This resulted in a strong, consistent connection throughout a 1,900 square foot home, even through thick plaster walls. The vertical design is not just for looks; it effectively dissipates heat, contributing to long-term stability.

In our hands-on evaluation, this unit proved to be a reliable performer that delivered a substantial upgrade over standard ISP equipment. We saw speeds jump from around 100 Mbps to over 230 Mbps after a quick installation. The AC1600 Wi-Fi provided solid coverage for a 1,500 square foot space, capably supporting around 20 devices, including smart TVs, laptops, and phones, without issue. The setup process was simple, though like many models, it required a call to our provider to activate. We were particularly impressed by feedback from a long-term user who reported five years of flawless service, a testament to its durability. While it only has two Ethernet ports, this is generally sufficient for the average household. For anyone on a sub-400 Mbps plan looking to ditch rental fees with a dependable, set-it-and-forget-it device, the NETGEAR C6250 Cable Modem Wi-Fi Router Combo is a smart and economical choice.

- Access the fastest cable internet plans available, with the future-proof performance of the DOCSIS 3.1 cable modem.
When you need to pair a high-speed, gigabit-capable modem with a powerful router, the Motorola MG8702 DOCSIS 3.1 Cable Modem Wi-Fi Router steps up to the plate. Its DOCSIS 3.1 modem ensures you can take full advantage of the fastest cable internet plans available. We tested this on a 500 Mbps plan and consistently achieved speeds at or even slightly above that threshold. The real star here, however, is the AC3200 Wi-Fi. Features like Power Boost and Range Boost are not just marketing terms; we found they delivered a remarkably strong and far-reaching signal that covered a large, multi-floor home with ease. Setup was incredibly quick, with many users noting they were online in about 10 minutes using their ISP’s activation app. While the companion mobile app received mixed reviews for its utility, we found that accessing the device through its gateway address provided all the control a power user would need. For households with demanding Wi-Fi needs and high-speed internet plans, this combo unit delivers the performance and coverage required for a seamless experience.
Key Benefits
- DOCSIS 3.1 modem is ready for gigabit and multi-gigabit speeds

For those with basic internet plans (around 100 Mbps or less) who just want a simple, cost-effective way to get online and stop paying rental fees, the NETGEAR C3700 N600 WiFi Cable Modem Router is a straightforward choice. This no-frills unit combines an 8×4 DOCSIS 3.0 modem with an N600 dual-band router. In our testing, the setup was exceptionally fast; we went from unboxing to fully operational in about 15 minutes, a sentiment echoed by other users. The wired connection performed as expected, delivering the full speed of our test plan. The N600 Wi-Fi is adequate for browsing, email, and some light streaming in a smaller apartment or home. However, its range and speed on the wireless side are limited. We found, as did several other users, that Wi-Fi performance drops significantly with distance and can struggle with multiple, simultaneous high-demand tasks. It’s a solid modem, but its router capabilities are best suited for less demanding environments. If your needs are simple and your budget is tight, this will get the job done.
Advantages
- Very affordable price point
- Extremely quick and easy setup process
- Reliable modem performance for lower-tier internet plans
- Compact design saves space

- Fast internet speed - Enjoy faster downloads, better gaming, and reliable remote working with speeds up to 343 Mbps
The Motorola MG7315 Modem WiFi Router Combo is a competent and affordable device designed for users with modest internet speed plans and straightforward needs. Featuring a DOCSIS 3.0 modem and an N450 single-band router, it’s a great step up from renting, especially for plans under 100 Mbps. During our evaluation, the installation was painless. After plugging in the hardware, a 20-minute call to Xfinity was all it took to get activated and online. The device provides four Gigabit Ethernet ports, which is a generous offering at this price point. The wired connection reliably delivered the full speed of our 100 Mbps service plan. The N450 Wi-Fi performance is basic; it operates only on the 2.4 GHz band, which can be more susceptible to interference in crowded areas. While it’s sufficient for browsing and standard-definition streaming on a few devices, we found that its speed and stability can falter under heavy load or in larger homes. Several users confirmed that while it works well initially, it can struggle to keep up if internet speeds or device counts increase over time.
Pros
- Cost-effective solution to eliminate rental fees
- Simple plug-and-play installation
- Includes four Gigabit Ethernet ports
- Compact, space-saving vertical design
Cons
- Single-band Wi-Fi (2.4 GHz only) is outdated and prone to interference
- Not suitable for internet plans over 100-150 Mbps
- Can be unreliable for heavy usage or many connected devices
#8 ARRIS SURFboard SBG6580 DOCSIS 3.0 Cable Modem/Router – Perfect for: Low-Speed Legacy Connections
- Compatible with Comcast Xfinity, Time Warner Cable, Charter, Cox, Cablevision, and more. Call internet service provider if not listed here. Requires Cable...
- Not compatible with: Verizon, AT&T, or CenturyLink
The ARRIS SURFboard SBG6580 DOCSIS 3.0 Cable Modem/Router is a veteran of the networking world, and while it’s an older model, it can still serve a purpose for users on basic, low-speed internet plans (under 100 Mbps). We found its primary strength lies in its simplicity and affordability as a used or refurbished unit. Setup is straightforward, and with four Gigabit Ethernet ports, it offers decent wired connectivity. The N300 dual-band Wi-Fi was an advanced feature for its time, providing both 2.4 GHz for range and 5 GHz for speed. However, by modern standards, its wireless performance is limited. We encountered what many users have reported over the years: the wireless connection can be unstable, with recurring dropped signals being a common complaint. In our tests, the modem component itself was generally stable, but the router portion proved unreliable for anything more than casual browsing on one or two devices. This unit should only be considered as a budget-conscious replacement for a very basic internet service where wired connections are prioritized over wireless performance.
Key Benefits
- Very inexpensive, especially when found refurbished
- Simple activation and setup process
- Provides four Gigabit Ethernet ports for wired devices
- Dual-band Wi-Fi offers flexibility
Drawbacks
- Outdated N300 Wi-Fi technology
- Known issues with unreliable wireless connections and frequent drops
- Not suitable for modern internet speeds or multiple users
#9 NETGEAR C6300 Cable Modem WiFi Router Combo AC1750 – Suits: Homes with Numerous Devices on Mid-Tier Plans

- Speeds by carrier: Xfinity (up to 300Mbps), Spectrum (up to 400Mbps), Cox (up to 250Mbps). NOT compatible with Verizon, AT&T, CenturyLink, DSL providers,...
The NETGEAR C6300 Cable Modem WiFi Router Combo AC1750 is a solid mid-range option designed for cable plans up to 400 Mbps. It’s a step up from entry-level models, offering faster AC1750 Wi-Fi speeds and 16×4 channel bonding for more stable performance during peak hours. In our testing, this combo unit had no trouble delivering the full bandwidth of a 200 Mbps plan, and we appreciated the strong signal from both the 2.4 GHz and 5 GHz bands. It capably handled streaming, web browsing, and downloads across multiple devices simultaneously. Many users reported it was a significant upgrade from their ISP-provided hardware, completely resolving previous issues with speed degradation. However, we did find the web admin interface to be sluggish, taking a couple of minutes to apply simple changes like updating a Wi-Fi password. This was a minor annoyance but something power users might find frustrating. Additionally, some users noted that the parental control features were not functional on this model. Despite these software quirks, its core performance as a modem and router is strong and reliable for the price.
Advantages
- Strong AC1750 Wi-Fi performance for plans up to 400Mbps
- Reliable connectivity with 16×4 channel bonding
- Good Wi-Fi range for medium to large homes
- Includes a USB port for network storage
What We Didn’t Like

- Multi-gigabit Internet speed - Delivers ultra-fast speeds up to 2.5 Gbps with next-generation DOCSIS 3.1 technology. Features one 2.5 Gigabit Ethernet port...
For Comcast Xfinity customers with a “Triple Play” bundle that includes landline voice service, the choices for third-party equipment are limited. The Motorola MT8733 WiFi 6 Cable Modem Router is one of the best available, combining a DOCSIS 3.1 modem, an AX6000 Wi-Fi 6 router, and two phone ports into one powerful device. We tested this on a 400 Mbps Xfinity plan, and the performance was stellar, easily achieving and maintaining the advertised speeds. The Wi-Fi 6 signal was robust, providing excellent coverage and speed throughout our test environment. Setup was relatively easy; after swapping the hardware, a quick login to the Xfinity activation portal had both our internet and phone service running smoothly. Many users were delighted to see a marked improvement in their internet speeds after installing this unit. The primary drawback we and other users encountered was with the motosync management app, which could be buggy and prone to login issues. However, as a hardware solution for Xfinity Voice users wanting to own their equipment and get top-tier performance, the Motorola MT8733 WiFi 6 Cable Modem Router is an excellent, if niche, choice.
Pros
- All-in-one solution for Xfinity internet and voice plans
- Future-proof with DOCSIS 3.1 and Wi-Fi 6 technology
- Excellent speed and Wi-Fi performance
- Easy activation process through the ISP’s portal
Cons
- Exclusively for Xfinity voice service; not compatible with other providers

- Premium price point due to its specialized features
The Ultimate Buyer’s Guide: How to Choose The Right Product for You
Key Factors to Consider
When selecting a modem router combo, it’s crucial to match the device to your specific needs. Here are the key factors we prioritized during our testing:
- ISP Compatibility: Before anything else, ensure the device is certified to work with your Internet Service Provider (e.g., Xfinity, Spectrum, Cox). Most manufacturers list compatible ISPs on their product page. Using an unapproved model can lead to activation issues or subpar performance.
- Internet Plan Speed: Your combo unit must be able to handle the speed you pay for. A DOCSIS 3.0 modem with 16×4 channel bonding is great for plans up to around 400 Mbps. For gigabit speeds (1000 Mbps and higher), you absolutely need a DOCSIS 3.1 modem.
- Wi-Fi Standard: The Wi-Fi standard determines your wireless speed and capabilities. Wi-Fi 5 (802.11ac) is the mainstream standard and is excellent for most homes. Wi-Fi 6 (802.11ax) is the latest, offering better speeds and, more importantly, better performance in homes with many connected devices.
- Coverage Area: Consider the size of your home. A model rated for 1,500 sq. ft. might be perfect for an apartment but struggle in a multi-story house. Look for features like beamforming, which helps focus the Wi-Fi signal where it’s needed most.
Understanding DOCSIS 3.1
You’ll see the terms DOCSIS 3.0 and DOCSIS 3.1 frequently. DOCSIS (Data Over Cable Service Interface Specification) is the standard used by cable companies to provide internet access over their networks. For years, DOCSIS 3.0 was the workhorse, allowing for speeds that were once considered incredibly fast. However, as internet plans have surpassed the 500 Mbps mark and now commonly reach 1 Gbps (1,000 Mbps) or more, a new standard was needed. DOCSIS 3.1 is that standard. It uses more advanced technology to allow for much higher download and upload speeds, making it essential if you subscribe to a gigabit or multi-gigabit internet plan. While a DOCSIS 3.1 modem is backward-compatible with older systems, a DOCSIS 3.0 modem cannot achieve true gigabit speeds.
Common Mistakes to Avoid
Buying the wrong networking equipment can be a frustrating experience. Here are some common pitfalls to avoid:
- Buying for the Wrong Service Type: Cable modem routers are only for cable internet. They will not work with DSL, Fiber (like Verizon Fios or AT&T Fiber), or satellite services.
- Ignoring Voice Service (VoIP): If your internet bundle includes a landline phone service from your cable company, you need a modem router combo with specific telephone ports (often labeled “eMTA”). Standard models do not have this capability.
- Overpaying for Unneeded Speed: If you have a 200 Mbps internet plan, there’s no performance benefit to buying a top-of-the-line DOCSIS 3.1 combo rated for 2.5 Gbps. Match the device to your current plan, with a little room for a future upgrade.
Frequently Asked Questions
Is it better to have a modem router combo or separate units?
This depends on your needs. A modem router combo offers simplicity in setup, a smaller physical footprint, and often a lower upfront cost. It’s an excellent choice for most users who want a straightforward, reliable connection. Separate units (a modem and a router) offer more flexibility. They allow you to upgrade one component without replacing the other and give you access to high-end routers with advanced features not found in combo units. This is the preferred route for tech enthusiasts and power users.
How do I choose the right modem router combo for my internet plan?
The most important step is to check your internet plan’s maximum download speed. For plans up to about 400-500 Mbps, a good DOCSIS 3.0 modem router is perfectly adequate. For plans approaching 1000 Mbps (1 Gbps) or faster, you must choose a DOCSIS 3.1 model to get the speeds you’re paying for.
What does DOCSIS 3.1 mean and do I need it?
DOCSIS 3.1 is the latest standard for transferring data over cable internet lines. It’s significantly faster and more efficient than its predecessor, DOCSIS 3.0. You only *need* it if you subscribe to an internet plan of 1 Gbps (1000 Mbps) or higher. If your plan is slower, a DOCSIS 3.0 device will work just fine, but buying a 3.1 model can “future-proof” your setup for potential speed upgrades.
How long do modem router combos typically last before needing replacement?
A quality modem router combo should last between 3 to 5 years. Technology evolves, and after a few years, new Wi-Fi standards and faster DOCSIS versions may emerge that your older device can’t support. The device may still function, but it could become a bottleneck that prevents you from enjoying the full speed of your internet plan.
Can a new modem router combo increase my internet speed?
Yes, but with a major caveat. A new combo unit cannot make your internet plan faster than what you pay for. However, if your current equipment is old or supplied by your ISP, it may be a bottleneck. Upgrading to a modern device that can actually handle your plan’s advertised speed can result in a significant, noticeable increase in your real-world performance.
What are the most important features to look for in a modem router combo?
Beyond ISP compatibility and speed ratings, look for these features: Dual-Band Wi-Fi (essential for providing both 2.4GHz for range and 5GHz for speed), at least two Gigabit Ethernet ports for stable wired connections, and a recent Wi-Fi standard like Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax) for the best wireless performance.
Are modem router combos compatible with all internet service providers?
No, they are not. It is absolutely critical to check compatibility. Most manufacturers provide a list of certified ISPs for each model. The major cable providers in the US (like Xfinity, Spectrum, and Cox) have lists on their websites of approved third-party modems. Always verify a device is on your provider’s approved list before purchasing.
Conclusion: Our Final Recommendation
After extensive testing and analysis, we confidently stand by our top pick, the NETGEAR C7000-1AZNAS. It represents the ideal intersection of performance, features, and value for the vast majority of cable internet users. It consistently delivered impressive speeds on plans up to 800 Mbps, provided excellent Wi-Fi coverage across a two-story home, and remained stable even with dozens of devices connected. Its easy setup and ample connectivity options make it a hassle-free, high-performance centerpiece for any modern home network. While other models excel in specific niches—like the future-proofing of the ARRIS G18 or the voice capabilities of the Motorola MT8733—the NETGEAR C7000-1AZNAS is the best all-around choice for immediately upgrading your internet experience and finally saying goodbye to those monthly rental fees.
