Customer Ratings & Reviews

Amazing speed and connection. I couldn’t be happier with my purchase!

Comcast upgraded my service, requiring some kind of better/faster/newer moden-router. This one has been great! Not getting near as many disconnections from XBox multiplayer events. Biggest surprise was how easy to configure using online tools from both Arris and Comcast.

unit is going strong and is super fast. I hooked this baby up and got it connected to the service provider and its been amazing. No dropped signals anywhere in my house and the speed is incredible.

If there is a 0 star for rating, I will do that. This is the worst modem + router I ever bought in my life. I bought this because of recommendation from my ISP website. At first I was thinking issue is with my ISP, after troubleshooting with them several times and even working their field technician, I finally found out the WiFi from this product is very unstable. By the time solution was found, I'm not eligible to return this 200+ dollar garbage product. Now I'm stuck with it. Solution: I ended up have to turn off the WiFi capability of this modem and combine this modem with another router to make it stable. Arris app also the worst app for any modem/router app. I used TP-Link and Asus before, and they update connected device properly while Arris app, well you need to wait for 10 minutes or more before you can see connected device is updated. When you setup this modem using Arris app, you need to be careful and not to enter wrong information. There is no back button after it complain an incorrect value in the next page. I have to uninstall app and start over just because of this. I ended up deleting Arris app and never use it and using the web UI instead. Don't buy!

This is the easiest way to get 2.5gb connection to your pc. Because it is a modem/router combo, the 2.5gb lan out will not bottleneck your 1gb isp connection. It has been stable. The web gui leaves a lot to be desired, and don’t even bother with the app.

Great modem but like I found out later setup was a pain. I had to have Comcast come get it to connect. They did find some issues at the pole but their customer support is horrible. I do have to reboot it at least once a week to keep a fast connection.

This was a good buy and worked well with our system.

Great modem but a little expensive. You get what you pay for.

I switched to my own modem/router years ago. I had a great Motorola but I needed to upgrade due to increased speeds. I purchased this because most of the reviews were promising, but NOPE. This thing is horrible. It worked ok for a few days but then the service started dropping, multiple times a day. It was not on Xfinity’s end, it was definitely this modem. I had to constantly reset the modem and it was interrupting everything including my work as I work from home. I did many factory resets per troubleshooting guidelines and it just did the same thing. Luckily I had an extended return period due to the holidays. Done messing with this piece of junk and it’s going back- don’t waste your money. Came back here to read the one star reviews and it appears this is a frequent problem! For $300+ you can buy a better modem. I replaced this with an upgraded Motorola modem and it has been working flawlessly. Thankful I can get my money back for this junk.

Great modem and one of the fastest combo modems with the new 3.1 rating

Best gateway ive bought. The Ipv6 runs great, and all my electronics on it are way faster. Did take a little to set it up.

Blazing fast, easy to setup and worth every penny.

Upgraded to this modem and router several months back when having issues with the speed in our home with the provider we use. This model works great. We've had no issues.

This modem took our wifi speed from 400 mbps to over 900. Even though our other modem was equipped to handle up to 6 to 700 mbps it came nowhere near that. I am extremely happy with this modem.

Excellent product. Phone app isn’t very helpful and I resorted to manual setup. Remember to change the security encryption settings on the router to match your various devices or they won’t connect. That stumped me for a bit. Again it’s the setup not the product that can be awkward.

Works Great. I had issues with speed and bought this to try and fix which it did. However I just canceled cable, but it worked great.

Upgraded to 3.1 docsis with this unit. Had motorola router that outlived its usefulness. This router has greater capabilities with updated current industry standards.

Easy setup and great performance. Highly recommended!!

Comcast said my old one needed to be replaced. I was excited for this one. Once I installed it, it was just ok. It drops wifi more often then I expected. I wish the app had a few more features like being able to open up ports easily.

I upgraded from an Xfinity Gateway and I am extremely pleased so far. Speeds are as they should be. I am no longer limited in my options. I was able to fix a crashing issue with multiplayer games, due to Xfinity not allowing me to change my DNS server.
