Customer Ratings & Reviews

Have owned this device for nearly 3 weeks now, and it's performed flawlessly. In conjunction with Comcast service for 100 Mbps broadband internet & TV, it fulfills all the claims on speed & reliability. Very happy with this purchase.

My old router was not compatible with Xfinity any more and I have to change it for another one. Sb6190 is the best bet which is faster and reliable at one hand and also not expensive compare to other routers available.

Purchasing a good modem is a great investment. You will save money by avoiding the extra monthly fee from your internet service provider and increase the performance of your connectivity. This modem is great and reasonably priced.

Easy setup. Fast connectivity. Great upgrade from last modem

Fast cable modem at a good price mark. It was also very easy to set up. Tech support was readily available and knew exactly what they were doing. We get our full internet speed with this modem. Definitely worth it.

Easy to install and is working well! We also added Eero 6 dual-bank mesh system, so together we've improved our internet speed and accessibility throughout our whole property.

I needed to update my modem to 802ac standard and be compatible with my Spectrum Cable TV system. This unit was easy to install, with only a phone call to my Cable TV provider to provide them the unit serial number.

If your ISP, Cable company supports this is the best modem you can buy. 300MBps with Cox and will have no problem when 600MBps will be available. The performance depends a lot on your ISP but at least the modem is not the limiting factor.

Wish I had done this long ago. Had an Xfinity rental and it was time to stop wasting money. This modem was easy to set up and I paired it with an EEOS. They work well and were easy to set up.

Have had this modem for a month now and the quality, speed and performance is outstanding. I would recommend this to price minded users who want great internet service without renting a modem.

Purchased this because I didn't want to rent from the cable company. This works great, I have had no issues, its fast, what more could I ask for?

I love this modem and has worked fast and flawlessly for a few months now. Lately, I have been having to reboot this modem (4 times in 3 weeks). Not sure what caused it as of yet. I'm thinking it disconnected due to heat, this thing gets a bit hot. Will try and figure out if this is the problem or if the problem is with my ISP/Cable company.

My Comcast ask for replace my old modem to this new version . Like always Motorola work like at charm and setup was no time. Problem was make Comcast tech make work on there network..Patient is need with Support...

Speed is ultra fast and easy to install i love this product

I purchased this along with a Nest mesh router and I am very happy with it; no lag time and downloading is a lot faster than before so I would definitely recommend this!

I am pretty technical but not at the level to get all detailed on speeds and feeds here, but I can say that you do need to upgrade your modem to make use of the increasing ISP speeds and the many devices in your home. I was using an old modem and didn't realize I capped the maximum download speeds on it compared to what I was paying for to my ISP. I upgraded and did a speed test and actually got my advertised download speeds - which is relative to your saturation on shared broadband connection if you use a cable internet service provider, however. So just by upgrading your modem doesn't mean you are going to get faster speeds. It's all relative. But if you are using a an old modem that can only download at 150Mb/s and your provider can do 200Mb/s, then you're leaving some bandwidth on the table.

Easy installation and setup with its app. Internet runs smoothly.

This is a great modem. There was really no setup at all. The price was great. We only have 400Mbps right now but great that we can upgrade to gigabit service with this modem if we need!

Nice inexpensive replacement modem for DOCSIS 3.0 service -- been using the Motorola/Arris modems since early 2000s -- have gone through probably 7 or 8 throughout the years -- this model has more channels than my previous -- got this modem to rule out issues with my previous modem (which was only 2.5 years old, and is fine) -- but had to do that before my ISP came out to troubleshoot my packet loss issue -- attributed to neighborhood saturation during the pandemic, as my signal levels are great -- but I am keeping this modem, anyway, since it does have twice the ds/us channels, and is capable of pushing higher throughput, if I eventually upgrade service

Works great and super easy to set up with detailed instructions!
