Customer Ratings & Reviews

I had been paying for Xfinity equipment rental fees for years, but I finally wised up and bought this Arris unit. No issues whatsoever thus far - just needed to call Comcast to activate it, and it’s working great. I’m using the Google WiFi mesh network with 3 access points and I’ve been very pleased with my internet’s performance.

Works great with comcast. Is super fast and very reliable.

Easy installation. Working great. Reasonable price.

Very reliable never have any issues and easy to install.

I purchased this product to replace a similar product that had reached the end of its service life. With my current internet provider, I am achieving download speeds in excess of 400 under optimal conditions and close to 200 in suboptimal conditions. It works great with my wireless router. I would definitely buy this product again.

i own a nighthawk XR500 that pair perfectly with this modem i haven't get any Lag problem so far since bought it the only problem is the x1 compatibility for those who like x1 in my case i use my gaming router phone app to configure and check everything

works great and was easy to set up. Have not had any issues.

I bought 2. Super easy to use and faster downloads

Super fast and no problems yet. very easy to set up

Comcast finally forced me to buy a new modem. But no way was I going to give them the satisfaction of ripping me off by "renting" their equipment! Why rent when you can buy your own and save MUCH money over several years? This is an excellent brand that performs very well.

I picked this to replace the SB6120. The SB6190 is a beast as it is very stable. In fact the only time I've had to restart it is when we get the occasional power surge. It's super fast as i'm tiered to get 150 Mbps and I'm consistently getting 175-178 Mbps. I have this paired with an ASUS RT-AC88U and I get great wireless speeds throughout my house as well.

Works great- easy to install. No complaints yet. Happy

So far this has been excellent, easy to set up and seems fast.

Awesome modem, very fast for the price, great choice!!!

Upgraded the home internet and need a new modem. Having the old surfboard that was very reliable and easy to use, this was an obvious choice and recommended for the ISP. Set up was a breeze, the ISP took a bit to find the MAC on the device, bit once it synced, haven't had an issue since.

Made my internet speed much quicker and price was good.

Best Buy Rep recommended. I asked for a modem that was not expensive that would meet the new standards of Cox Cable. I am not an internet junkie and did not really know what I needed. I did know that I did not want to spend several hundred dollars. Got this modem, took it home, plugged it in, WORKS GREAT. Easy to set up and install.

This is the only modem WOW supports for 500M - 1G download speeds. You have to call WOW support to have it setup. Also, make sure they tune it properly so you get your full bandwidth. My tech had to put me on hold a couple of times to get some settings adjusted.

Great modem ez to install great price for the speed .

i have comcast and did my research before buying a new modem. this s the one that in my opinion and found by others opinion works the best. i had the last model but had reached its end of its life and this one has worked with no problems and is easy to setup as well. a must for comcast to avoid paying a rental fee, why rent when you can own your own!
