Customer Ratings & Reviews

Works well I have had no issues with it, set up was pretty easy. It does have a 2.5gb lan port but I have yet to be able to fully use it since my router only supports 1gb WAN but at 1gb/s it works well and have had no issues would recommend.

So far so good. It has a 2.5 G output, which I'm using, but with a 1 G connection. I plan to expand later with a 2.5G router. I've run dedicated lines to my back room, and plan to try a mini computer with a 2.5G Ethernet plug. I don't need to, so I've talked myself out of it so far. But I want to.

Bought the Arris S33 after my netgear CM1100 failed. Connected to Suddenlink without issues. I am getting faster speed than I was getting with the CM1100 by about 200Mbps which is great. Surprised by the small size of the S33. Real easy to install too. It’s connected to an Orbi RBK852. Wish the price had been a little lower but I guess you get what you pay for…

Works as expected. Very easy set up. You may have to contact your cable company to get it activated.

Bought this DOCSIS 3.1 modem from Best Buy last month and haven't looked back. Easy to setup and connect thru the Xfinity App on my smartphone. Getting over 600 Mbps reliably and my Linksys router doesn't keep dropping the 5Ghz signal

Xfinity setup was easy using their app. Connects and stays connected, plenty of bandwidth for the service I have. Nicer looking than my old one.

Works well paired with Amazon eeros 7. Upgraded from a 13 year old nighthawk module combo because we weren’t getting our full gig of internet

This unit increased the download speed instantly. The most positive thing about this modem is that you own it and don't have to pay a monthly fee on your ISP bill. The biggest drawback is that you have to call your ISP tech support to get it online. Sometimes you are connected to a Tech that knows his job and how to connect the new modem to their system. Other times you may get someone who just started and doesn't know a thing. Make sure that you see your Internet Service Providers company name on the box to make sure it is compatible.

Just set this ARRIS-Surfboard modem up a few weeks ago, so far so good. I had my IT person do the setup and he said the speeds were excellent and consistent. We stream our TV and have our phones and a ring doorbell signed into this and no lag or buffering to report.

Obtained this Arris SURFboard cable modem to replace a surfboard that got taken out by a close lighting strike. This is the latest-greatest version, installation was not an issue, and it seems to be working well. It tends to run a little warm so make sure it has good ventilation.

Purchased this modem as a recommended upgrade on the Xfinity service. This modem allowed me to utilize all of the 1gig speed plan that I'm on. Set-up was easy. Registered via the Xfinity portal

This is very a good modem. Key points: - very easy to setup - quickly connects to internet provider - pretty small compare to other modems - can use faster internet without modem upgrade since it supports 5000 megabits per second for download and 2000 megabits per second for upload

Simple. Fast. Space saving. Good looking. Exactly what i was looking for. Only complaint is the app support for it is non-existent.

I replaced my 9 year old modem with this one. Happy so far with this modem. I was worried about the bad reviews and heat issues but it has worked flawlessly so far. I was able to connect it to Comcast with their app. It did take about 10 - 20 minutes for the internet to come up but it has been very stable since. It also disconnected a few times at first but I am assuming that it was updating firmware. It does run hotter than most of my equipment, but not ridiculously hot. I have version 2 of this router. It is clearly marked on the box sticker with the model and serial number as V2. The only negative I have is that my ping times went up about 5ms from about 15ms to 20ms. Not noticeable during regular use.

I recently upgraded to the ARRIS SURFboard S33, and it’s been a game-changer for my home network. Right out of the box, the setup was quick and painless. Within minutes, I was up and running with my ISP (Xfinity), and the performance boost was immediately noticeable.

You know when your speeds got you down because yer Nanna be streaming Little House on the Prairie so hard you can hear Mick Landon through the thin walls while you're on your cam with your bae and he be stuttering? No more, this DOCSIS 3.1 beast will make the internet go brrrrrrrp brrrrrp!

Has worked great so far, set-up was easy and no issues at all in the week it's been up and running. Took Cox a bit to find the model but that's probably because it's so new. Using with the Netgear Nighthawk MK62 mesh wifi system. Like the new design as well. Small and modest but performs like a champ. Would recommend

Works great! Internet speeds improved after upgrading to this modem. The app did not work for installation - I needed to call Astound, and was on the phone for close to an hour.

Simple to setup and full of the features you're looking for. This modem is compact and a breeze to walk through activation with Xfinity. The 2.5Gb LAN port allows access to most ISPs over provisioning enabling faster than 1gig connections.

Excellent modem and easy to setup. Would have given it full stars, however it took well over half an hour to connect and multiple attempts. Did boost my speed significantly and corrected a lot of connectivity issues from my previous ARRIS modem.
