Xfinity (Comcast) sent me a message saying my old modem was too old to receive the higher speed signal that my plan demands. So I needed to upgrade and choose this Motorola MG8702 because I wanted to buy something instead of renting to save money in the long run. It pays for itself in about 1.5 years or so. Installation was easy and so was setting up this device. Really easy actually. And I didn't need to call Comcast and sit on hold forever. After you plug it in and connect with an Ethernet cable, I was able to use the free Xfinity app to register my device with Comcast - just follow the steps and it only took a few minutes. Once Xfinity acknowledged my new device, it automatically registered this unit to my account and started to get the faster speed almost immediately. Then, in combination with the free Motosync app, I was able to adjust the settings of the modem with ease. You can also tap into these settings if hardwired to a PC but having the option to use the app from anywhere is very convenient and easy. I was able to rename and assign the username and password of my old unit to this new one using the app so I didn't need to re-sync all my connected devices which was very time saving. If you buy this device, go ahead and install this Motosync app to your phone now as you wait for it to arrive to save time later. You will need it. Also, between the Xfinity app and this Motosync app, the unit was smart enough to automatically install the latest firmware. Granted, my unit did get hung up once while installing the new firmware but everything went through after one restart. Other than this tiny hiccup, I have no complaints. Been using this for a couple months now and has been reliable. Have not needed to restart it since. This model also has a USB port which is mainly used for diagnostics but it can also be used to charge a USB powered device in a pinch; this is a nice, simple extra. I guess my only complain is a very minor one - the 4 Ethernet ports on the back are aligned in a 2x2 square configuration. I would have preferred a 4-in-a-row vertical stack as I think accessing the ports are little easier that way but this is very minor and doesn't really make a difference. Recommended.

This review is for MOTOROLA MG8702, DOCSIS 3.1 cable modem. I suggest other reviewers to mention their device model info too in the reviews since AMAZON mix up all different devices feedback causing confusion. Installed with XFINITY on Dec 29th, 2020 replacing rental modem with their Agent on phone with me. This is approved modem on their list. Registration and MAC address activation steps performed by XFINITY went smooth they noticed no issue at their end, however the modem at my end kept on recycling couple of times (LEDS getting turned on, blinking etc.) before getting stable, however even after 15 minutes of wait the connection to internet did not get through. All i was getting was XFINITY home page with message to download their application and a click to continue voice activation. As XFINITY agent had no clue on next steps, i started clicking on voice activation link at my browser (My laptop was connected to ethernet port of this modem). XFINITY page prompted for email address, phone verification and sent me OTP code over phone and volla internet started. I shared above since Agent helping me to activate had no clue and was lost on why this step was required. All is good now. Signal strength all over the house is amazaing. Speed test over wifi is showing 80MBPS down, 7 MBPS uplink though uplink seems slower on speed test however i am not seeing any issue in my day to day use. My package is 200MBPS with xfinity

I bought this modem router combo 4 years ago and it worked great up until about February of this year (2026). It relies on the Motosync app to customize and troubleshoot entirely (not buying a modem with this feature ever again). In February of this year all users were forced to upgrade to the Motosync+ app, which was incredibly clunky and often crashed. Fast forward to June of this year and suddenly no one can log in, a little wheel just spins. But the modem was still usable at least. I kept trying from time to time to see if it worked and went to try today only to find it still didn’t work and now Motosync+ is unavailable on the Apple App Store in my region… I tried downloading the old Motosync app, which was still available, but it won’t let you log in. Motorola has effectively bricked all of their modems with this move and has never responded to any customers regarding it. Do not buy this modem or any other Motorola modem, they are essentially paperweights.

I originally had an Arris Surfboard (north of $300) and only lasted 2 years before giving me connectivity issues. I ended up replacing it with a Motorola 7550 Gateway. The 7550 lasted me 5 years and was less than $300, Arris never again. So I finally began having connectivity issues. Constantly needed to remove and reconnect the power cable and frequent factory resets allowed a few more months on the 7550. Finally I decided I needed to replace it. Now I originally shopped around, looking at other brands. Then I figured 5 years was quite the run with the amount usage the family and I put it through. So I stayed with Motorola and got the MG8702. I need four ethernet ports. So I couldn't get anything smaller. Above that, I had a $130 amazon gift card, so spending less than $150 out of pocket for it was a no brainer. So far so good. Set up was just about plug and play. Did have to call my ISP to commission the new hardware to be seen on the network. Twenty minutes later and I was back up and running. Connections stay strong for as far outside as I usually end up (roughly 50' away from the gateway, with multiple walls between us). I have many devices connected (tablets, tvs, phones and gaming systems) and I haven't came across any issues with slow down. Highly recommend if you're trying to save money long term instead of renting a modem from your ISP then having to purchase a router after the fact. This gateway (modem/router combo) stands up vertical. It does stand taller then the 7550 it replaced, but not by much. I didn't setup using the phone app. I just used my desktop hardwired to the gateway to setup SSID and update password.

I purchased this Wi-Fi Router to replace my old one after receiving a television set for my birthday. (The old router was only 2.4ghz and the tv needed 5ghz Wifi.) The router was fairly simple to install and it was complete in just a few minutes. However, getting it to sync with Xfinity? That was a bit of a journey. Be prepared to speak with someone on the phone because logging in is a nightmare. From sending a code that you don’t receive, to sending you back to the log in over and over they really need to upgrade their web design. Once I got past that, everything worked great. This modem/router has an app you download. It will load all your household appliances (stove, doorbell, phones, laptops, printers, etc). you have running or offline. The issue here is figuring out which is which. Even though I am quite capable with technology, it took a while to get to know and name them. One thing I really like about this router is its ability to recognize malware on sites you visit and shut them down. There is a newer version of this router now, but this one will fulfill all my tech needs for a few years.

Tengo una semana con este modem motorola 8702. Hasta ahorita cumple con lo que promete. Tengo el paquete de 1 GB de velocidad... y me da al rededor 945 gbs/s de bajada 37 gbs/s de subida... con el wifi al rededor de 400 gbs de bajada y de subida 37 o 33. Que para mi gusto es muy aceptable. Tenia el temor que no fuera ser compatible con la compañía optimum (Ya que no es el primer modem que me compro y eh tenido problemas de compatibilidad con el modem anterior.) Pero con este modem fue rapido y facil de activar... A un que si les doy unos consejo: 1- Antes se llamar a su proveedor les recomiendo que le agan la configuración a su modem (eso es entrar a su modem desde usuario de admin y cambiar el usuario y contraseña, que tiene por defecto.) Ya teniendo el modem configurado, ahora si llamar a su proveedor de internet. 2 Ya con proveedor, despues de dar su numero MAC y despues de hacer todo el proceso para activar el modem (y que notes que estas recibiendo la señal) Sin colar con tu proveedor revisa en una pag de "test de velocidad de internet" cuanta velocidad te esta llegando realmente. Si te esta llegando menos de lo que esperas, reinicia tu modem o dile a tu proveedor que reinicie la señal por ti. Es casi seguro que eso va establecer la velocidad que tienes en tu contrato. El unico punto negativo que tiene este modem, es que tiene el wifi 5g y el modem de la marca que tiene el 6g es muy caro...pero bueno en general es un excelente modem hasta ahora. Espero no cambiar de opinión en un futuro.

We just got this combination modem/router hooked up. Was easy to switch from older Motorola model to this one. Once it was connected to Xfinity and updated to my account via their customer service chat it was up and running and what a difference in speed, this thing was fast. Of course, it required us upgrading our service, Xfinity always looking to get more of your $$ but so far, running well. Can't speak to longevity and stability yet.
