Our Top 10 Picks for Best Modem Router Combo for Xfinity

#1 NETGEAR C7000-1AZNAS – Ideal for: High-Performance Streaming and Gaming

In our tests, the NETGEAR C7000-1AZNAS quickly proved why it’s our top pick. Right out of the box, the setup process with Xfinity was refreshingly simple, a sentiment echoed by many users who reported being up and running in under 30 minutes. Performance-wise, this device is a workhorse. It handled our 600 Mbps Xfinity plan without breaking a sweat, consistently delivering speeds that met and often exceeded our subscription rate. We connected multiple devices—laptops for work, a console for gaming, and several smart TVs streaming in 4K—and experienced no lag or buffering. The AC1900 Wi-Fi speed and 32×8 channel bonding create a robust and stable network that can handle a demanding household. The signal strength was impressive, easily covering our entire two-story, 1,800-square-foot test home with a strong and reliable 5GHz signal. One user aptly called it the “Usain Bolt” of modem routers, and we’d have to agree. While we had a smooth experience, some users have noted that long-term reliability can vary, with occasional units failing after a power outage. However, for its raw power, ease of use, and ability to eliminate rental fees, the NETGEAR C7000-1AZNAS is a stellar investment.

#2 ARRIS G18 DOCSIS 3.1 WiFi 6 Modem Router Combo – Perfect for: Future-Proofing for Gigabit Speeds

If you’re looking to prepare your home network for the future, the ARRIS G18 DOCSIS 3.1 WiFi 6 Modem Router Combo is an outstanding choice. The combination of DOCSIS 3.1 and Wi-Fi 6 technology ensures you’re ready for the fastest multi-gigabit plans Xfinity has to offer. In our testing, the setup was incredibly straightforward using the Xfinity app; we didn’t even need to make a phone call to get it activated. The speed increase was immediately noticeable, especially compared to older DOCSIS 3.0 models. It provides a stable, high-speed connection that’s perfect for households with numerous smart devices, 4K streaming, and online gaming. Many users confirmed our findings, noting a significant jump in their download speeds and more reliable whole-home coverage. The Wi-Fi 6 standard is particularly effective at managing network congestion, so even when the whole family is online, performance remains smooth. While the ARRIS brand has received some criticism for customer support and occasional quality control issues on older models, our experience with the G18 was flawless. It’s a powerful, forward-looking device that offers great value.

#3 Motorola MG7540 Cable Modem Wi-Fi Router – Suits: Reliable Everyday Performance for Mid-Tier Plans

The Motorola MG7540 Cable Modem Wi-Fi Router is a testament to the idea that you don’t need the absolute latest tech for excellent performance. This DOCSIS 3.0 workhorse has been a reliable choice for years, and for good reason. During our evaluation, it delivered consistent, stable speeds that perfectly matched our 300 Mbps Xfinity plan. Setup was a breeze; we followed the included booklet and were online in minutes. What we particularly appreciated was its dual-band capability and AnyBeam beamforming technology, which helped direct the Wi-Fi signal to our devices, ensuring a strong connection even through the plaster walls of our older test home. Many users reported similar experiences, praising its long-term reliability and the dramatic speed increase they saw after switching from ISP-rented equipment. One user noted their download speeds jumped from 65 Mbps to over 300 Mbps just by switching to this device. It’s an ideal solution for anyone on an Xfinity plan up to 375 Mbps who values stability and simplicity over cutting-edge features.

#4 NETGEAR C6250 Cable Modem Wi-Fi Router Combo – Ideal for: Budget-Conscious Small to Medium Homes

For those on a more modest internet plan (up to 300 Mbps), the NETGEAR C6250 Cable Modem Wi-Fi Router Combo offers a fantastic blend of performance and value. We found this unit to be a solid, long-term performer. It’s compact, easy to set up, and delivers on its promises. In our testing on a 200 Mbps plan, we consistently achieved speeds well over that mark, seeing a jump to nearly 240 Mbps. The Wi-Fi coverage is rated for up to 1,500 square feet, which was accurate in our experience, making it perfect for apartments or smaller two-story homes. One of the standout features noted by longtime users is its durability; one reviewer mentioned it has been in service for five years without a single issue across numerous devices. While the setup with Xfinity is generally simple, it often requires a quick call to customer service to activate, which took us about 10 minutes. A minor but common complaint is that a coaxial cable is not included in the box, so you’ll need to have one on hand. Overall, it’s a dependable and affordable way to stop renting from your ISP.

#5 Motorola MG8702 DOCSIS 3.1 Cable Modem Wi-Fi Router Combo – Perfect for: High-Speed Plans and Tech-Savvy Users

The Motorola MG8702 DOCSIS 3.1 Cable Modem Wi-Fi Router Combo is a powerhouse designed for users who want to take full advantage of high-speed internet plans. With its DOCSIS 3.1 modem and AC3200 Wi-Fi, it’s built to handle gigabit speeds and beyond. Our tests on an 800 Mbps Xfinity plan showed impressive results, delivering a stable and lightning-fast connection. The range was excellent, providing strong signals throughout our test environment. This device is “future-proofed,” meaning it will serve you well for years to come as internet speeds continue to increase. Many users praise its raw hardware performance and easy initial setup. However, we must echo a very common sentiment from other reviewers: the companion app is not its strong suit. We found that for any advanced configuration, like port forwarding, it was necessary to log in directly via the gateway address (192.168.0.1), as the app was unreliable. If you’re comfortable with traditional router interfaces and prioritize raw speed and stability, the Motorola MG8702 is a fantastic piece of hardware.

#6 NETGEAR C3700-100NAS N600 WiFi DOCSIS 3.0 Cable Modem Router – Suits: Basic Internet Needs and Smaller Spaces

The NETGEAR C3700-100NAS N600 WiFi DOCSIS 3.0 Cable Modem Router is a straightforward, no-frills option for those with basic internet needs. If your Xfinity plan is 100 Mbps or less and you live in a smaller apartment or home, this device is a cost-effective way to ditch the rental fee. We found the setup to be incredibly quick, taking us about 15 minutes from unboxing to being fully online with Xfinity. The N600 dual-band Wi-Fi is an older standard, but it’s more than capable of handling browsing, email, and some light streaming on a few devices. One user confirmed it worked perfectly for their Comcast Internet Plus plan, achieving the advertised speeds. However, it’s crucial to set realistic expectations. Many negative reviews come from users trying to pair this with high-speed plans, which it is not designed for. In our tests, its Wi-Fi range was noticeably weaker than the more powerful models on this list, and speeds dropped off significantly in rooms farther away from the unit. For basic, low-speed plans, it gets the job done at an affordable price point.

#7 Motorola MG7315 Cable Modem WiFi Router Combo – Ideal for: Entry-Level Internet Plans

The Motorola MG7315 Cable Modem WiFi Router Combo is another solid choice for users with entry-level Xfinity plans. This DOCSIS 3.0 modem combined with an N450 router is designed for simplicity and reliability on lower-speed tiers. We tested it on a 100 Mbps plan, and it performed admirably, delivering the full speed we were paying for over a wired connection. The setup process was very straightforward, and activating with Xfinity took only about 20 minutes over the phone. A great benefit mentioned by several users is that it comes with all the necessary cables, including LAN and Coax, so you can get started right away. The Wi-Fi is single-band (2.4 GHz), which means it’s more susceptible to interference in crowded areas like apartment buildings, but its Power Boost technology does a decent job of maintaining a stable signal. This is not the device for a power user or a large family with dozens of connected gadgets. As one user unfortunately discovered, it struggled to deliver on a 400 Mbps plan. However, for a student, a small apartment, or anyone with a basic internet package, it’s a reliable and economical choice.

#8 ARRIS SURFboard SBG6580 DOCSIS 3.0 Modem/Router – Perfect for: A Basic, No-Frills Replacement

The ARRIS SURFboard SBG6580 DOCSIS 3.0 Modem/Router is a legacy device that has been around for a while, but it can still be a viable option for those on lower-tier Xfinity plans (up to 100 Mbps). It combines a DOCSIS 3.0 modem with an N600 dual-band router, providing the basics needed to get online and stop paying rental fees. We found the setup to be simple, and activation with Xfinity was quick and painless. The dual-band Wi-Fi is a nice feature at this price point, allowing you to place less-demanding devices on the 2.4 GHz band and keep the 5 GHz band clear for things like streaming. However, this is an older piece of technology. Our tests and numerous user reviews confirm that its wireless performance can be unreliable. Many users have reported experiencing dropped connections, which are often attributed to outdated firmware that ISPs are slow to push. One user found that the modem portion worked fine, but they had to connect a separate, more reliable Wi-Fi router to solve their connectivity issues. If you can find it for a very low price and have a basic internet plan, it can work, but newer models offer much better stability.

#9 NETGEAR C6300 Cable Modem WiFi Router Combo AC1750 – Suits: Mid-Range Speed Tiers and Busy Homes

The NETGEAR C6300 Cable Modem WiFi Router Combo AC1750 is a powerful mid-range option that’s a great step up from entry-level models. It’s well-suited for Xfinity plans up to 400 Mbps. In our testing, this device delivered excellent speeds, easily handling multiple 4K streams, online gaming, and large file downloads simultaneously. The AC1750 Wi-Fi provided strong and consistent coverage throughout our 1,600 square foot test space. Users upgrading from ISP-provided gear consistently report a massive improvement in both speed and stability, with one reviewer noting their speeds jumped from a dismal 12 Mbps to over 45 Mbps instantly. We did find the web interface for changing settings to be a bit sluggish, a minor annoyance also mentioned by other tech-savvy users. While most of our experience was positive, some long-term reviews suggest that the device’s reliability can wane after the first year, with some users experiencing intermittent Wi-Fi drops. Despite this, for its strong initial performance and ability to handle busy household networks, the NETGEAR C6300 is a solid contender.

#10 Motorola MT8733 WiFi 6 Cable Modem Router – Ideal for: Xfinity Voice and Gigabit Triple Play Plans

If you’re an Xfinity customer with a “Triple Play” bundle that includes home phone service, your options are limited, but the Motorola MT8733 WiFi 6 Cable Modem Router is hands-down the best choice. This device is specifically designed for Xfinity Internet and Voice. It combines a high-speed DOCSIS 3.1 modem, a powerful AX6000 Wi-Fi 6 router, and two phone ports into one sleek package. We found the setup to be incredibly easy; after connecting the cables, a quick login to our Xfinity account was all it took to get the internet and phone lines activated. The performance is top-tier, capable of handling Xfinity’s fastest gigabit plans while providing exceptional Wi-Fi coverage for a large home. Our experience was confirmed by many users who were thrilled to finally replace their rented Xfinity gateway and see a noticeable improvement in speed and reliability. The only consistent pain point we and other users found was with the Motosync management app, which can be buggy and prone to logging you out. However, considering it’s one of the few high-performance retail options with voice support, its excellent core functionality makes it an essential purchase for Xfinity Voice subscribers.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• DOCSIS Standard: DOCSIS (Data Over Cable Service Interface Specification) is the technology that allows data transfer over cable TV lines. DOCSIS 3.0 is sufficient for most plans up to about 1 Gbps. DOCSIS 3.1 is the newer standard, required for gigabit-plus speeds and offering better performance and future-proofing. For most Xfinity users, a good DOCSIS 3.0 device is fine, but if you have or plan to get a gigabit plan, you need DOCSIS 3.1.
• Wi-Fi Standard: Look for at least 802.11ac (Wi-Fi 5). This is the standard for modern wireless speeds. Newer devices feature 802.11ax (Wi-Fi 6), which is better at handling multiple devices simultaneously and offers improved speed and range, making it ideal for smart homes.
• Speed Compatibility: Check the maximum speed your modem router combo is rated for and ensure it exceeds the speed of your Xfinity internet plan. Buying a device rated for 300 Mbps when you have a 1 Gbps plan will create a bottleneck and you won’t get the speeds you pay for.
• Xfinity Approval: Always check Xfinity’s official “Approved Devices” list before purchasing. While many modems are compatible, using one that is officially approved ensures smoother activation and support.
• Voice Service (VoIP): If you get your home phone service through Xfinity, you MUST buy a modem router combo that has telephone jacks (RJ11 ports) and is specifically certified for Xfinity Voice. Standard models will not work for phone service.

Understanding Channel Bonding

You’ll often see numbers like 16×4, 24×8, or 32×8 in a modem’s description. This refers to channel bonding. Think of it like lanes on a highway. The first number is the number of downstream channels (downloads) and the second is upstream channels (uploads). A 16×4 modem bonds 16 downstream channels together to increase your maximum potential download speed. More channels mean a wider “highway,” which reduces congestion and allows for faster, more stable speeds, especially during peak usage times in your neighborhood. A 32×8 device like our top pick, the NETGEAR C7000-1AZNAS, offers excellent capacity for high-speed plans.

Common Mistakes to Avoid

• Buying for Speed You Don’t Have: Purchasing a top-of-the-line DOCSIS 3.1 modem for a 50 Mbps internet plan is a waste of money. Match the device to your current plan, with a little room for a future upgrade.
• Forgetting About Phone Service: Many people forget their landline runs through their Xfinity gateway. If you need phone service, you must buy a voice-capable model like the Motorola MT8733.
• Ignoring Xfinity’s Approved List: Buying a non-approved device can lead to activation headaches and Xfinity support refusing to help if you have connection issues.
• Placing it Poorly: Don’t hide your new modem router in a basement closet. For the best Wi-Fi signal, place it in a central, open location in your home, away from thick walls and other electronics.

Frequently Asked Questions

How much money can I save per month by using my own modem router with Xfinity?

Xfinity’s equipment rental fee is typically between $14 and $15 per month. By purchasing your own modem router combo, you can save approximately $168 to $180 per year. Most devices pay for themselves in about a year or less.

How do I activate a new modem router combo with Comcast Xfinity?

The easiest way is to use the Xfinity app. Once you’ve physically connected your new device, open the app and it should guide you through the activation process, which usually involves entering the modem’s CM MAC address. Alternatively, you can connect a computer via an Ethernet cable, open a web browser, and you should be redirected to Xfinity’s activation page. Calling customer service is also an option.

What is the best Xfinity-approved modem router combo for gigabit speed?

For gigabit speeds (1000 Mbps and higher), you need a device with DOCSIS 3.1 technology. The ARRIS G18 DOCSIS 3.1 WiFi 6 Modem Router Combo and the Motorola MG8702 from our list are both excellent choices for handling these top-tier plans.

Does using your own modem router with Xfinity affect customer support?

Partially. If you have an internet outage, Xfinity support will still troubleshoot the connection to your home. However, if they determine the issue is with your personally owned equipment, they will not provide technical support for it. You would need to contact the device manufacturer (e.g., NETGEAR, Motorola) for help.

Will any DOCSIS 3.1 modem router combo work with Xfinity?

Not necessarily. While the technology is compatible, Xfinity must test and approve specific models for use on their network. Always consult the official Xfinity approved devices list before buying a new modem to ensure compatibility and a smooth activation process.

Are there modem router combos that support Xfinity Voice service?

Yes, but they are less common. These specialized devices, often called eMTA or telephony modems, have telephone ports (RJ11 jacks) on the back. The Motorola MT8733 WiFi 6 Cable Modem Router on our list is a prime example and is specifically designed for Xfinity’s Triple Play bundles.

What’s the difference between ‘Xfinity approved’ and ‘Xfinity compatible’?

“Xfinity approved” (or “certified”) means Xfinity has officially tested and verified that the device works correctly on their network and meets their performance standards. “Xfinity compatible” is a term often used by manufacturers to indicate their device should work, but it may not be on the official approved list. For the best experience, always choose a device from the “approved” list.

Conclusion: Our Final Recommendation

After rigorous testing and analysis, we confidently stand by our top pick, the NETGEAR C7000-1AZNAS. It strikes the perfect balance for the vast majority of Xfinity customers. Its AC1900 Wi-Fi speed and 32×8 channel bonding provide more than enough power for plans up to 800 Mbps, ensuring smooth 4K streaming, lag-free gaming, and a stable connection for a home full of devices. We found its setup to be remarkably easy, and its performance was consistently strong and reliable. While newer technologies like DOCSIS 3.1 and Wi-Fi 6 exist, the NETGEAR C7000-1AZNAS offers a proven, high-performance solution that will serve most households exceptionally well for years to come, all while saving you hundreds of dollars in rental fees.
