Definitely does what it should. My old arrris surf board was lacking. I had to reset modem every day to get 800mbps speed. Bought this one and is solid speeds remain up in the 700-800 mbps range with no resets. Hopefully this on last longer then 2 yrs. Reccomend getting geek squad protection just to switch out every 2 years so need to worry

great connectivity and easy connection. good quality build

Modem is very fast! However spectrum doesn’t really support it and the self install built in won’t even work. After provisioning it would lose connection every few hours or days depending. Took it back tried another, same thing. I believe it is spectrum with the issues though. Also it doesn’t play well with my arris mesh routers.

Easy to set up with xFinity and has worked without any problems so far with my gig set up!

Great modem to upgrade speed. Easy to setup with Breezeline service.

Works so much better than my old one. Actually stays connected.

This was a piece of garbage. I had it installed by the internet provider (Xfinity). Within 2 hours it stopped working. The unit got so hot that it burned my hand if i touched it. I would unplug it, let it cool down, plug it back in and it would work for about 45 minutes and then overheat. My research on the Arris customer forums show this is a common problem. I boxed it back up, and returned it to my local Best Buy, and replaced it with a Netgear modern that has run well for the past month. I had always bought Arris (Motorola) modems in the past - never again.

Replaced a DOCSIS 3.0 cable modem and my service is now super fast - upwards of 560 Mbps down and 55 Mbps up...

Rock solid performance. This is a must have for cable internet users.

I am giving the SURFboard S33 only 3 stars. The unit worked well and delivered what I would expect, but after 15 months it died. It has a 2 year warranty and I am currently working on getting it replaced or a refund. However, there only seems to be a support community to contact Arris. Their support page says they have live chat and phone support, but when you go there there is only a link to the community and no phone number.

Easy to set up. Works great with the Eero nest Wi-Fi. This modem is fast and reliable.

Modem works flawlessly with Comcast. Currently on their 1.2Gbps/35mbps plan and have no problem hitting those speeds; it goes over due to Comcast over-provisioning. Easy to activate as well. Should last a very long time.

I have Spectrum. I tried getting set up with their free crappy modem. Kept dropping me. Finally I decided to spend the money and get my own. Works perfectly from the moment I set it up. All I had to do was call Spectrum to activate it on their network. Took all of 5 minutes. I would highly recommend you go this route.

Easy to install. Seems to be faster. Recommend by service provider.

Works great. Happy i got it. Looks good with the rest of my belongings.

Has been working great overall with a few rare intermintent issues but overall working great. Very easy to set up

Latest and greatest in gigablast technology. This device works great to stream all my stuff great with the new gigablast service for my cable company. Has options for future expansion. Always loved Arris products.

Upgraded from the MB8600 to this S33. I used the 2.5G port from the modem to my PFsense and I get 1,200 Mbps download on xfinity service. Before I was limited to 945 Mbps.

This baby keeps my connection stable and speeds are great. It's not bulky also.

This is a small but powerful device that deliver 1,000 Mbps with Xfinity ISP. So far, very stable; The specifications state that it can handle up to 2.5 Gbps bandwidth ISP and with 2 WAN ports is a plus. I am happy with this unit
