Customer Ratings & Reviews

I was skeptical at first and a bit afraid to own my own modem. But after activating with spectrum customer service I haven’t had any trouble and the connection speed is what I pay for. 1 gig = 1 gig

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.

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.

Great modem, increased my download and upload speed! Needed this modem to upgrade to higher speed internet and it’s worked out well! I need to upload high resolution files for work and so far it’s been super fast and just what was needed.

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.

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

Great modem lasted 3yrs for me and I had the warranty with Best Buy so I upgraded but easy to set up and never had a problem. Just remember to call your provider for the modem info

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

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!!

Good customer service to check my warranty. This modem works well for a few years. So i keep buying the same brand every time.

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.

I upgraded from SB6121 and immediately my 75Mbps plan was boosted to around 85-88Mbps. With the recent increase from 75Mbps to 100Mbps, I am connecting at around 118-125Mbps. I had to call Comcast to switch my modem but it was quick and easy.

Excellent, reliable fast modem. Works with all cable providers

I am very happy with AARIS modems. My past two modems were reliable. We are a very connected house. I refuse to purchase a modem and router from Xfinity. I bought this. It’s coupled with a Linksys Velop Mesh Router. We are a family of 5, and pull down over a TB a month. I am pulling down speeds of 450 Mbps. You won’t be disappointed.

Pros: Runs perfect. Superfast ! Lights are bright. Great price.

Great speeds and working good so far, connectivity is great.

We've had this modem for about a month and have been very pleased so far. Installation was straightforward and the performance has been great. We have Xfinity internet service and are using this, a Ubiquiti EdgeRouter X, and a wireless access point to create an always-on wired home network with optional WiFi.

So far so good, high speeds, reliability, I am happy with product..

I had the Xfinity modem, for years but it always had to be reset on a daily basis I called them to replace it and they kept telling me it's the newest one. Lies there equipment is just junk. So I bought my own modem best decision I could make I haven't had a single problem since I went live with it.

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.
