  • Blazing Speeds Meet Xfinity Activation Challenge! 💻🔧🌐
TLDR: ARRIS S33 modem: significant speed upgrade, perfect for 1.2Gbps service, but challenging Xfinity installation. 💻🚀🔄 Upgrading to the ARRIS S33 modem was like jumping to lightspeed in my home network. Coming from a history of using ARRIS products, which have always been stellar, this move was more about staying ahead in the internet speed game. The motivation? To tap into the full potential of my 1.2Gbps service. The previous modem was a faithful servant in the realm of DOCSIS 3.0, but the S33, with its DOCSIS 3.1 technology, has taken things to the next level. It's like unleashing the full power of my internet service. On my M1 iMac, I'm now hitting an average of 950 Mbps, which is phenomenal. It's a five-star experience in terms of performance. However, it's not all smooth sailing. If you're with Xfinity, brace yourself for a bit of an odyssey. The modem itself is designed for simplicity – a plug-n-play dream. But the activation with Xfinity? That's where the plot thickens. My attempt to activate through the Xfinity app hit a wall. The app was a no-go, and the chat with Xfinity agents turned into a marathon of confusion and miscommunication. From compatibility doubts to system non-recognition, it was a series of hurdles. The escalation didn't smooth things out either. A trip to the Xfinity service center, based on agent advice, turned into a waiting game and a revelation that the service centers are just as much in the dark. Despite the assurances and escalations, the solution still felt elusive. But, in a twist worthy of a tech thriller, a call from Xfinity's tech group brought the light at the end of the tunnel. The modem was finally configured, activated, and ready to go. The ordeal? Roughly 4 hours, multiple chats, a service center visit, and a pinch of patience. In conclusion, the ARRIS S33 modem is a beast in terms of speed and reliability, a definite upgrade for anyone looking to maximize their internet service. Just be prepared for a bit of an installation saga with Xfinity – it's worth it in the end! ... show more

  • A very fast, and so far reliable modem
I should start out by stating that I am an IT professional, and have been in the industry for 24 years. I have a family of 6, all of whom are doing school remotely in this COVID world, and I've worked from home for the better part of the last 8 years, so home Internet is my livelihood. I also have one gamer in the family who tests bandwidth and connectivity to its limits for me. We moved (in town) November of 2020, so I have been on a Netgear C7100V for the past 5 months. Which, granted was its own Wifi router (2-in-1) and had a smaller price point, AND was an older model than the Arris S33. For the last 45 or so days, while on the old Netgear, my Xfinity connection had been dropping periodically. Turns out the Netgear C7100V was recently removed from the compatibility list. I figured I better buy a new modem that was on the list before I call Comcast and complain because the first thing they're going to say to me is go buy another modem before they'll support my problem. Buddy of mine in IT had the Arris S33 Surfboard, and raved about it, so I thought I'd give it a try. And because my old Netgear was a modem/router combo, I had to purchase routers too, so for context, I should disclose that I also upgraded to an Eero 6 pro 3-pack tri-band mesh wifi6 router system too. BUT, I can say unequivocally, that I never got anywhere close to the 1Gbps speeds I was paying for with the Netgear C7100V. 600mbps, tops, which is a bandwidth limitation of that device that I lived with and dealt with because no one ever got 600mbps TO the modem over wifi anyway, so the bottleneck was before the Internet egress before anyway, and still is, and probably always will be with wifi, but I digress. But with this Arris S33 Surfboard modem, I get a consistent, all day, everyday, 900+mbps of my 1gbps service. And, so far, no drops in service either since installing the Arris (fingers crossed it's only been 3 days). But even if I do, this review is still relevant because if I continue to experience drops even after the new modem and router, pretty sure it's the service provider at that point anyway. It's smaller, easy to use, quick simple setup, and if you have the Xfinity app on your phone there's no need to even call Comcast. You don't need to be an IT pro either. It took, like 20 minutes to setup, using the included quick setup guide, and it's been "set it and forget it" ever since (again, so far). I'll come back and revise this review if that changes, but I have no complaints. ... show more
