Customer Ratings & Reviews

Using for Xfinity Extreme service (requires DOCSIS 3.1). Pricey modem combo but this is a case of getting what you pay for. Service is very stable with no restarts required in the first three weeks of operation. Can't say the same for my old Pace router combo with Uverse. Administration is open and intuitive and is a great compliment to my Xfinity service. Current service is 300Mbits, but this combo keeps me future proof up to 1Gbit service.

Easy to setup cable modem. Works with Wide Open West (WOW) network. Fast download speeds 5G plus compatibility. Excellent reliability and doesn’t overheat with proper ventilation.

Easy install and set up! Has been very reliable and signal is very strong throughout the house. House is approx 2000 sq feet and have no "dead spots"

I needed a docsis 3.1 modem to fully take advantage of my provider’s speed. My old 3.0 modem wasn’t getting the job done. I am now getting the advertised speeds. Setup was easy. Wi-Fi range is pretty good, too.

The modem works great and was super easy to set up. I called my ISP company and they help me get it set up. This 2 in one (modem and router) is a no brainier, thereby saving rental monthly fees with the provider. The device will pay for itself in a year with a significant upgrade in performance. I've reserved the last star for future months of excellent service.

The device was easy to install. It does the job and improved my internet speed and WiFi. I think it’s a good product for a reasonable price.

Have been using this modem for a couple of years now and it has not failed even once. It delivers flawless data both inbound and outbound.The times that I have lost connection to data transmission, it has always been because of the signal transmission of the ISP.

If you are using Xfinity and are TIRED of not getting the speeds you pay for, you modem constantly crashing out due to an overload of bandwidth etc LOOK NO FURTHER. For the piece this modem is AWESOME on this that could make it better is if it was WiFi 6 for the price; not much of a problem though if your a smaller home (12 devices or less) save yourself the 15 bucks a month on the bill! This thing pays for itself after a year and you actually get to use the speeds you’re paying for this this modem!

Easy setup. Has been in use about a month and no problems. Can definitely tell a difference in speed, connectivity etc. Cheaper than renting from provider also.

has worked great even though xfinity ties to blame it for their lack of service

So far my speed increased from 70-80 mbps on my old router to 350 mbps now (primarily due to going from DOCSIS 3.0 to DOCSIS 3.1) ! So far am pretty happy with it.

Been struggling with the Cox rental modem constantly losing internet. Installed the Arris a week ago and internet has not gone down once. Highly recommended. I also use Eero due to a larger home and in combination with is 4 bars anywhere in the house. Save your $11 rental fee and in your own router. You will not regret it.

It is an excellent/reliable router with four ports required for set up to work from home. After 5 months of reliable use, internet issues surfaced. After extensive diagnosis with ARRIS which revealed no issues and several diagnosis & tech visits from COX, I repurchased the product but "COX" insists that this model is no longer compatible.. (ARRIS stands by their product and even replaced my other router in the event there was a glitch they may have overlooked)

Excellent modem router combo. Very reliable and easy to connect.

Giving 4 instead of 5 stars only because on initial setup, it took long than i cared for for it to kick in, and communicate. Works great now. Was half the price of new Netgear units and close to the same specifications. Purchased because old Netgear wasn’t taking full advantage of Cox internet speed I was supposed to be getting. I didn’t know this until I had called their tech support due to a lot of lag I was experiencing. (Not a Netgear issue. We simply because it was an older unit)

So happy that i found that router/ modem!! I love it!!

My old router/modem died so I got this one. This router is faster and more user friendly. It was easy to set up and works get. It was like night and day in difference. I would recommend this product

I picked this router for it's compatibility with my ISP and the excellent price point. I haven't been disappointed. Set up and operation was easy and straight forward.

I bought this item a little over a month ago. Setup wasn’t too bad and the tech people at Sparklight were very helpful. The speed has been slow to rocket but after having Sparklight over to check things out it was okay on our end, the biggest pi’s the three iPads, three iPhones, and internet TV. Also, we went up to their 300 plan and now it works great.

Awesome Router/Modem combo. I've got about 20 devices with Xfinity Gigabit internet. Wifi could be a tad better but range is excellent for my 1000sqft Average about 600mbps on the download while on wifi and about 950mbps when hardwired with Cat7 Ethernet. Returned the Nighthawk C7800 for this and am pleased with my choice.
