Customer Ratings & Reviews

Fast. Works well with Xfinity and is supported. This was an upgrade over an older cable modem to get faster speeds.

Works amazing no issue at all, followed the app which made the set up so easy

We finally departed from the C-cast/xFin__ gateway and we're not looking back! No more rental fees and the performance of this modem is second to none. We matched it up with three TP Link Deco 6e routers and the coverage in our large home is flawless.

Modem is fast as advertised. Connected it to Xfinity and it came up without problems.

Using this modem with Xfinity 1 gig service. Installed with the Xfinity online process and it worked flawlessly. Getting 944 Mbps down and 44 Mbps up. My WiFi is the eero Pro 6 with 3 pucks. One puck is directly connected to the modem and the other 2 are just over WiFi. I’m very happy with the whole system. Had the Modem for about 3 weeks so far and have not experienced any issues whatsoever. I would highly recommend this modem.

I love this modem, it was so easy to set up. It's can handle the latest speeds from my ISP which is great. So glade I purchased it. Awesome.

The ARRIS - SURFboard S33v32x8 Multi-Gig Modem was suggested by our Comcast Technician as the cable company will be providing higher speeds as the previous Arris Modem was no longer adequate to handle the increase internet cable speed.

I needed a little workhorse for the type of internet I require. Teleworking & School at home drive up the need for internet that is not spotty. I tried cheaper models, only to be frustrated by constant drops and dips in internet speed. I went ahead paid a little more for this type of modem. I do not regret it. Internet speeds have been consistent. I never worry about bandwidth issues because this modem does what I need it to do!

Good modem that hasn't dropped my connection since. Coming from a Motorola SB8600, which had so many issues with dropping my wifi connection daily. The SnR signal was good, but I ended up having to reboot it like 3 or 4 times a day. Imagine while working from home and doing something important with a client and all of sudden you lose connection? That is completely unnaceptable. If it helps, I have a technical background and no amount of troubleshooting firmware will help my particular unit. I verified with Comcast that it was not my wires or the ethernetdrop causing it, or the coax. In short: Your mile varies significantly a large amount of these 3.1 modems can have handfuls of issue.

The modem is great and saves on the fees! Also very future proof for high speeds since it can do gigabit speeds.

Had a problem with download from the internet, I was only getting 10mbps to 16 mbps when I paid for 1 gigs last from cox. Problem was outdated modem and router. Upgraded to Arris G36 and my download speed is now 850mbps. Very happy.

Very easy setup and haven't had any problems so far and everything is working great.

This is a great device to run off your fiber optic network. Recently we got fiber in my area and boy does this purchase was needed. I set this up and routed 3 Ethernet lines from it through a divider and also connected a wifi modem along with it. It works magic. I run both my chromecast tv dongles and never wait or miss shows. If you ever sign up for cable, please buy your device, it will mean the world in service. I was given this piece of advice and never looked back.

Quit renting the cable modem and buy one. This is very fast and reliable.

No fus no muss good price setup easy working like a champ

Fantastic performance, super easy to set-up with Xfinity, just connect and contacts Xfinity to provision, then it runs super smooth.

Working great. Easy setup. Works better than Netgear CM1200.

Gets the job done use it along with another router

This modem performs great! No issues so far. I recommend it.

this is so much better than the one comcast provides
