10 Best Routers For Comcast Xfinity (Updated 2018)

It’s clear that you need a good wireless router to access the internet wirelessly. Agreed?

But if you’re a Comcast Xfinity subscriber, you’re paying rental fees for something you don’t even own! The small fees quickly add up, especially at year end when you’re looking at your expenses. That sounds ridiculous to me!

That would perhaps be somewhat acceptable if Comcast Xfinity gave you an awesome wireless router or modem router combo that delivered on exceptional performance. Let’s be honest, you’ll be better off with your own best router for Comcast Xfinity, especially when it comes to boosting your wireless performance and connectivity.

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

Just looking at the performance reviews of each should tell you why replacing your old Comcast router with your own is a very good idea.

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

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 wireless router for Comcast Xfinity Internet.

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 Xfinity

  • 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.

When you are shopping for a wireless router or a modem router combo for Comcast Xfinity, 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.

Gaming and Streaming Router

If you’re into HD gaming or streaming, you will be hunting for a high performance router – and you will need it to have the following: It should have three bands, reach incredible speeds and give better coverage, range and overall performance so that the only thing you have to worry about it your gaming performance.

Wireless Router For Large Homes

If you’re home is on the larger side of things, if you have a home in the suburbs or a large acreage, then you will need a router like the Google Wifi router, Linksys Velop or Netgear Orbi which can work its way through obstacles like walls and interference from many household gadgets that work on the 2.4GHz. Nothing can be more annoying than finding your favourite place in your home is a wifi dead zone.

Low Budget Wireless Router

For those who don’t have a huge bank balance will appreciate the cost effectiveness of a modem router combo. The sheer amount you save on modem router combos will leave you connected, but with more in your pockets than if you went and bought separate devices.

Editor's Choice

Leaving the best for last, our Editor’s Choice is the true winner of all our tests – when it comes to being on top in terms of performance, range, build, design and more. There is a huge range of testing that goes into finding the perfect winner. And when it comes to being the best of the best, the bluegadgettooth team found that the Motorola MG7550 really came through with flying colors.

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.

1. Linksys EA7500 Dual Band Wireless Router

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

Time and time again, this router has topped most of our guides as being our Editor’s pick. When you read through our review, you’ll understand why.

Design wise, it is rather stylish and sleek. At least your router won’t look like an eye sore in your room. Isn’t it nice to have something look good rather than a tower of black with alien antennas sticking out?


What the BlueGadgetTooth team really liked was the easy set up process. Nothing can be more frustrating with fiddling with wires and buttons and getting nowhere. This router is extremely user friendly, and that is a major reason why this is our Editor’s choice. There are no CDs involved, just a simple web browser for your configuration process. You can simply create a free Smart wifi account so that you can access your network remotely and even manage/ control it via the Mobile app.


When it came to speeds, the Linksys EA7500 really took us by surprise. We want to mention he 2.4GHz band first. When it comes to routers, we’ve been noticing a pattern. The 5GHz band is always the best and somehow, the 2.4GHz gets left behind. Understanding that there are still many users with older gadgets that do not support newer wireless standard or can’t cope with the 5GHz band, Linksys concentrated on improving the 2.4GHz band. And boy, did they ever.

The 2.4GHz throughput was unbelievable, scoring an impressive 166Mbps, give or take a few Mbps at a close range, and we really appreciated this, considering the amount of devices we had that connected to the 2.4GHz band. At a distance of 30 feet, the speed dropped to 127Mbps.

Linksys did not ignore its 5GHz band. No way. The performance of the 5GHz band was brilliant, topping our testing charts. If you go through our guides, you’ll notice that this router consistently is a leader in our guides. Speeds reached 642Mbps at close range, with the speeds dropping to 512Mbps at a distance of 30 feet.

We will be the first to admit that this is by no means the fastest, but when you look at all criteria such as performance, cost, range, reliability, looks and more – the Linksys EA7500 remains as our choice for best router for Comcast.

The file transfer performance was exemplary as well, with a writing and reading speed far higher than other routers we tested.

Best Use

This is a great option for those who are looking to get an awesome deal, be on top of their connected world, without spending every last cent you own. When it comes to choosing the best router for Comcast Xfinity, the BlueGadgetTooth team stands behind the Linksys EA7500. With its reliable performance, this router would be great for people with larger homes, for people who are looking for an improved wireless performance and simply, for those who are looking to get their money’s worth without breaking the bank.

Linksys EA7500 Wireless Router Pros

  • Excellent throughput
  • Supports MU-MIMO
  • Multiple management options to keep the average and advanced user happy
  • Sleek design and can be wall mounted
  • Delivers excellent speeds
  • Simple and easy installation process
  • Excellent wireless performance

Linksys AC EA7500 Wireless Router Cons

  • Only one USB 3.0 port

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 Xfinity 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 Xfinity 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 on 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 Xfinity 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 (Editor's 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

Best Low Budget Modem Router For Comcast

TP-Link made the TC-W 7960 modem/router quite compact and energy efficient. You will be surprised to see how nice this model is for the price point. It averages about 8 watts in bridge mode and 11 watts in router model. The TC-W 7960 gateway is CableLabs Certified and performs great on 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.

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

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.

How To Choose The Best Router For Comcast Xfinity Internet

Wireless Router Specifications

There are many factors that go into choosing the best router for Comcast Xfinity Internet. You’ll be right in thinking that just about any router won’t do. The router you choose depends on the following factors:

Speeds: It's clear that this is a very important point. Are super fast speeds vital to you? Do you work from home or need to constantly transfer heavy files. There are various routers that focus on speed, and offer faster speeds and are more geared towards future proofing your home for Gigabit speeds.

Your Xfinity Package: Your internet speed is only as good as what your ISP delivers. If you are on a certain tier, you can’t expect to receive speeds faster than what you pay for, regardless of what is advertised for a router. Check your Xfinity internet plan to determine which router would be better suited for your internet plan.

Your Online needs: What do you need your router for. Is it for better coverage or to eliminate dead spots in your large home, for a better online gaming experience, for simple data transfers, streaming HD video and more. Knowing what you need a router for will greatly narrow your options to pinpoint exactly what you really need.

Compatibility: You may prefer one router, but you will need to check if that router is compatible with Comcast. There is nothing worse than finally selecting one router, buying it, only to realise that it is not compatible when you’re setting it up.

What Xfinity Internet Package Should You Get

Slow Comcast Internet

Understanding that one speed is not good for all, Xfinity has various subscription plans for their users. Let’s take a closer look at their subscription tier to fully understand how knowing about these plans will help you in your search for the best router for Comcast. Our recommendations tie up with the Xfinity plans to make your lives easier.

Performance Starter Plan: This is the starting plan which gives you speeds of 10Mbps. If you are not a heavy internet user and don’t put a lot of load on your network or have many connected users, this plan could work well for you. Similarly, if you are subscribed to this plan, you would be better off getting a router like the Netgear Nighthawk R6700.

Blast! Internet: You can zip up to speeds reaching 75Mbps. This is a great plan if you have many family members who want to watch their own shows or share your internet with friends and family. This a great option for those who don’t want to wait for the movie to load during movie night. We recommend getting the Motorola MG 7550. Not only will you be able to access fast speeds, but you’ll be saving money overall as well. If you have a large area to cover with these speeds, you should get the Google Wifi Router.

Extreme 150: As the name says, you’ll be signing up for 150Mbps and these speeds will definitely ensure that your online experience is flawless. But you will need an awesome router to be able to handle these speeds and we feel the Netgear Nighthawk X6 will be more than adequate to handle all your online demands.

Gigabit Internet/ XFINITY Gigabit Pro: You can reach speeds up to 1Gbps/ 2Gbps with the Gigabit Internet and Xfinity Gigabit Pro respectively. These plans haven’t been offered to us yet, but if it is in the pipeline for you, we would recommend getting the X6 or even the TP-Link AC5400.

Make Sure That Your Router or Modem Router Combo Is Compatible With Comcast Xfinity Internet

This is really, really important and we cannot stress that enough. You may be dazzled by top of the line features, but all that would be wasted if your router or modem is not compatible with Comcast Xfinity.

You should:

  • Check Comcast’s website to see their list of approved modems/routers.
  • If the list is not immediately visible, verify your device’s compatibility and input your device’s details into the specified area. If your device shows up with a green light – you’re good to go. If there is a caution sign, you stand the chance of having an incompatible device.
  • Why it is important to do this is that many modems may not be able to handle upgraded speeds or even may be older and reaching their EoL status. You want to avoid this at all costs.

How To Set Up Your Comcast Xfinity Router or Modem Router Combo

You have your router, and you’re not sure of what to do next? Here’s our Quick set up guide to help you on your way.

Step 1

Connect your modem to a power outlet through the power cord and to the internet via a coaxial cable.

Step 2

Call up Comcast to activate your modem via Technical support. Give details like your MAC address and Serial number of the new modem/ modem router combo you wish activated and they will walk you through it, getting your internet up and running within 5 minutes.

Activation NOTE: Now all that is left is to activate your connection via your new router. You should open a web browser (connect your device via an Ethernet cable) and you will see an ‘Activation Welcome’ screen. If not, head to

Input your details (Check the Activation Information card included in the package) or sign in with your Xfinity username. If you already have a sign in name, you’re lucky and the process is a lot shorter. Just click on the ‘Sign In’ button.

If you don’t have a sign in name, create a new Xfinity username and put in a new password. Select your security question, and head to the next step, which is proceeding from the connection Established screen.

Step 3

Connect your devices to your modem and router and you can now get ready to rock and roll. Ensure that you secure your wireless network by creating a new network name and password on your router. You then have to update this info on all your connected devices.

Step 4

Return your Comcast provided modem or router and ensure that you inform tech support to remove rental fees from upcoming bills. Voila! Savings start straight away!

How Much Comcast Charges For Rental and How Much You Can Save

Router Rental Fees

Everyone loves to save a bit here and there, but when it comes to renting your device from Comcast, you’re simply throwing money down the drain.

If you check your monthly bills, and you are renting from Comcast, chances are you’ll notice a $10 rental fee. That may not seem like a lot for the convenience of not handling anything to do with your modem or router, but that adds up to a whopping $120/ year.

Renting vs Buying a Wireless Router For Comcast

Buying your own wireless router is always a good thing, but it may not be for everyone.


  • Direct free tech support
  • Great for people who are constantly moving house or changing ISPs

Buying your own:

  • Regardless of which device you purchase, you will automatically have savings of $120/ year, which is the amount you save on rental fees.
  • You get a device with better performance and features that will actually cater to what you want out of your internet.
  • You stay more relevant in case there are speed upgrades from Comcast, or if you suddenly have a roomful of people who want access use your network.
  • Better management features as well as advanced security settings to keep your private network secure.
  • You pay for something you can actually own, instead of paying fees for something you won’t.

Router vs Modem Router Combo vs Modem

To really know whether you should opt for separate devices or simply cut the hassle and go for a modem router combo, you have to know the basics of what each device does:

Cable Modem:

Cable Modem

This is your gateway to the online world. You cannot access the internet in your home without one of these and it translates digital data into electrical data and vice versa to relay information via various mediums, such as your cable lines or phone lines.

Wireless Router:

Wireless Internet Router

A router is what helps you connect your devices wirelessly. In today’s world, nobody really wants to be tied down to one spot, and with the number o mobile devices increasing, having a good wireless router is imperative.

Modem Router Combo

Modem Router Combo

This device is a combination of the two above mentioned devices and negates the need to buy separate devices. This is a 2-in-1 device which handles the functions of a modem and router alike.

You can read more about them here.

Which one is better? The decision lies solely upon your shoulders. The BlueGadgetTooth team tends to lean towards getting a separate modem and router, as you end up getting more access to many more advanced settings than a modem router combo.

A modem router combo eases the burden of going through the process of finding a router that is compatible with the modem you just selected, and finding the best deal. Having a 2-in-1 device helps make the choice easier.

If you are looking for a simple fix to your internet problems, and want to buy a device that can handle mostly anything you can throw at it, you should go for a modem router combo. However, if you are looking to really customize your network, the clear option is to opt for a separate modem and router.

How to Login To your Xfinity Router

  • 1. Connect to your network
  • 2. Open the web browser of your choice and type
  • 3. Enter login details like your username and password. This is usually a default login. Username: admin/ Password: password
  • 4. Click on the Change password button and change it so that it is not easy for anyone to access it

Dual Band vs Tri-Band Router for Comcast 

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.

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

Wireless N, Wireless-G, Wireless-AC

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.

Wireless Standards

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.

Custom Firmware

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

Comcast is a huge giant in the internet business and their rules tend to dominate the space. As a customer of Comcast, you may be saddled with modem rental fees without being none the wiser, thinking that the modem you are renting from them is part of the fee you pay to Comcast just for your subscription plan. Well, hopefully this guide wizened you up.

You end up paying money for a device that is neither up to date or current with the latest devices, nor do you own it. It really does not sound like a good deal to me.

If you decide to take the plunge and buy your own modem and router or a modem router combo, you can’t go wrong with any of the options listed in this guide.

Whether you are on the lookout for a great deal overall, or a high performance one, or even that suits your budget, there is a router or modem router combo that will cater to what you are looking for out of your device.

BlueGadgetTooth has thoroughly tested these devices to bring you reviews that will help you make the best choice for your internet needs.

Comcast Xfinity has some great points, like the huge network they have or that they are so widespread in the country, but when it comes to getting the best deal out of your contract, buying your own device is the best decision you will make.

Go for it.
