  • Easy to set up. Reliable.
Style: Wifi 5 + DOCSIS 3.1
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. ... show more

  • Easy to set up. Footprint small enough.
Style: Wifi 5 + DOCSIS 3.1
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. ... show more

  • Good Router but App needs Work!
Style: Wifi 5 + DOCSIS 3.1
I purchased this router to replace my Spectrum wifi router so I could have complete control of my setup. The router was a snap to get up and running but I found the app to be intrusive once I started using it. I logged into the main router hub using the IP address to disable the band steering option (since this is the main reason I ditched the spectrum router) and found that whenever you open the phone app it automatically resets all of your changes and re-enables the band steering garbage! You then have to log back in on the IP address and change it back if you want it disabled. Let's face it folks, band steering sucks and it slows down your bandwidth. I use the 5ghz for my 4k television and gaming PC so I can get the most out of my devices. With band steering enabled it lags 4k streaming and kicks off your online gaming session whenever it changes bands! I like the router but I uninstalled the App and only use the IP address method of tuning my system. With that said, I have had a good experience so far with this device. It has great range and hasn't given me any problems so far. ... show more

  • Works with Optimum cable, good speeds, app is not so useful
Style: Wifi 5 + DOCSIS 3.1
I'm on Optimum cable in NJ. Bought this to replace my aging Motorola DOCSIS 3.0 modem/router. This new unit is DOCSIS 3.1, which is .1 better right? Fairly straightforward install, but I spent 25 minutes on the phone with Optimum for them to activate since it's not one of their Arris units. That's not Motorola's fault. I use 3 of the 4 ethernet ports on back. All good. Wireless is strong and was easy to get our laptops, phones, etc hooked up to. Using online speedtest and the slow speedtest on the app, it looks like I'm getting between 215mbps - 229mbps download and 36mbps upload. I'm happy with that. The motosync app is just okay. It's slow. I can get into configs easier from using my browser to the admin backpage. ... show more

  • Stop renting you modem wifi router from Xfinity/Spectrum!
Style: Wifi 5 + DOCSIS 3.0
If you're looking to lower your Xfinity bill month over month - please invest in a modem wif router combo up front. I used to rent my modem from my ISP, but quickly found that after 6 months of ownership of the Motorola MG7700 it has payed for itself. I have great coverage in a large 2 bedroom apt with 2 - 5 devices operating at one time. With install and startup instruction included inside - getting up and running took no more than 15 minutes! ... show more
