFi Modem Router For Comcast

Best Router For Comcast Xfinity & Modem Router Combo (September 2017)

Many subscribers’ to Comcast Xfinity don’t realize that they have the option to buy their own best router for Comcast. You may have received a wireless router as well as other internet equipment from Comcast Xfinity when you first started subscribing to their service, but what you probably didn’t realize is that those small monthly rental fees slowly add up.

Every month you lose around $10 or more by paying rental fees. That's $120/year.

It may just start off by paying just a few dollars a month – and nobody thinks twice about $5 a month for the convenience of having everything taken care for you. But when the rates get bumped up, slowly but surely, that’s when you need to wake up and see that your pockets are getting lighter, while Comcast’s pockets are definitely getting much heavier.

In fact, did you know that Comcast (as well as other major ISPs) make a lot of their revenue through rentals?

How do you even know if you’re getting the best router for Comcast Xfinity when you rent your internet equipment from them? The fact is, many people don’t. And by the time most users have wizened up, a huge chunk of money would have found their way to Comcast. This is when they decide to purchase their own best router for Comcast.

Here is the list of the 5 best wireless routers and 5 modem router combos for Comcast Xfinity that we have tested for 2 weeks and highly recommend. And if you want a modem to go with any of these routers, check out our list of Comcast approved modems.

Modem Router Combo vs Wireless Router For Comcast Xfinity

Even though there are many advantages to owning a modem router combo, there are equally compelling reasons to why you should buy a separate router for Comcast Xfinity.

Netgear R7000 back side - Comcast Xfinity Router

Reasons why you should get a modem router combo for Comcast:

  • A modem router combo is a good deal, as you will be getting two products in one neat package, cutting back on doing extra research and additional shopping around.
  • Easier set up, as you have to deal with only one device
  • More cost effective, as buying separate devices may make your pockets a little lighter

Reasons why you should buy your own best router for Comcast

  • You can tweak your own settings to get exactly what you need from your router which you may be unable to do with a combined unit
  • You are not absolutely disconnected from the internet should something go wrong. It is cheaper to replace either a modem or a router rather than a whole modem-router combo. You can even just pop into a store for a quick purchase just to be connected. But if your modem router combo goes bust, you could be stranded in an internet less world. *perish the thought*
  • You tend to have better specifications. In the end, performance is what matters.

What Do You Expect From Your Comcast Wireless Router

When you are shopping for a router or a modem router combo for Comcast, you need to be sure it is compatible with Comcast. Fortunately, all of the mentioned devices in this guide are all compatible. So, that’s one point out of the way.

Each individual has different internet needs. If one person needs a high performance unit will not appreciate a router that will cover huge spaces, especially if they live in a small apartment complex. One who is looking for high performance will not look at models which are low budgets. But this is why the bluegadgettooth team has looked around, researched and reviewed many routers/ modem router combos so that you find something that suits your requirements.

In the end, the routers function very well as separate devices as they can be tweaked to fit your exact needs, while a modem router combo is perfect for those who want to get set up without too much hassle. In either case, there’s something for everyone.

3 Reasons Why You Shouldn’t Rent a Router from Comcast Xfinity

Best Router For Comcast

Simply because you’re smarter than that. Jokes aside, these are the reasons why your SHOULD buy your own best router for Comcast Xfinity instead of renting the gadget from them.

1. You can say goodbye to any rental fees

Either these fees will be hidden, or you’ll see the monthly fee written in small text as ‘equipment rental fee’. Why should you continuously [ay for something that is not top-of-the-line? If you decide to buy your own wireless router for Xfinity, your purchase will quickly pay for itself within a short time.

2. Enjoy faster file transfers and allow multiple users to stream videos simultaneously

We all have family and friends who may just pop over for the weekend, and you can’t tell them not to connect to your Wifi. But your old router may not be able to handle the number of connections and this may affect your speeds to the various connected devices.

3. Because you want to enjoy less interference

Newer wireless routers have been designed keeping the 21st century user in mind. You have better things to do with your time than figuring how to optimize your router’s performance. But getting a newer model (which, trust us, your ISP will not give you as part of your rental plan) will allow you to just sit back, let the router use its own intelligence to handle the load balancing.

4. Just because we need to mention this, so you get a bonus point

Comcast makes its money back on the routers it rents to its users within a short while, and everything after is pure profit. So, you’re actually paying Comcast to use an old gadget which may be on the verge of obsolescence. Why would you want to do that? We would just say, buy your own, and throw yourself a party.

1. Linksys AC1900 Dual Band Wireless Router

Best Router For Comcast Xfinity Overall (Editor's Choice)

Thanks to its slick design, it is not an eyesore anywhere, despite its size. This wireless router for Comcast has a great range with fantastic wireless performance. It comes equipped with a power switch which makes network cycling a lot easier when errors occur.

The setup is quite simple, almost automatic and requires no special knowledge. The ease of the installation appeals to any “first-time” home network customer. Once you plug it into your computer and type in the router's web address, the simplicity of the setup begins. There is an ease in this process with the simple directions.

2. Netgear Nighthawk AC1750 Dual Band WiFi Router R6700

Best Low Budget Wireless Router For Comcast Xfinity

Not all homes are alike and understanding that each person’s living space, budget and internet needs is unique lead Netgear to create the R6700. Many of us don’t want to shell out big bucks to be connected, and its good news that Netgear released a low budget option for those who want the best router for Comcast without going broke, while getting a product that is part of the Nighthawk series.


The design looks fairly sturdy and we appreciated the rubber feet which supported the wide base – now you don’t have to worry about the router sliding off any surface anytime soon. If space is a crunch for you – you do have the option to wall mount, it’s little details like this that make the Nighthawk series true gems in the internet field.

This large sized router released by Netgear proves to be a power house for getting your devices connected. When we tested this one out, we were thinking, yeah- budget option, it should have certain limitations and honestly weren’t expecting much. Almost identical to the R7000 model, we loved the longer and thicker external antennas which proved to be an asset to the router as you can remove them or adjust them to get the best results possible.

The Netgear Genie App also made life a lot easier as we didn’t have to hang around the router to make any changes. From setting up parental controls so our little ones could access certain sites, to monitoring and managing our network, the app is a good feature of the Netgear Nighthawk.

Enough of the small talk. When it comes to storage performance of the 3.0 USB port, the R6700 does shine, beating performances of other tested routers. The range is great, with my devices being connected with good signal strength even in my back garden or in the garage, which has many obstacles between the client and the router. The range this router delivers is amazing!

For people who can get muddled up with installation and set up processes will love the R6700 which has a simple set up that will get your wireless network up and running before you even know it.

Overall, it may not be the best wireless router out there, but for the great price, it provides excellent 5GHz speeds and does still outperform many routers in its class. A great money saver!


Being 802.11AC, the R6700 is still considered to be one of the best routers for Comcast as its 5GHz speeds still delivers. This router has a 1GHz dual core processor and with speeds theoretically (as of now) slated to reach 1750Mbps (with 1300Mbps on AC and 450Mbps on the N), you know you could get decent speeds – but this also depends on your plan with your ISP. The beamforming feature did make a difference as well – the R6700 delivered speeds reaching 82 Mbps, on a connection that was supposed to deliver 75Mbps. Pretty good news, we think!


Gamers can be happy as the R6700 has advanced QoS and the dual core processor which boosts both wireless and wired performance. People in larger homes can benefit from this well priced router as well. Another plus point in its favour is the boosted speeds for mobile devices.

Netgear Nighthawk R6700 Pros

  • Boosted wireless and wired speeds due to dual core processor
  • Great range
  • Beamforming feature for better whole home coverage
  • Great parental controls
  • Super value for money

Netgear Nighthawk R6700 Cons

  • Not the best router in the market (but you have to be prepared to pay a lot more for those)

3. Google WiFi Router - OnHub AC1900

Best Router For Large Homes

Google is a name that is synonymous with cutting edge technology and although it is not new to the world of hardware, it has successfully made a foray into an otherwise dominated world of internet gear. It’s conquered the Search engine world, and this venture to combine the smart software it develops with the gear we access it on has led them to introduce the Google Wifi Router.

How much simpler can this be? You are on the lookout for a great wifi router, and you come across this aptly named ‘Wifi router’ by Google. There is a reason, well many reasons, why Google’s Wifi Router is one of the best routers for Comcast.


Made to sit unobtrusively anywhere in your home, it is a far cry from the standard alien black with extended antennas that its competitors choose to have for their router designs. But as great as it looks, we wanted to see if the hype lived up to the name and reputation Google has built over the years. Firstly, this is a mesh router system, which helps to eliminate any dead spots you may have in your home.

Perhaps we were using an older router, but the results made everything pale in comparison. Google Wifi router can be used as a single unit that can deliver a strong signal throughout a home of 1,500 sq. feet. But if you go all in and purchase the three unit set-up, you can get a really huge mansion fully covered by this gadget. Designed to deliver strong speeds and an impressive range no matter the size, design or layout of your home – Google wifi router proves to be the next step in awesome connectivity.

We have no mansion, but our three storied home made good testing grounds for the Google Wifi router. This is admittedly, not the fastest router in our range of testing, but it provides a good balance between various features and points that makes it a good buy. When we consider router options, we look at price, user friendliness, range and speed, and the Google Wifi router covers all 4 very well.

Usually companies seem to follow the adage ‘Form follows function’, but in this case, extra care was taken to the design and look of the router, without compromising on the functionality, and that is something we really appreciate.


It has a very easy set up, with Google’s Network Assist feature being a true help in giving tips on how to improve the performance of the unit. Coverage was great, and we always had one problem spot – our storage room in the far corner of the basement, yet even in that remote location, we received impressive speeds. (Not that anyone would be sitting in the storage room, lol.)


This is a great unit/ unit system for those who want a mesh system without paying double the amount, as is the case when comparing the Google wifi router to its competitors. It may not be the fastest, but it is the next step to simplifying installations and set up processes, and creating an app controlled router that has its own machine intelligence.

If you want strong range and coverage over your home – no matter how large it is, this is the gadget for you. If you also have a huge family, have lots of friends, or just have a techy house with tons of wifi connected devices – this is for you. We had at least 55 connected devices at any point of time, with no lags or drops in connectivity.

Google WiFi Router - OnHub Pros

  • Excellent coverage and range
  • No dead zones
  • Simple set up and installation
  • Automatic security updates to keep your network protected
  • Bluetooth antenna
  • Fast speeds for gaming and HD streaming
  • Great for multiple connected devices

Google WiFi Router - OnHub Cons

  • Do you really need this awesome device or can a simple router do the job – it is not for people with small living spaces.

4. TP-Link AC5400 Wireless Tri-Band Router (Archer C5400)

High Performance Wireless Router For Comcast Xfinity

The TP-Link AC5400 is the first AC5400 router we’ve ever tested, and we’re quite excited to see what results we get! It looks like it would look right at home at the top of Sauron’s tower or even a battle ground in a Streetfighter kind of game.. so I guess you know this looks pretty futuristic. I even expect it to suddenly fly off. This router has so many features that listing them out would take us all day, but here goes.

From NitroQAM (1024 QAM) to 4 stream technology, these advanced features will really take you closer to faster internet speeds and data transfers than ever before. Imagine boosting your game play, browsing, streaming and more!


As technology continues to evolve, it’s clear that our wireless gadgets need to keep up. When we tested the TP-Link AC5400, within a short while, we saw some pretty impressive results. We ran a series of tests on this high-end router, and this took the High performance title with good reason. Read on.

Firstly, the Quick Setup wizard got us online within a jiffy before we could tap our red shoes. The navigation is easy, simple and designed to be handled in two menus – basic and Advanced and both offer super clarity. The parental controls are better than most, and the simple user experience makes this a winner.

The Gigabit Ethernet port did deliver on near Gigabit speeds, and file transfers were a breeze. We can safely state that users of this router can enjoy smooth streaming, better than other routers available.

Our three story home is filled with gadgets of all sorts – ranging from multiple smart phones lying around, all connected, to laptops, computers, not to mention other devices like microwaves, phones, garage door openers, all devices that could interfere with the devices connected to the 2.4GHz band. We had all sorts of gadgets connected, with hardware ranging from the slower 802.11N connection to the faster devices using powerful adaptors.


This router is touted to be able to deliver 1000Mbps on the 2.4GHz band and up to 2167 Mbps on the 5GHz band. Although your data transfer speeds will always be determined by the connected device, even the 2.4GHz performed very well, reaching speeds of 143 Mbps. Of course, the tests for the 5GHz s what blew us away. We reached real world speeds of over 800Mbps (I know it’s nowhere close to the theoretical speeds of 2167Mbps as advertised), but this comes pretty close to reality. Just this alone makes the TP-Link AC5400 one of the fastest routers around. Even the Smart Connect Feature did enhance the speeds by 80%!!!


Gamers can rest easy, because the TP-Link AC5400 delivers super fast connectivity, which keeps your connection lightening fast so that you’re always one step ahead of your opponents. It will almost feel like you’re in the future looking back at them. When it comes to connecting multiple devices, all bandwidth hungry, and having heavy data transfers, the TP-Link AC5400 is our pick for the high performance best router for Comcast Xfinity.

TP-Link Archer C5400 Pros

  • Clear and friendly management console
  • A lot of thought has gone into the design and UX of the router – making it extremely user friendly
  • ​Responsive & Intelligent Smart Connect technology which allows automatic grouping of devices to particular wireless bands.
  • Optimized throughput
  • Is in a class of its own
  • Superb performance

TP-Link Archer C5400 Cons

  • Router is a little heavy – but it is fairly low key and can sit unobtrusively in the background

5. Netgear Nighthawk X6 AC3200 Tri-Band Wireless Router (R8000)

Best Tri-Band Wireless Router For Comcast (Editor's Choice)

Not only does the name seem futuristic and indicative of it being the answer to future proofing your home, but the X6 is probably one of best routers for Comcast that we’ve tested, that could be the best replacement option for the AC router you currently own. This is the first tri-band router to be released and was created for the IoT (Internet of Things), which means that is built to handle the load of many devices being connected simultaneously. With more gamers, users and load getting connected, the Netgear Nighthawk X6 has become the face of the next-gen of wireless routers.


We have to start off with Netgear’s Smart Connect feature, which automatically adjusts the load balancing, by examining a client’s speed and then allocating them to a certain channel. One concern we had with our last router was that it could not handle a large amount of devices connected, but the X6 rose up to the challenge. Created as an upgrade to Netgear’s R7000, we can see many improvements that have been made in terms of performance. Offering a total bandwidth of 3,200Mbps (1300+1300+600 – 2 access points on the 5GHz band) on the 5GHZ and 2.4GHz bands, we did see some more than decent speeds, especially with 20+ devices being connected.

If we have anything to say, is that this router still stands as the best router for Comcast for the sheer thought put into design, performance and consumer usability.


3200Mbps is just theoretical, and we can’t wait for the day when we can enjoy speeds as fast as that, but the R8000 certainly does deliver. Although you won’t see speeds that high (ask your ISP to buck up and get those speeds asap), you will notice that your home network’s speed has been boosted significantly. If three wifi networks are not enough for you, you can also take advantage of the 4 port Gigabit switch, gigabit WAN port and 2 USB connections. The Six MIMO antennas and the R8000’s Beamforming technology will help strengthen the connection to your devices.


Without a doubt, we would highly recommend the Netgear X6 (R8000) for large families who have many devices. So everyone can do their own thing, stream media on various devices.

Netgear Nighthawk X6 Pros

  • Innovative design
  • ​Collapsible antennas that can be folded up to put them out of the way
  • Potential 3,200Mbps bandwidth, so you know you’re future proofing your home
  • First router with AC3200 tag
  • 2 access points on 5GHz band can handle 12+ 802.11ac clients for heavy data transfers
  • Easy set up for first timers

Netgear Nighthawk X6 Cons

  • Overkill for homes with few connected devices

1. Motorola 16x4 High-Speed Cable Modem Router Combo (MG7550)

Best Modem Router Combo For Comcast Overall (Editors' Choice)

As more and more devices and people get connected to the internet, it stands to reason that our bandwidth should also consistently increase – which is has, if the past 5 years are anything to go by. With ISPs giving us access to high speed internet, the only thing that would hold you back is your router, which could be the weakest link in your internet chain. Sometimes having two separate devices can be a problem, but that’s where the Motorola High-Speed Cable Gateway comes in.

A true winner launched by Motorola, the MG7550 is considered to be one of the best modem router combo for Comcast.


The modem can reach speeds up to 686Mbps. While this doesn’t sound like much, considering that most routers these days can reach theoretical speeds in Gbps, if you’re really realistic, you know that we don’t currently have access (at least most of us) to super fast high speed internet. This is why the MG7550 is a good option. It can handle connection speeds as well as any other router.

If you’ve noticed your modem is causing your internet to cut out randomly, this may be the answer to your problems. It shines where others fail in full spectrum scanning. Other modems tend to offer specific channels in the spectrum, and more often than not, some of those channels get more crowded or have higher levels of noise. The MG7550 certainly improves on that performance.

The router on the other hand, is one powerful machine. Offering a maximum theoretical bandwidth of 1900Mbps, it also broadcasts a 3x3 MIMO signal which is a bit like beamforming, but actually creates separate networks for up to 3 devices. The Wifi Power Boost is a new feature that offers and delivers a better range than anything we’ve tested in this guide.


This modem router combo could pull all of what our ISP was offering in our subscription plan, and the wired gave us nearly 50% more speeds than what we were supposed to get from our ISP. This was only good news for us. This was when we connected our device directly to the modem (so we got 145Mbps when we were supposed to get 100Mbps). Wireless speeds were also impressive – perhaps this is the first impressions, but after two weeks and no change in performance we were quite happy with the MG7550. Perhaps we’ll feel different in a year’s time – but we’re hoping to hear your experiences on this one too!


For people who are looking to get a steal deal without compromising on performance and quality will be happy with the MG7550. This provides excellent range so people who have been experiencing dead spots with their old router should definitely try out this router.

Motorola MG 7550 Modem Router Combo Pros

  • Sturdy Build
  • Excellent Wifi Signal Strength
  • Heat sink and 3 thermal sinks to keep your device running cool
  • Quick modem boot as compared to other modems
  • Easy navigable interface
  • Offers consistent high internet speeds

Motorola MG 7550 Modem Router Combo Cons

  • Conservative Design

2. TP-Link N300 DOCSIS 3.0 Wireless Wi-Fi Cable Modem Router Certified by Comcast

5. TP-Link AC1750 WiFi Cable Modem Router Combo Certified For Comcast Xfinity

TP-Link has been gearing towards targeting a certain market and they’ve been introducing modems and routers that are in an affordable range with all the features that are essential for a lag – free internet experience. This is why the TP-Link Archer CR700 is considered to be one the best modem router for Comcast.


As the Bluegadgettooth team grew over the years, we had more bandwidth hungry devices getting connected. This meant that there was more load on our router and modem, but it was time to change it and we really wanted something that could handle the load without costing the Earth. The Archer CR700 performed better than many modem router combos in its range.

One good point to remember is that expensive does not really guarantee great or better performance. This is a great example of how a well priced product can still deliver better results than other products which can be double the price.

The signal strength was consistently strong, and as our team needs to be connected 24/7, it was important that each team member receive a good signal, no matter where they were in the office space. Our office has quite a few number of walls, and this tends to be an obstacle course for other tested modem routers, but the Archer CR700 went through all the walls like a summer breeze.

There were no dropped connections, no reboots and the set up was easy peasy. The only word of caution we would have for you is to avid purchasing the first version of this router as there were a few bugs. Fortunately, that version is out of circulation, but also read the fine print to be on the safe side.


Being on an acre large property meant that we needed a device which could deliver on speeds. The 5GHz speeds were impressive, delivering speeds of 112Mbps from a plan that is supposed to deliver 100Mbps.


The Archer CR700 is well priced and for the price, you do get an awesome deal. Having a modem router combo means that you enjoy huge savings instead of buying separate devices. People who are looking for an easy set up to get connected will appreciate the CR700.

Dual Band vs Tri-Band Router for Comcast Xfinity

Now we can see a lot more tri-band routers in the market, but are they worth the hype?

Tri-Band Wireless Routers

Tri band routers are reputed to offer speeds that far surpass the 1Gb wired speed on most devices available today. But are these speeds just theoretical or real world? Although many manufacturers concentrate on the ‘Speed’ factor as a sellng point,what makes the tri band router a better option vs the dual band is that they tend to handle multiple devices way better.

The added benefit is the boosted throughput as well, especially on the 5GHz band.

2 x 5 GHz Wireless Network vs 1 x 5 GHz

The difference between the two is that a dual band router offers only 2 wireless networks, one on the slower 2.4GHz band and the other on the faster 5GHz. Older devices which cannot be supported on the faster 5GHz spectrum get connected to the slower 2.4GHz band, and the more compatible and faster devices get connected to the 5GHz band, and all of this can happen at the same time.

As of now the highest speeds offered on dual band routers lies in the range of 450Mbps on the 2.4GHz band and around 1300Mbps on the 5GHz.

Now we get to the tri band router. It also uses the 2 frequencies of 2.4GHz and 5GHz, but instead of hosting a third network on a different band, it actually creates a third network on the 5Ghz band. If you’re new to the world of routers, it may be easy to get confused with thinking that a while new frequency is used. Actually this is how it is separated. There is one network on the slower 2.4GHz band, and two separate networks on the 5GHz band.

Why would this make a difference to your networks’ performance? This is because just like the older 2.4 GHz band, your 5Ghz band can also face congestion. Now we have a lot more gadgets that function on the 5GHz band, and it makes absolute sense to have that third connection which can offer more speed amongst all your connected devices, ensuring that none slow down.


Tri band routers offer theoretical speeds of 600Mbps + 1300 + 1300, which totals to 3200Mbps. Not real world as yet, but you know that day is coming soon.

As of now, which one works better for you depends on many bandwidth hungry devices you have in your home – so the decision lies solely upon you.

Finding The Best Router For Comcast Xfinity

This is where the search for the best wireless router or a modem router combo for Comcast starts, and as how everything in the 21th century works, the search begins online. It can get confusing though, if you’ve never shopped around for the best router for Comcast Xfinity, which is why our team has diligently tested, reviewed and chosen the best routers for Comcast users.

Remember, being the proud owner of your own router for Comcast means you can forget about paying monthly rentals, as well as getting something that is tailor made for your internet needs. Those monthly rental fees which are around $10 could pay off your own wireless router within the span of a year or less!

Routers are built to last, and the average lifespan of one router could be anything between five to ten years, which means HUGE savings for you. Another upside is that you finally get to enjoy the fast speeds you pay your ISP. Comcast has different subscription plans for users with various budgets and as Xfinity now provides unbelievable speeds, you really do need a router that can deliver the speeds you actually pay for.

How Much Does Comcast Charge For Router Rental

When you are planning to stay with the same Internet provider for a longer period of time, it does make economic sense to invest in a brand new router for Comcast Xfinity. Although purchasing a modem or a gateway involves a higher upfront cost, keep in mind that it will pay off for itself in one year or less, depending on the price of the device. For example, if the initial outlay for a Comcast router may run between $70 to $90, you will no longer pay a monthly fee. Which means you should break even on your investment in less than a year, somewhere between 7 to 9 months. In case you are going to relocate and switch to a different cable provider in less than twelve months, renting the wireless router might be a better option for you. You need to do the math for yourself and see what works best in your case.

Why it's better to buy your own router than rent it from Comcast Xfinity

When you sign up to Comcast XFINITY Internet service, you may choose either to buy a new router for Comcast or use the one provided by the ISP for a monthly fee. Comcast, the nation’s largest cable firm is charging around $10 in monthly fees for renting you their equipment. They also offer tech support for it. That means they will also offer a replacement of the unit if needed. (As long as the problem is on their end, not your’s!)

Although their customer agents may not mention it right away, Comcast customers may eliminate the rental fee from their bill by getting their own equipment. Cable operators will tell you that you’re on on your own for support with the modem/router, but you’re far more likely to have issues with your wireless router or your computer or tablet. It also means that you will be solely responsible for the upgrades. This is why you should look for a device with a two-year warranty.

If you are tired of being slapped with a never ending bogus rental equipment fee, buying your own router for Xfinity may be the right choice for you. Thus, you eliminate the monthly fees. Also, you won’t have to worry about failing to return the equipment and being charged couple of hundreds of dollars more.

Purchasing your best modem and/or router for Comcast Xfinity may bring certain advantages, such as:

#1 Save Money

Paying upfront might look that you are losing money in the short term, but on the long run, you will be saving more than you think. The monthly router leasing fees add up and by the end of the year, the company will charge you $120 or more. A quick-one time purchase of a gateway and you can start saving. By choosing a decent model priced around $100 or even less, at the present $10 rental fee per month, you will be saving money by the end of the year. It will pay for itself in under one year. You could actually save up to hundreds of dollars over time.

#2 Own your equipment.

At the end of the day, you own the device. You will not have to return it at the end of the contract, or when you are moving. You could still use it even if you change the Internet Service Provider, as long as it is compatible with the service you are paying for.

#3 Get A Better Router

When you have the possibility to choose the best modem router combo for Comcast, you save yourself a lot of trouble. By purchasing the best model for you, you will not have to worry about the rented modems issues you experienced before.

How to make sure that your router is compatible with Comcast

Before you go out and purchase the router of your choice for use with XFINITY Internet and/or Voice service, you need to ensure that it is certified for the Comcast service you are paying for.

Note that not all modems/routers/combos are compatible with Comcast. Only certain models are Xfinity Comcast approved. How can you tell if your model of choice is the best modem router for Comcast? You cannot rely only on the fact that it says it can support certain speeds! There are other requirements that need to be met in order to have it working with your service tier.

Is My Router Compatible with Comcast?

You can call Comcast and ask what models are compatible or simply find the needed information about the supported modems on their website. Comcast had made available online a DOCSIS Device Information Center that lists all modems compatible with their network. A quick visit to mydeviceinfo.xfinity.com. and you will find a list of all the certified retail equipment that's compatible with Comcast.

Purchasing Your Own Equipment

When you purchase your own equipment, it is your responsibility to ensure that the device is secure, certified and compatible. You will have to rely on your knowledge or your friends when it comes to troubleshooting issues or configuring your network’s security settings.

Comcast’s current and future customers are able to find compatible retail equipment automatically just by visiting the above mentioned website. The uncertified devices or “not supported” on Comcast network are referred to as “EOL” (End Of Life). Therefore, they will not be activated as new or replacement equipment.

You also need to ensure that the device is DOCSIS 3.0 compatible - it will enable you to enjoy improved performance. In the next years, most of the Internet providers will upgrade to DOCSIS 3.1 and its 1000 Mbps download speeds. Until that happens, you can stick with a DOCSIS 2.0 modem.

When You Should Buy a Modem Router Combo For Comcast Instead of Separate Devices

Before rushing to buy a cable modem router as separate devices or as a single unit, you will have to take into account your existing equipment. If you already have a high-end router, then you will need only a modem to connect it to.

Whether you decide to purchase a modem router combo or a separate unit, you really need to ensure that the model you chose is compatible with the service provided by Comcast. You can either contact them by phone or look for this information on their website.

There are several advantages when buying a modem router combo:

​#1 Space saver, easier storage.

By combining the router and the modem in one single device, you are able to save space on your desk and streamline your setup. One single unit is more space efficient and easier to store than two individual pieces of equipment. Not to mention that it reduces the total number of cables and wires you need to set up the network and connect to the Internet. Just having one single unit means there will be no extra wires messing up your front room or tripping up your pet. The combo unit performs both tasks of hosting the home network and connecting to your ISP. Remember that separate modems and routers work by communicating with each other via an Ethernet cable. When you go with a combo unit, that is one less cable you need to worry for. One the same note, modem-router combination is powered by a single AC adapter, so it reduces a power cable and frees an outlet. The modem router combo is a great option for those who have space and setup complexity concerns.

#2 Easier set-up

The installation process is simplified. You will have to install and configure only one device as opposed to two unique devices. Thus, the connection process is performed faster since you do not have to set up and configure two devices. Additionally, a combo unit ensures that your router and modem will not have compatibility issues.

#3 Money saver

There is no need to stop the savings at buying your own modem! You can maximize your savings by buying a modem router combo as they often cheaper than buying separate products.

#5 Troubleshooting

A modem router combo device is much easier. Instead of resetting two devices and waiting for them to reboot and regain signal in order to communicate with each other, all you have to do is reset the combo unit and it will run faster. Additionally, if you wish to reset the factory settings to fix either device, the combo unit's faster setup time will get you back up and running more quickly.

What to look for in a Modem Router Combo for Comcast

When you are ready to switch to a modem router combo, you will need to take in consideration certain factors such as: design, compatibility, performance, price, standards and the number of channels. You will need to ensure that the model you will purchase will be compatible with the Comcast service. In order to determine what are your best options, we need to look at the following factors:

Modem Router For Comcast

Compatibility/Comcast Xfinity approved

The fanciest modem router combo won’t help you much if your Internet Service Provider does not support it. On Comcast’s website you will find a list of compatible models approved by the company. Keep in mind that some models who work fine at a lower-speed tiers may not be approved when opting for a faster level of service. Therefore, prior to deciding what to buy, you should first contact Comcast and confirm that your top choice is suitable for the service you are charged for. As a general rule, all devices DOCSIS 3.0-certified by industry R&D firm cablelabs should work without any problem with a DOCSIS-based Internet service.

DOCSIS 3.0-Certification

You might want to ensure that you are getting a combo unit with DOCSIS 3.0 standard (Data Over Cable Services Interface Specification). Let’s see what exactly DOCSIS 3.0 means. DOCSIS is a telecommunications standard used by the cable TV operators to provide Internet service over the same cable. It helps adding support for multiple channels to increase speeds. Many ISPs servicing big cities, have upgraded their services to DOCSIS 3.0, enabling their customers to enjoy an improved performance. The latest upgrade is DOCSIS 3.1 (1000 Mbps download speeds) was launched in only a few test markets for the moment.


Most of the Comcast approved routers available on the market feature the same set of indicator lights: a power light, lights that tell you the status of your send and receive channels, a light indicating whether you have internet connectivity, and a link light that shows if your modem is connected to a computer, router or other device. What you should be looking for is a model that can display all of these light in a clear way. In case there is a problem, you would like to notice it right away. An easy-to-spot display would do the trick. Also, you’ll need to ask yourself how much space are you willing to allow on your desk for this combo unit. Are you looking to save some space and reduce the footprint of the device? In that case a compact slick design would not be an eyesore and it will blend in with the rest of your network and cable equipment.

Price and Warranty

The main reason most of the people chose to purchase their own modem router combo device is to save money. Eliminating the router rental monthly fee can help you save money on the long run. The idea is to choose a model that pays for itself within a year or less. Your break even point should be close to one year. That does not mean you should buy the cheapest model available on the market, unless your budget is really tight. You may want to purchase a new piece of equipment rather than a used or refurb. Most of the router manufacturers provide one or two-year warranty coverage.


Most of the router modem combos feature eight download channels and four upload channels which offer more than enough performance. You can get download speeds of less than 150Mbps. For an extra $10 or $30 you may get a model featuring 16 X4 channels for high-speed. But a 8x4 may handle whatever you throw at it for less money.

Different Types Of Wireless Routers For Comcast

The need for wireless has seen a tremendous growth in the past years. More and more people are connecting to the Internet. We are growing each day and we want our wireless capabilities to grow with us.

Wireless routers offer a lot of benefits, such as allowing us to work or simply enjoy using the Internet from anywhere and providing Internet access to our visiting guests.

Illustration and Explenation of Tri Band Routers

You probably heard or read by now that there are different types of wireless routers such as Wireless-N, Wireless-G or Wireless-AC. The first two are terms referring to 802.11n and 802.11g wireless networking standards set by Institute of Electrical and Electronics Engineers. The main difference between the router standards is speed and range. For example, Wireless-N increased the maximum data transmission rate more than tenfold from 54 Mbps to 600-900 Mbps.

A router’s performance varies by standard with 802.11b (the oldest standard) providing the slowest speeds at up to 11Mbps. WIreless G can deliver a maximum of speed o 54Mbps while devices based on the 802.11n standard are fastest, reaching 300Mbps.

Wireless-N also allowed wireless devices to use both frequencies 5GHz or 2.4GHz band in the same time. In Wi-Fi wireless networking, dual band refers to the capability to transmit on the 5GHz band of 802.11a and also the 2.4 GHz band used by 802.11b, 802.11g, and 802.11n. Unlike ordinary wireless equipment that only supports one signal band, dual-band routers contain two different types of wireless radios that can support connections on both frequencies. The 5GHz band is known to provide a better performance and coverage due to less interference.

Wireless-AC (AKA 802.11ac) is the new standard which offers major wireless connectivity improvement. It is a big leap from its predecessors, meaning it is the most powerful wireless network protocol currently available. Wireless-AC can send wireless at rates more than five times the best Wireless-N devices and hundred times the best Wireless-G devices.

In terms of speed, here is a breakdown of max throughput for all the three standards: Wireless-G: 56Mbps, Wireless-N: 600-900 Mbps and Wireless-AC: 1200-5300. As for the wireless range (radius), 75 ft vs up to 200-500ft, the differences between the standards are: Wireless-G: 20 MHz, Wireless-N:40MHz and Wireless-AC:20/40/80 MHz.

The best way to overcome interferences is to get a high-performing router Wireless-AC and upgrade its firmware to the powerful DDWRT or Tomato. This trick will enable you to have more control over the signal while improving signal strength and stability. Many of these routers have excellent hardware but the manufacturer’s firmware actually hinders their abilities. You will be surprised how much of a difference you will see in the gateway’s performance, once you did the DD-WRT upgrade or Tomato firmware enhancement.

If speed is what you are looking for then it might be the time to let go the Wireless-G router. You are sacrificing overall speed and security while actually hindering the wireless capabilities for newer gateways. In the age of warp speeds, Wireless-AC is not just a luxury: this is the wireless networking standard you need in order to fully enjoy your online experience.

Final Words

The main reason people want to purchase the best router for Comcast is to eliminate the monthly fees and save some money on the hardware. Nowadays you can get the best modem router combo for an affordable price and start saving on the long run.

Some people are attracted by the simplicity of an all-in-one device. Most of them fall in love with the ease of use, high performance or excellent range. Or it could be any other of the features of these modem router combos. Others may like them for their small footprint. In any case, there is no doubt that combining two devices in one and having a standalone unit was a great idea.

Purchasing your own equipment offers you flexibility and updated technology. Most of the electronics retails store offer discounts in order to encourage sales and customer satisfaction.

In addition, a big majority of the Internet Service Providers still use outdated firmware which can be a major impediment for you. Many ISPs are still offering DOCSIS 2.0 to their customers, while the current telecommunication standard is DOCSIS 3.0.

Bottom line? There are so many options out there, all waiting to help you save money.
