Great modem for the price. Always go to Best Buy! Easy to use and to set up. Would recommend to everyone. Small and compact as well. Buy one now for 1 GIG speed.

My father never updated his router when we first installed Roadrunner about 10+ years ago. He wasn't getting the speeds he was paying for and I told him his modem was bottle necking his speed. This was more than enough for the 60 MB/s he was paying for but I wanted to have absolutely nothing interfering with his internet. Setup requires you to call your internet provider, but setup was about 5 minutes. I love the new speed and ease of setup.

-Admin/Password settings works -Fastest speeds 98% people need -Cheapest option -$20 for 4 year Best Buy coverage for when it shats out lol

Easy install, great product and compatible with Xfinity.

i purchased this modem so i could receive the 300mbps speed from TWC after installing this my wired speed to my desktop is 349mbps wireless is 186mbps so it was a great purchase and well worth the price. the TWC provided modem will not produce speeds like this. very easy setup . just plug it in wait for all the lights to go solid and call TWC to have them activate it. done!!! * however* you will need a pretty good router to see speeds this high with this modem

When I was looking for a cable modem to use instead of leasing my Spectrum modem, this modem was the best value while meeting my minimum requirements of 300Mbps and 16x4 channel bonding. It was a great deal, and after I found it on sale and used Reward points, it was almost the price of its lesser competitors. It has far exceeded with its speed, twice as many channels and is 1/4 the size of Spectrum's modem so it's easier to hide. VERY HAPPY

Unit is solid and does its job well, three weeks as of this writing. It is not complicated to operate out of the box, and does not need any attention after connection has been established. The unit gets quite warm. Here are two important "lessons learned" connecting this unit to Comcast Xfinity: (1) You have to call Comcast to authorize the device; it is not automatic upon plug in only. (2) If you run into a problem that wired internet works, but wifi internet does not seem to work but rather, shunts you to a Xfinity login page: You have to change the DNS server address on your wifi router (downstream of your SURFboard). Change it away from the default to a non-Xfinity, non-Comcast server. My successful choice was Google, 8.8.8.8 is that IP address. To find this out took my untold hours; not Arris' fault, but I am aghast how not available this info was on the wider internet.

Hello readers I purchased this Arris modem so I could stop the monthly Fee from my Comcast provider. I'm a Big Fan of Comcast however I wanted to lower the cost of doing business with them and paying the upfront cost of the Arris 3.0 modem would do this in time and yes it is superior to the combination Modem/ Router I had from Comcast at a $10.00 monthly Fee. My Tech savaay Son liked it a lot and said Dad that's So awesome I think I'll move back Home, I said no no I'll buy you one for Christmas. (LOL) I really like the new Arris modem and in time it will pay for itself and start putting money in my pocket. I waited for two months to write this review to see if it gave me any issues but it is working excellent. Thank you for Reading Reviews help consumers

So easy to set up. We set up with xfinity, did everything through the app and did not have to call anyone to get our wifi set up in our new home. App takes you through all the steps and it was so easy, even for someone who has never done anything like this before.

Worked right out of the box. Nothing complicated and does exactly what I need it to do

I read a bunch of reviews on a lot of different modems. While this wasn't showing up specifically in Best Buy search as Comcast compatible, further web research and then speaking with a rep at Best Buy confirmed it would work. Works great! Easy setup! The time consuming part of setup was dealing with Comcast to have them provision the new modem, but worth it to save the $10 per month rental fee. This will pay for itself in less than a year!

I've had this Cable Modem for several months now and have had no problems whatsoever with it. Installation was easy and only required a phone call to my cable company to activate its use (as well as returning my old Mediacom Modem). Now I no longer pay a $5 rental fee to my cable company, which over time will pay for the Modem. My only gripe is not with the Modem, but with my cable monopoly that I'm stuck with if I want fast internet speeds!

We desperately needed to replace our old modem and didn't even realize how badly it needed replacing until I bought this one. Have had it since August, 2021 and it does a fabulous job with connectivity. I've never had to reset it even once after connecting it to our coaxial cable. Speeds are phenomenal too! Love it!

We had been having issues with our internet so one of phone no-support techs said the problem was our modem. So I go bought this modem as a replacement - it had twice as many download channels as the one that I had and I think that i can notice a difference. Setup was easy - plug and play right out of th box. The internet issues were no due to the previous modem as we are still working through them with the provider.

Worked great, never had 1 issue with this over the years

It worked as described and has been very beneficial

Very easy to setup and use. Its cheap compared to renting one monthly from Xfinity. Saves you lots in the long run plus the Xfinity ones go bad after a few years while this should last 10 years.

Easy installation. Worked as described. Brought me into this century. Fast.

I purchased and installed two of these units, one in a rental house we own and the other in my own house. It installed perfectly with Comcast without having to contact customer service. Just make sure you know your account number and phone number associated with your account. We have had no performance issues. The lights are bright, however. It is not a problem in the office but could be annoying if installed in a different room.

Dependable modem - last one worked for more then 5 years. This exact same product has been on the market since October 2015 and is still for sale! Tried and true. As with anything connected to a cable that runs from outside your home, any electrical surge can take this out. That's what happened to mine, here in Florida, the lightning capitol of the US. Bought the exact same model, called my Internet provided and was back in business in about 15 minutes...speedy and maintenance free. (Your ISP provides the firmware updates directly.) 1Gbps internal LAN to your home router, and on my Xfinity, it is capable of up to 800 Mbps (depending on your plan, and the ISP speed "tier" options). No need to buy the "latest and greatest, more expensive" when the Wi-Fi maximum speed is 9.6 Gbps maximum throughput across multiple channels, and Wi-Fi 5 offers a maximum of 3.5 Gbps. Your home network is only as fast as the slowest common denominator.
