For years, I treated my internet service provider’s monthly equipment rental fee as just another unavoidable tax on modern life. That extra $10, $12, sometimes even $15, just vanished from my account every month. It was the price of admission for staying connected. The problem was, the generic, locked-down box they provided was mediocre at best. It offered minimal control, questionable Wi-Fi range, and every time I had an issue, I was at the mercy of their support scripts. The realization finally hit me: over two years, I would pay over $300 for a device I didn’t even own and that barely met my needs. This frustration led me down the path of seeking a modem-router combo I could own outright—a device that could deliver performance, control, and, most importantly, long-term savings. This is a journey familiar to many Xfinity customers, especially those with a bundled voice plan, who often feel locked into limited hardware choices. The search for a reliable, affordable, all-in-one solution is what brought the Amazon Renewed Motorola MT7711 Cable Modem Router squarely onto our testing bench.

What to Consider Before Buying a Modem Router Combo
A Modem Router Combo is more than just an item; it’s a key solution for decluttering your digital life and taking back control of your home network. By integrating a cable modem, a Wi-Fi router, and in some cases, voice-over-IP (VoIP) telephone ports into a single unit, these devices eliminate the need for multiple power bricks, a tangle of Ethernet cables, and separate device management. The primary benefit is financial: you stop paying your Internet Service Provider (ISP) a monthly rental fee, allowing the device to pay for itself over time. Beyond savings, owning your combo unit gives you full administrative access to your network settings, letting you optimize Wi-Fi channels, set up parental controls, and configure security protocols without ISP restrictions.
The ideal customer for this type of product is someone with a cable internet plan who is reasonably comfortable with technology and tired of rental fees. Specifically, for a device like the MT7711, the target user is an Xfinity customer who also subscribes to their Xfinity Voice landline service. This allows them to replace their entire Xfinity gateway with one sleek unit. However, this type of specialized combo isn’t for everyone. If you are a tech enthusiast who demands the absolute latest in Wi-Fi technology (like WiFi 6E or WiFi 7) or wants the flexibility to upgrade your router independently of your modem, a separate modem and router setup would be more suitable. Similarly, if your ISP is not Comcast Xfinity, a model like this one will simply not work, as it’s specifically certified for their network.
Before investing, consider these crucial points in detail:
- ISP Compatibility & Speed Tier: This is the most important factor. You must verify that the modem is approved by your ISP. For the Amazon Renewed Motorola MT7711 Cable Modem Router, it is exclusively for Comcast Xfinity. Furthermore, match the modem’s capabilities to your internet plan. This model, with its DOCSIS 3.0 24×8 channel bonding, is rated for Xfinity plans up to 400 Mbps, making it perfect for many mid-tier plans but insufficient for gigabit subscribers.
- Performance & Wi-Fi Standard: Look at both the modem and router specifications. DOCSIS 3.0 is a robust standard, but DOCSIS 3.1 is necessary for speeds above 1 Gbps. On the Wi-Fi side, AC1900 (WiFi 5) is a strong performer, capable of handling multiple 4K streams and dozens of connected devices. Consider if you need the newer, more efficient WiFi 6 standard for a home filled with the latest smart devices and laptops, as that may require a different model.
- Voice Capability: If you use a landline phone service from your cable provider (like Xfinity Voice), you absolutely need a modem with telephone (VoIP) ports. The MT7711 includes two, making it a true three-in-one solution for Triple Play customers. If you don’t have a voice plan, you can opt for a less expensive model without these ports.
- Condition and Warranty: A “renewed” or “refurbished” product offers significant savings, but comes with trade-offs. While professionally inspected and tested, they may have minor cosmetic blemishes. More importantly, they typically come with a much shorter warranty—in this case, 90 days. You must weigh the upfront savings against the shorter protection period compared to buying a new unit with a one or two-year warranty.
Understanding these factors ensures you select a device that not only saves you money but also perfectly matches your service and performance needs for years to come.

First Impressions: A Sleek and Promising All-in-One Solution
Unboxing the Amazon Renewed Motorola MT7711 Cable Modem Router, the first thing we noticed was its condition. For a “renewed” product, it was immaculate. There were no discernible scuffs or signs of previous use—it truly looked and felt like a new device. Included in the plain brown box were the modem itself, a power adapter, and an Ethernet cable. The unit stands vertically, a design choice we appreciate for its smaller footprint and superior heat dissipation compared to flat-lying models. The black, vented chassis feels sturdy and well-constructed. At 9 inches tall, it’s substantial but not oversized, blending easily into a home office or entertainment center setup.
Flipping it around reveals its impressive connectivity: four Gigabit Ethernet ports for hardwiring demanding devices like gaming consoles and PCs, two telephone ports for Xfinity Voice service, and a coaxial input. The front panel features a clean row of status LEDs that are clear and easy to understand, indicating power, upstream/downstream connection, online status, and Wi-Fi activity without being blindingly bright. Our initial impression is that this is a thoughtfully designed piece of hardware that consolidates three devices into one efficient package. Given its specifications and the attractive price point of the renewed model, it presents an immediate and compelling value proposition for any Xfinity customer looking to escape rental fees.

Deep Dive: Performance, Savings, and Real-World Use
A modem router combo’s worth isn’t determined on the spec sheet, but in the day-to-day grind of streaming, working, gaming, and connecting a household full of smart devices. We put the Amazon Renewed Motorola MT7711 Cable Modem Router through its paces for several weeks, focusing on the core experiences that matter most: the setup process, raw network performance, and the long-term financial benefit.
Activation and Setup: A Surprisingly Painless Transition
The single biggest fear many users have about buying their own modem is the activation process. Stories of endless phone calls and unhelpful support agents are common. We were prepared for a battle, but our experience was refreshingly simple. After physically disconnecting the old rental gateway and connecting the MT7711—plugging in the coaxial cable, power adapter, and an Ethernet cable to a laptop—the device powered on and began its handshake with the network. This part takes about 5-10 minutes as the lights blink and eventually turn solid blue.
Following the included instructions, the next step was a call to Xfinity. We provided the customer service agent with the CM MAC address found on the sticker at the bottom of the unit. The agent quickly located the device on their end, provisioned it for our internet and voice service, and sent a restart signal. This entire phone call took less than 15 minutes. This positive experience was echoed by another user who noted, “Called xfinity and had them update all the information on their side… I had xfinity Remotely restart modem, on their side before start working internet here.” Once Xfinity gives the green light, you can access the router’s configuration utility by typing its IP address (192.168.0.1) into a web browser. The interface is clean and straightforward. We immediately changed the default administrator password, then navigated to the wireless settings to set up our custom Wi-Fi network names (SSIDs) and passwords for both the 2.4 GHz and 5 GHz bands. After saving the settings, the entire network was up and running. It was a remarkably smooth process that should be manageable for anyone comfortable with basic computer tasks. To see its straightforward setup guide is to understand its user-friendly design.
Real-World Performance: Stable Speeds and Solid Wi-Fi Coverage
The Amazon Renewed Motorola MT7711 Cable Modem Router is built around the DOCSIS 3.0 standard with 24×8 channel bonding. In plain English, this means it uses 24 downstream channels to download data and 8 upstream channels to upload it. This technology provides a robust and congestion-resistant pipeline for internet plans up to a recommended 400 Mbps. On our 300 Mbps Xfinity plan, the results were excellent. Wired speed tests consistently hit 340-350 Mbps down and 20-25 Mbps up, exceeding the advertised speeds of our plan. The connection was rock-solid, with no random disconnects or slowdowns during our testing period.
Wi-Fi performance, powered by the AC1900 standard, was equally impressive for a device in this class. The “AC” means it uses the WiFi 5 standard, and “1900” represents the combined theoretical speeds of its 2.4 GHz and 5 GHz bands. In our 1,800-square-foot home, coverage was comprehensive. The 5 GHz band provided blistering speeds in the same room as the router, perfect for our 4K streaming box and work laptops. The 2.4 GHz band, while slower, offered better penetration through walls, ensuring all our smart home devices (thermostat, smart plugs, cameras) in the far corners of the house maintained a stable connection. Motorola credits this range to its Power Boost technology and AnyBeam beamforming, which actively focuses the Wi-Fi signal toward connected devices rather than broadcasting it equally in all directions. For a family with multiple streamers, a remote worker, and a dozen smart gadgets, the MT7711 handled the load without breaking a sweat. We did note, as one user insightfully pointed out, that the 5 GHz settings lack some of the higher DFS channels (100-144). While not an issue for most, users in extremely congested Wi-Fi environments like dense apartment buildings might miss this advanced configuration option for finding clearer airspace.
The Xfinity Voice and Cost-Saving Equation
The feature that truly sets the Amazon Renewed Motorola MT7711 Cable Modem Router apart is its integration of two phone ports specifically for Xfinity Voice. For customers on Xfinity’s Triple Play bundles, this is the holy grail. It allows you to completely eliminate the Xfinity gateway and its associated rental fee while keeping your landline service. We plugged a standard cordless phone base into the Tel 1 port, and it worked instantly after activation. Call quality was crystal clear, indistinguishable from the service provided by the rented equipment.
This is where the financial argument becomes undeniable. Let’s assume an average rental fee of $14 per month. Over one year, that’s $168. The renewed MT7711 often sells for a price that allows it to pay for itself in just 6-8 months. Every month after that is pure savings directly back in your pocket. This is the single most compelling reason to invest in this cost-saving device. However, it’s crucial to acknowledge the “renewed” aspect. The 90-day warranty is significantly shorter than the 1-2 year warranty on new products. We encountered one alarming user report of a power supply failure. While this seems to be an outlier and is covered by the renewed guarantee’s replacement policy, it serves as a reminder of the small risk associated with pre-owned electronics. For most, the substantial cost savings will heavily outweigh this minimal risk.
What Other Users Are Saying
Scouring feedback from other users, we found a consensus that largely mirrors our own positive experience. Many, like the user who simply stated, “Hasta ahora me está dando buen servicio” (“So far it’s giving me good service”), are pleased with the stable, set-it-and-forget-it nature of the device. The most detailed positive feedback often centers on the easy setup process, with one user laying out their step-by-step success story of calling Xfinity, configuring the router’s IP address, and getting everything running smoothly, concluding they were “Very very pleased.”
However, the feedback isn’t universally perfect. The most significant critique we found, aside from the rare but serious hardware failure report of an “exploded” power supply, was a technical one regarding advanced settings. A power user noted that the 5 GHz Wi-Fi band was missing channels 100-144, which can be useful for avoiding interference in crowded areas. While this won’t affect the average user, it’s a valid point for those who like to fine-tune their network. These reviews paint a clear picture: the Amazon Renewed Motorola MT7711 Cable Modem Router is a fantastic, reliable workhorse for the vast majority of Xfinity users, with some limitations for advanced network tweakers.
How Does the MT7711 Compare to the Alternatives?
While the Amazon Renewed Motorola MT7711 Cable Modem Router excels in its niche, it’s important to see how it stacks up against other popular models, especially for users with different needs or internet providers. Here’s a look at three key competitors.
1. NETGEAR Nighthawk C7100V Cable Modem WiFi Router Combo
- Compatible with Xfinity Cable & Voice Plans up to 600Mbps speed.
- Three-in-one DOCSIS 3.0 Cable Modem + AC1900 WiFi Router+ Xfinity Voice and 2 USB ports
The NETGEAR Nighthawk C7100V is the most direct competitor to the Motorola MT7711. It shares many core features: DOCSIS 3.0 with 24×8 channel bonding, AC1900 Wi-Fi, and two voice ports for Xfinity. The key difference is its rated speed capability, supporting Xfinity plans up to 600 Mbps, a step up from the MT7711’s 400 Mbps ceiling. If you have an Xfinity plan between 400 and 600 Mbps and require voice service, the C7100V is the superior choice. For users with plans of 400 Mbps or less, the choice comes down to price and brand preference, as both will perform admirably. The MT7711, especially in its renewed state, often presents a better value.
2. NETGEAR Nighthawk CAX30 WiFi 6 Cable Modem Router
- Compatible with major cable internet providers including Xfinity, Spectrum, Cox and more. NOT compatible with Verizon, AT and T, CenturyLink, DSL...
- Coverage up to 2,000 sq. ft. and 25 concurrent devices with dual-band WiFi 6 (AX2700) speed (up to 2.7Gbps)
The Nighthawk CAX30 represents a significant technological leap forward. It features the newer DOCSIS 3.1 standard, making it capable of handling multi-gigabit speeds, and WiFi 6 (AX2700), which is more efficient at managing dozens of connected devices than the WiFi 5 found in the MT7711. Crucially, it lacks voice ports, so it is not an option for Xfinity Triple Play customers who want to keep their landline. This model is ideal for users on faster-tier plans (gigabit and above) from a wider range of ISPs (including Spectrum and Cox) who prioritize future-proofing and the latest Wi-Fi standard over voice capability. It’s built for a different, more performance-focused user.
3. NETGEAR Nighthawk CAX80 Cable Modem WiFi 6 Router Combo
- Compatible with major cable internet providers including Xfinity, Spectrum, Cox and more. NOT compatible with Verizon, AT&T, CenturyLink, DSL providers,...
- Coverage up to 2,500 sq. ft. and 30 concurrent devices with dual-band WiFi 6 (AX6000) speed (up to 6Gbps)
The Nighthawk CAX80 is a top-of-the-line beast. Like the CAX30, it uses the future-proof DOCSIS 3.1 standard, but it pairs it with incredibly fast AX6000 WiFi 6. This device is designed for enthusiasts, serious gamers, and households with gigabit-plus internet plans and a massive number of high-bandwidth devices. It offers performance that the MT7711 simply cannot match. However, it comes at a premium price and, like the CAX30, does not include voice ports. This is overkill for the average user but is the correct choice for those who demand the absolute best performance and have a budget to match. When considering this option, remember to check out the incredible value of the MT7711 for more modest needs.
Our Final Verdict: Is the Amazon Renewed Motorola MT7711 Worth It?
After extensive testing and analysis, our verdict is clear: the Amazon Renewed Motorola MT7711 Cable Modem Router is an absolutely outstanding value proposition for a very specific but large group of people. If you are a Comcast Xfinity customer with an internet plan of 400 Mbps or less, and you subscribe to Xfinity Voice service, this device is arguably the smartest tech purchase you can make. It delivers reliable speed, good Wi-Fi coverage, and the all-important voice capability in a single, easy-to-manage unit. Its ability to pay for itself in under a year by eliminating rental fees is a powerful financial incentive that is hard to ignore.
The caveats, while important, are manageable. Its exclusivity to the Xfinity network is a limitation by design, not a flaw. The primary consideration is its “renewed” status, which brings a shorter 90-day warranty. However, this is balanced by a significantly lower entry price and a reliable guarantee for that initial period. For the budget-conscious Xfinity Triple Play customer looking to break free from endless fees without sacrificing performance, this device is a home run. If you fit this profile, we wholeheartedly recommend you check the latest price and make the switch today. The long-term savings start now.
