Motorola MG8702 XFINITY Modem Router Reviews

The latest release from Motorola in the line of cable modem router combos is the Motorola MG8702. As with most other new releases, the MG8702 is a DOCSIS 3.1 modem. It also features a built-in AC3200 WiFi Router. With that said, it does not feature the newest WiFi 6 (802.11AX) standard. Don’t get me wrong, wireless AC is still pretty sufficient, I’m just unsure why they built it that way. It will, however, handle download speeds up to 6 Gbps.

Motorola MG8702 Overviews

Motorola MG8702 is the best router for Comcast XFINITY service. The Motorola MG8702 has a 2.4GHz IEEE 802.11n wireless access point with a 4-port 10/100/1000 Gigabit Ethernet switch and integrated Cable modem termination system (CMTS). It can be pointed out that if you have a cable modem or DSL modem provided by your ISP, then you do not need to purchase this device as it will just be another wiring clutter on your home network business. If you are using one of these modems, then simply call your ISP and request that they hook up the ethernet port on their device directly into one of the ports of this router thus eliminating the need for an extra modem in your network.

Motorola MG8702 Modem Router is very good looking so it looks like a stylish product. Its design is very simple and perfect for use at home, home office, or small business office. It has four wired Ethernet ports so you can connect to the internet with them, but there is no WIFI 802.11 b/g/n support.

Motorola MG8702 Modem Router can provide a very good signal for your home customers, but not great like DLink DSL 2750U Wireless N300 ADSL2+ Modem Router which can cover more than 26000 sq ft area total.

Pros & Cons


  • It’s a modem router combo, one device that does the job of 2
  • Movies and music streamed smoothly from Netflix or X
  • Box lives with no lags or delays.
  • Many connection options for wired devices


  • Comcast & Motorola would not load up their interface to manage this device on my Mac via USB cable despite repeated calls to Comcast and frequent rebooting of all devices involved. I had to use the web browser interface on my Mac which was much slower.
  • No easy way to disable MAC addresses which can be a security risk since anyone could plug in any computer they wanted and authenticate as a customer of yours if you didn’t have it protected by guest access or other means.


This Motorola MG8702 is great for home usage because it has a very good design and lots of useful features. Also, it provides enough speed or bandwidth for using high-performance computers or laptops without any problems. Please take a look at its customer reviews before buying this product, maybe there are some bad things about this device that may affect its performance. But overall I that this device is the best modem router I’ve ever seen.
