You also need a great modem that will be able to help you connect to it.
The modem is actually the device that helps you connect to the phone jack that will be on your wall. It helps in translating the internet signals into something that the electronic devices can understand.

What most internet service provider does is that they will install a modem at your place and will chat you monthly fees for it. You may also choose to get the router inclusive in that package or buy it separately. What many people do not realize is that buying a modem for yourself is as beneficial as buying your own router. It will actually cost you less money if you do that, math. Your rental fee for less than a year will cover the cost of a standard modem. Of course, if you want something that is more powerful, you would have to pay more.

- Features one 2.5Gbps port on the back
- Follows DOCSIS 3.1 framework, backward compatible with 32×8 DOCSIS 3.0
- Only a cable modem, no built-in router
When you’re looking for a cable modem, Motorola should be one of the first names to pop up in your mind. The company doesn’t make too many modems these days, but the ones it does are all top-notch products. This is the Motorola MB8611, and if you’re looking for a modem for comcast xfinity, you’ve reached just the right place.
This is a modem that has been specifically approved for Comcast users, and it comes with the ability to pair with all types of WiFi routers. This is a great thing to have on your modem as some cable modems tend to restrict you in terms of the kind of router you can use. Besides that, the first thing that you notice about this modem from Motorola is that it is a DOCSIS 3.1 device. It supports the latest DOCSIS framework and gives you a really good internet connectivity.
The MB8611 carries only one ethernet port on the back – but the good news is that this is a 2.5Gbps port, which means that you get the fastest possible internet access without even having to bond two ports together. Sometimes people get disappointed when they see that there’s only one port on the back, but when you connect that one port to the router, you can then use the router to connect other devices!
One more thing that people need to take note here is that this is a pure cable modem and does not carry any built-in wireless technologies, so there will be an additional cost involved – that of purchasing a router. This modem, however, uses some of the latest technologies to ensure you get the best internet access. This includes Active Queue Management (AQM), which helps reduce latency and improves app performances. This also makes it an ideal modem for those who are into gaming, streaming or video conferencing.
In addition to all this, what further cements this modem’s place as one of the best comcast xfinity modems is the fact that it comes with a two-year warranty period from Motorola, as well as a lifelong support from their US technicians. The router is also backward compatible with 32×8 DOCSIS 3.0.
- Supports all wireless routers
- Comes with a high-speed 2.5Gbps ethernet port
- Supports active queue management which helps reduce lag
- Two-year warranty period
- Supports a number of other ISPs too

18. ARRIS SURFboard T25 DOCSIS 3.1 Gigabit Cable Modem
- Runs on DOCSIS 3.1 framework
- 2 LAN ports and 2 Telephony ports on the back
- Only a cable modem, no support for wireless internet
When it comes to the look and feel of it, the T25 is exactly what you would expect from a typical Arris modem. It carries the same box-like look and design aesthetic from ten years ago. However, in terms of performance, there’s absolutely no questioning the T25 as it is a superior product than most of their lineup out there. This is a DOCSIS 3.1 cable modem from Arris, which does not feature a built-in router. However, as far as pure cable-modems without a router are considered, this totally ranks among the top names in the list.
This is one of the best Comcast Xfinity compatible modems that you can find in the markets today. We say this because the modem has specifically been created for Xfinity users. Unlike many other cable modems out there, this one also supports a voice service, which is a big plus point, as that feature has been disappearing from so many modern-day modems.
The T25 comes loaded with a DOCSIS 3.1 framework with a 2×2 OFDM framework. However, it also supports backward compatibility with DOCSIS 3.0 connections, thanks to the 32×8 channel bonding setup. When you turn this modem around, you can find two 1 Gbps LAN ports on the back, as well as two other ports for connecting the telephone lines for Xfinity’s digital voice service.
The Arris Surfboard T25 is an ideal modem for Xfinity users who are using plans up to 1 Gbps in speed. While this is an ideal product and one of the best Xfinity-approved modems out there, the only drawback that we sense here is the lack of WiFi features in it. This, as we’ve mentioned before, is a pure cable modem. However, you can connect practically any WiFi router to it and it will be supported. There are no restrictions to a brand over here. If you’re on Xfinity, this one ticks nearly all the boxes!
- Supports digital voice service
- 2 LAN ports and 2 Telephony ports on the back
- Built specifically for Xfinity users
- Supports all WiFi routers
- Supports backward compatibility with DOCSIS 3.0 networks
- Does not include a built-in WiFi router
Ultimate Buyer’s Guide: Thing To Keep In Mind When You Are Looking For A Comcast Xfinity Compatible Modem
- First and foremost, you should decide whether you want to buy a modem or a router modem. If you have purchased a modern router recently, then you are in luck because most modern routers are compatible with all kinds of modems. Still, if you have none, then it is better to buy the modem and router separately because if something happens with any of the two, then the whole system has to be changed. Buying the two separately also costs less to repair or change separately.
- You should also check the DOCSIS protocols; most of the models featured in this list have either of the DOCSIS 3.0 or 3.1 protocols. It is an acronym for data over cable service interface specification. It is the protocols that allow your modem to provide broadband Internet access. If your internet service provider offers internet speeds of more than one gigabyte, then you should look for the 3.1 version, but for most households, 3.0 will be sufficient.
- When wearing the modem, you will also notice figures written like 8 x 4 or 32 x 8, which indicates or downstream or upstream channels. This means how much downloadable data your ISP can provide at a time. If you work from home, then you want a bigger number on the box.
- You should also go for a modem that has good upstream as well as downstream speeds prescribed on the box because this will future-proof your modem, and you do not have to buy new modems when you go for costly high-speed internet connections packages.
1. What Is A Modem?
A modem is actually short for ‘modulator-demodulator.’ It can be defined as a hardware component that allows a PC or another device, like a router or a switch, to be able to connect to the internet.
2. Should You Buy A Modem Or Rent It?
Whether you should depend upon various factors like whether your company is paying for your internet service, the place you are residing in is just a permanent, etc. If you are staying in your permanent residence and you are paying monthly fees to your internet service provider for renting the modem, then you should buy a new one for yourself.
3. Are Modems Very Expensive?
Many people do not buy their own modern because they feel that it will be very costly, but this is not the case if you do the math right you will see that the monthly rental feel that you are paying for your modem that is provided by the internet service provider is actually more than the cost of a modem.
4. Does A Modem Come With A Router?
A modem makes a computer router or may not, and it depends upon the model. It is better that you do the necessary research before you buy your modem. If you want a 2 in 1 solution, then those are also available.
5. Which Is A Good Modem For High-Speed Internet Connection?
There are many good modems for high-speed internet connection like Motorola MB7420 Cable Modem, Netgear CM700 Cable Modem, Arris SURFboard SB6190, etc.
6. Is Purchasing A Router Mandatory If You Have A Modem?
No. If you do want to have a WiFi at your place, then there is no need, but if you are concerned about extra expenses, you can go for a modem that has an inbuilt router.
7. Can I use a modem that hasn’t been approved by Xfinity?
Yes, you can use a modem that hasn’t really been approved by Xfinity, but you should keep in mind that it might not give an optimal performance that an approved modem would. In most cases, that shouldn’t be a problem, because almost all DOCSIS 3.1 modems that support cable-based Internet Service Providers can easily support Xfinity networks. However, while you can use non-approved modems too, it is best advised to use the approved ones for a stable connection and a better performance overall.
8. Where can I buy the best modems for Xfinity internet connections?
The place where you can buy the best modems for Xfinity internet connections is Amazon. While you can visit a physical electronics store near you to get hold of these modems, the benefit of getting them from the Amazon web store is the fact that they provide you with a much larger collection than compared to any other store that you are going to visit. On Amazon, you can find hundreds of modems from different manufacturers and get them delivered right at your doorstep. Besides all this, Amazon also offers an easier return policy and better discounts.
9. Which company makes the best DOCSIS 3.1 modems for Xfinity?
While there are many, many players in the markets who make DOCSIS 3.1 based modems for Xfinity users, in our experience the top three names in no particular order are Netgear, Motorola and Arris. All three of these have been coming out with some of the best-selling and the best-rated modems and are among the most reliable names. They have had quite an experience in making network equipment and these modems (including some modem/router combos) are among the finest that you can find in the markets.
10. How can purchasing a Comcast Xfinity compatible modem help me save money?
There are two options to you – you either purchase a modem or you rent it from the ISP. Renting the modem almost always involves a monthly fee that you have to pay for it, and even an additional security deposit in some cases. While different ISPs cost different amounts, Comcast Xfinity has one of the highest such charges at $14 per month. This means you are paying $168 per year for the modem rental charges. At that price point, you can actually buy a pretty good modem and use it for multiple years – saving you $168 a year in rental costs.
11. Is it ok to buy a second-hand (renewed) cable modem?
Renewed cable modems are a good option only if you want to use them as a backup or a secondary device, or use them only for a short period of time until you get a better modem. This is because modems deteriorate with time and usage, and they keep heating up more and more with time too. Basically, the older the modem is, the shorter the time it can perform before you need some maintenance on it. Hence, we recommend these renewed and second hand modems only to those people who plan on using it only on a short term basis. However, these modems can be quite cheaper compared to buying new modems – so that’s one major advantage.
12. Can I use internet connections of another ISP on an Xfinity approved modem?
Yes, you can use internet connections of another ISP on an Xfinity approved modem. That is possible – but only if these other internet connections are also cable-based. Since Xfinity is a cable based service, it works only on cable modems – and supports only those connections that offer on a similar means of operation. These include popular services such as Cox, Spectrum, WOW, RCN, etc, all of which operate on cable networks. Internet flows into these modems with the help of a coaxial cable. You cannot make use of fiber optic based ISPs or DSL based ISPs on these types of modems.
13. How to make sure my Xfinity compatible modem does not heat up?
In order to make sure that your Xfinity modem is not heating up, you’ve got to take care of three factors – firstly, you’ve got to make sure it stays away from all water. We know that water is the biggest enemy of all things tech and electronic, and hence you’ve got to keep water away from it. Other than that, you need to keep it away from boxed areas – because a good modem requires a good airflow in order to keep things cool. Lastly, you need to keep things dust-free, as dust can clog the heat vents and areas for the heat to exit on the modem, leading up to the modem heating up even more.
