Customer Ratings & Reviews

For the price, I'm blown away by the power. Comparable devices seem to cost quite a bit more and I had heard good things about it from employees so I decided to go with it, I sure don't regret it.

After referring to Comcast's web site, I chose this model to replace the company's which was 6+ years old. I experienced increased speeds right away!

Used it to replace Cable Company rental. It was approved replacement. Everything was fine and replacepent and all good. Would recommend !!!

I installed the modem and it was easy to hook up, cable installer registered mac address with Xfinity, and we were off to the internet Upload and download speeds were constant with Xfinity tests.

I am on Time Warners fastest internet service and speed test shows me being even faster. It also is very stable and I do not seem to lose the internet occasionally like I did with my TWC supplied modem

I noticed an immediate increase in speed with my Cox Communications internet service. Because of the number of chanels it has if my provider increases my level of service this modem is able to handle it.

Works great with no issues. If you have spectrum modem get rid of it and get this modem.

I bought this modem with a Linksys Velop mesh wireless router and OMG!! I gained 50mbps of speed with this modem. Plus I now save $11 a month for owning my own equipment with comcast.

Really simple and easy to setup via Spectrums web portal. Needed to have an additional flag set for the modem to come online.

My Internet runs so much faster with this router! It works much better than the linksys we were using. Overall, best investment we ever made.

Excellent Arris Surfboard Modem that keeps me connected constantly to my Comcast provider. Extremely easy to connect to my internet provider and my router.

My internet had slowed down to a crawl. I called the cable company and they suggested replacing the modem. They could not come do it for me for a week. I did it myself and it really helped.

Bought this after my old modem went out and so far has been an excellent replacement. I now get my Max internet speeds of 180mbs download and 15mbs upload with no problems. I highly recommend.

I had the sb6183 first and loved it but I upgraded my whole network and the sb6190 works even better. Never have to reset it always have a consistent strong signal and download and upload speed

Easy to setup, fast connection and seamless operation! Definitely would recommend this modem for Xfinity users, totally compatible with no issues whatsoever.

With the exception of comcast online "support", this was an easy upgrade, just plug and play as long as comcast people in India can understand and write down the right MAC id#.

I have noticed the wifi being a little slow. I decided to upgrade and what an improvement. I needed the 32 channels since I have over 18 device attached to the internet Very good improvement

Works great with Comcast/Xfinity Extreme 250. Had an 6141 before upgrading to this modem and everything feels faster than before. Latency and speeds definitely have been upgraded. Highly recommended.

I was having download speed issues while streaming...always seemed to be buffering. With the 32 downstream channels, I have no issues with buffering any more.

I upgraded my router to this product several months ago. It has worked flawlessly and it it dependable. Bought another of the same for an emergency backup.
