Customer Ratings & Reviews

Great modem easy set up with spectrum. Hate the app. Totally unnecessary but they try to shoehorn you into downloading and registering it

Very fast upload and Download speeds. No drops and it is secure

Super fast with no problems. Dual LAN connections make managed networking easier. Highly recommended. Has 10G and 1G connections. It does get warm so cool area recommended for installation. It will last longer if it keeps cooler.

So far so good. It has a 2.5 G output, which I'm using, but with a 1 G connection. I plan to expand later with a 2.5G router. I've run dedicated lines to my back room, and plan to try a mini computer with a 2.5G Ethernet plug. I don't need to, so I've talked myself out of it so far. But I want to.

Had a unit from another brand breakdown and needed a new modem, wanted to try this brand out. It has been lightning fast and consistent in its performance, with easy setup and a lovely small footprint that makes it so easy to place. 5*

Upgraded from my modem router combo that ive had for 6 years now. Easy to hook up. Its much smaller so it takes up less space. Looks nice and sleek with the blue light in front. 2.5g ethernet port. Was able to activate it easily through the xfinity app. My internrt amd wifi connections have improve quite a bit after this upgrade and biying a new router as well.

I had been wanting to get rid of my poorly performing "upgraded" modem supplied by Spectrum "for free", The old modem needed to be restarted approximately 4 times a week, the Arris modem is working incredibly well, was easy to set up, and my upload and download speeds are dramatically improved. When paired with an Orbi router and mesh network, my entire home and yard get smoking fast internet speeds. My three millennial children are impressed; that is the best endorsement I can think of.

Works as expected. Very easy set up. You may have to contact your cable company to get it activated.

Always recommend to have your own router rather than through your isp. Last surfboard modem finally went out of after almost 10 years and never with any issues before it finally bit the dust. So far this one seems to be working just as well. Probably overkill for most people’s isp provided speeds but if you’re over 300mb/s it’s worth it for future proofing especially with having a 2.5gbs port.

Excellent. I had zero issues setting this up with Comcast. Took 5 mins to register it on their network with the app. Now I get much faster and dependable speed out of my 1 gig service. It has a very small footprint, really very small. This plus TP link Deco mesh WiFi devices really helped all my streaming devices, game console, and other various WiFi things work flawlessly with no lagging.

The modem works exactly as expected. Setup was straightforward, and it provides a stable connection without any issues. It's been consistently reliable, meeting all advertised performance specs. No surprises—just solid, dependable performance.

I had another modem and my wife & kids regularly complained about the slow internet speed. My kids have a PS5 and my wife streams Netflix and Amazon Prime. I also work from home a lot and have to admit that the internet was slow, especially on Zoom meetings. I increased the internet speed through our carrier but that didn't help. I did some research and found this modem. There were more expensive options, but after going to Best Buy and talking to an associate I really couldn't justify paying significantly more for another modem when this one cost considerably less. It was easy to connect, and after using it for several weeks I would definitely say I'm happy I made the choice to buy this modem. I haven't had any complaints from the wife & kids and connection for work has been much better also. Overall, for the money I think this is hands down a great choice.

Fast and reliable. I've had this running for a couple of months now and it's been rock steady. I get great speeds and setup was easy once I got my ISP to actually pick up the phone.

Xfinity setup was easy using their app. Connects and stays connected, plenty of bandwidth for the service I have. Nicer looking than my old one.

Bought this DOCSIS 3.1 modem from Best Buy last month and haven't looked back. Easy to setup and connect thru the Xfinity App on my smartphone. Getting over 600 Mbps reliably and my Linksys router doesn't keep dropping the 5Ghz signal

I've always been a fan of Arris products, in this modem does not disappoint. Simply put, it is the best-value multigig modem on the market right now. The 2.5 Gbps Ethernet port is a fantastic feature, especially if you have a router that's able to take advantage of multi-gig WAN. It'll also help you take advantage of any overprovisioning that your DOCSIS provider is offering, and does it at a fantastic price...hundred(s) less than Netgear. (In our case, we pay for 940 Mbps, but with this modem, saw the appreciable increase to 1.345 Gbps.) I guess I'll mention as a final point that Arris has fantastic support, should you encounter any issues or have any questions. I've owned previous products from them in the past, and even if I had an issue with them, the customer service alone was enough reason to continue doing business with Arris. When it comes to this modem though, they have created a rock-solid, state of the art, class-leading device – and I have no complaints whatsoever! Great work, Arris. :-)

Our cable provider secretly upgraded our internet to 1Gb but did not tell us until I noticed it in our monthly bill. However, our old Surfboard cable modem did not support 1Gb so their free upgrade required me to upgrade it with this unit. This unit does not come with Wi-Fi which was fine as I have a Wi-Fi access point and did not need it. This cable modem has been functioning flawlessly since we got it. Setup was plug and play. Just one call to the cable company to get it registered with them. Took all of 20 minutes from box to running. Should be good now until I get past 2.5Gb internet speed which should be a ways off.

Save your money! Buy this modem! Stop giving your ISP unnecessary money to just rent their own modem. Own your own. If you’re already paying for a 1Gig Internet connection, this modem will not cause you to have any drop out. My download and upload speeds are way better than before. This modem is a bit pricey but it’s definitely worth it. Connections have been no issue. Installation was quick!

I bought this when my Xfinity internet got upgraded to the gigabit plan. I did have some a couple of cheaper DOCSIS 3.1 options available and went with this one mostly for aesthetic reasons as I keep my modem and router out in the open. Technically I am on the 1200Mbps plan, though my router only has a gigabit Ethernet port and cannot take the full bandwidth from the 2.5 gigabit port that is on the modem. Still though I am consistently pulling down 950+ Mbps on my speed tests and everything has been super stable since I first installed this a few months ago. My previous modem was also a Surfboard and I've had good luck with their modems.

Purchased this modem as a recommended upgrade on the Xfinity service. This modem allowed me to utilize all of the 1gig speed plan that I'm on. Set-up was easy. Registered via the Xfinity portal
