Customer Ratings & Reviews

Bought this to replace the crappy modem that was provided by the service provider. Works far better and haven't had to reboot once.

upgraded from SB 6121 to sb6190 .Modem takes sometime to connect to comcast network when restarted every time, speed is good. but seems pricey. anyway Comcast will upgrade their network equipment everytime and we too have to update with them

I bought this modem and it has been very reliable for just over a year. Don't buy the extended warranty Best Buy wants you to buy.

The modem works great with my home system. It was an easy installation and worked perfectly.

Great modem. Coupled with netgear orbi my internet in the house has improved two fold. No more paying rent to the internet company for their box.

Works great! I've never purchased a modem and I went with this more expensive one to play it safe and it's worked great for me.

I upgraded my internet speed to 400 MPs. My old modem couldn’t handle this. Bought this one and now it up to 420 average.

Modem has worked great since I bought it. Hardest part was getting my service provider to disconnect the current modem and install this one.

Excellent product!!! It works perfectly with RCN and save money from renting the device.

We had issues with losing internet services. Since we purchased the new modem, the issue has been resolved.

Purchased to replace my rented xfinity modem/router. If you haven’t done the same I highly recommend so. Faster speeds for sure and it pats for itself in a couple months

Went from just a router to router and a modem Excellent move Internet works extremely well now very happy with it

I struggled with Spectrum internet and the inconsistency the internet was provided, having a stable multi channel Modem fixed my issues

I purchased to replace the modem I was renting from the cable company. Saving $10/month, pays for itself pretty quickly. Setup was very easy.

I highly recommend this modem for anyone seeking to get the most from their high speed internet provider. In my case I'm with Spectrum (formerly TWC).

I needed a new modem and this is the one I got. Good speeds for my internet capability. Decent warranty for a device that operates 24 hours a day.

This unit is way better than I expected. Works perfectly with my Nighthawk router. Very easy to install.

Did its job and I have no cons with it, to be honest. The price is a little high but it's good.

Quick and easy set up right out of the box. I was back up and running in a matter of minutes! Very happy!

I upgraded my internet with Cox and needed a faster modem. Was quite fast, but after that initial speed test, the past few weeks have slowed down. not sure if thats Cox or the modem. But still faster than my previous service.
