Customer Ratings & Reviews

This device does exactly what it needs to do and provides high speeds for Comcast users. 2nd one I've gotten when needed to upgrade for higher speeds and great brand.

I have xfinity internet. I used to use this same brand modem just an older version with 8 x 4 channels. The internet was ok but not the best. After getting this modem my internet is more consistent and I can use more devises at the same time without bogging down the WiFi. It’s definitely worth it if you have a lot of devices

The Surface dock is a really great dock for a surface computer.

Supported the speeds I needed with Comcast. I easily attached it to the wall to keep my wiring tidy. Not sure when I will ever need the second network port on it. I can see that being useful for troubleshooting a dead router connection, or if I ever need more than 1Gbps from Comcast.

Arris modem was easy to activate and use with our WOW Internet Service. We have had absolutely no issues with dropped internet due to modem issues.

I am with Cox communication and they are able to support this modem. If you are with them they will give you a docsis 3.1 modem that has the phone jack. If you do not need the free one from Cox and you are looking for the two port RJ45 then this is the way to go. This will also support the 12 gigabit connection and faster speeds once cox can support it.

If you want the fastest internet available in the state you already have a GOOD router (and current technology), then this is what you need to complete your internet package. It does exactly what it needs to do- perform FAST! I recently upgraded from the 2nd fastest internet speed and required this device. It is a game changer.

Awesome modem, basically installed itself, highly recommend.

This modem is AMAZING! I switched from a Netgear unit, i will never go back. Given i have Cox, this waz suggested by Best Buy (great choice!). If you are gigablast ready and upgrading, this modem is a solid choice. 5 minutes on the phone with Cox registering, very simple, and WOW!!

Got this to replace an old Lynksys Nighthawk. I am very pleased with this modem. It was ridiculously easy to set up.

Easy to setup with Xfinity. Web based setup by yourself, or guided. Let it reboot twice before finishing though. Steady connection, great price at Best Buy. Honors price matching at the register. On 1GB connection , it averages about 850-950.

I’ve been living with the product for about a month now and so far have zero issues. I wanted something that would be somewhat future proof (DOCSIS 3.1 and speeds over 1 Gbps). Be sure to call your provider before setup and provide them with the MAC address, after that its plug and play.

this new modem helped boost my current internet speed, and shortly when I upgrade to Gig speed it will work perfect for that too.

Excellent, easy to set up, small and compact,........

Surprisingly smaller than it looks, not as simple to configure with when connecting to Comcast. Once I have it configured, had issues with heat. I connected two USB powered fans next to it and no longer gets hot. Should work a lot better now and less chance of failure.

I purchased this to replace an older model. Much faster speeds and easy setup with Xfinity.

love it! exactly what i needed for my new house. works perfect.

Arris modems are solid. We have used them for well over 10 years, and the only reason I needed to buy a new one was due to lightning damage. Having a good quality product as easy to pick up as going into Best Buy is really great. Once it is in it just runs without a problem.

Great product, reliable and FAST. Set up was quick and easy!

I am very happy I got this unit. quality better than the rental one. Also I saved 20 $ per month for the rental one.
