When we got a SMART TV in an area supported by Spectrum, I had to upgrade the old SURFboard to one that could handle streaming. The replacement was largely plug-and-play. The only issue involved the quality of the incoming coax from the outside pole, The new SURFboard had sufficient information for Spectrum to diagnose that the problem with speed was with the coax external to the house so they dispatched a technician to replace the cable at their expense. It was a single trip due partially to the capabilities of the SURFboard!

This modem was used to replace the standard cable co. Modem and will pay for itself in about a year, very easy to setup and very fast internet. Does not have voip tele. jack.

Upgraded from a previous 100MB to this speed demon. So far, so good. I don't expect to have to buy another router until somebody comes up with terabyte speeds.

Why rent when you can own. This little jewel will pay for itself in less than a year. Set up was like falling off a log get started and everything else falls into place.

Works properly, I was a little wary of it but I've tested it and it's working well while its predecessor has some real problems

This Arris modem worked absolutely fine for my son's studio apartment in northwest Arkansas with Cox Communications. I give ease of use a 4 because the technical resource at Cox had to do something on his end to activate the modem, telling me the Arris SURFboards during activation do a reset the other modems do not. But I have not had that problem with my own SURFboard in my city with my internet provider, so maybe this is a Cox-specific issue. Once activated properly, the modem has been steady and dependable.

Cheaper than renting the modem for a year, even with the Best Buy warranty. Just make sure your Internet provider is compatible

This device connected pretty easily and does what i brought it for. for some reason Optimum still doesn't see it on my account but it still works. coupled with the eero router have much better speed .

I got the notice from Xfinity about upgrading my modem and decided to do it since I have been using the SB6121 for a few years. Sales person at Best Buy recommended the SB6190, so I check out the reviews and bought it. Before disconnecting the SB6121, I ran the Xfinity speed test. My download speed was 93.88 Mbps and upload speed was 12.09Mbps. With the SB6190, my download speed came in at 93.35 Mbps and upload speed was 12.02 Mbps. Basically, no significant differences. For me, this was not a great upgrade as I probably could have used the SB6121 for at least another year.

Awesome equipment. Helped us a lot with our internet requirements in order to improve speeds and have better connections.

I just upgraded from the SB6121 as I was having stability issues with my connectiom. The SB6190 not only improved my speeds a bit, but it maintains the speed consistently.

It has been 4 months now, and no problem at all. If you want your high-end router work at the fastest speed, upgrade your modem.

Very easy to set up. Connect your cat5e cable to router, rg6 coax, then plug in power. Simple. Never had problems. But make sure it's compatible with your cable provider.

Getting easy 250+ MBPS now.. use it on Comcast. Upgraded router as well for this speed plan btw. Highly recommended as long as you don't need it for TELEPHONE service.

What can I say? Take it out of the box, hook up the cables, plug it in, have the ISP guys register the MAC address - Boom, it works.

Excellent modem. Solid performance. Bought this to replace modem that we were using from Cox.

Great product set up easy. replace this modem no longer paying for cable modem best thing I could’ve done only wish I had done it sooner.

This modem works for me with Spectrum. Previously they were charging me $5 a month for their modem. With this purchase I was able to save the $5 a month.

got this modem and a router so I don't have to pay the cable company. I just connected it, called the cable company and gave them the mac id and that was it. easy install.

No more throwing out money by renting it from Xfinity now I own my own and can use it with any cable provider. Never had an issue with this modem.
