Motorola MG8702 Review: 3 Weeks Later!

How I tested this Motorola DOCSIS 3.1 cable modem router?

I paired the MG8702 with the Gigabit Internet from Xfinity and used it for various Internet activities throughout the testing period. This allowed me to measure its performance across speeds, coverage, connection handling capacity, wired connectivity, and more.

Now, it’s time to discuss every aspect in detail.

Motorola MG8702 Speed

Motorola MG8702 cable modem boasts the latest DOCSIS 3.1, making it future-proof. It integrates a Wi-Fi 5 router with a combined speed capacity of 3200 Mbps.

Here’s how it gets distributed in dual-band frequency:

2.4 GHz: 1000 Mbps5 GHz: 2167 Mbps
2.4 GHz vs. 5 GHz

To determine the practical speed of Motorola MG8702, I performed a speed test with the Xfinity Gigabit plan.

Motorola MG8702 Speed

At 20 feet distance, it delivered a download and upload speed of 771 Mbps and 38 Mbps, respectively. Upon moving to 40 feet distance, the speed dropped by 30-35%. Coming to numbers, I witnessed 502 Mbps in download and 24 Mbps.

WiFi Coverage & Devices Capacity

The MG8702 claims a WiFi range of 2,000 Sq Ft. This DOCSIS 3.1 cable modem with WiFi router also supports AQM (active queue management), allowing you to minimize latency and streaming lags, making it one of the best options for gaming.

With four internal high-gain antennas, Motorola MG8702’s range in real-world settings is 1,600 sq at max. The signals remained consistent courtesy of dual-band high-power amplifiers, power boost technology, and beamforming support.

And then, there is the smart QoS functionality for efficient traffic prioritization followed by MU-MIMO functionality to connect over 40 devices at once. I had over 26 devices connected, including a smart TV, smartphones, Ring cameras, and more, and none of them faced any lag whatsoever.

Security Features

Motorola makes way for a diagnostic log for you to keep track of your kids through parental controls. Other security features include SPI functionality, attack protection, port filtering, VPN passthrough, and more.

Also, if you plan on using the app frequently, Motorola allows you to access the NAT and bridge mode for additional accessibility. And if you ever plan on using the same as an access point, the DHCP server support and the seamless web interface come in handy.

ISP Compatibility & Plan Suitability

Now that I’ve discussed the most important aspects, it’s time to continue the Motorola AC3200 review by looking at the supported ISPs.

The MG8702 is officially approved and certified to use with Xfinity, Cox, and Spectrum. However, based on several user reviews, they could also pair it with the WOW Internet.

Regardless of the ISP, I recommend using it with 1000 Mbps Internet to make the most of the price you shelled out for the same.


This Motorola DOCSIS 3.1 cable modem router can’t be paired with voice plans as it lacks RJ11 phone ports. If your work setup requires telephone connectivity, check out my list of recommended modems with a phone jack.

Design & Port Setup

Motorola MG8702 Ports

Motorola MG8702 is one of the better-looking modem/router combos, boasting a glossy form factor and a slew of useful LED indicators.

When it comes to the build quality, it is durable enough, characterized by rounded edges and a vertical structure.

The heat-dissipating vents are spacious, keeping the device cool even when it is shouldering the heaviest workloads. From a structural point of view, the product weighs close to 1.8 pounds and measures a manageable 9.5 x 8.8 x 2.8 inches.

In the rear, the MG8702 is replete with four high-speed Gig ethernet ports and one USB 3.0 slot for sharing data over the network.

Also, the LAN ports allow you to plug this modem into smart gaming consoles, helping you cater to their bandwidth-intensive needs.

Hardware Configuration

The DOCSIS 3.1 technology requires further detailing, courtesy of the 2 x 2 OFDM/OFDMA support, making room for thicker 160 MHz channels. This attribute promises better speeds, even during peak hours.

On top of that, the Motorola MG8702 modem also supports 32 x 8 channel bonding technology as a part of its DOCSIS 3.0 backhaul.

Powering this piece of hardware is a standard multi-core processor from Broadcom. Also, you have 512MB of RAM to help the processor quickly cut through the interference.

Adding to the Motorola MG8702 specs are the processor-powered media sharing capabilities, active network management support, and the ability to handle 4K streaming like a pro.

MotoSync App Overview

Installing this combo cannot be any easier, with Motorola making room for the MotoManage application. Also, modem router combos are generally easier to install compared to separate modems and routers.

The featured application has an interactive UI, allowing you to optimize the home network for guests and kids. The app also lets you handle the Quality of Service settings to suit your requirements.

Motorola MG8702 User Reviews

Here’s what users have to say about the MG8702 modem/router:

Finally upgraded my xFi gateway with MG8702 from Motorola and immediately noticed the improvements. It covers areas that were beyond the range of my old device. Satisfied!

Bruce K

Setting up this 2-in-1 device was a piece of cake. Despite being new to all this, with provided instructions, the process was completed within 15-20 minutes. I love app-based management through MotoSync.

Lindsay R

Unlike my previous combo, MG8702’s heat-dissipating vents are much more spacious, so the device remains cool even after shouldering 10 hours of continuous usage.


Walter M

The Motorola app, unlike others, is not up to the mark and lacks many features that are there with Netgear devices. I have got the wrong report regarding my data usage. But feature and performance-wise, the modem-router combo is worth investing.

Natalie K Anderson

Diana A

This is the fastest combo device I have encountered as of now. With the Spectrum Gig plan, I could achieve a maximum of 898 Mbps down and 36 Mbps up speed. Added to that, its AQM tech help reduce latency during intensive activities.

Matthew S

Its compatibility with major cable internet providers in the country ensures I can roam anywhere without any hassle. Performance-wise, it does a great job.

Everly P Sanchez

Monica D

Albeit its decent arrangement of features, it lacks the latest wireless standard, which is expected at this price. You can still experience good speeds, as I can do gaming and streaming.

Michael A

I found the inside of Motorola MG8702 very powerful, with a multi-core Broadcomm processor combined with 512MB RAM that cuts through major interferences and handles any activities like a pro.

Frequently Asked Questions

What is the range of Motorola MG8702?

Per the test and hands-on experiences, the MG8702 can cover a 2,000 Sq Ft area. However, the same can be extended based on the structure of your house.

Does the Motorola MG8702 work with Xfinity?

Motorola MG8702 works well with almost every Xfinity internet plan and bundle. However, I recommend using it with a Gigabit plan. Apart from Xfinity, this device also works well with Cox and Spectrum.

Is the Motorola MG8702 good for gaming?

Yes, MG8702 from Motorola can be a good choice for gaming. The Smart QoS feature prioritizes traffic, and the powerful antennas ensure that even the wireless throughput is reliable.

Is it worth investing in the Motorola MG8702 modem-router combo?

Investing in this device makes sense as it lets you get the best of both worlds — a reliable, future-proof modem and a fast router. Plus, it can be operated using an interactive mobile application.


Although getting a separate modem and a router is more beneficial, setting up and handling two different networking devices could be problematic for some. And this DOCSIS 3.1 modem router combo makes sense, with its performance similar to the standalone units.

And while this router-modem combo has almost every relevant feature aboard, I liked its inventive design and the inclusion of a USB port, which is rare in combo devices.
