Customer Ratings & Reviews

Great product, no need for the mesh extender’s because it covers 2500 sqft and that’s great for me. Ready to use out the box. I just called my service provider. Also it’s a good idea to register the product for extra customer support if needed.

It worked fine for about 8 months and then suddenly my speeds dropped randomly and lost internet connection all the time. I contacted Xfinity dozens of time and even had a tech come out and we tested literally everything and it was this modem that was causing all of the problems. The app is a joke and constantly forgets all of your information. The company is an even bigger joke. good luck getting any help if you need it. the best you will get is a forum where they tell you to reset the router and unplug and plug it back in. DO NOT BUY THIS. They do literally anything to get out of honoring your warranty. A complete waste of money and it costs a lot!!!

Great product! Very fast speeds! Allows me to return my rented modem to Xfinity. Setup took a couple of calls to Xfinity customer service, but no more than any other time I changed modems.

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.

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

Difficulty initiating connectivity through my ISP. Seemed like their cross-connectivity was challenging. Otherwise, works quite well.

This is a great cable modem wifi router if you get internet through a cable company. The wifi works great for the whole house without having to get extra wifi hubs.

Installation with Comcast Tech was flawless. Speeds are awesome. Setting up wifi was a real hassle. Had tech support on the phone over an hour. Problem was resolved and everything is fully functional.

Solved our connection problem and covers the whole house.

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.

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

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.

Blazing fast, easy to setup and worth every penny.

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.

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.

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.

Easy setup and great performance. Highly recommended!!

Such a horrible wifi router. The modem itself works fine, I have no issue with my hard wire connections. The built in wifi on the other hand is so bad. At one point, my wifi connection was cutting in and out. This was persistent for a couple of months and stopped randomly. Regardless, the coverage still does not go far. I live in a 1000 square foot house and it cannot reach many areas. I only went with this router because a really good Netgear one I was using prior failed randomly. I decided to switch brands because I thought purchasing another Netgear router/modem I would run into the same issues. Instead I lost a ton of performance. SInce I no longer can return this router, I've opted to turn off the wifi and purchase a mesh network to use as a wifi alternative. I hate this modem/router so much I am still looking to sell it and replace it with a modem only option to run my new mesh wifi network that works so much better than this.

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.
