The Best Xfinity-Compatible Modems

If you’re looking to curb your internet costs without compromising on the package itself, buying your own modem would prove a wise choice. As you won’t have to rent out modems from your internet service provider, the $10 added expenditure that makes its presence known on your bill every month will disappear, instead it will reflect the cost of purchasing the device once and for all.

Choosing the right modem, however, can be a little tricky. Depending on which internet service provider you’re using, you must get a device that is compatible with their service. In the case of Xfinity, there is a range of modems out there that promise to give you stellar performance. We’ve compiled a list of seven Xfinity compatible modems that you could choose from.

Best Modem For Xfinity

Netgear Cm700 - $89.46

Netgear offers modems with the speed that out-speeds the competition. With maximum download and upload speeds reaching 1.4Gbps, it has a total of 8 upstream and 32 downstream channels, beating all other contenders. Nicely-packaged in a well-ventilated black case, the rising temperatures of the modem chip are regulated throughout your use giving a great user experience.

Keep in mind the device is just as good as the package you subscribe to. If you’re unwilling to pay for the bandwidth thinking that your modem needs to realize its full potential, paying extra for the high-speed modem would be an exercise in futility. Again, if you’re into online gaming that is when the downstream capabilities of the device will come in handy.

If you don’t use Xfinity Blast or Xfinity Extreme internet packages, you might as well buy the networking mogul’s CM400, CM500 or other variants and save some cash. To figure out your needs you might want to research What Is A Good Internet Speed.

Unlike most modems that come with a two-year warranty, Netgear offers a one-year warranty across its devices. Given the speed it offers, the warranty hardly impacts decision-making by consumers in most cases, but if you’re one of those who like to play it safe Motorola MB7621 might suit you better.

Motorola MB7621 - $77.99

This modem offers one of the most competitive speeds available across the US. It can handle a total of eight upstream and 24 downstream channels and since it’s a DOCSIS 3.0, it works well with plans offering speeds of up to 600Mbps.

If you truly are someone who likes to play it safe, it will delight you to know the device is compatible with a range of internet service providers including the likes of Cox and Spectrum, giving you greater flexibility while switching between providers. Cheaper than Netgear’s CM700 and offering a two-year warranty on the device, Motorola MB7621 is the ultimate choice.

The only downside to the device is that not many reviews are available to guide you as compared to other modems.

Arris SVG2482AC – $177.50

Arris SVG2482AC is unique as it’s the only modem that supports Comcast Voice, opening the doors to the world of Triple Play packages. Another great feature is the inbuilt router. The AC-band Wi-Fi router projects your wireless networks throughout your house, allowing you to place your modem-router anywhere in your home with ease. The SVG2482AC has two USB ports, four Ethernet ports and can support two voice lines simultaneously.

However, these options don’t come cheap! Costing more than double the other modems, a whopping $177.50, you might want to go for other options if you have simpler needs. It’s important to note the device is capable of download speeds up to 1Gbps, less than the Netgear device.

Given the money you’ll save on your monthly bill though, you’ll still be able to afford the luxury that SVG2482AC offers, especially if you have signed a multi-year contract with your internet provider. If this is what you desire, the SVG2482AC is the modem for you.

Arris SURFboard SB6190 - $85

Arris manufactures devices that are the most Comcast-compatible modems out there and it’s their modem, the SURFboard SB6190 that tops the list. The standalone modem, paired with a Wi-Fi router can provide download speeds reaching 1.4Gbps and upload speeds up to 262Mbps. The one-gigabit Ethernet port on its color-code backplate is a worthy addition that will facilitate your internet needs. It cost $85 but if you are willing to wait for a sale, it could cost you less.

Considering that once you get the device you will need to install it and troubleshoot it when problems arise, the status LEDs will have your future-self thanking you already. The massive support network of people who have used this device before will also be a source of help and insight along the way, ensuring that you have a good experience. It is one of the main reasons why we recommend SB6190. No matter your lack of expertise regarding technology, the community will help you eventually overcome it all.

Comcast has obvious investments in Arris which does lead to high performing devices when paired with Xfinity, but it is worth noting that not all the modems launched have been received well. In addition to this, when Arris releases new models, the older models are dubbed outdated even when the tech performs just as well as before. SB6190 is a similar case, it was released several years ago but remains to this day one of the fastest modems.

If you think the SB6190 is pricier than what you’d like, you could consider buying the Arris SB6183. The cheaper device is not as high-performing but can fully satisfy the needs of most small and medium-sized families. Tech21Century gives a comprehensive comparison of the two and can help you make an informed decision.

TP-Link TC-7610 Cable Modem -$54

This reasonably priced modem supports all Comcast packages, even the Extreme 150 plan, and offers the standard 343 Mbps download and 143 Mbps upload speeds sufficient for your daily needs.

It offers almost the same features as the SB6190, albeit at a lower price. Well-known within the networking world, the brand’s TC7610-E is an efficient plug-and-play box.

Zoom 5370 Cable Modem - $49

If you want an even cheaper option, you might want to consider the Zoom 5370 modem. While it looks nothing fancy, it has specs similar to the SB6190.

The device has 16x4 configurations of bonded upstream and downstream channels and a download speed of 686Mbps, the same as the Arris device. It has one Ethernet port which could be all that you’ll ever need and comes with a two-year warranty. If you want to save a couple of bucks, this could be for you.

Cisco DPC3008 Cable Modem - $99.95

There are quite a few people who want reliable performance at a value price. Those looking to save on monthly fees and who could do with bare-minimum performance should opt for the Cisco DPC3008. Offering a maximum upstream speed of 120Mbps and a downstream speed of 340Mbps, it is fast enough for the most basic Xfinity plans. However, it could prove to limit if you have the gigabit internet package. It has one Ethernet port, a coax port and is compliant with DOCSIS 3.0.

Conclusion

These modems are the best devices out there that are compatible with Xfinity. Whether you have basic cable, a double play or even a triple play, there is at least one among the above-mentioned that would fulfill your needs. With prices ranging from $30 to $180, there is something for everyone from the monetary viewpoint too. You can easily say goodbye to renting out devices from various companies and switch to your very own. It’ll save you big bucks in the long haul.

If you want to know whether the modem you like is Xfinity compatible, you can automatically find compatible retail equipment. If you’re an Xfinity internet or voice customer, visit mydeviceinfo.Xfinity.Com and just sign in. You’ll see information about the device you already have.

Even if you do not subscribe to their service, you can still use it to find out if the device is compatible, by using your address and putting in the internet speed you want.

Disclaimer:

You must bear in mind, however, there are advantages to using the Xfinity Wireless Gateway. It gives you access to value-added services like xFi, their Wi-Fi management platform, and allows you to use the home-based Xfinity Wi-Fi hotspot.

In addition to this, if you’re purchasing your own device, you must make sure that your retail device is secure and certified and that it supports the internet speed you’ve subscribed to with Xfinity. You’re also responsible for upgrading the device when Xfinity upgrades its internet speed. You’ll have to stay up to date with new developments in technology too if you’re to understand fully when you need to replace your modem.

In case problems arise, it is important to note that you, yourself will be the one responsible for troubleshooting these issues using the manufacturer’s manual if Xfinity finds that there is no problem at their end. You will also be responsible for configuring the wireless network’s setting whenever applicable. If you find these responsibilities will prove too much for you, you can still opt for the rental devices that come with the package and save yourself the hassle.
