    Great Modem from ARRIS!!!!

    This modem was exactly what I was looking for and I love the look of it as well as how the lights on the front aren’t super bright either. Runs pretty cool and gets me more than enough speed. I have a 600 MB plan and when doing an Xfinity speed test connected directly to my Linksys router, I actually get over 600 MB with the test. On my phone, I get up to 450 MB with an iPhone 11 Pro, Downloading anything is even faster now and much smoother no matter the file size. Setting up the modem was also relatively easy. At least for me, I was able to set it up through the Xfinity app without having to talk to anybody at all. There are 2 gigabit outputs on the back and the second one you do have to contact xfinity to get it activated. But at the moment, I have enough hook ups with my router so I didn’t bother with that yet. Also I don’t have an actual phone to hook up to it yet, but the phone icon is lit up on it and I have a phone number which it shows through the app, so I’m assuming I’m all ready to go if I want to hook a phone up to it. So it’s nice to know I have that option now if I ever need it. I don’t currently work from home, so I don’t need it at the moment. Definitely recommend though and worth the money. It’s also 3.1 DOCSIS so at least you’ll be set for awhile with this one even if you don’t need it right now. It will get you all the speed you need and comes with 2 VOIP phone jacks and 2 Gigabit ports which is nice.

    So far, so good. Delivering on high speed!!

    Ever since it was installed, there was a big difference in speed over my old router. It has been very solid performer with my Comcast Extreme Pro speed (600 Mbps).

    Fast Speeds!

    Comcast upgraded my Blast! speeds from 200 Mbit to 300 Mbit so I needed a new eMTA. I wanted DOCSIS 3.1, so this was my best option. I am now getting the speeds that are advertised. I had to call Comcast to get it activated, but that didn't take much time. All I had to do was give them the MAC address from the bottom of the modem.

    Difficult to establish service but rock solid

    Difficult to establish Xfinity voice service, does not automatically set up with Xfinity as advertised, but once Comcast finally got it remotely configured with their system, rock solid, reliable, with excellent VOIP voice quality. I highly recommend, but you will have a 30+ minute service outage until Comcast gets it remotely set up. You also have two separate MAC addresses for the device - I apparently gave Comcast the wrong one which delayed my service.
