Greart modem for Xfinity
I recently purchased the ARRIS SB6190 modem to use with my 500 Mbps Xfinity WiFi(This modem is suitable for Xfinity networks up to 800 Mbps.), and I’m very impressed with its performance.

Performance: The modem delivers excellent speed, and I’ve tested both upload and download rates without any issues. Everything works seamlessly, making my internet experience smooth and reliable.

Installation Process: Here’s a step-by-step guide that I hope will help others:

Connect the Devices: Start by connecting the modem to your coaxial cable and power supply.
Download the Xfinity App: Install the Xfinity app on your smartphone and log in to your account.
Change to Own Modem: In the app, there’s an option to "Change to Own Modem." Select this option, and the setup process will take just a few minutes.
Connect Ethernet: Finally, connect an Ethernet cable from the modem to your router or directly to your computer.
Overall, the ARRIS SB6190 has proven to be a reliable choice for high-speed internet, and the installation process was straightforward.

Works well so far
I purchased a refurbished unit to save money and my two concerns were whether or not it had truly been refurbished and not just resold, and second was that I would have a hard time registering it with Comcast as it might still be listed under Comcast as in use by someone else.

It turns out that I did have difficulties getting it connected to Comcast but not for the anticipated reasons. To set up a new Cable modem the Comcast process was that I download an app to my phone and follow the procedure in the app, which was where I entered the MAC address of the new modem. But the app failed to function properly and I had to pay bloody hell trying to work through Comcast's support system.

I worked as a lab assistant at Scientific Atlanta back in 94 &95 when this stuff was being invented so I knew exactly what needed to happen to fix the problem but I had an extremely difficult time getting in touch with someone who could do what I asked. At one point Comcast wanted me to wait 3 days for someone to come out to may house and fix the problem. At which point I was nearly yelling at the Comcast people trying to get them to work outside their troubleshooting "menu"/"flow chart".

Once I finally did get connected to a person with the appropriate skills/knowledge the problem was resolved in a couple of minutes. The modem has performed perfectly ever since. I hope it continues to do so for years to come.

I can still get a little upset at the Comcast person who insisted that I should wait 3 days to have a service person come to my house so I could finally have a working internet!!! **UNBELIEVABLE**

Great router for 500 mbps
This modem is great! We have high speed Xfinity wifi with 500 mbps and paired it with a ASUS router and it works like a charm. Our internet speed is fast, accessible, and can handle several devices at a time. It was also super simple to set up on our own. With its small size, it is easy to store in a small location. The quality is AMAZING for the price.

No faster than the 16x4 version.
I bought this modem because my ISP claimed my existing modem was defective. But the problem turned out to be in their wiring. Never trust your ISP, especially if the support is outsourced to people you can barely understand. Suddenlink, (now calling itself Optimum) is by far the worst telecommunications provider I’ve ever worked with in over 30+ years. I've dealt with everything from giant conglomerates to tiny mom-and-pop telcos, and Optimum wins the award for absolute worst–by far.

This is a quality modem, but just because it’s 32x8 won’t make it run faster than a 16x4. Using more frequencies doesn’t give a better connection or improved reliability. So I went back to using my old reliable 16x4 version of this modem. I did add fans for either side to help it run cooler, though. (see photo) You shouldn't believe reports that claim modems last only a few years – that’s nonsense. Take good care of it, and it should last a long time. By that I mean, keep it cool! Most electronic equipment has insufficient cooling, imo. But add a little fan or two, and it will keep going and going. (I bought my fans on Amazon, of course!!)

I own many “refurbished“ modems, routers, and even computers. Over the years, I’ve saved a bundle doing that, and never regretted it. For most electronics, if it works well for 30 days, it will likely keep working for years. Buying directly from Amazon, I know I’ll get my money back if anything goes wrong during those first 30 days.

The 16x4 version of this modem is no longer available, so I highly recommend this 32x8 one. I’ve had no problem getting over 500Mbps with 16x4, so this one should work great, too. If you’re considering getting a DOCSYS 3.1 instead of 3.0, first make sure your ISP fully supports it. You could be paying extra money for nothing. My ISP claims 3.1 compatibility, but that’s just marketing hype. Years ago, they announced they would never support 3.1 features. If your ISP doesn’t *guarantee* to *fully* support all 3.1 features, you can confidently assume they don’t, and probably never will. Replacing their equipment to be fully compatible with DOCSYS 3.1 costs a lot of money, but marketing hype is free.
